1.首先初始化两个库
[mysql@localhost ~]$ cat initdb.info
#IP SOFT_DIR INSTANCE_BASE_DIR INSTANCE_NAME_PREFIX INSTANCE_NAME INSTANCE_PORT SERVER_ID ADMIN_USER ADMIN_PASSWD
192.168.80.154 /usr/local/mysql-5.7.23/ /home/mysql/mysqldb db master 45678 4567801 root oracle
192.168.80.154 /usr/local/mysql-5.7.23/ /home/mysql/mysqldb db slave 34567 3456701 root oracle
#192.168.80.154 /usr/local/mysql-5.7.23/ /home/mysql/mysqldb db slave01 33344 3334401 root oracle
[mysql@localhost ~]$ sh init57_v1.3_20180402.sh
2.主库创建用户
create user master@'%' identified by 'oracle';
grant all privileges on *.* to master@’%‘；
3.从库中执行命令
CHANGE MASTER TO MASTER_HOST='192.168.80.154',MASTER_USER='master',MASTER_PASSWORD='oracle',MASTER_PORT=45678,MASTER_AUTO_POSITION=1;
4.从库中执行start slave；
查看是否主从连接完成
show slave status；显示两个yes即为成功
mysql> show slave statusG

5.主库中创建库添加数据验证从库中是否增加数据
主库中
mysql> create database test;
Query OK, 1 row affected (0.01 sec)
mysql> use test;
Database changed
mysql> create table t1(x int not null auto_increment primary key);
Query OK, 0 rows affected (0.05 sec)
mysql> ^C
mysql> ^C
mysql> insert into t1 values();
Query OK, 1 row affected (0.18 sec)
mysql> insert into t1 values();
Query OK, 1 row affected (0.01 sec)
mysql> insert into t1 values();
Query OK, 1 row affected (0.01 sec)
从库中
mysql> select @@port;
+--------+
| @@port |
+--------+

1 row in set (0.00 sec)
mysql> use test;
