在ubuntu上安装MySQL

我在安装MysqL时遇到问题，

这是我的MysqL部分

---
- name: Install MysqL
  apt:
    name: "{{ item }}"
  with_items:
    - python-MysqLdb
    - MysqL-server

- name: copy .my.cnf file with root password credentials
  template: 
    src: templates/root/.my.cnf
    dest: ~/.my.cnf
    owner: root
    mode: 0600

- name: Start the MysqL service
  service: 
    name: MysqL 
    state: started
    enabled: true

  # 'localhost' needs to be the last item for idempotency,see
  # http://ansible.cc/docs/modules.html#MysqL-user
- name: update MysqL root password for all root accounts
  MysqL_user: 
    name: root 
    host: "{{ item }}" 
    password: "{{ MysqL_root_password }}" 
    priv: "*.*:ALL,GRANT"
  with_items:
    - "{{ ansible_hostname }}"
    - 127.0.0.1
    - ::1
    - localhost

我有这个错误

Failed: [default] => (item=vagrant-ubuntu-trusty-64) => {"Failed": true,"item": "vagrant-ubuntu-trusty-64"}
msg: unable to connect to database,check login_user and login_password are correct or ~/.my.cnf has the credentials
Failed: [default] => (item=127.0.0.1) => {"Failed": true,"item": "127.0.0.1"}
msg: unable to connect to database,check login_user and login_password are correct or ~/.my.cnf has the credentials
Failed: [default] => (item=::1) => {"Failed": true,"item": "::1"}
msg: unable to connect to database,check login_user and login_password are correct or ~/.my.cnf has the credentials
Failed: [default] => (item=localhost) => {"Failed": true,"item": "localhost"}
msg: unable to connect to database,check login_user and login_password are correct or ~/.my.cnf has the credentials

我的.my.cnf是

[client]
user=root
password={{ MysqL_root_password }}

并在服务器上复制时

[client]
user=root
password=root

我不明白为什么，〜/ .my.cnf被创建

项目Github

谢谢

当MysqL-server无头安装时，没有密码。所以要使.my.cnf工作，它应该有一个空白的密码行。这是我测试一个.my.cnf：

[client]
user=root
password=

将.my.cnf放在您的流氓用户目录中，由root拥有，只能以root用户身份读取也很奇怪。

确认密码在.my.cnf中是空白的后，我能够在四个上下文中正确设置root密码。请注意，它之后无法运行，因为.my.cnf需要更新，所以它的幂等性测试失败。

有一个关于可执行的MysqL_user模块页面的注释，建议写入密码，然后写入.my.cnf文件。如果你这样做，你需要一个where子句到MysqL_user动作(可能在之前有一个文件stat)。

更优雅的是使用check_implicit_admin以及login_user和login_password。这是美丽的幂

作为第三种方式，也许check_implicit_admin使它更容易。

这是我的成功的手册显示上述，测试与几个新鲜的服务器。金达为此感到自豪。注意.my.cnf对于所有这些都是不必要的。

(编辑删除my.cnf)
