I usually just do something like the following:

for i in $SERVER1 $SERVER2 $SERVER3; do
scp myTasks.sh root@$i:/tmp
ssh root@$i '/bin/bash /tmp/myTasks.sh ; [[ $? != 0 ]] && echo "stuff broke" || rm -f /tmp/myTasks.sh'
done

A good alternative

Anonymous's picture

I've started using 'Salt' for this purpose. It handles all the rsa key authentication automatically, allows for remote execution of scripts, and also, offers a higher level configuration management system.

Perl alternative

Anonymous's picture

There is a similar Perl alternative around, which I prefer for such tasks, as the Perl syntax is just simpler. It's called (R)?ex or just "Rex".

Nice, thanks for the tip.

I wrote something along these lines some time ago, but packaged it as a turnkey utility:

pssh!

Been using pssh for quite a while to do just this!

And since I'm using Bash to execute items, I can combine it with any arbitrary Bash code to make robust, complex, elegant applications for deployment or administration tasks. :)

Better tool available

Anonymous's picture

I have found CSSH (Cluster SSH) to do this task quite well. Plus it sounds a lot more simple to use.

Hello there.

I believe that almost every linux admin has done something like that tool-set on his/hers career. Either with python, ruby, or (k,z,c,ba,)sh script...

But what I find good about this is that it's not being kept closed in a "box". :)

Good job, and thank you for doing this.

Rgds,

Webinar
Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
