Apache's init script needs a small addition to allow it to perform graceful
restarts--graceful restarts do zero-downtime updates of loaded modules and
configuration file alterations.  This is very handy for people using Apache
on mission-critical servers.

The URL I listed explains exactly what how graceful restarts work.

Here's what I added to the /etc/rc.d/init.d/httpd init script:

        echo -n "Hot starting httpd: "
        killproc httpd -USR1

"graceful" might be a better name for the target than "hotstart".  Also, it
would make a lot of sense to store the killproc return value and exit from
the init script with that return value.  That would turn the above into:

        echo -n "Gracefully restarting httpd: "
        killproc httpd -USR1
        exit $RV

And the default line ("Usage: $0 {.....}") should probably mention the
graceful/hotstart option.

This should be incorporated into apache-1.3.12-10, which will hit Raw Hide soon.

Comment 2 Matthew Miller 2001-09-04 23:13:29 UTC
actually, this isn't in the very latest rawhide (apache-1.3.20-15). Looks from
the comments like it was added at one point, but now it's gone again.

The apachectl script that comes with apache also has a "configtest" option,
which would be nice.

Comment 5 Joe Orton 2002-05-27 11:56:30 UTC
The apache packages do now support "service httpd configtest".
