MySQL不允许用户登录:错误1524 [英] MySQL Won't let User Login: Error 1524

问题描述

Server version: 5.7.10 MySQL Community Server (GPL)

在MySQL中，我有一个用户芒果.当我创建它时，用户可以完美地工作.但是，重新启动计算机后，尝试登录芒果会产生以下输出:

In MySQL, I have a user mangos. The user worked perfectly when I created it. After rebooting my computer, though, attempting to login to mangos yielded this output:

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

这让我想起了密码哈希，因此在调查mysql.user之后，我发现mangos没有密码！ 我更新了密码:

It kind of reminded me of a password hash, so after investigating mysql.user, I found that mangos had no password! I updated the password:

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

现在，我得到了:

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

3FBBDB84EA2B2A0EA599948396AD622B7FF68183是与mysql.user的password列中显示的mangos相同的数字，并且与原始数字不同.我仍然无法登录.

3FBBDB84EA2B2A0EA599948396AD622B7FF68183 is the same number shown in the password column of mysql.user for mangos, and is a different number than originally. I still can't log in.

如何使MySQL正确识别密码?这甚至是问题所在吗?

How do I make MySQL recognize a password properly? Is that even the issue here?

推荐答案

看来您的用户表已损坏.您提到的重启可能触发了MySQL升级，并且mysql_upgrade脚本未运行.这应该可以解决这种情况:

It appears your user table is corrupted. Likely the reboot you mentioned triggered an upgrade to MySQL and the mysql_upgrade script was not run. This should resolve the situation:

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"

为mysql_upgrade提供--force选项将重新应用升级脚本，即使升级已经完成.如果要从备份中进行部分还原，则可能需要这样做.

Providing the --force option to mysql_upgrade will re-apply the upgrade scripts even if an upgrade has already been done. This may be needed in case of partial restoration from backup.

还值得一提的是， MariaDB 10.2.0 并转发:

Also worth mentioning, the command to change a user password has changed in MySQL 5.7.6 / MariaDB 10.2.0 and forward:

ALTER USER mangos IDENTIFIED BY 'mangos';

这是设置密码的首选方法，尽管旧的SET PASSWORD语法并未正式弃用.

This is now the preferred method for setting the password, although the older SET PASSWORD syntax is not officially deprecated.
