Replicating packages installation
 

Hi ,

My current setup have around 20 nodes and all it needs have some list package to be installed like Opencv
Octave 64 bit
Python
Numpy
Scipy
Openfst
Postgres
Sphere
Gnuplot
Boost
Atlas
Blas
vncserver
valgring and somemore ...

There are certain package in centos-6.3 by default but that are not higher version. I need latest release to be installed in all nodes. Is there any i can setup in one node and replicate all other nodes.? Most of them are tar files.
Please suggest if any that can best in centos-6.3

Thanks

I'm not sure if I understand correctly but if you are looking to setup some sort of configuration management then take a look at Puppet. It is a very in-depth and highly scalable solution.

If you just want to install a package onto twenty systems and its a tarball and this is a one-off, just rsync it to all of them and un-tar it.

If these are supposed to be Centos pkgs, using the yum cmd, then use ssh to run the cmd remotely like http://malcontentcomics.com/systemsb...s-via-ssh.html.
In your case, the remote cmd would start
You can loop the linked example to hit all 20 systems, using ssh auth keys ideally.
This will make it work without user interaction.
