可能な設定mysqlのルートのパスワード

Question

あなたはmysqlのrootパスワードの更新と権限の付与のためのymlを構築するアイデアがありますか？私は自分の作ったプレイブックを新鮮にインストールしても、期待通りに動作し、全く問題はありません。しかし、私が不規則なプロビジョニングをやり直すと、ルートパスワードを設定することができなくなり、エラーが発生します。以下は、私は全力を尽くすことができるよ私のコード

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 }} 

デフォルト/ main.yml

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

ですその新鮮なインストールがうまくいけば、2回目に実行すると、以下のエラーが表示されます

Answer 1

あなたは次のタスクでそれを変更しようとする直前に新しいパスワードで.my.cnfを更新するように思えます。

with_itemsはモジュールを複数回実行するので、パスワードを更新するときにhost_allオプションを使用し、同じエラーが発生する可能性があります。最初のアイテムのパスワードを変更し、2番目のアイテムを接続できません。
