Question

两个星期以来，我一直在使用Ansible进行MySQL部署和工作。我必须在LV上安装MySQL。

在MySQL部署之前，Ansible脚本会创建/var/lib/mysql，LV并将其安装在/var/lib/mysql上。然后，它创建MySQL用户和MySQL组以在MySQL目录上设置0700。完成后，Ansible部署MySQL 5.7。

我的Ansible代码的一部分：

- name: "Group : mysql"
  group:
    name: "mysql"
    state: "present"
  tags:
    - User mysql

- name: "user : mysql"
  user:
    name: "mysql"
    shell: "mysql"
    group: "mysql"
    createhome: "no"
    append: "True"
    state: "present"
  tags:
    - User

- name: "Set rights on mysql dir "
  file:
    path: "/var/lib/mysql"
    owner: "mysql"
    group: "mysql"
    mode: 0700
  tags:
    - mysql dir rights

- name: "mysql root password"
  debconf:
    name: "mysql-server"
    question: "mysql-server/root_password"
    value: "{{ password_root_mysql }}"
    vtype: "password"
  when: password_root_mysql is defined
  tags:
    - Install  

- name: "mysql root password confirmation"
  debconf:
    name: "mysql-server"
    question: "mysql-server/root_password_again"
    value: "{{ password_root_mysql }}"
    vtype: "password"
  when: password_root_mysql is defined
  tags:
    - Install mysql

- name: "Install : MySQL Server"
  apt:
    update_cache: "True"
    name: "mysql-server"
    install_recommends: "True"
  tags:
    - Install mysql
  notify:
    - stop mysql   

- name: "Copie du template root.cnf.j2 vers root/.my.cnf "
  template:
    src: "{{ mysql_template_rootcnf }}"
    dest: "~/.my.cnf"
    owner: "root"
    mode: "0600"
  tags:
    - Install mysql

因此，当我尝试在没有任何LV和目录设置的情况下安装mysql-server时，它将起作用。但是，当我准备具有良好权限的目录MySQL时，无论是手动部署还是自动部署，安装都无法进行。

有什么想法吗？

Ubuntu 16.04和MYSQL 5.7。 Ansible v2.7

好吧，我发现了问题，/ var / lib / mysql（在lv挂载在其中）的Lost + Found目录被认为像数据库一样，mysql不喜欢它。在我的代码中，我刚刚添加了

- name: "Remove lost+found from {{ mysql_dir }}"
  file: 
    path: "{{ mysql_dir }}/lost+found"  
    state: absent

在/ var / lib / mysql上安装的lv上安装mysql-server 5.7
