Configuration settings of each virtual host are stored in its
configuration files in the/var/www/vhosts/system/ <domain_name> /conf/ directory.
Particularly, these files are the following:
- <version>
_httpd.conf– Apache virtual host configuration. - <version>
_nginx.conf– nginx configuration.
The final Apache configuration will include all httpd.conf andnginx.conf files from all virtual hosts.
Plesk lets administrators and domain owners see the history of changes
in a virtual host configuration files by saving each version of these
files. <version> here is a unique number assigned to a certain
configuration state that is used now or was used previously. To let
administrators and domain owners easily access the currently used
configuration file, Plesk stores the links last_httpd.conf andlast_nginx.conf that point to the corresponding files.
The system re-generates the configuration files after each change of
virtual host configuration, for example, changing the hosting type of a
domain. Therefore, if you edit httpd.conf and nginx.conf files
manually, your changes will be lost after changing the virtual host
settings in the Plesk UI. To avoid this, additional files are used to
specify custom configuration for domains:
vhost.confandvhost_ssl.conf– custom Apache directives for
two situations: when clients access the site over HTTP and HTTPS
respectively. These files are included in thehttpd.conf.vhost_nginx.conf– custom nginx directives. This file is included
in thenginx.conf.
The files with custom per-domain configuration are stored in the/var/www/vhosts/system/ <domain_name> /conf/ directory.
Most of the settings specified in these files override the server-wide
configuration of a virtual host (httpd.…
