Nagios 调试

如下，默认情况下，我们去检查 Nagios 语法的时候，如果语法错误，只会提示语法错误而不会提示详细的错误信息，因此我们有必要修改 Nagios 的启动配置脚本，使得执行 checkconfig 的时候能够出现详细的错误信息

[[email protected] ~]# /etc/init.d/nagios checkconfig
Running configuration check... CONFIG ERROR!  Check your Nagios configuration.

配置 Nagios 启动脚本：

[[email protected] ~]# vim /etc/init.d/nagios +178
            checkconfig)
                printf "Running configuration check..."
                $NagiosBin -v $NagiosCfgFile;

[[email protected] ~]# /etc/init.d/nagios checkconfig
Running configuration check...
