配置MySQL主从复制报错
```
Last_IO_Error: Fatal error: The slave I/O thread stops because master and slave have equal MySQL server ids; these ids must be different for replication to work (or the --replicate-same-server-id option must be used on slave but this does not always make sense; please check the manual before using it).
```

修改配置文件 sudo vim /usr/my.cnf
当时配置从机的时候没改id,应该主机id是1,从机是2

然后重启MySQL服务
sudo service mysql restart
问题解决!
