When configuring Apache, some configuration options can be safely applied via a reload. Others require a full restart of the Apache process.
I have been unable to figure out which are which while reading the Apache docs. Nor have I found anything when searching the web.
So, which directives can be updated via a reload?
Which directives can only be updated via a restart?
See the directive quick reference for a list of all the directives.
Thanks for your help!
Edit: https://httpd.apache.org/docs/2.4/stopping.html doesn't list a reload. And I saw that the httpd.service file on CentOS 7 uses -k graceful for the reload command. Does that mean that a 'reload' on any OS is actually a graceful restart? Which would mean I could rely on a 'reload' to apply all my configuration changes safely.
