We've tried very hard to ensure that Friendica will run on commodity hosting platforms - such as those used to host Wordpress blogs and Drupal websites. We offer a manual and an automatic installation. But be aware that Friendica is more than a simple web application.
It is a complex communications system which more closely resembles an email server than a web server. For reliability and performance, messages are delivered in the background and are queued for later delivery when sites are down. This kind of functionality requires a bit more of the host system than the typical blog.
Not every PHP/MySQL hosting provider will be able to support Friendica. Many will.
But please review the requirements and confirm these with your hosting provider prior to installation.
If you encounter installation issues, please let us know via the helper or the developer forum or file an issue.
Please be as clear as you can about your operating environment and provide as much detail as possible about any error messages you may see, so that we can prevent it from happening in the future. Due to the large variety of operating systems and PHP platforms in existence we may have only limited ability to debug your PHP installation or acquire any missing modules - but we will do our best to solve any general code issues.
- Choose a domain name or subdomain name for your server. Put some thought into this. While changing it after installation is supported, things still might break.
- Setup HTTPS on your domain.
- Apache with mod-rewrite enabled and "Options All" so you can use a local
.htaccessfile - PHP 7.3+ (PHP8 is not fully supported yet)
- PHP command line access with register_argc_argv set to true in the php.ini file
- Curl, GD, PDO, mbstrings, MySQLi, hash, xml, zip and OpenSSL extensions
- The POSIX module of PHP needs to be activated (e.g. RHEL, CentOS have disabled it)
- Some form of email server or email gateway such that PHP mail() works. If you cannot set up your own email server, you can use the phpmailer addon and use a remote SMTP server.
- MySQL 5.6+ or an equivalent alternative for MySQL (MariaDB, Percona Server etc.)
- ability to schedule jobs with cron (Linux/Mac) or Scheduled Tasks (Windows)
- installation into a top-level domain or sub-domain (without a directory/path component in the URL) is RECOMMENDED. Directory paths will not be as convenient to use and have not been thoroughly tested. This is REQUIRED if you wish to communicate with the Diaspora network.
If your hosting provider doesn't allow Unix shell access, you might have trouble getting everything to work.
For alternative server configurations (such as Nginx server and MariaDB database engine), refer to the Friendica wiki.
- PHP ImageMagick extension (php-imagick) for animated GIF support.
This guide will walk you through the manual installation process of Friendica. If this is nothing for you, you might be interested in
- the Friendica Docker image or
- how to install Friendica with YunoHost.
Download the full archive of the stable release of Friendica core and the addons from the project homepage. Make sure that the version of the Friendica archive and the addons match. Unpack the Friendica files into the root of your web server document area.
If you copy the directory tree to your webserver, make sure that you also copy .htaccess-dist - as "dot" files are often hidden and aren't normally copied.
OR
Clone the friendica/friendica GitHub repository and import dependencies. This makes the software much easier to update.
The Linux commands to clone the repository into a directory "mywebsite" would be
git clone https://github.com/friendica/friendica.git -b stable mywebsite
cd mywebsite
bin/composer.phar install --no-dev
Make sure the folder view/smarty3 exists and is writable by the webserver user, in this case www-data
mkdir -p view/smarty3
chown www-data:www-data view/smarty3
chmod 775 view/smarty3
Get the addons by going into your website folder.
cd mywebsite
Clone the addon repository (separately):
git clone https://github.com/friendica/friendica-addons.git -b stable addon
If you want to use the development version of Friendica you can switch to the develop branch in the repository by running
git checkout develop
bin/composer.phar install
cd addon
git checkout develop
Be aware that the develop branch is unstable and may break your Friendica node at any time. You should have a recent backup before updating. If you encounter a bug, please let us know.
Create an empty database and note the access details (hostname, username, password, database name).
Friendica needs the permission to create and delete fields and tables in its own database.
Please check the troubleshooting section if running on MySQL 5.7.17 or newer.
Before you point your web browser to the new site you need to copy .htaccess-dist to .htaccess for Apache installs.
Follow the instructions.
Please note any error messages and correct these before continuing.
If you need to specify a port for the connection to the database, you can do so in the host name setting for the database.
If the manual installation fails for any reason, check the following:
- Does
config/local.config.phpexist? If not, editconfig/local-sample.config.phpand change the system settings. - Rename to
config/local.config.php. - Is the database populated? If not, import the contents of
database.sqlwith phpmyadmin or the mysql command line.
At this point visit your website again, and register your personal account.
Registration errors should all be recoverable automatically.
If you get any critical failure at this point, it generally indicates the database was not installed correctly.
You might wish to move/rename config/local.config.php to another name and empty (called 'dropping') the database tables, so that you can start fresh.
You have the following options to automatically install Friendica:
- creating a prepared config file (f.e.
prepared.config.php) - using environment variables (f.e.
MYSQL_HOST) - using options (f.e.
--dbhost <host>)
You can combine environment variables and options, but be aware that options are prioritized over environment variables.
For more information during the installation, you can use this command line option
bin/console autoinstall -v
If you wish to include all optional checks, use -a like this statement:
bin/console autoinstall -a
If the automatic installation fails for any reason, check the following:
- Does
config/local.config.phpalready exist? If yes, the automatic installation won't start - Are the options in the
config/local.config.phpcorrect? If not, edit them directly. - Is the empty MySQL-database created? If not, create it.
You can use a prepared config file like local-sample.config.php.
Navigate to the main Friendica directory and execute the following command:
bin/console autoinstall -f <prepared.config.php>
There are two types of environment variables.
- those you can use in normal mode too (Currently just database credentials)
- those you can only use during installation (because Friendica will normally ignore it)
You can use the options during installation too and skip some of the environment variables.
Database credentials
if you don't use the option --savedb during installation, the DB credentials will not be saved in the config/local.config.php.
MYSQL_HOSTThe host of the mysql/mariadb databaseMYSQL_PORTThe port of the mysql/mariadb databaseMYSQL_USERNAMEThe username of the mysql database login (used for mysql)MYSQL_USERThe username of the mysql database login (used for mariadb)MYSQL_PASSWORDThe password of the mysql/mariadb database loginMYSQL_DATABASEThe name of the mysql/mariadb database
Friendica settings
This variables wont be used at normal Friendica runtime.
Instead, they get saved into config/local.config.php.
FRIENDICA_URL_PATHThe URL path of Friendica (f.e. '/friendica')FRIENDICA_PHP_PATHThe path of the PHP binaryFRIENDICA_ADMIN_MAILThe admin email address of Friendica (this email will be used for admin access)FRIENDICA_TZThe timezone of FriendicaFRIENDICA_LANGThe language of Friendica
Navigate to the main Friendica directory and execute the following command:
bin/console autoinstall [--savedb]
All options will be saved in the config/local.config.php and are overruling the associated environment variables.
-H|--dbhost <host>The host of the mysql/mariadb database (envMYSQL_HOST)-p|--dbport <port>The port of the mysql/mariadb database (envMYSQL_PORT)-U|--dbuser <username>The username of the mysql/mariadb database login (envMYSQL_USERorMYSQL_USERNAME)-P|--dbpass <password>The password of the mysql/mariadb database login (envMYSQL_PASSWORD)-d|--dbdata <database>The name of the mysql/mariadb database (envMYSQL_DATABASE)-u|--urlpath <url_path>The URL path of Friendica - f.e.

Navigate to the main Friendica directory and execute the following command:
bin/console autoinstall [options]
Copy .htaccess-dist to .htaccess (be careful under Windows) to have working mod-rewrite again. If you have installed Friendica into a sub directory, like /friendica/ set this path in RewriteBase accordingly.
Example:
cp .htacces-dist .htaccess
Note: Do not rename the .htaccess-dist file as it is tracked by GIT and renaming will cause a dirty working directory.
Friendica should respond automatically to important addresses under the /.well-known/ rewrite path.
One critical URL would look like, for example: https://example.com/.well-known/host-meta
It must be visible to the public and must respond with an XML file that is automatically customized to your site.
If that URL is not working, it is possible that some other software is using the /.well-known/ path. Other symptoms may include an error message in the Admin settings that says "host-meta is not reachable on your system. This is a severe configuration issue that prevents server to server communication." Another common error related to host-meta is the "Invalid profile URL."
Check for a .well-known directory that did not come with Friendica.
The preferred configuration is to remove the directory, however this is not always possible.
If there is any /.well-known/.htaccess file, it could interfere with this Friendica core requirement.
You should remove any RewriteRules from that file, or remove that whole file if appropriate.
It may be necessary to chmod the /.well-known/.htaccess file if you were not given write permissions by default.
At this point visit your website again, and register your personal account with the same email as in the config.admin_email config value.
Registration errors should all be recoverable automatically.
If you get any critical failure at this point, it generally indicates the database was not installed correctly.
You might wish to delete/rename config/local.config.php to another name and drop all the database tables so that you can start fresh.
Set up a cron job or scheduled task to run the worker once every 5-10 minutes in order to perform background processing. Example:
cd /base/directory; /path/to/php bin/worker.php
Change "/base/directory", and "/path/to/php" as appropriate for your situation.
If you are using a Linux server, run "crontab -e" and add a line like the one shown, substituting for your unique paths and settings:
*/10 * * * * cd /home/myname/mywebsite; /usr/bin/php bin/worker.php
You can generally find the location of PHP by executing "which php". If you run into trouble with this section please contact your hosting provider for assistance. Friendica will not work correctly if you cannot perform this step.
If it is not possible to set up a cron job then please activate the "frontend worker" in the administration interface.
Once you have installed Friendica and created an admin account as part of the process, you can access the admin panel of your installation and do most of the server wide configuration from there.
Otherwise, you’ll need to use the command line on your remote server and start the Friendica daemon (background task) using the following command:
cd /path/to/friendica; php bin/daemon.php start
Once started, you can check the daemon status using the following command:
cd /path/to/friendica; php bin/daemon.php status
After a server restart or any other failure, the daemon needs to be restarted. This could be achieved by a cronjob.
At this point it is recommended that you set up logging and logrotation. To do so please visit Settings and search the 'Logs' section for more information.
Bad things will happen. Let there be a hardware failure, a corrupted database or whatever you can think of. So once the installation of your Friendica node is done, you should make yourself a backup plan.
The most important file is the config/local.config.php file.
As it stores all your data, you should also have a recent dump of your Friendica database at hand, should you have to recover your node.
Friendica looks for some well-known HTTP headers indicating a reverse-proxy
terminating an HTTPS connection.
While the standard from RFC 7239 specifies the use of the Forwarded header.
Forwarded: for=192.0.2.1; proto=https; by=192.0.2.2
Friendica also supports a number on non-standard headers in common use.
X-Forwarded-Proto: https
Front-End-Https: on
X-Forwarded-Ssl: on
It is however preferable to use the standard approach if configuring a new server.
Check your database settings. It usually means your database could not be opened or accessed. If the database resides on the same machine, check that the database server name is "localhost".
This could be the result of one of our Apache directives not being supported by your version of Apache. Examine your apache server logs.
You might remove the line "Options -Indexes" from the .htaccess file if you are using a Windows server as this has been known to cause problems.
Also check your file permissions. Your website and all contents must generally be world-readable.
It is likely that your web server reported the source of the problem in its error log files. Please review these system error logs to determine what caused the problem. Often this will need to be resolved with your hosting provider or (if self-hosted) your web server configuration.
First check your file permissions. Your website and all contents must generally be world-readable.
Ensure that mod-rewite is installed and working, and that your .htaccess file
is being used. To verify the latter, create a file test.out containing the
word "test" in the top directory of Friendica, make it world readable and point
your web browser to
http://yoursitenamehere.com/test.out
This file should be blocked. You should get a permission denied message.
If you see the word "test" your Apache configuration is not allowing your
.htaccess file to be used (there are rules in this file to block access to any
file with .out at the end, as these are typically used for system logs).
Make certain the .htaccess file exists and is readable by everybody, then look
for the existence of "AllowOverride None" in the Apache server configuration for your site.
This will need to be changed to "AllowOverride All".
If you do not see the word "test", your .htaccess is working, but it is likely
that mod-rewrite is not installed in your web server or is not working.
On most Linux flavors:
% a2enmod rewrite
% /etc/init.d/apache2 restart
Consult your hosting provider, experts on your particular Linux distribution or (if Windows) the provider of your Apache server software if you need to change either of these and can not figure out how. There is a lot of help available on the web. Search "mod-rewrite" along with the name of your operating system distribution or Apache package (if using Windows).
Create an empty config/local.config.phpfile and apply world-write permission.
On Linux:
% touch config/local.config.php
% chmod 664 config/local.config.php
Retry the installation. As soon as the database has been created,
******* this is important *********
% chmod 644 config/local.config.php
Some configurations with "suhosin" security are configured without an ability to run external processes. Friendica requires this ability. Following are some notes provided by one of our members.
On my server I use the php protection system Suhosin [http://www.hardened-php.net/suhosin/]. One of the things it does is to block certain functions like proc_open, as configured in
/etc/php5/conf.d/suhosin.ini:suhosin.executor.func.blacklist = proc_open, ...For those sites like Friendica that really need these functions they can be enabled, e.g. in
/etc/apache2/sites-available/friendica:<Directory /var/www/friendica/> php_admin_value suhosin.executor.func.blacklist none php_admin_value suhosin.executor.eval.blacklist none
This enables every function for Friendica if accessed via browser, but not for the cronjob that is called via php command line. I attempted to enable it for cron by using something like:
*/10 * * * * cd /var/www/friendica/friendica/ && sudo -u www-data /usr/bin/php
-d suhosin.executor.func.blacklist=none
-d suhosin.executor.eval.blacklist=none -f bin/worker.phpThis worked well for simple test cases, but the friendica-cron still failed with a fatal error:
suhosin[22962]: ALERT - function within blacklist called: proc_open() (attacker 'REMOTE_ADDR not set', file '/var/www/friendica/friendica/boot.php', line 1341)
After a while I noticed, that
bin/worker.phpcalls further PHP script viaproc_open. These scripts themselves also useproc_openand fail, because they are NOT called with-d suhosin.executor.func.blacklist=none.So the simple solution is to put the correct parameters into
config/local.config.php:'config' => [ //Location of PHP command line processor 'php_path' => '/usr/bin/php -d suhosin.executor.func.blacklist=none
-d suhosin.executor.eval.blacklist=none', ],This is obvious as soon as you notice that the friendica-cron uses
proc_opento execute PHP scripts that also useproc_open, but it took me quite some time to find that out. I hope this saves some time for other people using suhosin with function blocklists.
If the setup fails to create all the database tables and/or manual creation from the command line fails, with this error:
ERROR 1067 (42000) at line XX: Invalid default value for 'created'
You need to adjust your my.cnf and add the following setting under the [mysqld] section:
sql_mode = '';
After that, restart mysql and try again.
Friendica is coded to always play nice. It checks whether the host machine is idle enough and if it seems to be overloaded, it intermittently refuses to process the worker queue.
Such checks originate from the days of single-user single-core machines and involves thresholds that you should adjust based on the number of exclusive CPU cores you have. See this issue for more information:
If you want to be neighborly and are using a shared web hosting PaaS provider, especially within the free tier, you need to set maxloadavg to say twice the maximum value of /proc/loadavg during peak hours.
If you have the whole (virtual) machine for yourself such as in case of an IaaS VPS, you can set it to orders of magnitude higher than its commonly observed value, such as 1000.
You should instead enact limits in your web server configuration based on the number of entry processes to cap the concurrent memory usage of your PHP processes.
See RLimitMEM, RLimitCPU, RLimitNPROC, StartServers, ServerLimit, MaxRequestsPerChild, pm.max_children, pm.start_servers and related options in your server.
You tried to upload an image up to 100kB and it failed.
You may not have the ownership or file mode set correctly if you are using the file system storage backend.
Change the backend to database. If this solves it, that is what needs to be fixed.
You may find 413 Request Entity Too Large or 500 Internal Error in the network inspector of the browser if the file is too large, for example if it is a video.
First try to upload a very small file, up to 100kB. If that succeeds, you will need to increase limits at multiple places, including on any web proxy that you are using.
In your PHP ini:
upload_max_filesize: defaults to 2MBpost_max_size: defaults to 8MB, must be greater thanupload_max_filesizememory_limit: defaults to 128MB, must be greater thanpost_max_size
You should verify whether you changed them in the right file by checking the web interface at the end of the overview on the Admin panel.
For Apache2:
LimitRequestBody: defaults to unlimitedSSLRenegBufferSize: defaults to 128kB, only if your site uses TLS and perhaps only when usingSSLVerifyClientorSSLVerifyDepth
For nginx:
client_max_body_size: defaults to 1MB
If you are using the database backend for storage, increase this in your SQL configuration:
max_allowed_packet: defaults to 32MB
If you use the ModSecurity WAF:
SecRequestBodyLimit: defaults to 12MBSecRequestBodyNoFilesLimit: defaults to 128kB, should not apply to Friendica
