nagios監控linux nrpe安裝

1、下載nrpe2.15

  wget http://cznic.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.15/nrpe-2.15.tar.gz

2、yum install openssl openssl-devel

   cd nrpe-2.15

   ./configure --enable-ssl --with-nagios-user=nagios --with-nagios-group=nagcmd --with-nrpe-user=nagios --with-nrpe-group=nagcmd

   make all

   make install-plugin

   make install-daemon

   make install-daemon-config

   make install-xinetd

3、編輯nrpe配置文件，增加監控機地址：   

      vi /etc/xinetd.d/nrpe

      only_from = nagios-server-ip,127.0.0.1

4、編輯vi /usr/local/nagios/etc/nrpe.cfg

      allowed_hosts=nagios-server-ip,127.0.0.1

5、修改services文件，增加端口
          vi /etc/services
          nrpe            5666/tcp                        #NRPE

6、啟動 nrpe

   /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

   設置開機啟動

   vi /etc/rc.d/rc.local加入/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

   驗證是否啟動

   netstat -an |grep 5666  

   tcp        0      0 0.0.0.0:5666                0.0.0.0:*                   LISTEN    

7、報錯

   1）NRPE: Command 'check_hda1' not defined

   解決方法：

   nagios主機與被監控linux同時修改：vi /usr/local/nagios/etc/nrpe.cfg

     將command[check_hda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/hda1

    修改為  command[check_sda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/sda1

    注意 sda1為需要監控的分區

   2）NRPE: Command 'check_swap' not defined

   解決方法：

   nagios主機與被監控linux同時修改：vi /usr/local/nagios/etc/nrpe.cfg

   增加command[check_swap]=/usr/local/nagios/libexec/check_swap -w 20% -c 10%
