Re: [Nagios-users] So its running how I like it
We use an ubuntu based PXE builder, but the same principle. We've deployed half a dozen nagios instances so far, another dozen to do by the end of the year.

Re: [Nagios-users] So its running how I like it
The dependencies, hand-config user-creation, and the creation of the ghost files, can be done with a proper RPM -- which then means that two installations (by different people) are able to help each other a bit easier. It may also help the original OT poster get a canned install with little hand-monkeying, so easier to approach a canned ISO or a VM disk image. Whether it's worth it depends on how much you'll use it. The config should always be seperate, and I'd suggest libexec too (We're always adding custom plugins). If you run in a mixed mode environment (some 32 bit, some 64), separate your architecture-independent perl scripts from your binaries by using two libexec directories. Paul, did you think of using the RPM, and indicating the shortfalls (such as the perl dependencies that aren't portable to the host's RPM dependencies -- those always pop up) or other issues with the RPM? We have 35 custom .debs in a local repository. One of our nagios checks runs apt-get update every night for security checking, so we see which machines need upgrades. We haven't written a plugin that needs a perl module which isn't in the OS repository. It's easier to keep uptodate that way, and there's arround 1400 perl modules in the apt Repositories. The testing that needs to go into the installation scripts (to do it right) for something like a nagios install is much more intensive than most, which files to remove in preperation for upgrade, which to purge, which not to purge, what to do on failed upgrades, etc. Much easier to run one command after another and check for errors yourself. -- Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H ___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
Re: [Nagios-users] So its running how I like it
There are several ways, depending on exactly what you want to accomplish and why you want to do it. Ultimately, think about what makes a Nagios server run perfectly. Primarily, it's the configuration files, probably in /etc/nagios, right? So you would want to tar those up to start with. You may have added some of your own plugins. Don't forget any scripts that you may have created. Any customized icons, graphics, etc. Don't forget the Apache configuration changes and any Apache modules you may need. And remember any user names that you may have created for nagios to run under. Once you have all the various customizations that you did to accomplish where you are now, you have several options: The closest to what you are asking for is probably to simply put all the customizations into a tar file (or similar). When you need to install afresh, simply install your choice of operating system. Then untar the nagios file you prepared earlier, and everything *should* be back in place (with the possible exception of file ownerships and permissions). Theory being what it is, you will probably have to do a little bit of touchup. Another possibility is to create a live CD. In that case, Linux never gets installed, it runs right off the CD. Of course status changes, as well as some configuration information (such as IP address) has to be on a hard disk or memory stick. You can make as many copies of it as you need. Or you could virtualize your Nagios server. That is what I did. Moving or copying Nagios to another server is as simple as copying a directory with about ten files (a couple GB of data, so it does take a little while). Copying will obviously also mean a few configuration changes.
