我最近将我的流浪汉从ubuntu / trusty-64升级到了bento / ubuntu-16.04.随着MySQL更新到5.7.我已经对我的剧本进行了几次更新,但在设置root用户的密码时我一直遇到困难.

在过去(5.7之前),以下就足够了：

- name: MySQL | Set the root password.
  mysql_user: 
    name=root 
    host=localhost
    password={{ mysql_root_password }}
  become: true

在我的剧本中,这是通过尝试删除匿名用户来测试的.

- name: MySQL | Delete anonymous MySQL server user for {{ server_hostname }}
  mysql_user: 
    name="" 
    host="{{ server_hostname }}" 
    state="absent" 
    login_user=root 
    login_password={{ mysql_root_password }}

但是,现在我的剧本在这一步失败了,返回：

“Access denied for user ‘root’@’localhost'”

TASK [mysql : MySQL | Delete anonymous MySQL server user for vagrant] **********
task path: /Users/jonrobinson/vagrant/survey/playbooks/roles/mysql/tasks/mysql.yml:51
fatal: [vagrant]: FAILED! => {"changed": false, "failed": true, "msg": "unable to connect to database, check login_user and login_password are correct or /home/vagrant/.my.cnf has the credentials. Exception message: (1698, \"Access denied for user 'root'@'localhost'\")"}

我尝试了几件事：

>为root用户设置密码空白mysql_root_password =“”
>尝试删除root用户,然后使用Ansible重新创建它.我得到相同的错误可能是因为它试图在root用户处理.
>手动更新mysql中的root密码. – 除非我删除root用户并使用所有权限重新创建root用户,否则这似乎也不起作用(密码无法识别).只是更新root用户密码似乎没有变化.

我的完整MySQL YAML：

- name: MySQL | Delete anonymous MySQL server user for localhost
  mysql_user: name="" state="absent" host=localhost login_user=root login_password={{ mysql_root_password }}

- name: MySQL | Secure the MySQL root user for IPV6 localhost (::1)
  mysql_user: name="root" password="{{ mysql_root_password }}" host="::1" login_user=root login_password={{ mysql_root_password }}

- name: MySQL | Secure the MySQL root user for IPV4 localhost (127.0.0.1)
  mysql_user: name="root" password="{{ mysql_root_password }}" host="127.0.0.1" login_user=root login_password={{ mysql_root_password }}

- name: MySQL | Secure the MySQL root user for localhost domain (localhost)
  mysql_user: name="root" password="{{ mysql_root_password }}" host="localhost" login_user=root login_password={{ mysql_root_password }}

- name: MySQL | Secure the MySQL root user for {{ server_hostname }} domain
  mysql_user: name="root" password="{{ mysql_root_password }}" host="{{ server_hostname }}" login_user=root login_password={{ mysql_root_password }}

- name: MySQL | Remove the MySQL test database
  mysql_db: db=test state=absent login_user=root login_password={{ mysql_root_password }}

- name: MySQL | create application database user
  mysql_user: name={{ dbuser }} password={{ dbpass }} priv=*.*:ALL host='%' state=present login_password={{ mysql_root_password }} login_user=root

- name: MySQL | restart mysql
  service: name=mysql state=restarted
  become: true

最佳答案:

我弄清楚了.当没有提供密码时,问题的要点与使用auth_socket的root用户的mysql 5.7有关.请参阅以下内容：“That plugin doesn’t care and doesn’t need a password. It just checks if the user is connecting using a UNIX socket and then compares the username.”

在这种情况下,您无法使用以下方法更新密码：

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('test');

而必须使用：

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password='test';

解决方案1：但是,Ansible,从版本2.0.2开始没有考虑到这一点.我可以通过在安装MySql之前设置密码来解决这个问题

- name: Specify MySQL root password before installing
  debconf: name='mysql-server' question='mysql-server/root_password' value='{{mysql_root_password | quote}}' vtype='password'
  become: true

- name: Confirm MySQL root password before installing
  debconf: name='mysql-server' question='mysql-server/root_password_again' value='{{mysql_root_password | quote}}' vtype='password'
  become: true

- name: MySQL | install mysql packages
  apt: pkg={{ item }} state=installed
  become: true
  with_items:    
   - mysql-client
   - mysql-common
   - mysql-server
   - python-mysqldb
  ...

However, this has also since been addressed by Ansible

解决方案2：最简单的解决方案是将Ansible升级到2.2.1
