A机先搞一下
GRANT REPLICATION SLAVE ON *.* TO 'root' @'%' IDENTIFIED BY '';
mysql> flush privileges;
mysql> show master status;
记录下position的值
B机也搞一下
GRANT REPLICATION SLAVE ON *.* TO 'root' @'%' IDENTIFIED BY '';
mysql> flush privileges;
mysql> show master status;
也记录position的值
然后
A 机B机相互授权
B机
CHANGE MASTER TO MASTER_HOST='172.16.108.71',MASTER_USER='root',MASTER_PASSWORD='',MASTER_LOG_FILE='mysql-bin.000005',MASTER_LOG_POS=235;
START SLAVE;
A机
CHANGE MASTER TO MASTER_HOST='172.16.108.72',MASTER_USER='root',MASTER_PASSWORD='',MASTER_LOG_FILE='mysql-bin.000011',MASTER_LOG_POS=430;
START SLAVE;
然后测试增删改查
