5、配置pnp4nagios

host_perfdata_file_processing_command=process-host-perfdata-file<span style="color:#333333">vim /usr/local/nagios/etc/objects/commands.cfg
define command{
command_name check_nrpe
command_line $USER1$/check_nrpe-H $HOSTADDRESS$ -c $ARG1$
} #这一段放在上面即可
如下：同步模式设定方法添加到末尾就可以，记住在这个配置文件里面， 默认有这个配置，需要找到注释掉，然后将下面的配置添加，如果不注释掉，在你检查nagios的配置文件的时候会报错

check_command check_ssh! -p 38383!192.168.1.16</span><span style="color:#333333"><strong>7、在被监控机上</strong>
a.增加用户
#useradd nagios -s /sbin/nologin
b.安装Nagios插件
# tar zxvf nagios-plugins-1.4.16.tar.gz
# cd nagios-plugins-1.4.16
# ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios
# make && make install
这一步完成后会在/usr/local/nagios/下生成三个目录include、libexec和share。
c.安装NRPE
# wget http://prdownloads.sourceforge.net/sourceforge/nagios/nrpe-2.13.tar.gz
# tar zxvf nrpe-2.13.tar.gz
# cd nrpe-2.13
# ./configure
make all
接下来安装NRPE插件，daemon和示例配置文件
c.1 安装check_nrpe 监控机需要安装check_nrpe这个插件，被监控机并不需要，我们在这里安装它只是为了测试目的。
[root@node2 nrpe-2.13]# make install-plugin
c.2 安装deamon
[root@node2 nrpe-2.13]# make install-daemon
c.3 安装配置文件
[root@node2 nrpe-2.13]# make install-daemon-config
按照安装文档的说明，是将NRPE deamon作为xinetd下的一个服务运行的。在这样的情况下xinetd就必须要先安装好，不过一般系统已经默认安装了。
yum install -y xinetd
d.安装xinetd脚本
[root@node2 nrpe-2.13]# make install-xinetd
可以看到创建了这个文件/etc/xinetd.d/nrpe
编译这个脚本：添加监控服务器IP,监控和被监控端都添加
[root@node2 ~]# vi /etc/xinetd.d/nrpe
only_from = 192.168.11.164 127.0.0.1
vi /usr/local/nagios/etc/nrpe.cfg
allowed_hosts=192.168.1.115,127.0.0.1,192.168.1.113
编辑/etc/services文件，增加NRPE服务
[root@node2 ~]# tail -n 4 /etc/services
iqobject 48619/tcp # iqobject
iqobject 48619/udp # iqobject
# Local services
nrpe 5666/tcp #nrpe
重启xinetd服务
[root@node2 ~]# service xinetd restart
Stopping xinetd: [ OK ]
Starting xinetd: [ OK ]
查看NRPE是否已经启动
[root@node2 ~]# netstat -an|grep 5666
tcp 0 0 0.0.0.0:5666 0.0.0.0:* LISTEN
使用上面在被监控机上安装的check_nrpe 这个插件测试NRPE 是否工作正常。
