★★★★★★★★★★★★★★★★★
在主库

show master status
+------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000001 | 2615 | | | 
+------------------+----------+--------------+------------------+

记录master_log_file和master_log_pos
在从库 ，
5004：
change master to

master_host='10.73.11.21',master_user='databus',master_password='databus', master_port=5000, master_log_file='mysql-bin.000001',master_log_pos=2615;

5005:
change master to master_host='10.73.11.21',master_user='databus',master_password='databus', master_port=5001, master_log_file='mysql-bin.000003',master_log_pos=389;
5006:
change master to master_host='10.73.11.21',master_user='databus',master_password='databus', master_port=5002, master_log_file='mysql-bin.000003',master_log_pos=389;
5007:
change master to master_host='10.73.11.21',master_user='databus',master_password='databus', master_port=5003, master_log_file='mysql-bin.000003',master_log_pos=389;

start slave;

show slave status\G;

注意一定要是
Slave_IO_Running: Yes
Slave_SQL_Running: Yes

查看Relay_Log_File: relay-bin.000002
在slave目录 tailf relay-bin.000002

在主库

CREATE TABLE test(i INT, c CHAR(10));
INSERT INTO test VALUES(1,'record one1111'),(2,'record 11111');

观察从库的log
