20.1. Install
20.1.1. Nagios core
Nagios 是一种开放源代码监视软件，它可以扫描主机、服务、网络方面存在的问题。Nagios 与其他类似的包之间的主要区别在于，Nagios 将所有的信息简化为“工作（working）”、“可疑的（questionable）”和“故障（failure）”状态，并且 Nagios 支持由插件组成的非常丰富的“生态系统”。这些特性使得用户能够进行有效安装，在此过程中无需过多地关心细节内容，只提供他们所需的信息即可。
install
$ sudo apt-get install nagios3 nagios-nrpe-plugin
add user nagiosadmin for nagios
$ sudo htpasswd -c /etc/nagios2/htpasswd.users nagiosadmin New password: Re-type new password: Adding password for user nagiosadmin
Create a new nagcmd group for allowing external commands to be submitted through the web interface. Add both the nagios user and the apache user to the group.
$ groupadd nagcmd $ sudo usermod -a -G nagcmd nagios $ sudo usermod -a -G nagcmd www-data $ cat /etc/group nagcmd:x:1003:nagios,www-data
reload apache
$ sudo /etc/init.d/apache2 reload * Reloading web server config apache2 [ OK ]
