The Hubble constant is determined through obtaining the angular diameter distance to the last scattering surface. That's not a direct observable; instead it's inferred through trigonometry. We can directly measure the angular scale of the Baryon Acoustic oscillations in the CMB – it's the distance between troughs in the power spectrum. In the standard $\Lambda$CDM cosmological model, we also know the physical scale of the BAO feature, known as the sound horizon length. The angular diameter distance is then defined as

$D_A = \frac{r_s}{\theta_s}$

where the numerator is the known physical scale and the denominator is the measured angular scale. The angular diameter distance is a well-known function of the Hubble rate, and you can infer the Hubble rate from getting the angular diameter distance (assuming the only pertinent species of particles in the universe are dark matter, baryons, photons, neutrinos, and the cosmological constant). In particular, the equation is

$\int_0^{z^*}$

$D_A = \int_0^{z^*}$

$ D_A = \int_0^{z^*} $

$ D_A = \frac{1}{1+z^*} \frac{dz}{H(z)} $

$ D_A = \frac{1}{1+z^*} \int_0 \frac{dz}{H(z)} $ (works)

$D_A = \frac{1}{1+z^*} \int_0 \frac{dz}{H(z)}$ (works)

$D_A = \frac{1}{1+z^*} \int_0^z \frac{dz}{H(z)}$ (works) $D\_A = \frac{1}{1+z^*} \int_0^z \frac{dz}{H(z)}$

$D_A = \frac{1}{1+z^*} \int_0^{z^1} \frac{dz}{H(z)}$ (works) $D\_A = \frac{1}{1+z^1} \int_0^{z^1} \frac{dz}{H(z)}$

$D_A = \frac{1}{1+z^*} \int_0^{z*} \frac{dz}{H(z)}$ (works) $D\_A = \frac{1}{1+z^\*} \int_0^{z\*} \frac{dz}{H(z)}$

$D_A = \frac{1}{1+z^*} \int_0^{z^*} \frac{dz}{H(z)}$ (works) $D\_A = \frac{1}{1+z^\*} \int_0^{z^\*} \frac{dz}{H(z)}$

$D_A = \frac{1}{1+z^} \int_0^{z^} \frac{dz}{H(z)}$ (does not work) $D\_A = \frac{1}{1+z^*} \int_0^{z^*} \frac{dz}{H(z)}$

$ D_A = \frac{1}{1+z^} \int_0^{z^} \frac{dz}{H(z)} $ (does not work) \$ D\_A = \frac{1}{1+z^*} \int_0^{z^*} \frac{dz}{H(z)} \$

$H(z) = H_0 \sqrt{\Omega_m (1+z)^3 + \Omega_{rad} (1+z)^4 + \Omega_{\Lambda}}$

with $z^*$ is the redshift of the CMB (~1100), and the $\Omega$ density parameters corresponding to the known total matter density, radiation density, and vacuum energy density today, respectively.

Drivers are required to yield the right-of-way to pedestrians within any crosswalk, whether marked or unmarked. [Pedestrian Responsibilities; Miscellaneous Licensing Information]

Special “turnout” areas are sometimes marked on two-lane roads. Drive into these areas to allow cars behind you to pass. If you are driving slowly on a two-lane highway or road where passing is unsafe, and five or more vehicles are following you, you must drive into a turnout area to let the vehicles pass. [Turnout Areas and Lanes; Lane Controls]

If you hit a parked vehicle or other property, you must leave a note with your name and address, the name and address of the owner of your vehicle, and a description of the collision.

[Involved in a Collision; Collisions Are Not Accidents]

Broken white lines indicate that passing is allowed but only when it can be done safely. [Line Colors; Lane Controls]

Most rear-end collisions are caused by tailgating. To avoid tailgating, use the “three-second rule”: When the vehicle ahead of you passes a certain fixed point, such as a sign, it should take your vehicle about three seconds to reach that same point. To count three seconds, count “one-thousand-one, one-thousand-two, one-thousand-three.” [Do Not Be a Tailgater!; Know What is Ahead; Visual Search]

You must turn on your headlights 30 minutes after sunset and leave them on until 30 minutes before sunrise. [Things You Must Do; Additional Driving Laws/Rules]

At intersections, yield to the vehicle or bicycle that arrives first, or to the vehicle or bicycle on your right if it reaches the intersection at the same time as you do. [Bicycles in Travel Lanes; Sharing the Road]

If drivers see animals or livestock, they should slow down and follow directions from the person in charge of the animals. [Near Animals; Laws and Rules of the Road]

Diamond-shaped placards on a truck mean that the truck is carrying hazardous materials (gas, explosives, etc.).

Two sets of solid double yellow lines spaced two or more feet apart are considered a barrier. Do not drive on or over this barrier or make a left turn or U-turn across it, except at designated openings. [Line Colors; Lane Controls]

A flashing yellow arrow signal means that turns are permitted. However, you must first yield to pedestrians and oncoming traffic and then proceed with caution. [Traffic Signal Lights; Traffic Controls]

A double solid white line separates two lanes traveling in the same direction, but crossing the line is prohibited. Double solid white lines are often used on highways to separate a high-occupancy vehicle (HOV) lane from other lanes traveling in the same direction. [Line Colors; Lane Control]

A solid white line between lanes of traffic means that you should stay in your lane unless a special situation requires you to change lanes. [Line Colors; Lane Control]

When you are involved in a collision, you must report it to the DMV within 10 days, if more than $1,000 in damage was done to the property of any person or if anyone was injured (no matter how slightly) or killed. [Reporting a Collision; Collisions Are Not Accidents]

If your vehicle starts to hydroplane, slow down gradually, but do not apply the brakes. [Driving Hazards; Special Driving Situations]

If you brake hard at a high speed, the force of the brakes may exceed the tires' grip of the road. The wheels will lock and the vehicle will skid, no matter which way the steering wheel is turned. To recover from the skid, take your foot off the brake pedal to unlock the wheels. Then straighten the front wheels as the vehicle begins to straighten out. Slow the vehicle gradually until you are at a safe speed to continue driving. [Locked Wheel Skids; Handling Emergencies]

However, if you must drive in fog, drive slowly and use your low-beam headlights. The light from high beams will tend to reflect back and cause glare. [Use Your Headlights; Safe Driving Practices]

Turning on your right turn signal lets the officer know that you recognize his or her presence. Do not stop on the center median. [What a Driver Should Do During an Enforcement Stop; Special Driving Situations]

a yield sign, a red-and-white triangle pointing downward. It indicates that drivers must slow down and be ready to stop, if necessary, to let any vehicle or pedestrian pass.

At 55 mph, under good conditions, your vehicle will travel about 400 feet in the time that it takes you to react to an object in your path and bring your vehicle to a complete stop. A football field (including the two end zones) is 360 feet long. Under poor driving conditions (bad weather, bad tires, etc.), it may take even longer to stop your vehicle.

U-turns are permitted across double yellow lines when it is safe to do so. They are not permitted on one-way streets or at railroad crossings. [Line Colors; Lane Control]

You should cut your speed in half when the road is packed with snow. You should also reduce your speed on wet or icy roads, but by different amounts. [Driving in Rain or Snow; Special Driving Situations]

Yellow lines are also used as left-edge lines on one-way roadways.

Two solid yellow lines indicate no passing. You may not cross these lines except to make a left turn. However, in California, there is one exception to this usual rule: You may drive to the left of these lines if you are in a carpool/HOV lane that has a designated entrance on the left. [Line Colors; Lane Control]

You must not follow within 300 feet of any emergency vehicle with a siren or flashing lights. The length of a football playing field (i.e., without the two end zones) is 300 feet. [Emergency Vehicles; Sharing the Road]

Any person, while operating a motor vehicle, who willfully flees or attempts to evade a peace officer performing their duties is guilty of a misdemeanor punishable by imprisonment in a county jail for not more than one year. [Evading a Peace Officer; Administrative]

A white line separates two lanes traveling in the same direction. If it's a broken line, you may cross it to pass or change lanes. If it's a solid line, you should usually stay in your lane.

The right edges of many roadways are marked with a solid white line. This line indicates the outer edge of the roadway, and it may be crossed only by traffic moving to or from the shoulder. The left edge is marked with a yellow line. [Line Colors; Lane Control]

In California, reckless driving is defined as driving in wanton disregard for the safety of persons or property, and it's a criminal offense. If you are convicted of reckless driving, you will be fined beween $145 and $1,000, sentenced to jail for 5 to 90 days, or both; and two points will be added to your driving record. However, if you are convicted of reckless driving that resulted in injury to someone, you will be fined beween $220 and $1,000, sentenced to jail for between 30 days and six months, or both; your license will be revoked; and two points will be added to your driving record. [Speed Contests/Reckless Driving, Administrative, California Driver Handbook], [CVC § 23103], [CVC § 23104]

In California, you must not park within 7½ feet of a railroad track. (Note that trains are at least six feet wider than the tracks they run on.) [Illegal Parking; Parking]

a center left-turn lane. It is marked by parallel solid and broken yellow lines and is sometimes accompanied by white arrows on the pavement. [Center Left Turn Lanes; Lane Control; California Driver Handbook]

Distracted driving may lead to a collision. Stay as far away as possible from distracted drivers.

A limit line (also known as a stop line) is a wide white line painted across a traffic lane, showing where you must stop for a traffic signal or stop sign. (NOT A CROSSWALK LINE)

When you park and leave your vehicle on a highway or street, roll up the windows, stop the engine, lock the ignition, remove the key, set the parking brake (even if your car has an automatic transmission), and lock the doors. [Vehicle Theft Prevention Tips

Intersections are the most likely places for car/motorcycle collisions to occur.

Use your high beams whenever there are no oncoming vehicles nearby. High beams allow you to see twice as far as low beams. Be sure to use high beams on unfamiliar roads, in construction areas, or where there may be people on the side of the road. However, use low beams in fog, snow, or heavy rain, because light from the high beams reflects off such precipitation and causes glare.

An intersection is considered “blind” if there are no stop signs on any corner and you cannot see for 100 feet in either direction during the last 100 feet before crossing. In California, the speed limit for going through a blind intersection is 15 mph. [Reduced Speeds; Speed Limits;

This sign indicates that all vehicles must go straight. No turn from this lane is allowed. [White Regulatory Signs; Traffic Signs; Traffic Controls;

Regulatory devices tell you to stop, proceed in a certain direction, or limit your speed. All regulatory devices indicate actions required by the driver. Failure to comply is subject to penalty. [Regulatory Signs; Traffic Signs; Traffic Controls;

If you are overtaking a bicycle and an oncoming vehicle is approaching, you must slow down and let the vehicle pass first. Then you can leave extra room for the bicycle.

The first rule for a safe and legal turn is to move into the proper lane well before the turn. To turn left, move into the far left lane. To turn right, move into the far right lane. [Turns; Lane Control

If you are approaching a stop sign, you must stop at the solid white limit line (also known as a stop line). If there is no limit line, stop before entering the crosswalk on your side of the intersection.

Hills and curves on rural roads are often steeper and sharper than on highways. Before reaching the crest of a hill or before entering a curve, slow down, move to the right side of the road, and watch for oncoming vehicles.

If you plan to turn beyond an intersection, start signaling when you are in the intersection. If you signal too early, the other driver may think you plan to turn into the intersection and he or she may pull out in front of you.

When you turn off a high-speed, two-lane roadway, try not to slow down too quickly. Use your turn signals to let other drivers know your intentions. Tap your brakes and reduce your speed quickly but safely. [Space to Merge; Vehicle Positioning;

You should not attempt to pass another vehicle when you are approaching or moving through an intersection or crosswalk. [Passing Lanes; Lane Control;

White lines separate lanes of traffic that are going in the same direction. Yellow lines separate opposing lanes. [Examples of Lane Markings; Lane Control;

Motorcyclists need a full lane width, just like other vehicles. Car drivers should never drive alongside a motorcycle in the same lane even if the lane is wide and the motorcyclist is riding to one side.

Narrow streets are a source of crashes. Unless it is prohibited, drivers must use the three-point turn to turn around on a narrow street.

Single solid yellow lines are used as left-edge lines on divided highways.

A steady yellow light indicates that a red light is coming next. You must stop if you can do so safely. Otherwise, slow down, proceed with caution into the intersection, and then clear the intersection. [Traffic Signal Lights; Traffic Controls;

An interchange is the connection of a freeway to a road or another freeway by a series of ramps. The connecting roadways allow you to leave one road and enter another safely without disrupting the flow of traffic. [Know What is Ahead; Visual Search

A steady yellow arrow warns drivers that the time period of “protected” turning is ending. Be prepared to obey the next signal, which could be a green or red light or a red arrow. If you are approaching the intersection, you must stop. [Traffic Signal Lights; Traffic Controls;

If a driver extends his or her left arm out horizontally, it means that the driver is going to make a left turn.

When turning right into a two-way street, begin and end the turn in the lane nearest to the right edge of the road.

3 left-arrow flashing arrow panel: This sequential arrow panel may be used in work zones around the clock. It indicates that part of the road or street ahead is closed.

When you are parallel parked on the right-hand side of the street, you must signal a left turn and look over your left shoulder before pulling out into traffic. If you are parallel parked on the left-hand side of a one-way street, signal a right turn and look over your right shoulder before moving into traffic.

On a two-way roadway with a center lane, drivers from either direction can _________ from the center lane. Drivers from either direction may use the center lane for left turns and permitted U-turns. [Examples of Right and left Turns; Turns; Lane Control

A sign shaped like a downward-pointing triangle is a yield sign. When you see a yield sign, you must slow down and yield to approaching traffic.

With any turning vehicle, the rear wheels follow a shorter path than the front wheels. The longer the vehicle is, the greater the difference will be. Trucks and other large vehicles may initially swing out before making a turn. If you see a truck move left, don't try to pass it on its right; the truck may be about to turn right. Check its turn signals.

A triangular orange emblem on the rear of a vehicle identifies it as a slow-moving vehicle, which California defines as a vehicle that cannot travel faster than 25 mph. Slow-moving vehicles are required by law to display this emblem. Slow-moving vehicles include farm tractors and road maintenance vehicles.

A variety of vehicles can flash yellow lights. Flashing yellow lights on tow trucks and slow-moving vehicles warn you to slow down. However, some school buses flash yellow lights when preparing to stop to let children on or off the bus. These lights warn you to slow down and prepare to stop. When the school bus flashes red lights, you must stop and remain stopped until the children have left and the red lights stop flashing.

Double solid yellow lines mark the center of a road and separate opposing lanes. Passing is not allowed in either direction. Drivers may not cross the lines unless they are making a left turn. [Line Colors; Lane Controls;

When adjusting your seat, you should allow 10” between the chest and steering wheel.

If you double your speed on a highway, your braking distance increases by 4 times.

An average 140-pound woman will become legally intoxicated after consuming 2 alcoholic drink(s). An average 180-pound man will become legally intoxicated after consuming 2 alcoholic drinks.

A white line separates two lanes traveling in the same direction. If it's a broken line, you may cross it to pass or change lanes. If it's a solid line, you should usually stay in your lane.

This is an object marker sign, which is used to notify drivers of objects in the roadway or very close to the edge of the roadway. The stripes point downward toward the safe side of the roadway. This sign indicates that you should keep right to pass the object.

Upgrade to 17.0 from 16.0.5 | Nextcloud notes | nc Docker notes |

Install procedures were customized from this nextcloud source.

The native Debian install had lot of cautionary messages in admin Overview panel but the Docker version just had these. Followup with this article.

The “X-Content-Type-Options” HTTP header is not set to “nosniff”. This is a potential security or privacy risk, as it is recommended to adjust this setting accordingly.
The “X-Frame-Options” HTTP header is not set to “SAMEORIGIN”. This is a potential security or privacy risk, as it is recommended to adjust this setting accordingly.
The “Strict-Transport-Security” HTTP header is not set to at least “15552000” seconds. For enhanced security, it is recommended to enable HSTS as described in the security tips ↗.

Docker container Nextcloud self-signed SSL certificate info -——

2019-09-10 Initially used a Docker container for Nextcloud, but I later thought it was too much of a hassle to keep it up to date and rebuilding it for updates which involved numerous layered images. So I decided to try a native install with Apache, PHP, and Sqlite3.
First installed Apache 2.4.25 default debian package
Installed the sury.org php 7.3.9 package (cat /etc/apt/sources.list.d/ondrej.list). See linuxize instructions.
Created a self-signed SSL certificate. The initial SSL self-signed certificate creation worked in Docker nextcloud container, but did not work when I next installed apache2 on compute-engine and tried to set up https. Couldn't get it to work or figure out why it didn't work. So I completely removed apache2, and the apache self-signed certificate in /etc/ssl/certs. Then made a copy of the following files from docker nextcloud container: 000-default.conf apache-selfsigned.crt apache-selfsigned.key default-ssl.conf ssl-params.conf. Then redid the procedures with those files and using these procedures. This worked!

2019-09-20 Did a manual install of nextcloud 16.04.1 on Google Compute Engine, Debian 9 instance using these instructions.

Prerequisites for manual installation

The Nextcloud .tar or .zip archive contains all of the required PHP modules. This section lists all required and optional PHP modules. Consult the PHP manual for more information on modules. Your Linux distribution should have packages for all required modules. You can check the presence of a module by typing php -m | grep -i . If you get a result, the module is present.

Required:

PHP (7.1, 7.2 or 7.3)
PHP module ctype
PHP module curl
PHP module dom
PHP module GD
PHP module iconv
PHP module JSON
PHP module libxml (Linux package libxml2 must be >=2.7.0)
PHP module mbstring
PHP module openssl
PHP module posix
PHP module session
PHP module SimpleXML
PHP module XMLReader
PHP module XMLWriter
PHP module zip
PHP module zlib

Database connectors (pick the one for your database:)

PHP module pdo_sqlite (>= 3, usually not recommended for performance reasons)
PHP module pdo_mysql (MySQL/MariaDB)
PHP module pdo_pgsql (requires PostgreSQL >= 9.0)

Recommended packages:

PHP module fileinfo (highly recommended, enhances file analysis performance)
PHP module bz2 (recommended, required for extraction of apps)
PHP module intl (increases language translation performance and fixes sorting of non-ASCII characters)

Required for specific apps:

PHP module ldap (for LDAP integration)
PHP module smbclient (SMB/CIFS integration, see SMB/CIFS)
PHP module ftp (for FTP storage / external user authentication)
PHP module imap (for external user authentication)

Recommended for specific apps (optional):

PHP module exif (for image rotation in pictures app)
PHP module gmp (for SFTP storage)

For enhanced server performance (optional) select one of the following memcaches:

PHP module apcu (>= 4.0.6)
PHP module memcached
PHP module redis (>= 2.2.6, required for Transactional File Locking)

See Memory caching to learn how to select and configure a memcache.

For preview generation (optional):

PHP module imagick
avconv or ffmpeg
OpenOffice or LibreOffice

For command line processing (optional): – PHP module pcntl (enables command interruption by pressing ctrl-c)

After completion and everything working, these are the installed PHP packages (php -m): curl, date, dom, exif, fileinfo, filter, ftp, gd, gettext, hash, iconv, imagick, json, libxml, mbstring, mysqli, mysqlnd, openssl, pcntl, pcre, PDO, pdo_mysql, pdo_sqlite, Phar, posix, readline, Reflection, session, shmop, SimpleXML, sockets, sodium, SPL, sqlite3, standard, sysvmsg, sysvsem, sysvshm, tokenizer, wddx, xml, xmlreader, xmlwriter, xsl, Zend OPcache, zip, zlib, [Zend Modules], Zend OPcache

Loaded Apache modules (sudo apachectl -M): core_module (static), so_module (static), watchdog_module (static), http_module (static), log_config_module (static), logio_module (static), version_module (static), unixd_module (static), access_compat_module (shared), alias_module (shared), auth_basic_module (shared), authn_core_module (shared), authn_file_module (shared), authz_core_module (shared), authz_host_module (shared), authz_user_module (shared), autoindex_module (shared), deflate_module (shared), dir_module (shared), env_module (shared), filter_module (shared), headers_module (shared), mime_module (shared), mpm_prefork_module (shared), negotiation_module (shared), php7_module (shared), reqtimeout_module (shared), rewrite_module (shared), setenvif_module (shared), socache_shmcb_module (shared), ssl_module (shared), status_module (shared)

You don't need the WebDAV module for your Web server (i.e. Apache's mod_webdav), as Nextcloud has a built-in WebDAV server of its own, SabreDAV. If mod_webdav is enabled you must disable it for Nextcloud. (See Apache Web server configuration for an example configuration.)

Example installation on Ubuntu 18.04 LTS server

On a machine running a pristine Ubuntu 18.04 LTS server, you have three options:

For (1) bash scripts and (2) snap packages, see original nextcloud install procedures

(3) Debian packages: Installing Nextcloud

Or you can use .deb packages to install the required and recommended modules for a typical Nextcloud installation, using Apache and MariaDB, by issuing the following commands in a terminal:

apt-get install apache2 mariadb-server libapache2-mod-php7.3 apt-get install php7.3-gd php7.3-json php7.3-mysql php7.3-curl php7.3-mbstring apt-get install php7.3-intl php-imagick php7.3-xml php7.3-zip

This installs the packages for the Nextcloud core system. libapache2-mod-php7.3 provides the following PHP extensions:

bcmath bz2 calendar Core ctype date dba dom ereg exif fileinfo filter ftp gettext hash iconv libxml mhash openssl pcre Phar posix Reflection session shmop SimpleXML soap sockets SPL standard sysvmsg sysvsem sysvshm tokenizer wddx xmlreader xmlwriter zlib

If you are planning on running additional apps, keep in mind that they might require additional packages. See Prerequisites for manual installation for details.

At the installation of the MySQL/MariaDB server, you will be prompted to create a root password. Be sure to remember your password as you will need it during Nextcloud database setup.

Now download the archive of the latest Nextcloud version:

Go to the Nextcloud Download Page.
Go to Download Nextcloud Server > Download > Archive file for server owners and download either the tar.bz2 or .zip archive.
This downloads a file named nextcloud-x.y.z.tar.bz2 or nextcloud-x.y.z.zip (where x.y.z is the version number).
Download its corresponding checksum file, e.g. nextcloud-x.y.z.tar.bz2.md5, or nextcloud-x.y.z.tar.bz2.sha256.
Verify the MD5 or SHA256 sum:

md5sum -c nextcloud-x.y.z.tar.bz2.md5 < nextcloud-x.y.z.tar.bz2 sha256sum -c nextcloud-x.y.z.tar.bz2.sha256 < nextcloud-x.y.z.tar.bz2 md5sum -c nextcloud-x.y.z.zip.md5 < nextcloud-x.y.z.zip sha256sum -c nextcloud-x.y.z.zip.sha256 < nextcloud-x.y.z.zip
You may also verify the PGP signature:

wget https://download.nextcloud.com/server/releases/nextcloud-x.y.z.tar.bz2.asc wget https://nextcloud.com/nextcloud.asc gpg --import nextcloud.asc gpg --verify nextcloud-x.y.z.tar.bz2.asc nextcloud-x.y.z.tar.bz2
Now you can extract the archive contents. Run the appropriate unpacking command for your archive type. Copy the content over to the root directory of your webserver. In our case, we are using apache so it will be /var/www/html/:

tar -xjf nextcloud-x.y.z.tar.bz2
unzip nextcloud-x.y.z.zip (I did the zip file) Or: unzip nextcloud-*.zip
This unpacks to a single nextcloud directory. Copy the Nextcloud directory to its final destination.

cp -rp nextcloud /var/www/html (I did this; it copies with recursion preserving mode, ownership, timestamps) Or with the tar file in /var/www/html, just unzip it.

During the install process, no data folder is created, so we will create one manually to help with the installation wizard: mkdir /var/www/html/nextcloud/data

Make sure that apache has read and write access to the whole nextcloud folder:

chown -R www-data:root /var/www/html/nextcloud (this duplicated the Docker ownership; it did not work as root:root). Note that the nextcloud data folder and all files in it have www-data:www-data ownership.

Restart apache: sudo systemctl restart apache2

Create a firewall rule for access to apache:

firewall-cmd --zone=public --add-service=http --permanent firewall-cmd --reload

Note: If you use this tutorial, and you see warnings in the web browser after installation about OPcache not being enabled or configured correctly, you need to make the suggested changes in /etc/opt/rh/rh-php72/php.d/10-opcache.ini for the errors to disappear. These warnings will be on the Admin page, under Basic settings.

Because we used Redis as a memcache, you will need a config similar to the following example in /var/www/html/nextcloud/config/config.php which is auto-generated when you run the online installation wizard mentioned earlier.

Example config:

'memcache.distributed' => '\OC\Memcache\Redis', 'memcache.locking' => '\OC\Memcache\Redis', 'memcache.local' => '\OC\Memcache\APCu', 'redis' => array( 'host' => 'localhost', 'port' => 6379, ),

Remember, this tutorial is only for a basic setup of Nextcloud with PHP 7.3. If you are going to use more features like LDAP or Single Sign On, you will need additional PHP modules as well as extra configurations. So please visit the rest of the Admin manual, Introduction, for detailed descriptions on how to get this done.

Apache Web server configuration

On Debian, Ubuntu, and their derivatives, Apache installs with a useful configuration so all you have to do is create a /etc/apache2/sites-available/nextcloud.conf file with these lines in it, replacing the Directory and other filepaths with your own filepaths: Alias /nextcloud "/var/www/nextcloud/"


  Require all granted
  Options FollowSymlinks MultiViews
  AllowOverride All

 
  Dav off
 

 SetEnv HOME /var/www/nextcloud
 SetEnv HTTP_HOME /var/www/nextcloud

Then enable the newly created site: a2ensite nextcloud.conf

Additional Apache configurations

For Nextcloud to work correctly, we need the module mod_rewrite. Enable it by running: a2enmod rewrite

Additional recommended modules are mod_headers, mod_env, mod_dir and mod_mime:

a2enmod headers a2enmod env a2enmod dir a2enmod mime

If you're running mod_fcgi instead of the standard mod_php also enable: a2enmod setenvif
You must disable any server-configured authentication for Nextcloud, as it uses Basic authentication internally for DAV services. If you have turned on authentication on a parent folder (via e.g. an AuthType Basic directive), you can turn off the authentication specifically for the Nextcloud entry. Following the above example configuration file, add the following line in the section:

Satisfy Any
When using SSL, take special note of the ServerName. You should specify one in the server configuration, as well as in the CommonName field of the certificate. If you want your Nextcloud to be reachable via the internet, then set both of these to the domain you want to reach your Nextcloud server.
Now restart Apache: sudo systemctl restart apache2
If you're running Nextcloud in a subdirectory and want to use CalDAV or CardDAV clients make sure you have configured the correct Service discovery URLs.

Pretty URLs (I didn't do this)

Pretty URLs remove the index.php-part in all Nextcloud URLs, for example in sharing links like https://example.org/nextcloud/index.php/s/Sv1b7krAUqmF8QQ, making URLs shorter and thus prettier.

mod_env and mod_rewrite must be installed on your webserver and the .htaccess must be writable by the HTTP user. Then you can set in the config.php two variables:

'overwrite.cli.url' => 'https://example.org/nextcloud', 'htaccess.RewriteBase' => '/nextcloud',

If your setup is available on https://example.org/nextcloud or:

'overwrite.cli.url' => 'https://example.org/', 'htaccess.RewriteBase' => '/',

if it isn't installed in a subfolder. Finally run this occ-command to update your .htaccess file:

sudo -u www-data php /var/www/nextcloud/occ maintenance:update:htaccess

After each update, these changes are automatically applied to the .htaccess-file.

Enabling SSL

These procedures worked for a self-signed SSL certificate.

You can use Nextcloud over plain HTTP, but we strongly encourage you to use SSL/TLS to encrypt all of your server traffic, and to protect user's logins and data in transit.

Apache installed under Ubuntu comes already set-up with a simple self-signed certificate. All you have to do is to enable the ssl module and the default site (this is probably the snake oil certificate?). Open a terminal and run:

a2enmod ssl a2ensite default-ssl service apache2 reload

Self-signed certificates have their drawbacks – especially when you plan to make your Nextcloud server publicly accessible. You might want to consider getting a certificate signed by a commercial signing authority. Check with your domain name registrar or hosting service for good deals on commercial certificates.

Installation wizard

After restarting Apache you must complete your installation by running either the graphical Installation Wizard, or on the command line with the occ command. To enable this, change the ownership on your Nextcloud directories to your HTTP user:

chown -R www-data:www-data /var/www/nextcloud/ (see note above re the ownerships I actually used, which were the same as in the Docker container)

Note

To use occ see Installing from command line.

To use the graphical Installation Wizard see Installation wizard.

The docker daemon will store that data within the docker directory /var/lib/docker/volumes/.... That means your data is saved even if the container crashes, is stopped or deleted.

A named Docker volume or a mounted host directory should be used for upgrades and backups. To achieve this you need one volume for your database container and one for Nextcloud.

CONVERTING TEXT FORMATS WITH PANDOC (Pandoc site) One of my favorite tools is Pandoc. I use Pandoc when I need to convert one text format to another. One of the really useful things Pandoc can do is turn HTML or Markdown into EPUB format. I frequently do this in order to turn a set of notes into a file I can read using iBooks on my iPad. I do this in order to have an easily accessible set of notes for my workshops or to turn lengthy documentation into an easy to read offline format to read on an airplane. Pandoc can convert from and to many different file formats. In addition to creating quick EPUB files, I also use it to convert copy from Word documents to Markdown or other useful formats. This can be very useful if you get some messy copy from a client that needs to be converted to enter into a CMS. from: https://www.smashingmagazine.com/2018/07/text-editing-tips-tricks/ Also see: Converting html to markdown using pandoc How to Use pandoc to Convert Files on the Linux Command Line
