• Allows you to set a specific WebServer for a particular website.

• After enabling Multi-WebServer Hosting, when using the Add WordPress function in WP Toolkit, the combination of Nginx + Openlitespeed is adopted by default to provide faster access speed.

Automatic Operations of Multi-WebServer Hosting

• Automatically installs three WebServers: Nginx, Apache, and Openlitespeed.

• After the installation is completed, aaPanel will automatically detect and resolve port conflict issues.

  	Apache	80/443	Complex PHP applications (Magento), applications dependent on Apache modules
  	Openlitespeed	80/443	WordPress
  Multi-WebServer	Nginx (Proxy) -> Apache	Nginx: 80/443 Apache: 8288, 8290	Complex PHP applications (Magento), applications dependent on Apache modules
  	Nginx (Proxy) -> Openlitespeed	Nginx: 80/443 Openlitespeed: 8188	WordPress

PHP Management for Multi-WebServer

Nginx/Apache PHP Management

• The PHP used by Nginx/Apache, e.g., for php83: /www/server/php/83/bin/php

• Configure and manage PHP (such as modifying configurations, installing extensions, etc.) through the PHP-8.3 management interface in the App Store.

Openlitespeed PHP Management

• The default PHP used by Openlitespeed is lsphp; for example php83: /usr/local/lsws/lsphp83/bin/php

• Configure and manage PHP (lsphp) (such as modifying configurations, installing extensions, etc.) through the Openlitespeed management interface in the App Store.

• PHP extensions for Openlitespeed can also be installed using the apt/yum commands. For the list of supported PHP extensions, please visit: http://rpms.litespeedtech.com/

Notes

1. Failure to Enable Multi-WebServer Hosting

   • Please check if the configurations of Nginx/Apache/Openlitespeed are normal.

   • If enabling Multi-WebServer Hosting fails, the installed services will be automatically uninstalled.

   • Please check the installation log to see if there is a failure in installing Nginx/Apache/Openlitespeed. Error log file: /tmp/panelExec.log (It is normal to see a prompt indicating port conflicts under regular circumstances).

   • The panel log records the reasons for the startup failure of Nginx/Apache/Openlitespeed. Please view the log via: Logs --> Panel Logs --> Operation Logs

   • Are other ports (excluding ports 80, 443, 887, and 888) being used repeatedly?

   • If after turning on Multi-WebServer Hosting, one of the services fails to start, you can try to click Repair to repair it.

2. Modifying the Running Service of Site

   • When modifying the Web Server currently used by a site, it is recommended to back up the site configuration file first to avoid configuration loss or errors during the modification process.

   • If the identifier in the site configuration (starting with #) has been manually deleted, do not modify the Web Server.

   • After the modification is completed, be sure to check whether the website can be accessed normally.

3. Using a Single WebServer (Nginx/Apache/Openlitespeed)

   • First, disable the Multi-WebServer Hosting function, then select the single service (Nginx, Apache, or Openlitespeed) you want to keep.

4. After changing the Web Server, please check whether the website is running normally.

Performance testing

Test environment configuration

• System: Debian 12
• Website type: Wordpress
• PHP version: PHP 8.2

Test results

• PS: The test environment is based on the default Settings created by the aapanel panel and excludes network latency factors.

• Note: Each item will be tested three times respectively, and the average of the test results will be taken.

• In concurrent scenarios, caching is a key influencing factor for the performance of Web servers. Multi-WebServer Hosting has added support for apache cache, enabling it to better handle concurrent scenarios.
