在ubuntu上安装带有ansible的MySQL

我在一个流浪的ubuntu上安装带有ansible的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.我的.cnf是

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

当复制到服务器上时

[client]
user=root
password=root

我不明白为什么会创建~/.my.cnf

计划

谢谢

当

mysql服务器

无头安装时，没有密码。因此，要使

.my.cnf

工作，它应该有一个空白密码行。以下是我对

.my.cnf

的测试：

[client]
user=root
password=

将

.my.cnf

放在您的

vagrant

用户目录中也有点奇怪，它由root所有，并且只能作为root读取

在确保

.my.cnf

中的密码为空后，我能够在这四个上下文中为root用户正确设置密码。请注意，此后它将无法运行，因为需要更新

.my.cnf

，因此它无法通过幂等性测试

ansible mysql_用户模块页面上有一条提示，建议先写密码，然后写

.my.cnf

文件。如果这样做，您需要一个

where

子句来执行

mysql\u用户

操作（可能在此之前有一个文件stat）

更优雅的是使用

check\u implicit\u admin

以及

login\u user

和

login\u password

。这是美丽的幂等式

作为第三种方法，也许

check\u implicit\u admin

更容易实现

下面是我成功的剧本，展示了以上内容，并用几个新服务器进行了测试。有点自豪。注意：所有这些都不需要.my.cnf

（编辑-删除my.cnf）

这是我完整的MySQL工作角色，可能会对您有所帮助

变量/main.yml：

mysql_root_pass: mypassword #MySQL Root Password

 - name: Install the MySQL packages
   apt: name={{ item }} state=installed update_cache=yes
   with_items:
     - mysql-server-5.6

     - libmysqlclient-dev

   mysql_user: name=root host={{ item }} password={{ mysql_root_pass }} state=present
   with_items:
     - "{{ ansible_hostname }}"
     - 127.0.0.1
     - ::1
     - localhost

 - name: Copy the root credentials as .my.cnf file
   template: src=root.cnf.j2 dest=~/.my.cnf mode=0600

 - name: Ensure Anonymous user(s) are not in the database
   mysql_user: name='' host={{ item }} state=absent
   with_items:
     - localhost
     - "{{ ansible_hostname }}"

 - name: Remove the test database
   mysql_db: name=test state=absent

询问/main.yml：

模板/root.cnf.j2

如果您需要任何帮助，请查看此github。感谢ubuntu 20.04，现在需要登录unix套接字：

- name: setting default root password
  mysql_user:
    name: root
    password: "{{ mysql_root_password }}"
    check_implicit_admin: true
    login_unix_socket: /var/run/mysqld/mysqld.sock

干杯

@ant您是在尝试新服务器还是在部分安装完成的服务器上？如果是后者，请确保

.my.cnf

不存在，然后手动验证根密码。我正在执行vagrant Provision对吗，您是否

vagrant销毁了它？您是否删除了
.my.cnf
？您是否手动验证了根密码？请尝试删除上例中带有
login\u user
和
login\u password
行的字符串。由此看来，如果指定了凭据，则即使在上述工作手册中的ansible、s/sudo/Been\u user/g的当前版本中使用
check\u implicit\u admin=yes
，也会使用这些凭据！
