Problem 1:
2002 Unable to log in to the MySQL server
phpMyAdmin cannot log in. After entering the user name and password and clicking "Execute", it keeps reporting "#2002 Unable to log in to the MySQL server".
Solution, change
$cfg['Servers'][$i]['host'] = 'localhost';
in the config.default.php file under the "phpMyAdmin/libraries" folder to
$cfg['Servers'][$i]['host'] = '127.0.0.1';
Question 2:
#1045 Unable to log in to the MySQL service
1. Modify the /phpmyadmin/libraries/config.default.PHP file.
Find the following two lines
$cfg['Servers'][$i]['nopassword'] = false; $cfg['Servers'][$i]['AllowNoPassword'] = false;
Modify to:
$cfg['Servers'][$i]['nopassword'] = true; $cfg['Servers'][$i]['AllowNoPassword'] = true;
2. If you still cannot log in at this time, try clearing cookies. Or just enter a few characters.
3. Change the password promptly after successful login.
