CentOS - Nov 2015 - use pssh to restart a service

Hey Gordon,

 Sorry, man my bad! Disabling the tty requirement for my sudo user does
indeed work. I had a type-o in the sudoers file, and when I corrected it,
my sudo command via pssh started working!

#pssh -i -h es_list "/bin/sudo  /bin/systemctl restart elasticsearch; sleep
10"
[1] 20:31:32 [SUCCESS] bluethundr at es3.jokefire.com
Stderr: sudo: sorry, you must have a tty to run sudo
[2] 20:31:32 [SUCCESS] bluethundr at es2.jokefire.com
[3] 20:31:32 [SUCCESS] bluethundr at es1.jokefire.com

I'm still getting the 'sorry you must have a tty to run sudo'
message
coming from one of the nodes. But the command succeeds so it's no big deal!
Odd tho that one node would be barking about that, considering my
sudoers is distributed via puppet.

Anyway, it's all good as far as I'm concerned. At least this works!
I'll
check that 3rd node and see if there's any difference to the sudoers file I
guess.

Thanks for your help!

This is why it is paramount to use visudo command as opposed editing the
/etc/sudoers file directly!  The visudo command will check the edited temporary
sudoers file syntax before committing to /etc!

Ok! Makes sense! I'll make sure I do that from now on!

Thanks!!
