mysql - "Plugin ' 0 ' is not loaded"

Question

将 MySQL 升级到新版本后，当我想连接到服务器时出现错误:

 ERROR 1524 (HY000): Plugin '0' is not loaded

有什么想法吗？

Answer 1

这看起来像是 MySQL 中的一个错误，如 Bug #60432 Modifying mysql.user table can deny users from logging in 。其中指出:

If database manager accidentally (or deliberately) modifies mysql.user table by adding any column in position lower (or equal) than "max_user_connections", then after reloading privileges no one is allowed to log in.

解决方法:撤消在 user 表中所做的修改。
