If the desired behavior is to reload the service, then set the reload value to True: （服務默認情況是restart，如果要執行reload，你們就要把reload設置為true） 案例： redis: service.running: - enable: True - reload: True - watch: - pkg: redis 或者： service.running: - name: redis - enable: True - reload: True - watch - pkg: redis Note: More details regarding ``watch`` can be found in the :doc:`Requisites </ref/states/requisites>` documentation. 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 總結： 1、常用的參數有如下 enable： True reload: True ~~~ 案例： service.running: - name: sshd - enable: True - reload: True - require: - file: ssh-managed 關閉服務： - service.disabled ~~~ 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 ~~~ 案例： service.disabled: - name: rpcbind 2）判斷目標服務器上某個服務是否可用 [admin@master init]$ sudo salt 'node2.51yuki.cn' service.available sshd node2.51yuki.cn: True 3）重新加載指定服務 [admin@master init]$ sudo salt 'node2*' service.reload sshd node2.51yuki.cn: True 4) 重新啟動指定服務 [admin@master init]$ sudo salt 'node2*' service.restart sshd node2.51yuki.cn: True 5） 查看指定服務的狀態 [admin@master init]$ sudo salt 'node2*' service.status sshd node2.51yuki.cn: True
