使用MySQL 5.7.24版本的安裝文件替換MySQL 5.7.19版本的安裝文件,數據庫復制頻繁中斷,查看error日志發現下面錯誤:
[Warning] InnoDB: Table mysql/innodb_index_stats has length mismatch in the column name table_name. Please run mysql_upgrade
解決辦法:
在MySQL服務正常運行的狀態下,使用mysql_upgrade命令進行處理:
mysql_upgrade --host='127.0.0.1' --port=3358 --user='root' --password="password"
執行結果:
mysql_upgrade: [Warning] Using a password on the command line interface can be insecure. Checking if update is needed. Checking server version. Running queries to upgrade MySQL server.
