Dies ist die orginal Friendica Installations Anleitung, auch zu finden auf GitHub

Friendica Installation

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. 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.

Before you begin: Choose a domain name or subdomain name for your server. Put some thought into this - because changing it is currently not-supported. Things will break, and some of your friends may have difficulty communicating with you. We plan to address this limitation in a future release. Also decide if you wish to connect with members of the Diaspora network, as this will impact the installation requirements.

Decide if you will use SSL and obtain an SSL cert. Communications with the Diaspora network MAY require both SSL AND an SSL cert signed by a CA which is recognised by the major browsers. Friendica will work with self-signed certs but Diaspora communication may not. For best results, install your cert PRIOR to installing Friendika and when visiting your site for the initial installation in step 5, please use the https: link. (Use the http: or non-SSL link if your cert is self-signed).

1. Requirements

  • Apache with mod-rewrite enabled and „Options All“ so you can use a local .htaccess file
  • PHP 5.2+. The later the better. PHP 5.3 is required for communications with the Diaspora network and improved security.
  • PHP *command line* access with register_argc_argv set to true in the php.ini file [or see 'poormancron' in section 8]
  • curl, gd (with at least jpeg support), mysql, mbstring, mcrypt, and openssl extensions
  • some form of email server or email gateway such that PHP mail() works
  • Mysql 5.x
  • ability to schedule jobs with cron (Linux/Mac) or Scheduled Tasks (Windows) [Note: other options are presented in Section 8 of this document]
  • Installation into a top-level domain or sub-domain (without a directory/path component in the URL) is preferred. This is REQUIRED if you wish to communicate with the Diaspora network.

2. 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 - as „dot“ files are often hidden and aren't normally copied.

3. Create an empty database and note the access details (hostname, username, password, database name).

4. If you know in advance that it will be impossible for the web server to write or create files in your web directory, create an empty file called

.htconfig.php

and make it writable by the web server.

5. Visit your website with a web browser and follow the instructions. Please note any error messages and correct these before continuing. If you are using SSL with a known signature authority (recommended), use the https: link to your website. If you are using a self-signed cert or no cert, use the http: link.

6. If the automated installation fails for any reason, check the following:

  • „.htconfig.php“ exists. → If not, edit htconfig.php and change system settings. Rename to .htconfig.php
  • Database is populated. → If not, import the contents of „database.sql“ with phpmyadmin or mysql command line

7. 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 .htconfig.php to another name and empty (called 'dropping') the database tables, so that you can start fresh.

THIS NEXT STEP IS IMPORTANT!!!!

8. Set up a cron job or scheduled task to run the poller once every 5-10 minutes to pick up the recent „public“ postings of your friends. Example:

cd /base/directory; /path/to/php include/poller.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 include/poller.php

You can generally find the location of PHP by executing „which php“. If you have troubles with this section please contact your hosting provider for assistance. Friendica will not work correctly if you cannot perform this step.

Alternative: You may be able to use the 'poormancron' plugin to perform this step if you are using a recent Friendica release. 'poormancron' may result in perfomance and memory issues and is only suitable for small sites with one or two users and a handful of contacts. To do this, edit the file „.htconfig.php“ and look for a line describing your plugins. On a fresh installation, it will look like

$a->config['system']['addon'] = 'js_upload';

This indicates the „js_upload“ addon module is enabled. You may add additional addons/plugins using this same line in the configuration file. Change it to read

$a->config['system']['addon'] = 'js_upload,poormancron';

and save your changes.

If things don't work…

  • If you get the message
"System is currently unavailable. Please try again later"

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“.

  • 500 Internal Error

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.

  • 400 and 4xx „File not found“ errors

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 flavour of Linux,

% 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. Google „mod-rewrite“ along with the name of your operating system distribution or Apache package (if using Windows).

* If you are unable to write the file .htconfig.php during installation due to permissions issues: create an empty file with that name and give it world-write permission.

For Linux:

% touch .htconfig.php
% chmod 777 .htconfig.php

Retry the installation. As soon as the database has been created,

this is important

% chmod 755 .htconfig.php
