Ansible 失败:需要 python mysqldb 模块

请告诉我如何在 Debian 9 中安装 mysql_db 模块。我正在用 ansible 编写剧本。需要创建一个数据库和用户。ansible 文档说 mysql_db 模块用于此目的。在同一页的下面有信息

可以使用 apt-get install python-pymysql 安装 Python 包

我根据场外 Ansible 的说明进行安装。

xxxx@instance-3:/etc/ansible$ sudo apt-get install python-pymysql

接下来我尝试启动剧本。

xxxx@instance-3:/etc/ansible$ ansible-playbook db.yml

简短回答

在远程主机上安装 python mysqldb 模块。

细节

失败!=> {...“msg”:“需要 python mysqldb 模块”...

引自要求

执行此模块的主机需要满足以下要求。

  • MySQLdb(Python 2.x)
  • PyMySQL(Python 2.7 和 Python 3.X),或
  • mysql(命令行二进制)
  • mysqldump(命令行二进制)

The host that executes this module“ 是个远程主机

例如在 FreeBSD 中(作为远程主机)

$ pkg info | grep -i MySQLdb
py27-MySQLdb-1.2.5_1           Access a MySQL database through Python

FWIW,有一个未解决的问题需要 MySQL-python 模块 #906使用 Debian。
