Vi servers.cfg更改如下：

刪除掉所有的hosts,替換所有的田朝陽(yáng)家用機(jī)為server96.example.com

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg 檢查語(yǔ)法錯(cuò)誤

/etc/init.d/nagios restart

用nagios監(jiān)控另外一臺(tái)主機(jī)上的MySQL

Server27 上yum install mysql-server

/etc/init.d/mysqld restart

Mysql

Create database nagdb;

Grant select on nagdb.* to nagios@’192.168.0.196’ ;

Server96 上

Cd /usr/local/nagio/libexec

./check_mysql --help

./check_mysql -H 192.168.0.127 -u nagios -d nagdb

Cd /usr/local/nagios/etc/objects/

Vi commands.cfg 更改如下：

#’check_mysql’ command definition

Define command{

Command_name check_mysql

Command_line $UER1$/check_mysql -H $HOSTADDRESS$ -u $ARG1$ -d $ARG2$

}

Vi hosts.cfg更改如下：

define host{

}

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg 檢查語(yǔ)法錯(cuò)誤

/etc/init.d/nagios reload

Vi contacts.cfg 設(shè)置監(jiān)控的內(nèi)容出現(xiàn)錯(cuò)誤時(shí)email通知的地址

Define contact{

}

/etc/init.d/nagios reload

nagios安裝好后，網(wǎng)頁(yè)訪問(wèn)出現(xiàn)如下錯(cuò)誤：

無(wú)權(quán)查看任何主機(jī)的信息。

請(qǐng)檢查HTTP服務(wù)器關(guān)于該CGI的訪問(wèn)權(quán)限設(shè)置。

解決辦法：

vi /usr/local/nagios/etc/cgi.cfg

將use_authentication的值改為0.

use_authentication=0

然后重啟nagios服務(wù)

service nagios restart

還有可能：

配置文件中的hostname和service_description使用了中文。

建議hostname和service_description 不要使用中文

Su - nagios

Mail [email protected] 發(fā)送測(cè)試郵件

在/usr/locl/nagios/var/ 查看nagios的日志nagios.log

用nagios監(jiān)控其他主機(jī)的磁盤，用戶，根分區(qū)等要在所要監(jiān)控的織機(jī)上安裝nagios的插件

Server27

Get nrpe-2.14.tar.gz

Useradd nagios

Get nagios-plugins-1.4.16.tar.gz

Tar nagios-plugins-1.4.16.tar.gz

Cd nagios-plugins-1.4.16

Yum install gcc make -y

./configure 配置出現(xiàn)如圖但要支持那些功能

Yum install –y mysql-devel openssl-devel

./configure

Cd nrpe-2.14

./configure

Make all

Make install-plugin

Make install-daemon

Make install-daemon-config

Make install-xinetd

Vi /etc/xinetd.d/nrpe 更改如下：

吧only-from = 192.168.0.196 改成這樣

Vi /etc/services 更改如下:
nrpe 5666/tcp 添加這一行讓xinetd接聽(tīng)nrpe的端口

/etc/init.d/xinetd start

Netstat -natple | grep 5666

Cd /usr/local/nagios/etc/

Vim nrpe.cfg 更改如下：

更改這行如command[check_disk]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /

/etc/init.d/xinetd restart

在server96上也安裝nrpe

Tar zxf nrpe-2.14.tar.gz

Cd nrpe-2.14

./configure

Make all

Make install-plugin

Cd /usr/local/nagios/libexec/

./check_nrpe -H 192.168.0.127

如果出現(xiàn)NRPE V2.14則配置成功

./check_nrpe -H 192.168.0.127 -c check_disk

./check_nrpe -H 192.168.0.127 -c check_users

Cd /usr/local/nagios/etc/objects/

Vi commands.cfg添加

Define command{

Command_name check_nrpe

Command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$

}

Vi services.cfg添加

Define servicegroup{

Servicegroup_name 系統(tǒng)負(fù)荷檢查

Alias 系統(tǒng)負(fù)荷

}

Define service{

Use local-service

Host_name server27.example.com

Service_description更分區(qū)

Check_command check_nrpe!check_disk

}

Define service{

Service_description 系統(tǒng)負(fù)荷

Check_command check_nrpe!check_load

}

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

/etc/init.d/nagios reload 這樣就可以在圖形中監(jiān)控另外一臺(tái)主機(jī)的根分區(qū)，登錄用戶等信息了。

當(dāng)系統(tǒng)出現(xiàn)問(wèn)題時(shí)用飛信給管理員發(fā)短信

如果提示要輸入驗(yàn)證碼則在一臺(tái)裝了圖形的主機(jī)上用ssh連接次主機(jī)然后cd /usr/local/nagios/libexec scp 13679270227.jpg 192.168.0.251:/home/wxh/Desktop(裝了圖形的主機(jī)) 然后再裝了圖形的主機(jī)上打開(kāi)此圖片得到驗(yàn)證碼
