④、查看 bin-log 文件
mysql> show master status;
+------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000001 | 396 | | |
+------------------+----------+--------------+------------------+
1 row in set (0.00 sec)
⑤、连接主数据库
mysql> change master to master_host='192.168.1.117',master_user='tongbu',master_password='123456',master_log_file='mysql-bin.000001',master_log_pos=396;
Query OK, 0 rows affected (0.27 sec)
⑥、启动同步，查看主从集群是否创建完成
mysql> slave start;
Query OK, 0 rows affected (0.00 sec)
mysql> show slave status \G
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
当前如果 Slave_IO_Running 进程和 Slave_SQL_Running 进程都是yes，就代表主从同步建立完成。
5、建立主从同步[192.168.1.118主]
