Restarting a service

Some maintenance procedures require you to stop a single service while keeping other services on the grid node running. After you have completed tasks that required you to stop a service, restart that service.

1. From the service laptop, log in to the grid node:
   1. Enter the following command: ssh admin@grid_node_IP
   2. Enter the password listed in the Passwords.txt file.
   3. Enter the following command to switch to root: su -
   4. Enter the password listed in the Passwords.txt file.
   When you are logged in as root, the prompt changes from $ to #.
2. Restart a manually stopped service: /etc/init.d/service start
   For example,

   /etc/init.d/ldr start

3. Restart a running service: /etc/init.d/service restart
4. Log out of the command shell: exit
