安装nrpe的过程：
- 安装nrpe客户端：
- [root@svr1 ~]# useradd nagios nagios安装
- [root@svr1 ~]# tar -xzf nagios-plugins-1.4.15.tar.gz
- [root@svr1 ~]# cd nagios-plugins-1.4.15
- [root@svr1 nagios-plugins-1.4.15]# ./configure
- [root@svr1 nagios-plugins-1.4.15]# make && make install 开源监控软件
- [root@svr1 ~]# tar -xzf nrpe-2.12.tar.gz
- [root@svr1 ~]# cd nrpe-2.12
- [root@svr1 nrpe-2.12]# ./configure
- *** Configuration summary for nrpe 2.12 03-10-2008 ***:

- service nrpe
- {
- flags = REUSE
- socket_type = stream
- port = 5666
- wait = no
- user = nagios
- group = nagios
- server = /usr/local/nagios/bin/nrpe
- server_args = -c /usr/local/nagios/etc/nrpe.cfg --inetd 监控软件
- log_on_failure += USERID
- disable = no
- only_from = 10.1.1.40
- }
- [root@svr1 nrpe-2.12]# service xinetd restart
- Stopping xinetd: [ OK ]
- Starting xinetd: [ OK ]
- [root@svr1 nrpe-2.12]# chkconfig --list | grep nrpe
- nrpe: on
- [root@svr1 nrpe-2.12]# netstat -tnlp | grep nrpe
- tcp 0 0 0.0.0.0:5666 0.0.0.0:* LISTEN 25360/nrpe
- [root@svr1 nrpe-2.12]# vim /usr/local/nagios/etc/nrpe.cfg
- 修一行：
- allowed_hosts=127.0.0.1,10.1.1.40
- 本机测试！
- [root@svr1 nrpe-2.12]# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
- [root@svr1 nrpe-2.12]# /usr/local/nagios/libexec/check_nrpe -H localhost -c check_load
- OK - load average: 0.00, 0.00, 0.00|load1=0.000;15.000;30.000;0; load5=0.000;10.000;25.000;0; nagios实施
- load15=0.000;5.000;20.000;0;
- 备注：有时候在客户端本机上测试时，发现会报错。CHECK_NRPE: Error - Could not complete SSL handshake.
- 这个时候，注意下xinetd.d/nrpe 以及nrpe.conf 里关于allowed相关的选项，另外就是防火墙。
- 使用xinetd后发现重启xinetd并不能重启nrpe,只有将其 T掉然后再开。
- 从远程主机上测试下：
- [root@svr4 ~]# /usr/local/nagios/libexec/check_nrpe -H 10.1.1.10 -c check_total_procs nagios培训
- PROCS CRITICAL: 249 processes
- 监控一下客户机的81，82服务吧！详见下篇
