-====== Troubleshooting LiteSpeed Web Server with cPanel/WHM ====== 
  
-This wiki will address problems that may occur on a LiteSpeed Web Server/WHM installation. The installation process is covered in our [[litespeed_wiki:​cpanel:​auto-installer|Auto-Installer wiki]]. 
- 
-**Note:** For free support of LSWS please use the [[http://​www.litespeedtech.com/​support/​forum/​|LiteSpeed forum]]. If you have an issue with cPanel (even while using LSWS) please contact cPanel support. They are fully trained to handle LiteSpeed Web Server. 
- 
-===== Insufficient Process Memory ===== 
- 
-Insufficient process memory may result in the following error messages (when you try to build matching PHP): 
- 
-<​file>​ 
-Found Errors 
- 
-ERROR: /​usr/​local/​bin/​php -i returns 6  
- 
-You can try to build matching PHP from command line:  
-"/​usr/​local/​cpanel/​whostmgr/​cgi/​lsws/​cmd_buildmatchingphp.sh"​ 
-</​file>​ 
- 
-or 
- 
-<​file>​ 
-Found Errors 
- 
-ERROR: /​usr/​local/​bin/​php -i returns 134 
- 
-You can try to build matching PHP from command line:  
-"/​usr/​local/​cpanel/​whostmgr/​cgi/​lsws/​cmd_buildmatchingphp.sh"​ 
-</​file>​ 
- 
-To fix this, try increasing the "Max cPanel process memory (Minimum: 512)" in WHM > Server Configuration > Tweak Settings. 
- 
-===== LiteSpeed Does Not Restart When Configuration Changes ===== 
- 
-In order for configuration changes to take effect, LiteSpeed Web Server should restart automatically. Do **NOT** uncheck the "​httpd"​ service under WHM > Service Configuration > Service Manager. If unchecked, WHM will not restart LiteSpeed automatically when configurations have been changed. 
- 
-===== Incorrect gcc Permissions ===== 
- 
-cPanel may set permissions for /​usr/​bin/​gcc to 0700. This will break our PHP build script. To fix this, change the permissions for the directory: ​ 
- 
-  chmod 0755 /​usr/​bin/​gcc 
- 
-After finishing your PHP build, you can change permissions back: 
- 
-  chmod 0700 /​usr/​bin/​gcc 
- 
-===== mod_ruid2 Incompatibility ===== 
- 
-LSWS is not compatible with mod_ruid2 because LSWS does not the process user to change mid-process. Make sure that mod_ruid2 is disabled in your WHM settings when using LSWS. LSWS is compatible with Apache prefork or event MPM. 
- 
-If mod_ruid2 is enabled, a variety of functionality may be disrupted due to WHM creating files that the web server user cannot access.
