How To: Manage PHP Versions in NodeWorx

From the Webserver page in NodeWorx, Server Administrators have the ability to manage the PHP Mode for the system PHP version, install alternate PHP versions using the Multiple PHP tool, restart PHP-FPM and refresh the PHP-FPM cache.

Other PHP related tasks, such as upgrading the system PHP version and managing PHP config and ini files files must be completed via the CLI.

Information on allowing SiteWorx accounts access to specific PHP versions can be found here.

Documentation on how to set PHP versions for specific domains in SiteWorx can be found here.

To Change the PHP Mode for the System PHP Version

Note

The versions of PHP provided by the Multiple PHP tool within InterWorx use PHP-FPM by default, whether the system-level PHP mode is set to SuPHP or PHP-FPM.

1. Log into NodeWorx from the browser (https://ip.ad.dr.ess:2443/nodeworx)

2. From NodeWorx, navigate to System Services > Web Server > Overview

   

3. Under PHP Integration Mode, select the desired PHP Mode from the PHP Mode dropdown. There are two options:

   

   • mod_suPHP: Apache module that runs PHP scripts as the script owner, using the script owner’s permissions

     • If a user’s script is compromised, it will not affect other users

     • Can prevent users from running unauthorized PHP scripts, as they will not have the proper permissions to do so

   • PHP-FPM: Process manager that runs PHP scripts as a separate process outside of the web server, and communicates with the web server using FastCGI

     • Better able to handle large numbers of concurrent requests

     • Generally better performance and scalability vs suPHP

     • Better resource management than suPHP

4. Click Update
