WAMP 服务器 PhpMyAdmin 未使用有效凭据进行身份验证

Question

WAMP server MySQL is working fine in CLI. But PHPMyAdmin is not working . I had MySQL and workbench installed with 3306 port (before I install the WAMP server). This is why My WAMP server MySQL wasn't working, I changed the port to 3309 in MySQL my.ini file, it's working fine in CLI but not working in PHPMyAdmin.

I have already tried alter user 'username'@'localhost' identified with mysql_native_password by 'password'; still not working in with PHPMyAdmin but CLI. I don't want to downgrade my MySQL version.

MySQL Version 8.0.21

ERROR:

Answer 1

Search for libraries/config.default.php

and change

$cfg['Servers'][$i]['port']

it should be empty default is 3306 and add 3309

Addinally you have to run the installer again

• executing the install file
• select "Reconfigure" over the mysql server
• In Authentication Method tab, select "Use Legacy Authentication

Method"

Answer 2

If you must have 2 MySQL instances running then use the features built into WAMPServer to amend the MySQL port number

RIGHT Click on the WAMPServer icon in the system tray and click the TOOLS menu item

See below, then click on "Use port other than 3306" and WAMPServer will update ALL the required files so that you can use a non standard port for MySQL
