ansible playbook出错：python mysqldb模块是必需的

我正在尝试通过将构建服务器中的wordpress实例部署到另一台主机服务器来教自己.两个服务器都是Ubuntu 16.04,一切正常,直到构建运行mysql tasks main.yml文件时,我得到以下错误：

“需要python mysqldb模块”

我在我的server / tasks / main.yml文件中包含了python-mysqldb,所以不确定错误是什么.有人能指出我正确的方向吗？

MySQL的/任务/ main.yml

---
# tasks file for mysql
- name: Create mysql database
  mysql_db: name={{ wp_mysql_db }} state=present

- name: Create mysql user
  mysql_user:
    name={{ wp_mysql_user }}
    password={{ wp_mysql_password }}
    priv=*.*:ALL

服务器/任务/ main.yml

---
# tasks file for server
- name: Update apt cache
  apt: update_cache=yes cache_valid_time=3600
  sudo: yes

- name: Install required software
  apt: name={{ item }} state=present
  sudo: yes
  with_items:
    - apache2
    - python-mysqldb
    - mysql-server
    - mysql-client
    - php7.0
    - php7.0-mysql
    - libapache2-mod-php7.0
    - php7.0-cli
    - php7.0-cgi
    - php7.0-gd
    - php7.0-mcrypt

运行时出现控制台输出错误：ansible-playbook playbook.yml -i hosts -u jbloggs -K

TASK [mysql : Create mysql database] *******************************************
task path: /etc/ansible/roles/mysql/tasks/main.yml:3
fatal: [wordpress1]: FAILED! => {"changed": false, "failed": true, "msg": "the python mysqldb module is required"}

解决方法:

您可以按要求安装它：

- name: Install required software
  apt: name={{ item }} state=present
  sudo: yes
  with_items:
    - apache2
    - build-essential
    - python-dev
    - libmysqlclient-dev
    - python-mysqldb
    - mysql-server
    - mysql-client
    - php7.0
    - php7.0-mysql
    - libapache2-mod-php7.0
    - php7.0-cli
    - php7.0-cgi
    - php7.0-gd
    - php7.0-mcrypt

如果这不起作用,那么你可以这样做：

- name: Install required software
  apt: name={{ item }} state=present
  sudo: yes
  with_items:
    - apache2
    - build-essential
    - python-dev
    - libmysqlclient-dev
    - python-pip
    - mysql-server
    - mysql-client
    - php7.0
    - php7.0-mysql
    - libapache2-mod-php7.0
    - php7.0-cli
    - php7.0-cgi
    - php7.0-gd
    - php7.0-mcrypt

- name: Install the MySQL-python through pip
  sudo: yes
  pip:
    name: "{{ item }}"
    state: forcereinstall
  with_items:
    - pip
    - MySQL-python
