Ansible設置mysql root密碼

Question

你們中的任何一個人都有一個想法，建立一個MySQL的MySQL更新根密碼和授予特權？我已經創建了我的劇本，並在全新的安裝上按預期工作，沒有任何問題。但是當我再次進行流浪漢配置時，現在無法設置root密碼，並且出現錯誤。下面是我的代碼

mysql.yml

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

- name: drop database {{ dbname }} 
    mysql_db: 
    name: "{{ dbname }}" 
    login_user: "{{ dbuser }}" 
    login_password: "{{ dbpass }}" 
    state: absent 
    delegate_to: "{{ dbhost }}" 
    run_once: true 

- name: create database {{ dbname }} 
    mysql_db: 
    name: "{{ dbname }}" 
    login_user: "{{ dbuser }}" 
    login_password: "{{ dbpass }}" 
    state: present 
    delegate_to: "{{ dbhost }}" 
    run_once: true 

- name: ensure mysql is running and starts on boot 
    service: name=mysql state=started enabled=true 

- name: copy .my.cnf file with root password credentials 
    template: src=my.cnf.j2 dest=/root/.my.cnf owner=root mode=0600 

- name: update mysql root password for all root accounts "{{ dbpass }}" 
    mysql_user: name={{ dbuser }} host={{ item }} password="{{ dbpass }}" priv="{{ dbname }}.*:ALL,GRANT" 
    with_items: 
    - localhost 
    - 127.0.0.1 

- name: grant privilege on "{{ dbname }}" to "{{ dbuser }}" 
    mysql_user: 
    name: "{{ item.user }}" 
    host: "{{ item.host }}" 
    password: "{{ dbpass }}" 
    login_user: "{{ dbuser }}" 
    login_password: "{{ dbpass }}" 
    priv: "{{ dbname }}.*:ALL" 
    state: present 
    with_items: 
    - { user: "{{ dbuser }}" , host: localhost } 
    - { user: "{{ dbuser }}" , host: 127.0.0.1 } 
    delegate_to: "{{ dbhost }}" 
    run_once: true 

- name: ensure anonymous users are not in the database 
    mysql_user: name='' host={{ item }} state=absent 
    with_items: 
    - 127.0.0.1 
    - localhost 

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

my.cnf.j2

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

默認/ main.yml

--- 
dbhost: localhost 
dbname: mydb 
dbuser: root 
dbpass: root 

我能夠只是做一切如果它全新安裝但第二次運行它會給我錯誤

Answer 1

好像你更新.my.cnf與新密碼，您嘗試與下一個任務去改變它之前。

並且您可能想要在更新密碼時使用host_all選項，因爲with_items運行模塊多次，並且可能存在相同的錯誤：更改第一項上的密碼並且無法連接第二項。

已經找出了正確的答案。所以我會加我的答案只是對於那些和我一樣麻煩的人的參考
