nagios 配置報錯，Error: Service has no hosts and/or service_description，解決

Error: Service has no hosts and/or service_description

今天配置nagios的時候，遇到一個報錯，頗為頭疼了一段時間，特此記錄。

環境：centos6.5  nagiso 4.0.8

故障現象：

# /usr/local/nagios/bin/nagios -v  /usr/local/nagios/etc/nagios.cfg

Nagios Core 4.0.8

Reading configuration data...

   Read main config file okay...

Error: Service has no hosts and/or service_description (config file '/usr/local/nagios/etc/objects/templates.cfg', starting on line 188)

   Error processing object config files!

***> One or more problems was encountered while processing the config files...

     Check your configuration file(s) to ensure that they contain valid

     directives and data defintions.  If you are upgrading from a previous

     version of Nagios, you should be aware that some variables/definitions

     may have been removed or modified in this version.  Make sure to read

     the HTML documentation regarding the config files, as well as the

     'Whats New' section to find out what has changed.

問題原因：

# vim templates.cfg

# Local service definition template - This is NOT a real service, just a template!

define service{

        name                            local-service           ; The name of this service template

        use                             generic-service         ; Inherit default values from the generic-service definition

        max_check_attempts              4                       ; Re-check the service up to 4 times in order to determine its final (hard) state

        normal_check_interval           5                       ; Check the service every 5 minutes under normal conditions

        retry_check_interval            1                       ; Re-check the service every minute until a hard state can be determined

        register                        0                       ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL SERVICE, JUST A TEMPLATE!

        }

define service{

        name                            dkdh-service

        check_interval                  5

        retry_interval                  1

        max_check_attempts              4

        check_command                   check-host-alive        ; Default command to check if routers are "alive"

        check_period                    24x7

        process_perf_data               0

        retain_nonstatus_information    0

        contact_groups                  dkdhadmins

        notification_interval           5

        notification_period             24x7

        notification_options            w,u,c,r

        register                        0

        }

上面紅色字體的配置項，一開始沒有寫，添加之后解決。

故障分析：

該配置項的含義 DONT REGISTER THIS DEFINITION - ITS NOT A REAL SERVICE, JUST A TEMPLATE!可以看出該配置項主要是判斷是否該服務是模板，一般在該配置文件我們都建為模板，不作為實際使用的服務。由其他地方調用。如果不配置默認值可能是1（待驗證）會認為這個是要啟動的服務，但是找不到關聯的主機，所以報錯。

如有錯誤請斧正。
