ansible:如何在centos 7上重新启动auditd服务得到关于依赖的错误

在我的剧本中，我有一个更新 audit.rules 的任务，然后通知应该重新启动 auditd 服务的处理程序。

`task:
  `-` name:  `6.6.7` `-` `audit` `rules` `configuration`
    template: `src=X/ansible/templates/auditd_rules.j2`
              `dest=/etc/audit/rules.d/audit.rules`
              `backup=yes`
              `owner=root` `group=root` `mode=0640`
     notify:
   `-` `restart` `auditd`


  handlers:
    `-` name: `restart` `auditd`
      service: `name=auditd` `state=restarted`
`

当 playbook 运行时，会更新审计规则并请求重新启动 auditd，但这会失败，如下所示。

`RUNNING HANDLER [restart auditd] `************************************************ fatal: [ipX-southeast-2.compute.internal]: FAILED! => {"changed": false, "failed": true, "msg": "Unable to restart service auditd: Failed to restart auditd.service: Operation refused, unit auditd.service may be requested by dependency only.\n"}*

当我查看auditd 的单元定义时，我可以看到rejectManualStop=yes。这就是我无法重新启动服务的原因吗？一个人如何来接受新的审计规则？

• 使用 ansible service模块参数use=service强制执行 /sbin/service实用程序而不是 systemd 的聚集事实值(调用 /sbin/systemctl )像这样:
• - service: name=auditd state=restarted use=service
• Example playbook (pastebin.com)
• 解决方法:
• 使用 ansible command模块来显式运行服务可执行文件，如下所示:
• - command: /sbin/service auditd restart
• 分析------根本原因:

  • This is an issue created by upstream packaging of auditd.service unit. It will not start/stop/restart when acted upon by systemctl, apparently by design.
  • It is further compounded by the Ansible service control function, which uses the preferred method identified when system facts are gathered and "ansible_service_mgr" returns "systemd". This is regardless of the actual module used to manage the service.unit.
  • RHEL dev team may fix if considered a problem in upcoming updates (ERRATA)
  • Ansible dev team has offered a workaround and (as of 2.2) updated the service module with the use parameter.

简单来说就是auditd开发者觉着auditd是系统底层记录日志的服务，不应由管理员重启或停止其服务。

解决方法：

1、使用service auditd restart可以绕过systemctl重启auditd服务。

2、修改systemd服务配置文件/usr/lib/systemd/system/auditd.service配置``RefuseManualStop=No``，执行systemctl deamon-reload。后可以使用systemctl restart auditd

在ansible-play里，1、可以使用command模块代替service模块，重启auditd服务。

• command: /sbin/service auditd restart

或者2、修改auditd.service配置文件，使systemctl可以管理auditd
