| + | To enable SuEXEC for LSWS native or on OpenLiteSpeed, you will need to create external apps (name should be unique and different than server level external apps and other virtual host external apps, for example, lsphp_$vhost; also set it to run as username:usergroup to implement PHP SuEXEC) and script handler pointing to the newly created external app under each virtual host. | ||

| - | Process Group Mode is similar to Apache php-fpm mode. The difference is: with Apache, the parent process of php-fpm is not controlled by Apache, and it keeps running; with LiteSpeed, LiteSpeed uses LSAPI, and the PHP will exit if idle for a while (in a shared hosting environment). For LSWS 5.2.8 and lower versions, PHP processes will stop when LSWS restarts, and the opcode cache will be reset. Starting from LSWS 5.3RC2 and above, LSPHP will run in detached mode and an LSWS restart //won't// stop PHP processes. The LSPHP parent will just follow the timeout where [[https://www.litespeedtech.com/docs/webserver/config/extapps/lsapi#extMaxIdleTime|"Max Idle time"]] is set. | + | Process Group Mode is similar to Apache php-fpm mode.
