Hello Gurus,

I am desperately looking for all your helps. This is a most importane thing in my life.

I m in need of script which monitor services like apache,mysql,ftp etc and if its down it should restart and send an alert mail.

I am not great in bash script. But, i found the following. It works for a single service.

I just want a combination of this for many service. Some one, please help me.

Very big please.

#!/bin/bash

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



#!/bin/bash
if [ "$(ps aux | grep httpd | wc -l)" -lt "2" ]; then
echo "Mysql is Down" >&2
echo "Starting Mysql using customized script" >& 2
/etc/init.d/apache2 start
fi

Both the scripts work for one service. I need a single script which can monitor several services.

please help.......

You do realize you've mixed MySQL and Apache in the same file there??
Anyway, you could abstract the names of daemons out into eg a file and loop through reading that.
Ditto the restart cmds.
If you've got a lot of systems, maybe look at Nagios.
