# 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 recognized by major browsers.

Friendica will work with self-signed certs but Diaspora communication may not.

For best results, install your cert PRIOR to installing Friendica and when visiting your site for the initial installation in step 5, please use the https: link.

## 1. Requirements
|
||||
|
||||
- Apache with mod-rewrite enabled and "Options All" so you can use a local .htaccess file
|
||||
- PHP 5.6.1+ (PHP 7 recommended for performance).
|
||||
- PHP *command line* access with register_argc_argv set to true in the php.ini file [or see 'poormancron' in section 8]
|
||||
- PHP *command line* with `register_argc_argv = true` in php.ini
|
||||
- curl, gd (with at least jpeg support), mysql, mbstring, xml, zip and openssl extensions
|
||||
- Some form of email server or email gateway such that PHP mail() works
|
||||
- The POSIX module of PHP needs to be activated (e.g. RHEL, CentOS have disabled it)
|
||||
- Composer for a Git install
|
||||
|
||||
- Mysql 5.5.3+ or an equivalant alternative for MySQL (MariaDB, Percona Server etc.)
|
||||
- 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.
|
||||
- For alternative server configurations (such as Nginx server and MariaDB database engine), refer to the [Friendica wiki](https://github.com/friendica/friendica/wiki).
