保存退出
检查语法，先编辑nagios文件,使出错信息显示出来
[[email protected] 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：
[[email protected] objects]# /etc/init.d/nagios checkconfig
Checking services...
Error: There are no services defined!
Checked 0 services.
解决方法：
[[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
}
再检查语法
[[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：
[[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 $ARG1$ 实际上就是使用这个命令探测：
[[email protected] 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
[[email protected] objects]# /etc/init.d/nagios checkconfig
没有错误的情况下：
[[email protected] objects]# /etc/init.d/nagios reload
Running configuration check...done.
Reloading nagios configuration...done
[[email protected] objects]#

如果登录后提示错误：

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

编辑 cgi.cfg
