Quote:

#!/bin/sh

wget website.com -o /tmp/web
value=`cat /tmp/web |grep OK | nl|awk '{print$1}'`

if [ $value -eq '' ]
then

restart service
fi

but I know there are better ways to do that

whats your way?

Thanks

Code:

#!/bin/sh
# Apache Process Monitor
pgrep httpd
if [ $? -eq 0 ]
then
 # restart apache
 service httpd restart
fi

Save script monitorhttpd.sh. Next set cronjob

Code:

 */5 * * * * sh /path/to/monitorhttpd.sh >/dev/null 2>&1

I like yours more than mine, .. still i'll paste it here for global interest.

Quote:

#!/bin/sh

URL=site.es

lynx -dump "$URL" > /dev/null 2> /dev/null

EXITCODE=$?

if [ "$EXITCODE" -eq "0" ]
then
echo "OK"
else
# echo "ERROR: $EXITCODE"
/opt/www/site.es/bin/zopectl restart
fi

exit 0
