我遇到连接MySQL实例的问题，并决定将root插件从caching_sha2_password更改为mysql_native_password
即
mysql> select host,user, account_locked, plugin from mysql.user;
+-----------+------------------+----------------+-----------------------+
| host | user | account_locked | plugin |
+-----------+------------------+----------------+-----------------------+
| % | root | N | caching_sha2_password |
| localhost | mysql.infoschema | Y | mysql_native_password |
| localhost | mysql.session | Y | mysql_native_password |
| localhost | mysql.sys | Y | mysql_native_password |
| localhost | root | N | caching_sha2_password |
+-----------+------------------+----------------+-----------------------+
5 rows in set (0.00 sec)
mysql> update mysql.user set plugin = 'mysql_native_password' where user = 'root'
-> ;
Query OK, 2 rows affected (0.04 sec)
Rows matched: 2 Changed: 2 Warnings: 0
mysql> select host,user, account_locked, plugin from mysql.user;
+-----------+------------------+----------------+-----------------------+
| host | user | account_locked | plugin |
+-----------+------------------+----------------+-----------------------+
| % | root | N | mysql_native_password |
| localhost | mysql.infoschema | Y | mysql_native_password |
| localhost | mysql.session | Y | mysql_native_password |
| localhost | mysql.sys | Y | mysql_native_password |
| localhost | root | N | mysql_native_password |
+-----------+------------------+----------------+-----------------------+
我重新启动了实例，现在我无法登录！
bitnami@bit2:~$ mysql -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
是否有将root密码插件更改回caching_sha2_password？
使用mysql_native_password
