MySQL 8 :连接错误信息对应 这篇文章记录一下在 MacOS 的 Catalina 版本下使用 MacOS 下安装的 MySQL 8 在进行客户端连接时所碰到的问题。

mysql>
• MySQL 运行状态 liumiaocn:target liumiao$ mysql.server status
SUCCESS! MySQL running (4633)
liumiaocn:target liumiao$
问题现象 使用 MySQL Workbench 的如下配置
点击 Test Connection 时,提示如下错误信息
原因 MySQL 8 中的认证方式发生了变化
使用如下 SQL 即可确认当前 root 用户的认证方式:
mysql> SELECT Host, User, plugin from mysql.user;
+-----------+------------------+-----------------------+
| Host
| User
| plugin
|
+-----------+------------------+-----------------------+
| localhost | mysql.infoschema | mysql_native_password |
| localhost | mysql.session
| mysql_native_password |
| localhost | mysql.sys
| mysql_native_password |
| localhost | root
| caching_sha2_password |
+-----------+------------------+-----------------------+
4 rows in set (0.00 sec)
mysql>
对应方法 最简单的方式莫过于直接修改,比如使用如下 SQL 即可 mysql> ALTER USER "root"@"localhost" IDENTIFIED WITH mysql_native_password BY "liumiao123";
Query OK, 0 rows affected (0.03 sec)
mysql>
确认完之后再次确认结果 mysql> SELECT Host, User, plugin from mysql.user;
+-----------+------------------+-----------------------+
| Host
| User
| plugin
|
+-----------+------------------+-----------------------+
| localhost | mysql.infoschema | mysql_native_password |
| localhost | mysql.session
| mysql_native_password |
| localhost | mysql.sys
| mysql_native_password |
| localhost | root
| mysql_native_password |
+-----------+------------------+-----------------------+
4 rows in set (0.00 sec)
mysql>
当然,直接修改 MySQL 的配置文件,然后重新启动也可以设定成功,而且设定会持久保存。
[mysqld]
default_authentication_plugin=mysql_native_password
结果确认 此时使用 MySQL Workbench 再次连接,Test Connection 即可正常动作了。
正确输入上述修改的密码之后,即可显示连接成功了。
