Cron not sending mail

anaigini45 · 01-04-2010, 04:09 AM

I created a line in the same script that restarts mysql that will send email when the service is restarted.

The script is as follows :

Code:

#!/bin/bash
# MySQL Process Monitor
# Restart MySQL Web Server When It Goes Down
# -------------------------------------------------------------------------
# Copyright (c) 2003 nixCraft project <http://cyberciti.biz/fb/>

# RHEL / CentOS / Fedora Linux restart command
RESTART="/sbin/service mysqld 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 mysqld
# Under Debian 4.x it is mysqld
MYSQLD="mysqld"

SUBJECT="MySQL service status"

EMAIL="aigini@softsolvers.com.my"

EMAILMESSAGE="/tmp/emailmessage.txt"
 
# find mysqld pid
$PGREP ${MYSQLD}
 
if [ $? -ne 0 ] # if mysql not running
then
 # restart mysqld
 $RESTART
fi
#Email status too
echo $EMAILMESSAGE | /bin/mail -s "$SUBJECT" "$EMAIL"

But still I don't receive any mail....Pls help.

What does cron has to do with that?
Which mailing daemon do you use? postfix, sendmail, or anything else? If you don't use any, they please install postfix, this should fix your mail issue.

Is the email sent if you run the script manually instead of it being run by cron?

I've installed postfix in my Centos box, and this is what I run in the commandline :

Code:

#/sbin/script1.sh | /bin/mail -s 'Server status' aigini_2007@yahoo.com

The service is restarted, but I still do not get any email.

Please try to isolate the problem. Does using "/bin/mail" from the command line ever work? Have you looked in the postfix logs?

The default mailer daemon used in my server is sendmail.This is the output I get from :

Code:

tail -n100 -f /var/log/maillog.

Code:

I think /bin/mail does not work in the commandline..
