How to Install package in 15 Server at a time.
 

Hi Friends,

Nearly I had an interview with wipro technologies.

The interviewer asked one question about packages installation.

He has a package for Redhad server and he want to install this packages with in 15-20 server at a time.

So,How can we install this package with out going in front of the the server and need to install this package at a time on 15-20 system.


Friends,If you know answer kindly share with me.

Well there are many ways,

1.If yum repo is enabled on all machines, simply copy your rpm in repo and call yum install <your rpm name> on each machine through ssh.
2.Copy .rpm file on each machine through SSH and execute rpm -ivh remotely.

Make use of an automated deployment solution like Puppet to make future deployments easier.

If you have the correct host keys set up securely you could use any one of a number of distributed ssh scripts to issue one command to all the servers (there's also the classic "SSH in a for loop solution" ;-)). However, I second the use of Puppet or something similar for configuration management. There are also tools like Spacewalk that can push packages to remote machines from a central console.

And traditional answer missing: Call to Redhad service, they will sell you RHN satellite.

Depends on the package I suppose. Are you building it from source? Are you instaling it from redhad repos? Is it an update? Is it oart of regular maintenance or a one time specific install? Puppet seems overkill for one package install.
