如何在 Centos 7 上使用 ansible firewalld 任务打开防火墙端口

Question

我的 ansible-playbook 脚本中有一个任务是在远程机器上打开 TCP 端口。但是当我运行我的 ansible 剧本时，它会抛出一个错误。但是当我运行 "firewall-cmd --permanent --zone=public --add-port=1234/tcp" 和 "firewalld-cmd --reload" 我可以看到端口被添加到 public 区域。

环境 Ansible 本地：OS x El Capitan Ansible 远程：AWS Centos 7 最低版本版本：2.1.1.0 远程 python 版本：2.7.5

我的任务

- name: open management console port
  firewalld: port=1234/tcp zone=public permanent=true state=enabled immediate=yes

我遇到的错误

Answer 1

dbus.exceptions.DBusException: org.fedoraproject.slip.dbus.service.PolKit.NotAuthorizedException.org.fedoraproject.FirewallD1.config 表示存在某种权限错误。该任务可能需要通过 become: yes.

提升其权限

有关详细信息，请参阅 the become documentation。

Answer 2

- name: Install firewalld
      yum:
        name: firewalld
        state: latest
      notify:
        - start firewalld
    - name: start firewalld
      service:
        name: firewalld
        state: started
        enabled: yes
      become: yes
    - name: enable 1234
      firewalld:
        zone: public
        port: 1234/tcp
        permanent: true
        state: enabled
      become: yes

这样做。它会起作用
