配置mysql_master

mysql> change master to master_host='192.168.1.139',master_user='slave',master_password='slave',master_log_file='slave-log.000001',master_port=3307, master_log_pos=1460;
Query OK, 0 rows affected, 2 warnings (1.17 sec)

mysql> change master to master_host='192.168.1.139',master_user='slave',master_password='slave',master_auto_position=1,get_master_public_key=1;
Query OK, 0 rows affected, 2 warnings (0.45 sec)

配置mysql_slave

mysql> change master to master_host='192.168.1.108',master_user='slave',master_password='slave',master_log_file='master-log.000001',master_port=3307, master_log_pos=156;
Query OK, 0 rows affected, 2 warnings (0.15 sec)

mysql> change master to master_host='192.168.1.108',master_user='slave',master_password='slave',master_auto_position=1,get_master_public_key=1;
Query OK, 0 rows affected, 2 warnings (0.14 sec)

开启复制

mysql_master上start slave
mysql> start slave;
Query OK, 0 rows affected, 1 warning (0.00 sec)

查看slave status,发现并没有成功启动复制。出现错误 Access denied for user 'slave'@'172.17.0.1' (using password: YES) 需要到mysql_slave上创建响应的用户和权限，

mysql> show slave status \G;

测试复制
mysql_slave上创建test_db_slave

Query OK, 1 row affected (0.01 sec)

mysql_master上创建test_db_master

mysql> CREATE DATABASE test_db_master;
Query OK, 1 row affected (0.24 sec)

查看mysql_slave上的databases
