Fix :: Unable to login at phpMyadmin after revoking MySQL root user

Problem Statement


I am not able to login into phpMyadmin after revoking root user.


Solution


This issue was fixed by re-creating the root user through MySQL command prompt with following steps:


  1. Start the MySQL with skip-grant-tables option

    mysqld_safe --skip-grant-tables;
  2. Login to MySQL command line and run the following command.

    insert into `user` (`Host`, `User`, `Password`, `Select_priv`, `Insert_priv`, `Update_priv`, `Delete_priv`, `Create_priv`, `Drop_priv`, `Reload_priv`, `Shutdown_priv`, `Process_priv`, `File_priv`, `Grant_priv`, `References_priv`, `Index_priv`, `Alter_priv`, `Show_db_priv`, `Super_priv`, `Create_tmp_table_priv`, `Lock_tables_priv`, `Execute_priv`, `Repl_slave_priv`, `Repl_client_priv`, `Create_view_priv`, `Show_view_priv`, `Create_routine_priv`, `Alter_routine_priv`, `Create_user_priv`, `ssl_type`, `ssl_cipher`, `x509_issuer`, `x509_subject`, `max_questions`, `max_updates`, `max_connections`, `max_user_connections`) 
    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','','','','','0',' 0','0','0'); 
  3. Following command will reset the root password with password you write in new-password field.

    Update user set Password=PASSWORD('new-password') where user='root';
    flush privileges;
