[arch-general] Server Management Tools
Hello, Is there a way to automatically administer multiple arch Linux servers? It's annoying to provide 20 servers daily with the same commands. Are there possibilities to manage the daily tasks centrally and to set them off automatically? I know there are tools like puppets but they're too cluttered. Thank you for help. Silvio

cron + pssh?

Sounds good okay cron I not need but pssh sounds great. But at end I become only siefke@sisibox ~ $ pssh -h .config/pssh-hosts -P yaourt -Suy [1] 20:03:54 [FAILURE] host1 Exited with error code 255 [2] 20:03:55 [FAILURE] host2 Exited with error code 255 [3] 20:03:55 [FAILURE] host3 Exited with error code 255 [4] 20:03:56 [FAILURE] host4 Exited with error code 255 Work it with SSH Keys and sudo?

We use ansible to manage arch's servers: https://git.archlinux.org/infrastructure.git Ansible can be automated using pull, but there are other options as well. Regards, Giancarlo Razzolini

Yes I was thinking for it but for yaourt -Suy is for me little overloaded. But ok I will try it with the time. Thanks for link sure will help me. Silvio

If I knew that you wanted to automate yaourt, I would not even replied to you in the first place. You seriously consider unattended update of packages on servers a good practice? On Arch? Good luck with that. Regards, Giancarlo Razzolini

Who say something from unattended? I want not only set 20 times the same command. That's all. On the arch server run nothing special. Mail, Web, DNS and VPN and nothing on one alone. Silvio

And writing a bash script that ssh's in and does everything is sooo difficult? If you can't do it, don't update machines automatically. -- Leonid Isaev

Look into clusterssh then. You'll get the output of all commands on all servers and can interact with a only a single one, in case there are unexpected errors. Other than that orchestration is great (Ansible, Puppet, etc.), although it takes more knowledge and experience. Best regards, Karol Babioch

Indeed, this is the most terrifying of messages to ever appear. You just ran a command across N machines, two of them failed. Ugh. The *BEST* case is things like e.g. "apt-get update" failing because of a spurious mirror resolution failure. (Or maybe the UDP DHCP query failed for one or two or three of your hosts?.)

Choose this path. (I have no idea of what's best, but almost *anything* is better than "iterate through hosts and run command".) Regards,
Well, First you have shellscript, based on ssh client and gnu parallel. Second you can write your own python script with paramiko and parallel library Third you can look to fabric (http://www.fabfile.org/) Fourth, you can easely learn Ansible, which tends to become the #1 server management tool under the strong marketing effort from Redhat. More and more big company are leaving puppet and using Ansible, and now they even opensourced Tower (look at awx) 2017-10-13 21:44 GMT+02:00 Bardur Arantsson <spam@scientician.net>:
