Enabling Per-User php.ini

This document lists the options for enabling a per-user php.ini when you are not running CloudLinux. For CloudLinux and CL PHP Selector has been used, you should refer to "substitute global php.ini for individual customer".

The following steps show you how to do it when you are running off LSWS-native configs or running LiteSpeed Web Server (LSWS) off of Apache configurations.

Defining the PHPRC environment variable in the WebAdmin console allows you to use a variable that can set a standard location for the php.ini file in each virtual host.

In your external application Environment setting (WebAdmin console > Server > External App > lsphp5), enter: PHPRC=variable/php.ini/directory

Example:

PHPRC=$VH_ROOT/public_html

The variables available for use are:

1. $VH_ROOT: the virtual host's home directory
2. $VH_NAME: the virtual host's domain
3. $VH_USER: the virtual host's user

Note:

• Using this method will cause LSWS to ignore any global php.ini files and only use the user-defined php.ini.

Defining the PHPRC environment variable in Apache's virtual host configurations allows you to set a php.ini location for a specific virtual host.

In the Apache virtual host configuration file, add SetEnv PHPRC /php.ini/directory.

Note:

• Using this method will cause LSWS to ignore any global php.ini files and only use the user-defined php.ini.
• This method is supported in LSWS 4.2.13 and up.

Using the PHP_INI_SCAN_DIR environment variable allows you to use a variable that can set a standard location for the php.ini file in each virtual host. Unlike the PHPRC environment variable, though, PHP_INI_SCAN_DIR allows the use of the global php.ini file with the addition of a per-user php.ini.

In your external application Environment setting (WebAdmin console > Server > External App > lsphp5), enter: PHP_INI_SCAN_DIR=variable/php.ini/directory

Example:

PHP_INI_SCAN_DIR=$VH_ROOT/public_html

The variables available for use are:

1. $VH_ROOT: the virtual host's home directory
2. $VH_NAME: the virtual host's domain
3. $VH_USER: the virtual host's user

Note:

• This method is not recommended if you replace Apache with suPHP. When replacing Apache with suPHP, the PHPRC environment variable is recommended.
• The PHP_INI_SCAN_DIR environment variable is available for PHP 5.2.7 and up.

Using the PHPIniDir directive in Apache's virtual host configurations allows you to set a php.ini location for the main virtual host of a specific user.

In the Apache virtual host configuration file, add PHPIniDir /path/to/php.ini/directory

Note:

• The PHPIniDir directive at the vhost level has been supported since LSWS 4.0.2.
• The PHPIniDir directive is effective ONLY IF placed in the 1st (or main domain) vhost of the user. Placing this directive in a subdomain vhost will be cause it to be ignored.

• PHP suEXEC MUST BE ENABLED IN LSWS.
• Make sure the php.ini file is readable by the suEXEC user.
• Option 3 can be used along with options 1, 2, or 4 without conflicts. However, this should rarely be needed.
• Option 4 takes precedence over options 1 and 2 should they be used at the same time.
• Changes in the php.ini will not be picked up until new PHP process starts. The php.ini is read for the first time when a PHP process starts.
• Per-user php.ini files are not compatible with suEXEC Daemon mode. Our two other PHP suEXEC setups both support per-user php.ini.
