I was following some tutorials on the internet to change the password of my mysql user in phpMyAdmin and in the end I ended up deleting this user. I did not have access to phpMyAdmin and I do not know how to solve this problem, I'm using Wamp Server.
The following message appears:
# 1130 - Host 'localhost' is not allowed to connect to this MySQL server
Is there any way to restart or return to the source settings?
Try what's in the answer to this other question from a user in a situation identical to the one you mentioned. HERE!
The solution presented is to run a .bat file in the xampp folder or if it does not exist, run the following code:
@echo off
echo USE mysql; >resetroot.sql
echo. >>resetroot.sql
echo REPLACE INTO user VALUES ('localhost', 'root', '', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', '', '', '', '', 0, 0, 0, 0, '', ''); >>resetroot.sql
echo REPLACE INTO user VALUES ('127.0.0.1', 'root', '', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', '', '', '', '', 0, 0, 0, 0, '', ''); >>resetroot.sql
echo REPLACE INTO user VALUES ('localhost', 'pma', '', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', '', '', '', '', 0, 0, 0, 0, '', ''); >>resetroot.sql
bin\mysqld.exe --no-defaults --bind-address=127.0.0.1 --bootstrap --console --standalone <resetroot.sql >nul
del resetroot.sql
echo.
echo Passwoerter fuer Benutzer "root" und "pma" wurden geloescht.
echo Passwords for user "root" and "pma" were deleted.
echo.
pause
And in mysql do the following:
REPLACE INTO user VALUES ('localhost', 'root', '', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', '', '', '', '', 0, 0, 0, 0, '', '');
REPLACE INTO user VALUES ('127.0.0.1', 'root', '', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y', '', '', '', '', 0, 0, 0, 0, '', '');
REPLACE INTO user VALUES ('localhost', 'pma', '', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', '', '', '', '', 0, 0, 0, 0, '', '');
