安装nagios插件
-----------------------
nagios-plugin.xx.xx
-----------------------
源码地址：http://sourceforge.net/projects/nagiosplug/
# tar xf nagios-plugin.xx.xx
# cd nagios-plugin.xx.xx
# ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios
# make && make install
# pwd
/usr/local/nagios/libexec
// 插件安装后的文件
-----------------------
nrpe
监控linux本地主机时，我们可以直接更改配置文件进行监控，如果需要监控的主机与nagios不在同一机器上，即监控远程linux主机时，需要借助NRPE插件实现。
-----------------------
源码地址：http://sourceforge.net/projects/nrpe/?source=directory
# ./configure
# make
# make all
# make install-plugin
# make install-daemon
# make install-daemon-config
# vim /usr/local/nagios/etc/nrpe.cfg
allowed_hosts=127.0.0.1,192.168.1.20 #逗号隔开,授权Server获取check_nrpe
# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg ‐d //启动
# /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1 //输出表示nrpe配置成功
NRPE v2.12
