我在剧本中有一个任务，试图照常通过处理程序重启nginx：

  name: restart nginx  
  service: name=nginx state=restarted

它给了我以下错误：

RUNNING HANDLER [webtier : restart nginx] **************************************
fatal: [vagrant]: FAILED! => {"changed": false,"msg": "Unable to restart service nginx: Failed to restart nginx.service: Connection timed out\nSee system logs and 'systemctl status nginx.service' for details.\n"}

但是直到最后一次 sudo：是命令仍在起作用。并且上面的错误不会出现。

但是这次，通过添加 sudo：是命令

  name: restart nginx  
  service: name=nginx state=restarted
  sudo: yes 

给出以下错误：

ERROR! conflicting action statements: service,sudo

The error appears to be in '/Users/mac/Documents/GitHub/petalandstem/ansible/roles/webtier/handlers/main.yml': line 28,column 3,but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:


- name: restart nginx
  ^ here

Ansible failed to complete successfully. Any error output should be
visible above. Please fix these errors and try again.

如何成功重启nginx？
