MySql指定为定义者的用户('mysql.infoschema'@'localhost')不存在
MySql The user specified as a definer ('mysql.infoschema'@'localhost') does not exist
我试图通过运行宁此命令
列出所有数据库
mysql> show databases;
并出现以下错误：-
ERROR 1449 (HY000): The user specified as a definer ('mysql.infoschema'@'localhost') does not exist
然后我尝试创建用户
mysql> create user 'mysql.infoschema'@'localhost' IDENTIFIED BY 'password';
出现以下错误：-
ERROR 1726 (HY000): Storage engine 'MyISAM' does not support system tables. [mysql.user]
为了解决这个问题，我 运行 mysqld --upgrade=FORCE 但出现错误
[ERROR] [MY-010123] [Server] Fatal error: Please read "Security" section of the manual to find out how to run mysqld as root!
然后我 运行 mysqld --user=root 它成功了。但没有任何输出消息
我仍然无法列出所有数据库或使用 dbeaver-cs 工具连接 mysql 服务器。
所有站点都正常运行 运行ning，没有任何问题。
mysql Ver 8.0.26 for Linux on x86_64（源分发）
OS- centos
通常在进行迁移或备份时，问题可能出在 mysql 数据库中。
备份数据库时不应使用任何 information_schema, mysql,sys and performance_schema 数据库。
如果用户很重要可以插入。
从旧服务器转储 users table 的 mysql 数据库。
您会发现新服务器上可能有 4 个默认用户，您应该从插入语句中删除这些用户。
然后从转储中复制插入语句，use mysql 在新的服务器数据库上并插入它。
如果新服务器是 MySQL 8+ 而旧服务器是 5.xx 您会发现缺少列，只需将其作为空列添加到插入语句中即可。
最后 6 列您应该添加到插页中。
