Mysql主從複製報錯處理 Last

前幾天，手動搭建一個mysql主從複製集群,今天在執行過程中，出現如下錯誤：Error 'Can't drop database 'test'; database doesn't exist' on query. Default database: 'test'. Query: 'drop database test'。

執行命令：show slave status

<code>mysql> show slave status\\G;

解決方法：

由於上面提示錯誤，沒有測試數據庫。可以手動建一個test數據庫

stop slave;

create database test;

start slave;

<code>mysql> show slave status\\G;
