Question

Where web server configuration files for the domain example.com are located in Plesk for Linux?

Answer

The web server configuration files for the domain are located inside /var/www/vhosts/system/<domain_name>/conf/ directory, for example:

# ls -l /var/www/vhosts/system/example.com/conf/
ttotal 56
-rw------- 1 root apache 7992 Mar 21 12:43 httpd.conf
-rw------- 1 root apache 7992 Mar 21 12:43 httpd.conf.bak
lrwxrwxrwx 1 root root 10 Mar 21 12:43 last_httpd.conf -> httpd.conf
lrwxrwxrwx 1 root root 10 Mar 21 12:42 last_nginx.conf -> nginx.conf
-rw------- 1 root nginx 4285 Mar 21 12:42 nginx.conf
-rw------- 1 root nginx 4285 Mar 21 12:42 nginx.conf.bak
-rw-r--r-- 1 root root 24132 Mar 19 13:16 webalizer.conf

Note: in case the domain example.com is set as Default Site in Plesk > Tools & Settings > IP addresses > 192.0.2.2, the main configuration files of the domain are named as httpd_ip_default.conf and nginx_ip_default.conf.
