配置MySQL主從復制報錯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

配置MySQL主從復制報錯 ``` 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
  當時配置從機的時候沒改id，應該主機id是1，從機是2

  然后重啟MySQL服務

sudo service mysql restart

  問題解決!
