Installation

Prerequisites

Before installing X2EngineCRM, you should first ascertain whether your hosting environment is properly configured. The following features are *required* for X2EngineCRM to function properly:

• PHP version 5.3 or later
• cURL library
• A password-protected MySQL database server connection, and a database on which the user of the connection has all rights (i.e. select, drop, create and update).
• The 2 web server, with [1] enabled.

Next, ensure that the requirements of "Yii Framework", the application building framework on which X2Engine is designed, are met. To do this:[list=1]

• Download the "yii-requirements" file attached to this post, and upload/unpack it into your web server.
• Navigate to the yii-requirements folder on your web server. You should see a page that looks similar to this:

[sharedmedia=core:attachments:13]

• Note that the following requirements are not necessary:

- The SQLite and PostgreSQL extensions; X2Engine depends on MySQL, so these other extensions will not be used. - The DOM extension; it is not required. - The caching extensions (Memcache, APC cache); caching is not currently required, although APC can increase performance - The SOAP extension; the classes that depend on it are not used

Note to users of CentOS Linux, esp. release version 6:[/b] two additional PHP packages that are non-default (but very common, and almost ubiquitous) and not installed by default with the CentOS's base php package are [i]php-mbstring[/i] and the [i]mcrypt[/i] module[i]. [/i]In a shared hosting environment, these will most likely be installed already. However, if you plan on setting up your own server and using CentOS, you must install mbstring package by running [b][color=#006400]yum install php-mbstring[/color][/b] as root and restarting Apache (i.e. [b][color=#006400]sudo service httpd restart[/color][/b]). To install mcrypt, the recommended method is to first the EPEL repository (php's mcrypt is unavailable in the default repositories). Then, it can be installed via running [b][color=#006400]yum install php-mcrypt[/color][/b] as root.
