Add packages if needed, please keep the comment I have +added about who requested what and why, if not obvious ( first one to +install kde will be killed so hard that even his ancestors will die (tm) +sinfest ). + +We can also use this to ensure a package is never installed ( just cut +and past the class, and change the list, and the ensure value. See +puppet doc for that . + +2) ssh_keys installation. + +Like packages, there is a type for ssh keys : + +class default_ssh_root_key { + ssh_authorized_key { "ssh key misc": + type => "ssh-rsa", + key => "insert-real-long-key-here", + user => "root" + } + ssh_authorized_key { "ssh key blino": + type => "ssh-dss", + key => "insert-real-longer-and-stronger-bigger-blino-key-here", + user => "root" + } +} + +this mean that my key ( and blino's one ) is added to the proper file +directly, with correct permission. I have added blino, nanar, dmorgan, +coling, dams and me. Others didn't send it yet. + + +that's for the basic part. Puppetmaster reload itself when it detect the +config change. And it refuse invalid config in case of problem as does +the puppet agent on each node. + + +So next, on each server ( the 4 one in LO, I am taking care of the gandi +vm as soon as I finished to write this mail ), I have setup the puppet +agent : + + +2) setup puppet +for each node : + + urpmi puppet + vim /etc/puppet/puppet.conf ( add a "server = valstar.mageia.org" + entry in [puppetd], will likely be taken care by puppet itself + later ) + service puppet start + +on valstar, to authenticate the request ( ie, when puppet is started, it +exchanges ssl certs with the master to encrypt future exchange ). + +puppetca --list +puppetca --sign server + +on the node that just signed : +tail -f /var/log/messages, see there is no error, and test that we can +still connect as root. +Beware, this changed with puppet 2.6 some months ago, so i suggest +people to read the documentation if they read this mail after the end of +2010 :). + +If you have any questions on how to use puppet after this quick +introduction, do not hesitate to ping me on irc, or better here so +everybody will get the answer. + + +-- +Michael Scherer + +</PRE> + + + + + + + + + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI>Previous message: <A HREF="000074.html">[Mageia-sysadm] ssh keys +</A></li> + <LI>Next message: <A HREF="000082.html">[Mageia-sysadm] ssh keys +</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#65">[ date ]</a> + <a href="thread.html#65">[ thread ]</a> + <a href="subject.html#65">[ subject ]</a> + <a href="author.html#65">[ author ]</a> + </LI> + </UL> + +<hr> +<a href="https://www.mageia.org/mailman/listinfo/mageia-sysadm">More information about the Mageia-sysadm +mailing list</a><br> +</body></html> |
