# Define a host for the local machine

        use                     linux-server

        host_name               1.3-samba

        alias                   1.3-samba

        }

儲存退出

檢查文法，先編輯nagios檔案,使出錯資訊顯示出來

[[email protected] objects]# vim /etc/init.d/nagios +183

 $NagiosBin -v $NagiosCfgFile > /dev/null 2>&1;   修改為：

 $NagiosBin -v $NagiosCfgFile

儲存退出

檢查文法，如果報錯如下：

[[email protected] objects]# /etc/init.d/nagios checkconfig

Checking services...

Error: There are no services defined!

        Checked 0 services.

解決方案：

[[email protected] objects]# vi services.cfg 

define service {

        use                     generic-service

        host_name               1.3-samba

        service_description     Disk Partition

        check_command           check_nrpe!check_disk

} 

再檢查文法

[[email protected] objects]# /etc/init.d/nagios checkconfig

Total Warnings: 1

Total Errors:   0

Things look okay - No serious problems were detected during the pre-flight check

 OK.

[[email protected] objects]# 

如果報下面錯誤：

Error:Service check command ‘check_nrpe‘ specified in service ‘Disk Partition‘ for

 host ‘10-client01‘ not defined anywhere!

則編輯commands.cfg 檔案：

[[email protected] objects]# vi commands.cfg

再末尾加上

# ‘check_nrpe‘ command definition

define command{

        command_name    check_nrpe

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

        }

注意：command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ 實際上就是使用這個命令探測：

[[email protected] objects]#/usr/local/nagios/libexec/check_nrpe -H 10.89.1.3 -c check_disk

儲存並退出

再檢查文法

[[email protected] objects]# /etc/init.d/nagios checkconfig

沒有錯誤的情況下：

[[email protected] objects]# /etc/init.d/nagios reload

Running configuration check...done.

Reloading nagios configuration...done

[[email protected] objects]#

如果登入後提示錯誤：

It appears as though you do not have permission to view information for any of the hosts you requested...

If you believe this is an error, check the HTTP server authentication requirements for accessing this CGI

and check the authorization options in your CGI configuration file.

編輯 cgi.cfg

[[email protected] objects]# cd ../

[[email protected] etc]# vi cgi.cfg

# PHYSICAL HTML PATH

# This is the path where the HTML files for Nagios reside.  This

# value is used to locate the logo images needed by the statusmap

# and statuswrl CGIs.

physical_html_path=/usr/local/nagios/share

:g/nagiosadmin/s//alvin/g           #替換nagiosadmin 為 alvin，該使用者是我安裝的時候添加的

儲存並退出

[[email protected] objects]# /etc/init.d/nagios reload
