How to execute command on a custom group of servers? or how do i create a list of servers where i would like to execute my command in parallel?
Mexec List feature lets you create your own custom grouping of servers and then run your commands using Parallel Shell on it.
- Create your custom group using the mExec lists feature.
2. Select server into the custom group 'my-kernel-update-list'
Note: For a regular user to access the mExec list, make sure to grant privilege on the parallel shell and view mExec list.
Click on the Access control >> user action >> select user, give privilege on the parallel shell and view mExec list.
You can add a server in more than one mExec lists groups. ie, server 1 can be in mExec lists group 1 and group 2.
3. Login to the ssh backend interface and navigate to the multi-server menu and you would see the group 'my-kernel-update-list'. Hit enter
4. Enter the command uptime in the command line to get it executed across the server in the group 'my kernel update list'
