什么是Nagios？如何使用Nagios監控Linux郵件服務器？首先應該從被監控的主機入手，在nagios配置文件。本文講述的就是如何使用Nagios監控Linux郵件服務器。
Nagios監控Linux郵件服務器
首先在被監控主機上安裝:
- [root@mail src]# useradd nagios
- [root@mail src]# passwd nagios
- [root@mail src]# tar zxvf nagios-plugins-1.4.13.tar.gz
- [root@mail src]# cd nagios-plugins-1.4.13
- [root@mail nagios-plugins-1.4.13]# ./configure --prefix=/usr/local/nagios
- [root@mail nagios-plugins-1.4.13]# make
- [root@mail nagios-plugins-1.4.13]# make install
- [root@mail nagios-plugins-1.4.13]# chown -R nagios.nagios /usr/local/nagios
- [root@mail nagios-plugins-1.4.13]# cd ..
- [root@mail src]# tar zxvf nrpe-2.8.1.tar.gz
- [root@mail src]# cd nrpe-2.8.1
- [root@mail nrpe-2.8.1]# ./configure --prefix=/usr/local/nrpe
- [root@mail nrpe-2.8.1]# make all
- [root@mail nrpe-2.8.1]# make install-plugin
- [root@mail nrpe-2.8.1]# make install-daemon
- [root@mail nrpe-2.8.1]# make install-daemon-config
- [root@mail nrpe-2.8.1]# make install-xinetd
- [root@mail nrpe-2.8.1]# vim /etc/xinetd.d/nrpe
- only_from = 127.0.0.1 218.106.**.**
- [root@mail nrpe-2.8.1]# vim /etc/services
- # Local services
- nrpe 5666/tcp # nrpe
- [root@mail nrpe-2.8.1]# service xinetd restart
- [root@mail nrpe-2.8.1]# netstat -an|grep 5666
- tcp 0 0 0.0.0.0:5666 0.0.0.0:* LISTEN
- [root@mail nrpe-2.8.1]# /usr/local/nrpe/libexec/check_nrpe -H localhost
- NRPE v2.8.1
- [root@mail nrpe-2.8.1]# vim /usr/local/nrpe/etc/nrpe.cfg
- command[check_users]=/usr/local/nagios/libexec/check_users -w 5 -c 10
- command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20
- command[check_hdb1]=/usr/local/nagios/libexec/check_disk -w 20 -c 10 -p /dev/hdb1
- command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z
- command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200
- command[check_swap]=/usr/local/nagios/libexec/check_swap -w 20% -c 10%
在nagios服務器上設置：
- [root@eric ~]# /usr/local/nagios/libexec/check_nrpe -H 218.106.**.**
- NRPE v2.8.1
- [root@eric ~]# vim /usr/local/nagios/etc/objects/commands.cfg
