nagios-plugins、nrpe插件安装

useradd -s /sbin/nologin nagios

tar zxf nagios-plugins-1.4.14.tar.gz
cd nagios-plugins-1.4.14
   76  ./configure --prefix=/usr/local/nagios
   77  make
   78  make install
   79  chown nagios.nagios /usr/local/nagios
   80  chown -R nagios.nagios /usr/local/nagios/libexec
 

tar zxf nrpe-2.12.tar.gz

cd nrpe-2.12
 ./configure --prefix=/usr/local/nagios
   86  make all
   87  make install-plugin
   88  make install-daemon
   89  make install-daemon-config
       

/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d  启动nrpe
把上面的命令添加到/etc/rc.d/rc.local/便于开机启动nrpe
使用nrpe里面默认的命令即可监控主机上的资源
vi  /usr/local/nagios/nrpe.cfg
allowed_hosts=127.0.0.1,192.168.100.237

修改完以上文件后要执行 pkill nrpe然后再 /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
否则nagios监控端 执行  /usr/local/nagios/libexec/check_nrpe -H （被监控端ip192.168.100.78）会报错如下
CHECK_NRPE: Error - Could not complete SSL handshake.
