Changing Paths to Services

Plesk uses various external components, for example, Apache web server, mail service, antivirus, and so on. When interacting with these components, Plesk gets the information on their locations from the configuration file /etc/psa/psa.conf.

Plesk configuration file provides an easy way of reconfiguring Plesk if a service is installed into another directory or migrated from the current partition to another. Note that you can only modify paths present in this file; other paths are hard-coded in Plesk components.

Each line of psa.conf has the following format:

<<strong class="placeholder">variable_name</strong>> <<strong class="placeholder">value</strong>>

A sample part of the psa.conf file is displayed below. To change a path to a service, utility, or package, specify the new path as a value of a corresponding variable.

# Plesk tree
PRODUCT_ROOT_D /usr/local/psa
# Directory of SysV-like Plesk initscripts
PRODUCT_RC_D /etc/init.d
# Directory for config files
PRODUCT_ETC_D /usr/local/psa/etc
# Directory for service utilities
PLESK_LIBEXEC_DIR /usr/lib/plesk-9.0
# Virtual hosts directory
HTTPD_VHOSTS_D /var/www/vhosts
# Apache configuration files directory
HTTPD_CONF_D /etc/httpd/conf
# Apache include files directory
HTTPD_INCLUDE_D /etc/httpd/conf.d
# Apache binary
HTTPD_BIN /usr/sbin/httpd
#Apache log files directory
HTTPD_LOG_D /var/log/httpd
#apache startup script
# Qmail directory
QMAIL_ROOT_D /var/qmail

Important: Be very careful when changing the contents of psa.conf. Mistakes in paths specified in this file may lead to Plesk malfunctioning.
