CentOS

If I need to restart the httpd service in a production environment, what could happen? what is the best time window to do it?; thanks in advance

Umm, a graceful restart?

What could go work? Well config. errors (obviously!)

What is exactly a graceful re-start? thanks

Most of the time, its enough to reload apache and not restart it completely.

to reload

systemctl reload httpd

to restart

Code: Select all

systemctl restart httpd

if you use apache instances then you need to reload/restart those as well, for example:

systemctl reload httpd httpd@example.tld

Which version of CentOS are we talking about?

httpd restart
