MySQL Error--InnoDB Table mysqlinnodb_index_stats has length mismatch in the column

使用MySQL 5.7.24版本的安装文件替换MySQL 5.7.19版本的安装文件，数据库复制频繁中断，查看error日志发现下面错误：

[Warning] InnoDB: Table mysql/innodb_index_stats has length mismatch in the column name table_name. Please run mysql_upgrade

解决办法：

在MySQL服务正常运行的状态下，使用mysql_upgrade命令进行处理：

mysql_upgrade --host=‘127.0.0.1‘ --port=3358 --user=‘root‘ --password="password"

执行结果：
