在ubuntu上用ansible安装MySQL

Question

我在使用ansible在流氓ubuntu上安装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被创建了

Github项目

谢谢

什么时候mysql-server无头安装,没有密码.因此,为了使.my.cnf工作,它应该有一个空白的密码行.这是我测试的一个.my.cnf:

[client]
user=root
password=

将.my.cnf您的vagrant用户目录放入root用户目录并且只能以root身份读取时,这也有点奇怪.

在确保密码为空后.my.cnf,我能够在这四个上下文中正确设置root密码.请注意,之后无法运行,因为.my.cnf需要更新,因此它无法进行幂等性测试.

在ansible mysql_user模块页面上有一个注释,建议写入密码然后编写.my.cnf文件.如果你这样做,你需要一个动作的where子句mysql_user(可能之前有一个文件stat).

更优雅是使用check_implicit_admin沿着login_user和login_password.这是非常幂等的.

作为第三种方式,也许check_implicit_admin使它更容易.

这是我成功的剧本,展示了上述内容,并使用一些新服务器进行了测试.有点为此感到自豪..my.cnf所有这些都不需要注意.

(编辑 - 删除my.cnf)

这是我完整的MySQL工作角色,可能对您有所帮助.

vars/main.yml:

mysql_root_pass: mypassword #MySQL Root Password

问/ main.yml:

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

 - name: Update MySQL root password for all root accounts
   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
   notify:
     - Restart MySQL

模板/ root.cnf.j2

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

处理器/ main.yml

---
 - name: Restart MySQL
   service: name=mysql state=restarted

site.yml

---
- hosts: all
  become: yes
  gather_facts: yes
  roles:
    - mysql
