Vagrant Ansible CentOS 7如何安裝MySQL 5.7並更改默認密碼

Question

我在CentOS 7上使用Vagrant和Ansble。 我試圖安裝MySQL 5.7，但在嘗試更新MySQL密碼時遇到問題。

- name: Install MySQL 5.7 repo 
    yum: name=http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm state=present 

- name: Install MySQL 5.7 
    yum: pkg={{ item }} 
    with_items: 
    - mysql-community-server 
    - MySQL-python 

- name: Start the MySQL service 
    service: name=mysqld state=started enabled=true 

- name: update mysql root passwd 
    mysql_user: name=root 
      host={{ item }} 
      password='PassW0rd' 
      check_implicit_admin=yes 
      login_user=root 
      login_password='' 
      state=present 
    with_items: 
    - 127.0.0.1 
    - ::1 
    - localhost 

我研究發現MySQL 5.7自動生成默認密碼，所以我的腳本失敗了。有人會幫我解決這個問題嗎？
