在bin目录下执行mysql -uroot -p123456
登录后执行:
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)
发现新版MySQL都是默认用caching_sha2_password这个plugin来加密密码了,HeidiSQL无法接入。现改成原生密码的加密方式。
执行:
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';
flush privileges;
就可以了。再执行上面的查询语句,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,已经改mysql_native_password插件了。
