Dear All In an environment , I have 20 centos servers running together . For shutting them down , I need to issue the followings on each of the servers : #./stopServer #init 0 This is cumbersome to try to issue these on huge amount of servers to keep them safely going shutdown. Can you please let me know how can I automate it and say let just one server send stop processes and shutdown commands to the other ones and then goes shutdown himself? Thank you
A simple script which loops though a text file that lists the hostname / username / password for the login and then runs the "shutdown - h now" command? Though, I would be uneasy with listing root passwords in a random text file.

Thank you for your help. Is there any way to automate an ssh session on them say write a script to automatically ssh to them via root password and pass a command to them?
Please google for passwordless SSH authentication (Which many list members most likely will disapprove)
Request you to try something and post queries when it fails completely with error message etc.

Try out ansible.
Using it you can automate many more tasks distributed over your server environment through very simple configurations. It is very flexible and powerful.
