保存退出

检查语法，先编辑nagios文件,使出错信息显示出来

[root@nagios objects]# vim /etc/init.d/nagios +183

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

 $NagiosBin -v $NagiosCfgFile

保存退出

检查语法，如果报错如下：

[root@nagios objects]# /etc/init.d/nagios checkconfig

Checking services...

Error: There are no services defined!

        Checked 0 services.

解决方法：

[root@nagios objects]# vi services.cfg 

define service {

        use                     generic-service

        host_name               1.3-samba

        service_description     Disk Partition

        check_command           check_nrpe!check_disk

} 

再检查语法

[root@nagios 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.

[root@nagios objects]# 

如果报下面错误：

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

 host '10-client01' not defined anywhere!

则编辑commands.cfg 文件：

[root@nagios 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 $ARG1$ 实际上就是使用这个命令探测：

[root@nagios objects]#/usr/local/nagios/libexec/check_nrpe -H 10.89.1.3 -c check_disk

保存并退出

再检查语法

[root@nagios objects]# /etc/init.d/nagios checkconfig

没有错误的情况下：

[root@nagios objects]# /etc/init.d/nagios reload

Running configuration check...done.

Reloading nagios configuration...done

[root@nagios objects]# 

http://10.89.1.2/nagios

如果登录后提示错误：

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.

编辑 cgi.cfg

[root@nagios objects]# cd ../

[root@nagios 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 p_w_picpaths needed by the statusmap

# and statuswrl CGIs.

physical_html_path=/usr/local/nagios/share

:g/nagiosadmin/s//alvin/g           #替换nagiosadmin 为 alvin，该用户是我安装的时候添加的

保存并退出

[root@nagios objects]# /etc/init.d/nagios reload
