檢查語法,先編輯nagios文件,使出錯信息顯示出來
[root@nagios objects]# vim /etc/init.d/nagios +183
$NagiosBin -v $NagiosCfgFile > /dev/null 2>&1; 修改為:
$NagiosBin -v $NagiosCfgFile
保存退出
檢查語法,如果報錯如下:
[root@nagios objects]# /etc/init.d/nagios checkconfig
Checking services...
Error: There are no services defined!
Checked 0 services.
解決方法:
[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
}
再檢查語法
[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 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 $ARG1$ 實際上就是使用這個命令探測:
[root@nagios objects]#/usr/local/nagios/libexec/check_nrpe -H 10.89.1.3 -c check_disk
保存并退出
再檢查語法
[root@nagios objects]# /etc/init.d/nagios checkconfig
沒有錯誤的情況下:
[root@nagios objects]# /etc/init.d/nagios reload
Running configuration check...done.
Reloading nagios configuration...done
[root@nagios objects]#

如果登錄后提示錯誤:

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
[root@nagios objects]# cd ../
[root@nagios etc]# vi cgi.cfg
