1、主库

设置my.cnf

server_id = 2 必须唯一

binlog-do-db = abo-assist 备份的数据库

log-bin=mysql-bin 开启binlog

创建同步账号并授权

grant replication slave on *.* to 'replication'@'%' identified by '123456';

2、从库

server_id = 10 必须唯一

3、开启主从同步（从库上操作）

mysql> stop slave;

mysql>change master to master_host='192.168.190.131',master_user='replication',master_password='123456',master_port=3336,master_log_file='mysql-bin.000002',master_log_pos=120;

mysql> start slave;

备注

清除从库日志

mysql>show slave status\G （查看从库备份状态）

mysql>reset master

mysql访问外部地址

myql -h -u -p
