Comment 5 for bug 2054301

Hi Sergio,

do you really mean "systemctl restart apache2"? Because this will disrupt service and stop the whole webserver and then start it again.

I guess you meant "systemctl reload apache2".

The issue is the same, since they all do the same:

logrotate calls "invoke-rc.d apache2 reload" which calls "/etc/init.d/apache2 reload" which calls "apache2ctl graceful":

% grep -A 6 -F 'do_reload()' /etc/init.d/apache2
do_reload() {
 if apache_conftest; then
         if ! pidofproc -p $PIDFILE "$DAEMON" > /dev/null 2>&1 ; then
                 APACHE2_INIT_MESSAGE="Apache2 is not running"
                 return 2
         fi
         $APACHE2CTL graceful > /dev/null 2>&1
-----------------------------------------------------------------

systemd does the same:

% cat /lib/systemd/system/apache2.service
...
[Service]
---
ExecStart=/usr/sbin/apachectl start
ExecStop=/usr/sbin/apachectl graceful-stop
ExecReload=/usr/sbin/apachectl graceful
-----------------------------------------------------------------

So it doesn't matter. You can even send SIGUSR1 to the apache2 father process which does the same:

AH00493: SIGUSR1 received. Doing graceful restart
