MySQL8.0 caching_sha2_password報錯問題

在bin目錄下執行mysql -uroot -p123456

登錄后執行：

use mysql;

select host, user, plugin from user;

 

打印：

+-----------+------------------+-----------------------+
| host | user | plugin |
+-----------+------------------+-----------------------+
| localhost | mysql.infoschema | caching_sha2_password |
| localhost | mysql.session | caching_sha2_password |
| localhost | mysql.sys | caching_sha2_password |
| localhost | root | caching_sha2_password |
+-----------+------------------+-----------------------+
4 rows in set (0.00 sec)

發現新版MySQL都是默認用caching_sha2_password這個plugin來加密密碼了，HeidiSQL無法接入。現改成原生密碼的加密方式。

 

執行：

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';
 
flush privileges;

 

就可以了。再執行上面的查詢語句，返回：

+-----------+------------------+-----------------------+
| host | user | plugin |
+-----------+------------------+-----------------------+
| localhost | mysql.infoschema | caching_sha2_password |
| localhost | mysql.session | caching_sha2_password |
| localhost | mysql.sys | caching_sha2_password |
| localhost | root | mysql_native_password |
+-----------+------------------+-----------------------+
4 rows in set (0.00 sec)

可知，已經改mysql_native_password插件了。
