yum reinstall on cron not working

Question

I have a cron job the is run by the user called "taskmanager" every day and I need to reset a configuration every time.

the user taskmanager has NOPASSWD on /etc/sudoer

I also have a private repository where I made an RPM of my configuration. Whenever I ran the bash script manually the yum -y works flawlessly, however when the script is ran by cron the exit code is 1, manual execution's exit code returns 0.

    /usr/bin/sudo /usr/bin/yum -y reinstall --disablerepo="*" --enablerepo=codevault project-configuration
    echo $?

As which user runs your cronjob? root needs no sudo or is not allowed to use sudo. — Cyrus, Apr 02 '15 at 07:56
taskmanager user has root permission and has NOPASSWD. taskmanager is the one executing the cron — lloydm2, Apr 02 '15 at 08:30
okay sorry for the late comment. I found out that you cannot sudo on your cron. you need a tty for a sudo, unless you comment it out on /etc/sudoers :) thanks for the help guys — lloydm2, Apr 11 '15 at 18:41

Your cronjob doesn;t have the environment set up correctly - probably a missing environment variable.

Tasks run in cronjobs do not pick up the environment of the user, just the permissions. So your user has permission to run the command (your sudoers file is probably fine), but some environment variable required for the command to run correctly is not set.

To figure out what, look at the output of cron - you probably have mail. Once you've identified the missing variable, you can set it in your cron file in various ways
