Hi! I check the LiteSpeed extension in the Plesk panel, as a result of the tests I had a few questions: 1) When I switch LiteSpeed as the main server, Apache continues to work, and apparently Lightspeed is needed Apache to work. netstat shows that 80 and 443 ports listen by litespeed: Code: tcp 0 0 184.108.40.206:80 0.0.0.0:* LISTEN 389/litespeed (lsht tcp 0 0 220.127.116.11:443 0.0.0.0:* LISTEN 389/litespeed (lsht However, at the same time Apache is running, and if I try to disable Apache manually, then litespeed stops working: Code: lshttpd.service - LiteSpeed HTTP Server Loaded: loaded (/usr/lib/systemd/system/lshttpd.service; enabled; vendor preset: disabled) Drop-In: /usr/lib/systemd/system/httpd.service.d └─limit_nofile.conf Active: inactive (dead) since Tue 2018-07-24 16:58:17 MSK; 25s ago Process: 32049 ExecStop=/usr/local/lsws/bin/lswsctrl delay-stop (code=exited, status=0/SUCCESS) Process: 30896 ExecStart=/usr/local/lsws/bin/lswsctrl start (code=exited, status=0/SUCCESS) Main PID: 30917 Tasks: 0 Memory: 159.0M CGroup: /system.slice/lshttpd.service When restarts litespeed, Apache also restarts: Code: Jul 24 16:55:29 plesk-web systemd: Starting LiteSpeed HTTP Server...

I would like to completely abandon Apache, so that sites began to work exclusively through litespeed. Is it possible to do this on the LiteSpeed extension on Plesk Panel?
