Question

我在运行以下ansible-playbook时遇到错误： （我正在尝试在我的虚拟机上安装LAMP堆栈和wordpress） 错误似乎来自数据库 mysql_db和mysql_user是否有效命令来创建数据库和用户？

请帮助，谢谢。

错误代码：

ERROR! conflicting action statements

The error appears to have been in '/home/arnold/Documents/wordpress':    line 49, column 7, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:


    - name: Create database and user for wordpress

您在一项任务下有两个模块mysql_db和mysql_user：

- name: Create database and user for wordpress
   mysql_db: name={{ dbase }} state=present
   mysql_user: name={{ user }} password={{ parola }} priv=dbwordpress.*:ALL state=present
   notify:
       - restart mysql

将它们分为两个任务：

- name: Ensure the database for WordPress exists
  mysql_db: name={{ dbase }} state=present
  notify:
    - restart mysql

- name: Ensure the user for WordPress exists
  mysql_user: name={{ user }} password={{ parola }} priv=dbwordpress.*:ALL state=present
  notify:
   - restart mysql
