wgethttp://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、编辑nrpe配置文件,增加监控机地址:
vi /etc/xinetd.d/nrpe
only_from = nagios-server-ip,127.0.0.1
4、编辑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、启动 nrpe
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
设置开机启动
vi /etc/rc.d/rc.local加入/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
验证是否启动
netstat -an |grep 5666
tcp 0 0 0.0.0.0:5666 0.0.0.0:* LISTEN
7、报错
1)NRPE: Command 'check_hda1' not defined
解决方法:
nagios主机与被监控linux同时修改:vi /usr/local/nagios/etc/nrpe.cfg
将command[check_hda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/hda1
修改为 command[check_sda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/sda1
注意 sda1为需要监控的分区
2)NRPE: Command 'check_swap' not defined
解决方法:
nagios主机与被监控linux同时修改:vi /usr/local/nagios/etc/nrpe.cfg
增加command[check_swap]=/usr/local/nagios/libexec/check_swap -w 20% -c 10%
