2. salt-minion:
       ----------
       service:
           
           Starting or restarting of services and daemons
           ==============================================
           
           Services are defined as system daemons typically started with system init or
           rc scripts, services can be defined as running or dead.
           
               httpd:
                 service.running: []
           
           The service can also be set to be started at runtime via the enable option:
           
               openvpn:
                 service.running:
                   - enable: True
           
           By default if a service is triggered to refresh due to a watch statement the
           service is by default restarted. If the desired behavior is to reload the
           service, then set the reload value to True:
           
               redis:
                 service.running:
                   - enable: True
                   - reload: True
                   - watch:
                     - pkg: redis
           
           Note:
           
               More details regarding ``watch`` can be found in the
               :doc:`Requisites </ref/states/requisites>` documentation.
           
       service.dead:
           
               Ensure that the named service is dead by stopping the service if it is running
           
               name
                   The name of the init or rc script used to manage the service
           
               enable
                   Set the service to be enabled at boot time, ``True`` sets the service
                   to be enabled, ``False`` sets the named service to be disabled. The
                   default is ``None``, which does not enable or disable anything.
           
               sig
                   The string to search for when looking for the service process with ps
               
       service.disabled:
           
               Verify that the service is disabled on boot, only use this state if you
               don‘t want to manage the running process, remember that if you want to
               disable a service to use the enable: False option for the running or dead
               function.
           
               name
                   The name of the init or rc script used to manage the service
               
       service.enabled:
           
               Verify that the service is enabled on boot, only use this state if you
               don‘t want to manage the running process, remember that if you want to
               enable a running service to use the enable: True option for the running
               or dead function.
           
               name
                   The name of the init or rc script used to manage the service
               
       service.mod_watch:
           
               The service watcher, called to invoke the watch command.
           
               name
                   The name of the init or rc script used to manage the service
           
               sfun
                   The original function which triggered the mod_watch call
                   (`service.running`, for example).
           
               sig
                   The string to search for when looking for the service process with ps
               
       service.running:
           
               Verify that the service is running
           
               name
                   The name of the init or rc script used to manage the service
           
               enable
                   Set the service to be enabled at boot time, True sets the service to
                   be enabled, False sets the named service to be disabled. The default
                   is None, which does not enable or disable anything.
           
               sig
                   The string to search for when looking for the service process with ps

       - enable: True
       - reload: True
   
   service-reload:
     - cmd.run:
       - `which nginx` -s reload
   
   备注：上面的 sls中，存在一个bug，现象是，如果conf文件改变，nginx不会reload，配置不生效， 具体原因不清楚，不过可以使用出cmd模块解决。
