Cause: MySQL username and password do not correspond to the username and password of the phpMyAdmin configuration file, so I can't even go up.
Solve:
1. Login MySQL Change password
You can log in with the CMD console or you can log in with the MySQL console of Wamp.
->use MySQL
->update User Set Password=password ("password") where user= ' root ';
2. Modify the user name password for the phpMyAdmin configuration file
config.inc.php files under \wamp\apps\phpmyadmin3.4.10.1
$cfg [' Servers '] [$i] [' user '] = ' root ';
$cfg [' Servers '] [$i] [' password '] = ' password ';
3. This step is important, related to your half-day effort. That's why I'm doing this one step at a times.
After restarting the service, re-login phpMyAdmin
The unmodified page then appears #1045-access denied for user ' root ' @ ' localhost ' (using Password:yes)
Then the last step is to refresh the page (note: Instead of reopening phpmyadmin, instead of refreshing the wrong page, it's generally OK)
Wampserver login MySQL appears #1045-access denied for user ' root ' @ ' localhost ' (using password:yes) issue
