RE: [users@httpd] Suggestion for apachectl

[Axel-Stephane SMORGRAV <Ax...@europe.adp.com>]

You can certainly do something like what you propose in your apachectl, but you also probably want to avoid doing anything as clumsy as

        ps -ef | grep `cat /usr/apache/logs/httpd.pid` | grep -v grep > /dev/null 2>&1

Rather try something like
	kill -0 `cat /usr/apache/logs/httpd.pid`
	if [ $? ]; then ... fi
 
-ascs

Objet : [users@httpd] Suggestion for apachectl


We have setup to gracefully shutdown/startup of Apache via init.d
on our UNIX systems. Recently we had a power outage in our lab.
It caused httpd.pid file to remain in logs directory and prevented
Apache to automatically restart upon power up.
We had to manually remove httpd.pid in each machine and start Apache.
 
I am proposing following change in start section of apachectl
to automate startup in such condition.
Please comment. How can this be incorporated in Apache.

    if [ -r /usr/apache/logs/httpd.pid ]
    then
        # Check if apache is running
        ps -ef | grep `cat /usr/apache/logs/httpd.pid` | grep -v grep > /dev/null 2>&1
        if [ $? -ne 0 ]
        then
                # Probably system was not shutdown properly
                rm -f /usr/apache/logs/httpd.pid
        fi
