<> ||<>|| This page describes how to set up Nagios on Ubuntu. Somewhat replaces the [[Nagios2]] page. This guide was done using Ubuntu 7.10 (Gutsy Gibbon) Note that this information is no longer accurate for nagios3 (the latest version distributed with Karmic, etc.). See [[Nagios3]]. = Introduction = Nagios is an open source host, service and network monitoring program. The official homepage is http://nagios.org/ = Preparations = If you are going to use mysql or pgsql for database store then do install that first. {{{ sudo aptitude install mysql-server }}} And to make the db configuration easier, please install dbconfig-common first. If you don't, then you will have to set up the database manually. {{{ sudo aptitude install dbconfig-common }}} == Shortcut for both == {{{ sudo aptitude install dbconfig-common mysql-server }}} = Installation = Now it depends on what database you would like to use. The package name is nagios- where database can be text, pgsql or mysql. So for installing with the mysql option use the following at the command line: {{{ sudo apt-get install nagios-mysql }}} or use synaptic to install the package. == Shortcut == {{{ sudo aptitude install dbconfig-common mysql-server sudo aptitude install nagios-mysql }}} = Initial configuration = * Set the password for the ''nagiosadmin'' user. That's all to get it running! Navigate to http://nagios_server/nagios2 and log in to see your systems monitor. By default it monitors the machine it runs on and it's gateway to the Internet. = Configurationfiles = * /etc/apache2/conf.d/nagios = See also = * [[Nagios2]] * [[Zenoss]] ---- CategoryInternet CategoryNetworking
