When you change a website’s hosting settings, the changes
take effect only after the Apache restart.
You can choose between the Apache normal and graceful restart.
The normal restart immediately kills all Apache processes, which leads to
a short downtime for all websites hosted on the server.
The graceful restart instructs Apache to gradually replace the existing
processes with new ones. This does not affect the websites and
no downtime occurs.
To avoid downtime, Apache in Plesk uses the graceful restart by default.
If the graceful restart does not work as expected, you can choose
the Apache normal restart.
To choose the Apache normal restart:
- Go to Tools & Settings > Apache Web Server (under “General Settings”).
- Clear the “Apache graceful restart” checkbox and then click OK.
