1、安装NRPE插件

首先需要在Nagios服务器上安装NRPE插件，在Ubuntu系统中，可以通过以下命令安装：

“`

sudo aptget install nagiosnrpeserver nagiosplugins

“`

对于其他Linux发行版，可以参考官方文档进行安装。

2、配置NRPE插件

编辑NRPE配置文件/etc/nagios3/nrpe.cfg，设置以下参数：

“`

# 指定允许访问NRPE的主机或IP地址

allow_hosts=127.0.0.1,192.168.1.0/24

# 指定NRPE监听的端口

port=5666

“`

保存并退出。

3、重启NRPE服务

“`

sudo service nagios3nrpeserver restart

“`

4、在被监控主机上安装NRPE客户端插件

在需要监控的主机上，安装NRPE客户端插件，在Ubuntu系统中，可以通过以下命令安装：

“`

sudo aptget install nagiosnrpeclient nagiosplugins

“`

对于其他Linux发行版，可以参考官方文档进行安装。

5、配置NRPE客户端插件

编辑NRPE客户端配置文件/etc/nagios3/nrpe.cfg，设置以下参数：

“`

# 指定NRPE服务器的地址和端口

server=192.168.1.100

port=5666

“`

保存并退出。

6、重启NRPE客户端服务

“`

sudo service nagios3nrpeclient restart

“`

7、安装Ganglia插件

下载Ganglia插件包，解压并进入解压后的目录：

“`

wget http://ganglia.sourceforge.net/files/ganglia3.7.1.tar.gz

tar zxvf ganglia3.7.1.tar.gz

cd ganglia3.7.1/gmetad/python/gmond/ext/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src/nagiosgrapher/nagiosgrapher2.3.0/src /usr/local/libexec # 根据实际路径修改
