本篇內容主要講解“centos6.2怎么用nagios nrpe監控本地與遠程Linux主機”，感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷，實用性強。下面就讓小編來帶大家學習“centos6.2怎么用nagios nrpe監控本地與遠程Linux主機”吧!

假設我的監控主機ip是192.168.122.3，遠程被監控主機是192.168.122.14.兩個系統都是centos6.3系統。首先介紹監控本地主機。這部分很簡單，可以參考Nagios 官方指導文檔http://nagios.sourceforge.net/docs/3_0/quickstart-fedora.html，下面我只寫操作命令，不多贅述了。

1. yum -y install httpd httpd-devel php openssl-devel gcc glibc glibc-common gd gd-devel

2. /usr/sbin/useradd -m nagios

3. /usr/sbin/groupadd nagcmd

4. /usr/sbin/usermod -a -G nagcmd nagios

5. /usr/sbin/usermod -a -G nagcmd apache

6. wget http://iweb.dl.sourceforge.net/project/nagios/nagios-3.x/nagios-3.4.1/nagios-3.4.1.tar.gz

7. wget http://iweb.dl.sourceforge.net/project/nagiosplug/nagiosplug/1.4.16/nagios-plugins-1.4.16.tar.gz

8. tar xzf nagios-3.4.1.tar.gz

9. cd nagios

10. ./configure --with-command-group=nagcmd

11. make all

12. make install

13. make install-init

14. make install-config

15. make install-commandmode

16. vi /usr/local/nagios/etc/objects/contacts.cfg 修改你的email地址

17. make install-webconf

18. 為登錄Nagios Web接口創建nagiosadmin帳號。記住下面你設置的密碼，之后登錄用到
    htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin

19. service httpd restart

20. 安裝Nagios插件
    

1. tar xzf nagios-plugins-1.4.16.tar.gz

2. cd nagios-plugins-1.4.16

3. ./configure --with-nagios-user=nagios --with-nagios-group=nagios

4. make

5. make install

21.  設置Nagios開機自啟動

       chkconfig --add nagios

       chkconfig nagios on

22 測試配置文件是否有錯誤

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

23. 如果沒有，就啟動nagios  

       service nagios start

下面是介紹使用nrpe監控遠程主機

首先是遠程被監控主機的操作

1. wget http://iweb.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.13/nrpe-2.13.tar.gz

2. wget http://iweb.dl.sourceforge.net/project/nagiosplug/nagiosplug/1.4.16/nagios-plugins-1.4.16.tar.gz

添加nagios 帳號

3. useradd nagios; passwd nagios

安裝nagios-plugin

1. tar xvfz nagios-plugins-1.4.16.tar.gz

2. cd nagios-plugins-1.4.16

3. export LDFLAGS=-ldl

   
   

4. ./configure --with-nagios-user=nagios --with-nagios-group=nagios --enable-redhat-pthread-workaround

5. make

6. make install

   
   

7. chown nagios.nagios /usr/local/nagios
   

8. chown -R nagios.nagios /usr/local/nagios/libexec/

安裝nrpe

1. tar xvfz nrpe-2.13.tar.gz

2. cd nrpe-2.13

3. ./configure
   

4. make all

5. make install-plugin

6. make install-daemon

7. make install-daemon-config

8. yum install xinetd

9. make install-xinetd

更改/etc/xinetd.d/nrpe文件，設置允許nagios服務器連接,如nagios服務器的ip為192.168.122.3

only_from       = 127.0.0.1 192.168.122.3

在/etc/services結尾增加

nrpe         5666/tcp         # NRPE

啟動xinetd

service xinetd restart

驗證nrpe是否監聽

ss -an | grep 5666

測試nrpe是否正常工作

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

2. NRPE v2.13

更改 /usr/local/nagios/etc/nrpe.cfg
nrpe.cfg文件里包含需要監控遠程主機的命令，如：

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

======================================================================

下面是nagios服務器的操作

wget http://iweb.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.13/nrpe-2.13.tar.gz

tar xvfz nrpe-2.13.tar.gz
cd nrpe-2.13
./configure
make all
make install-plugin

測試是否正常

1. /usr/local/nagios/libexec/check_nrpe -H 192.168.122.14

      NRPE v2.13

在

在文件/usr/local/nagios/etc/objects/commands.cfg后面增加：

# 'check_nrpe' command definition

define command{

command_name check_nrpe

command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -t 30 -c $ARG1$

}

創建/usr/local/nagios/etc/objects/remotehost.cfg
host定義示例：

define host{

use linux-server

host_name defcon

address 192.168.122.14

}

Service定義示例：

define service{

use generic-service

service_description Root Partition

check_command check_nrpe!check_disk

}

然后echo “cfg_file=/usr/local/nagios/etc/objects/remotehost.cfg” >> /usr/local/nagios/etc/nagios.cfg"

service nagisos reload就可以查看到遠程主機和本地主機啦
