MySQL不会让用户登录:错误1524

Question

Server version: 5.7.10 MySQL Community Server (GPL)

在MySQL中,我有一个用户芒果.用户在创建它时工​​作得很好.但是,重新启动计算机后,尝试登录芒果会产生以下输出:

$ mysql -u mangos -p
Enter password: 
ERROR 1524 (HY000): Plugin '*some_random_long_hash_I_cannot_remember' is not loaded
$ 

它让我想起了密码哈希,所以在调查mysql.user后,我发现芒果没有密码!我更新了密码:

SET PASSWORD FOR 'mangos'@'127.0.0.1' = PASSWORD('mangos');
FLUSH PRIVILEGES;

现在,我得到:

ERROR 1524 (HY000): Plugin '*3FBBDB84EA2B2A0EA599948396AD622B7FF68183' is not loaded

3FBBDB84EA2B2A0EA599948396AD622B7FF68183与mysql的用户密码列中显示的数字相同,是一个与原始数字不同的数字.我还是无法登录.

如何让MySQL正确识别密码？这甚至是问题吗？

您的用户表似乎已损坏.可能你提到的重启会触发升级到MySQL并且mysql_upgrade脚本没有运行.这应该解决这种情况:

mysql_upgrade -u root -ppassword --skip-grant-tables
mysql -u root -ppassword -e "UPDATE mysql.user SET plugin = 'mysql_native_password' WHERE user = 'mangos'; FLUSH PRIVILEGES"

即使已经完成升级,也提供重新应用升级脚本的--force选项mysql_upgrade.在从备份中部分恢复的情况下可能需要这样做.

另外值得一提的是,更改用户密码的命令在MySQL 5.7.6/MariaDB 10.2.0中已更改并转发:

ALTER USER mangos IDENTIFIED BY 'mangos';

现在,这是设置密码的首选方法,尽管旧SET PASSWORD语法尚未正式弃用.
