监控机上安装nagios插件和nrpe(nrpe添加为xinetd服务)
1、添加nagios用户
/usr/sbin/useradd nagios
passwd nagios
2、安装nagios插件:
cd /usr/local/src
tar zxvf nagios-plugins-1.4.15.tar.gz
cd nagios-plugins-1.4.15
./configure --with-nagios-user=nagios --with-nagios-group=nagios
make
make install
3、安装nrpe:
cd /usr/local/src
tar -zxvf nrpe-2.12.tar.gz
cd nrpe-2.12
./configure --prefix=/usr/local/nagios
make all
make install-plugin
make install-daemon
make install-daemon-config
make install-xinetd #nrpe安装为xinetd服务
编辑nrpe配置文件,增加监控机地址:
vi /etc/xinetd.d/nrpe
only_from = 127.0.0.1 172.16.3.56 #172.16.3.56是监控服务器IP
修改services文件,增加端口
vi /etc/services
nrpe 5666/tcp #NRPE
安装xinetd,并重启xinetd服务
yum -y install xinetd
service xinetd restart
检查目录及文件:
ll /usr/local/nagios/libexec
看看里面是不是有一大堆check的什么东西,如果有就对了。
