how to restart apache automatic .

how to restart apache automatic every 12 hours ?

 

any solution please ?

 

You could set up a Cronjob like so:

0 0,12 * * * /etc/init.d/httpd restart

 

Better make gracefull restart. Apache will wait till conection finishes and close it, then restart (when all connections will be closed). Otherwise it will terminate all connections.

To make graceful restart - edit your /etc/crontab and add this line:

 

@Deltahost,

graceful and restart are grouped in the same case statement in the Apache init.d script, so either will work.

case $ARGV in
start|stop|restart|graceful|graceful-stop)
    $HTTPD -k $ARGV -DSSL
    ERROR=$?
    ;;

Code (markup):

 

The same case, but ARGV passed to httpd binary is different And behavior of httpd will be different
