Question

How to enable Apache graceful restart in Plesk?

Answer

By default, Plesk does not use Apache graceful restart for applying new settings. As a result Apache will be restarted every time you change hosting settings through the Plesk GUI.

Note : that enabling graceful restart can lead to an unwanted websites downtime.

In order to enable graceful restart, add restart_apache_gracefully parameter with a true value to the psa.misc table:

1. Log in to the Plesk database:

   # MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql -u admin psa
   

2. Apply the following MySQL query:

   mysql> INSERT INTO misc VALUES ('restart_apache_gracefully', 'true');
