我已经在MySQL主服务器上设置了proxysql，以便进行读写拆分。MySQL主站和从站，proxysql服务器正在运行，但是我在proxysql终端上发现了一个Access denied错误。

[devops@DRMBUST05 ~]$ mysql -uproxysql -p**** -h 127.0.0.1 -P 6033
mysql: [Warning] Using a password on the command line interface can be insecure.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> show databases;

这是proxysql.log

我确信我可以用proxysql中配置的用户名和密码连接到MySQL主站和从站，如下所示：

[devops@DRMBUST05 ~]$ mysql -u proxysql -h 127.0.0.1 --port 33003 -p
Enter password:

这是因为我在MySQL主机上安装了proxysql吗？有人知道怎么回事吗？任何提示都将不胜感激。

ProxySQL不支持引入MySQL 8的caching_sha2_password。

你要么需要：

在proxysql中设置admin-hash_passwords=false，或
将MySQL中该用户的身份验证机制更改为mysql_native_password。(旧的身份验证机制)。
