Linode default CentOS 6.5 64bit deployment does not include Crontab or Cron Job. Here is a reference for the people like me.

Install the package and dependencies

#yum install vixie-cron

Enable the package on boot and start

# /sbin/chkconfig crond on
# /etc/init.d/crond start

crontab command option:

crontab: usage error: unrecognized option
usage:  crontab [-u user] file
crontab [-u user] [ -e | -l | -r ]
(default operation is replace, per 1003.2)
-e      (edit user’s crontab)
-l      (list user’s crontab)
-r      (delete user’s crontab)
-i      (prompt before deleting user’s crontab)
-s      (selinux context)

Stop cron emails at Dreamhost

I have some site on the Dreamhost. To monitor the traffic and performance, I have Awstats on site and runing many cron jobs every day. I have the experience of how to install AwStats on the Ubuntu server.
The cron job is runing well on the Dreamhost server. The problem is I will receive tons of email about the job status.
Actually, I don’t need these emails. If the job is completed successfully, the Awstats report should be updated. I checked the report often. So the fail of job is not my concern.
To disable cron emails, just add one line code as shown below:
First SSH server.

$ crontab -e

add this line to the top of your cron file:

MAILTO=””

That’s simple. No more cron emails coming.
