Example Playbook

默认安装, 使用bin文件(已编译好的mysql),文件路径/opt/software/mysql-boost-5.7.20-bin.tar.gz)：
- hosts: node2
  roles:
  - mysql57

源码编译安装
- hosts: node2
  roles:
  - { role: mysql57, mysql57_install_from_source: true }
  
指定端口
- hosts: node2
  roles:
  - { role: mysql57, mysql57_port: "3307" }

默认使用gitd方式配置主从
- hosts: node2
  roles:
  - { role: mysql57, mysql57_replication_role: 'master'}
  - { role: mysql57, mysql57_port: 3307, mysql57_replication_role: 'slave', mysql57_replication_master: '192.168.77.130'}

采用file方式配置主从
- hosts: node2
  vars:
  - mysql57_replication_mode: 'file' # 指定binlog方式为file pos
  roles:
  - { role: mysql57, mysql57_replication_role: 'master'}
  - { role: mysql57, mysql57_port: 3307, mysql57_replication_role: 'slave', mysql57_replication_master: '192.168.77.130'}

主主配置
- hosts: node2
  roles:
  - role: 'mysql57'
    mysql57_port: '3306'
    mysql57_replication_role: 'master'
    mysql57_replication_user: {name: 'rep_3306', password: '123456'}

  - role: 'mysql57'
    mysql57_port: '3307'
    mysql57_replication_role: 'master'
    mysql57_replication_user: {name: 'rep_3307', password: '123456'}
    
  - role: 'mysql57'
    mysql57_port: '3306'
    mysql57_auto_increment_offset: '1'
    mysql57_auto_increment_increment: '2'
    mysql57_replication_role: 'slave' # 指定为slave角色
    mysql57_replication_master: '192.168.77.130'
    mysql57_replication_master_port: '3307'
    mysql57_replication_user: {name: 'rep_3307', password: '123456'}

  - role: 'mysql57'
    mysql57_port: '3307'
    mysql57_auto_increment_offset: '2'
    mysql57_auto_increment_increment: '2'
    mysql57_replication_role: 'slave'
    mysql57_replication_master: '192.168.77.130'
    mysql57_replication_master_port: '3306'
    mysql57_replication_user: {name: 'rep_3306', password: '123456'}

多源复制
- hosts: node2
  roles:
  - role: 'mysql57'
    mysql57_port: '3306' 
    mysql57_binlog_format: 'mixed'
    mysql57_auto_increment_offset: '1'
    mysql57_auto_increment_increment: '2'
    mysql57_replication_role: 'master'
    mysql57_replication_user: {name: 'rep_3306', password: '123456'}

  - role: 'mysql57'
    mysql57_port: '3307'
    mysql57_binlog_format: 'mixed'
    mysql57_auto_increment_offset: '2'
    mysql57_auto_increment_increment: '2'
    mysql57_replication_role: 'master'
    mysql57_replication_user: {name: 'rep_3307', password: '123456'}
    
  - role: 'mysql57'
    mysql57_port: '3308'
    mysql57_replication_role: 'slave'
    mysql57_replication_channel:  # 指定通道链接
    - master_host: "192.168.77.130"
      master_port: "3306"
      master_user: "rep_3306"
      master_password: "123456"
    - master_host: "192.168.77.130"
      master_port: "3307"
      master_user: "rep_3307"
      master_password: "123456" 
    
组复制
- hosts: node2
  vars:
  - mysql57_replication_ga: true  # 开启组复制
  - mysql57_replication_role: 'master' # 指定为master角色
  - mysql57_group_replication_group_name: "aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa"  # 指定组名
  - mysql57_group_replication_group_seeds: "192.168.77.130:24901,192.168.77.130:24902,192.168.77.130:24903" # 指定组内的成员
  - mysql57_replication_user: {name: 'rep', password: '123456'} # 指定用于复制的账号
  - ipnames:  # 指定ip和主机名的对应关系，这里使用单机多实例。
     '192.168.77.130': 'node2'

  roles:
  - role: 'mysql57'
    mysql57_port: '3306'  
    mysql57_group_recation_local_address: "192.168.77.130:24901"  # 指定组监听地址
    mysql57_replication_ga_first: true # 指定组内第一成员

  - role: 'mysql57'
    mysql57_port: '3307'
    mysql57_group_recation_local_address: "192.168.77.130:24902"
    
  - role: 'mysql57'
    mysql57_port: '3308'
    mysql57_group_recation_local_address: "192.168.77.130:24903"
