Gradual installation of debian packages

[Evgeniy Ginzburg]

Hello.
I'm assuming that you have paswordless ssh to the servers in question as
root.
Also I assume that you don't use central management/deployment software
(ansible/puppet/chef)
In similar cases I usully use parallel-ssh (gnu-parallel is another
alternative).
First stage install the package manually on one server to see that
configuration is OK, daemons restart, etc...
If this stage is ok second step will be creating list of servers for
"complain" list and install package on them trough parallel-ssh.
Instead of waiting for complains, one can define metrics to check and use
some monitoring appliance for verification.
I case of failure remove package from repository and remove-install again.
Third will be parallel-ssh install on all the servers.

P. S. In case of few tens of servers I'd prefer to work with ansible or
alternative, it's worh it in most cases/

Best Regards, Evgeniy.
