Thanks to: Ryan Larson Jeff Kennedy Chris Dupre and sorry if I forgot anyone else. Recommendations: rdist, NIS/NIS+, and cfengine were suggested the most. NIS/NIS+ or LDAP for the user authentication portion, and cfengine or rdist for the file alignment. I've not yet had a chance to set up cfengine, but it looks like that is mostly what I was looking for. We already have some in house rdist scripts, but I'd like to have something a little more robust. Thanks everyone! =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Mike Marcell The Arizona Republic mike.marcell@pni.com Systems Database Administrator Phone: (602) 444-4958 Fax: (602) 444-8010 Pager: (602) 409-6248 Cell: (602) 568-1893 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= mike.marcell@pni.com Sent by: To: sunmanagers@sunmanagers.org sunmanagers-admin@sunm cc: anagers.org Subject: Keeping critical files aligned in a multi-node cluster Composed Date:02/14/2002 03:42 PM I'm curious as to the best way to keep various files aligned between all servers in a multi-node cluster. Our cluster is only a 3 node cluster, but the same concepts should apply. I'm referring to files like /etc/passwd, /etc/shadow, /etc/group, /etc/system and so on. Files that you want to remain consistent across all systems, and I don't want update three files for each change. One a two node cluster that we have, I've got a simple rdist script that 1st checks to see which system is active, and then compares files from a list to that on the in-active server, aligning them accordingly. So if I change a user's passwd on one system, I don't have to do it on both systems. Is there an efficient way of doing this on more than 2 servers? What do people with large multi-node clusters do? We're running 3 4500's, Solaris 2.8 and VCS 2.0. I will summarize. Thanks! =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Mike Marcell The Arizona Republic mike.marcell@pni.com Systems Database Administrator Phone: (602) 444-4958 Fax: (602) 444-8010 Pager: (602) 409-6248 Cell: (602) 568-1893 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= _______________________________________________ sunmanagers mailing list sunmanagers@sunmanagers.org http://www.sunmanagers.org/mailman/listinfo/sunmanagers _______________________________________________ sunmanagers mailing list sunmanagers@sunmanagers.org http://www.sunmanagers.org/mailman/listinfo/sunmanagersReceived on Fri Feb 22 11:15:15 2002
