如何通过交互式身份验证修复systemctl？

如何解决如何通过交互式身份验证修复systemctl？

我有一个有趣的剧本来配置jenkins，该剧本作为cloud-init-script的一部分运行。

但是它在詹金斯重启期间失败了。任何人都可以让我知道其要求的交互式身份验证以及如何解决此问题吗？

版本： ansible == 2.9.6 jenkins_version：2.176.3

代码：

- name: Restart Jenkins
  service:
    name: jenkins
    state: restarted

- name: Wait for Jenkins to start up
  uri:
    url: http://localhost:8080
    user: "{{ jenkins_admin_username }}"
    password: "{{ jenkins_admin_password }}"
    force_basic_auth: true
    status_code: 200
    timeout: 5
  register: jenkins_service_status
  # Keep trying for 5 mins in 5 sec intervals
  retries: 60
  delay: 5
  until: >
     'status' in jenkins_service_status and
     jenkins_service_status['status'] == 200

错误：

解决方法

您很可能正在使用用户登录到不允许执行这些systemctl操作的目标。因此，您可能需要将become: true添加到任务中（请参阅documentation on become）：

- name: Restart Jenkins
  become: true
  service:
    name: jenkins
    state: restarted
