sudo: sorry, you must have a tty to run sudo

My e1agent start script is not running on reboot, but it is when I run the service command manually…  What is going on?

This is easy, if you look into your /u01/oracle/jde_home_1/SCFHA/logs/e1agent_0.log file (equivilent), you might get the text below:

sudo: sorry, you must have a tty to run sudo

Great, this is super simple.

All you need to do is vi /etc/sudoers and

#
# Disable "ssh hostname sudo <cmd>", because it will show the password in clear.
#         You have to run "ssh -t hostname sudo <cmd>".
#
#Defaults    requiretty

Comment out the above, now you’ll be cooking with gas.
