被監(jiān)控機(jī)安裝nrpe

準(zhǔn)備工作:

sudo apt-get install openssl

sudo apt-get install libcurl3-openssl-dev

添加用戶和組（nagios)

useradd nagios -s /sbin/nologin

groupadd nagios

1.下載與安裝NRPE:

wget http://prdownloads.sourceforge.net/sourceforge/nagios/nrpe-2.13.tar.gz

tar -zxf nrpe-2.13.tar.gz

cd nrpe-2.13

開始安裝:

./configure --with-ssl=/usr/bin/openssl --with-ssl-lib=/usr/lib/x86_64-linux-gnu（可能64位和32位有所不同）

make all

make install-plugin

make install-daemon

make install-daemon-config

2.下載與安裝nagios-plugins

wget http://assets.nagios.com/downloads/nagiosplugins/nagios-plugins-1.5.tar.gz

tar -zxvf nagios-plugins-1.5.tar.gz

cd nagios-plugins-1.5

./configure --prefix=/usr/local/nagios

make install

3.下載與安裝openmanage

http://folk.uio.no/trondham/software/check_openmanage.html#download

wget http://folk.uio.no/trondham/software/files/check_openmanage-3.7.11.tar.gz

tar -zxvf check_openmanage-3.7.11.tar.gz

cd check_openmanage-3.7.11

cp check_openmanage /usr/local/nagios/libexec/

編輯nrpe: /usr/local/nagios/etc/nrpe.cfg

添加與修改如下內(nèi)容：

allowed_hosts=127.0.0.1,222.247.*.*,222.247.*.*   加入允許連接的主機(jī)，多主機(jī)用逗號(hào)分開

command[check_disk]=/usr/local/nagios/libexec/check_disk -w 10% -c 5% -p /

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

command[check_boot]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /boot

command[check_sensors]=/usr/local/nagios/libexec/check_sensors

command[check_cputemp]=/usr/local/nagios/libexec/check_cputemp -m sensors -w 70 -c 85

command[check_hardware]=/usr/local/nagios/libexec/check_openmanage -e -t 200 --only critical

command[check_storage]=/usr/local/nagios/libexec/check_openmanage -s -t 200 --only storage -b ctrl_fw=0

command[check_power]=/usr/local/nagios/libexec/check_openmanage -s -t 200 --only power

command[check_memory]=/usr/local/nagios/libexec/check_openmanage -s -t 200 --only memory

command[check_fans]=/usr/local/nagios/libexec/check_openmanage -s -t 200 --only fans

command[check_temp]=/usr/local/nagios/libexec/check_openmanage -s -t 200 --only temp

command[check_cpu]=/usr/local/nagios/libexec/check_openmanage -s -t 200 --only cpu

command[check_voltage]=/usr/local/nagios/libexec/check_openmanage -s -t 200 --only voltage

command[check_batteries]=/usr/local/nagios/libexec/check_openmanage -s -t 200 --only batteries

啟動(dòng)nrpe

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

查看是否啟動(dòng)成功

ps -ef |grep nrpe

nagios    2638     1  0 12:45 ?        00:00:00 /usr/local/nagios/bin/nrpe -c

然后iptables開放端口：5666

vi /etc/iptables

-A INPUT -s 222.247.*.* -p tcp -m tcp --dport 5666 -j ACCEPT

或

#iptables -A INPUT -s 222.247.*.* -p tcp -m tcp --dport 5666 -j ACCEPT

#iptables-restore -c /etc/iptables.rules 即時(shí)生效。（不需要安裝iptables)

#iptables -L -n    查看規(guī)則

重啟nrpe，需要先kill進(jìn)程,然后再啟動(dòng)

如：

ps -ef |grep nrpe

nagios    2638     1  0 12:45 ?        00:00:00 /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

kill -9 2638

然后再啟動(dòng)：

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

也可以將腳本加入：/etc/rc.local 文件隨機(jī)啟動(dòng) ：

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

測(cè)試nrpe是否工作

/usr/local/nagios/libexec/check_nrpe -H localhost

服務(wù)器配置:

同樣安裝nrpe.

檢查命令行是否可查到被監(jiān)控主機(jī)nrpe信息:

/usr/local/nagios/libexec/check_nrpe -H 被監(jiān)控IP -c check_disk

日志文件

tail -f /var/log/syslog
