Example Playbook

使用bin文件安装(已编译好的mysql,文件/opt/software/mysql-5.6.10-bin.tar.gz):
- hosts: node1
  roles:
   - { role: mysql }

源码安装:
- hosts: node1
  roles:
   - { role: mysql , mysql_install_from_source: true }

主从安装:
- hosts: node1
  roles:
   - { role: mysql, mysql_replication_role: 'master'}
   - { role: mysql, mysql_port: 3307, mysql_replication_role: 'slave', mysql_replication_master: '192.168.77.129'}

互为主备安装:
- hosts: node1
  roles:
   - { role: mysql, mysql_port: 3306, mysql_replication_role: 'master', auto_increment_offset: 1}
   - { role: mysql, mysql_port: 3307, mysql_replication_role: 'slave', mysql_replication_master: '192.168.77.129', auto_increment_offset: 2}
   - { role: mysql, mysql_port: 3307, mysql_replication_role: 'master' }
   - { role: mysql, mysql_port: 3306, mysql_replication_role: 'slave', mysql_replication_master: '192.168.77.129', mysql_replication_master_port: 3307}

使用

启动命令:/mysql_data/3306/mysql3306.sh start 关闭命令:/mysql_data/3306/mysql3306.sh stop
