Check if Apache is ON

[skinner]

Hi, I'm looking for a script to put on crontab that check if my domain is on, otherway it restart apache.

Sometimes my apache get freeze and I need to manually restart it.

I found many scripts that check if httpd is running, but in my case apache is working but none can connect to it.

How can I check if it's working and I can connect to my web pages?

My actually code is:

#!/bin/bash
    # Apache Process Monitor
    # Restart Apache Web Server When It Goes Down

    # RHEL / CentOS / Fedora http://en.wikipedia.org/wiki/Fedora  Linux restart command
    RESTART="/sbin/service httpd restart"

    # uncomment if you are using Debian / Ubuntu Linux
    #RESTART="/etc/init.d/apache2 restart"

    #path to pgrep command
    PGREP="/usr/bin/pgrep"

    # Httpd daemon name,
    # Under RHEL/CentOS/Fedora it is httpd
    # Under Debian 4.x it is apache2
    HTTPD="httpd"

    # find httpd pid
    $PGREP ${HTTPD}

    if [ $? -ne 0 ] # if apache not running
    then
     # restart apache
     $RESTART
    fi

Thanks...

Why is Apache freezing on your server? This seems more like a duct tape fix. I would consider seeing what is causing your apache to stop responding, so you can render this method obsolete..

You can use the script my friend coded here http://static.webden.org/

How can I check? In error log I don't see any specific error..

For example, I had just 1 hour downtime but it's gone online by itself.. I didn't restart apache..

Does your site stream or offer files for download?

No, only 1 blog and 1 forum...

What you describe sounds more like your server/cpu gets tied up on a process to the point where it cannot serve httpd processes; thus the temporary downtime/freeze.
