This is how I got nagios to install on my Ubuntu 9.10 x86 server (LAMP):
\n***EDIT*** I’ve upgraded the 9.10 x86 server to 10.04LTS x86 and Nagios is still running like a champ. FYI.<\/p>\n
This assumes you’ve already got LAMP up and running on the box and have at least a little common sense when it comes to linux commands. I still use putty to connect via SSH to my box. I also cheated and made it so I don’t do sudo (sudo passwd root, then su into root). If you don’t want to do that, just add ‘sudo’ in front of all the commands.<\/p>\n
Update your box: Install the GCC compiler development libraries: Install GD development libraries: Create a new user “nagios”: Make a password for the new user: Create a new group “nagcmd” Download the nagios files – I use \/home\/username as my download point: Extract and compile the files: Create a nagiosadmin account for the web interface: Restart Apache That should be it for the installation phase of the main application. You can verify that everything works by viewing the site: http:\/\/localhost\/nagios (or http:\/\/ipofserver\/nagios) and logging in using nagiosadmin\/thepasswordyoupicked. But now we should probably put the plugins in place before actually going through any other setup.<\/p>\n Unpack the plugins: Configure and install the plugins: Verify that the sample nagios configuration files are fine: If there are no errors you can start nagios: http:\/\/localhost\/nagios http:\/\/www.monitoringexchange.org\/<\/p>\n INSTALL CLIENT ON WINDOWS MACHINE(S):<\/strong> Setting up for Windows Machine monitoring is a little more in depth:<\/p>\n Download the NSClient++: Install the Service and System Tray: Configure the NSClientpp Service: Edit the INI file: Uncomment the following:<\/p>\n FileLogger.dll Uncomment the hosts allowed file – either add the IP address of the Nagios server or just leave it blank and it will accept from all IPs.<\/p>\n Save the file, Start the service – I’ve had it work without interact with desktop, but it was recommended by Nagios to enable that feature.<\/p>\n Back on the Nagios server, edit the \/usr\/local\/nagios\/etc\/objects\/windows.cfg file to the liking of your windows machine. Verify your setup can run: Now you should be done. Login to your http:\/\/serverip\/nagios site with your nagiosadmin\/passwordyouchoseearlier account information.<\/p>\n As a side note, I also edited \/usr\/local\/nagios\/etc\/nagios.cfg for the admin_email= to send email to my account. I already have postfix installed from another project, so it *should* send me alert emails. AND I found that you have to edit \/usr\/local\/nagios\/etc\/objects\/contacts.cfg as well. After editing make sure you restart the nagios service.<\/p>\n ***EDIT***<\/p>\n I was receiving the emails just fine, but they were coming from the “wrong domain”. Ubuntu\/debian puts the domain name by default in the \/etc\/mailname file. Edit that file and then reload postfix. If the file does not exist (you’re creating a new file with nano), type in your domain name (ie thelibrarie.com), and then save the file. Then edit the postfix configuration and uncomment myorgin. myorigin = \/etc\/mailname<\/p><\/blockquote>\n And then try it again. You can test it out by sending yourself some mail: I also realized that I put how to install the client on Windows machines, so I should probably mention that in the subject, eh?<\/p>\n ***EDIT*** Add the permissions: Or you can comma-delimit the users. Either way, I win.<\/p>\n Restart nagios. ***EDIT 2*** ***EDIT 3*** This is how I got nagios to install on my Ubuntu 9.10 x86 server (LAMP): ***EDIT*** I’ve upgraded the 9.10 x86 server to 10.04LTS x86 and Nagios is still running like a champ.
