MySQL Resetting root password



If you have forgotten your root password, you will need to start mysql service with --skip-grant-tables mode and then run the following 2 commands to reset it to root / root@123

UPDATE mysql.user SET Password = password('root@123') WHERE Host = 'localhost' AND User = 'root';

REPLACE INTO mysql.user VALUES ('%','root','*A00C34073A26B40AB4307650BFB9309D6BFA6999', '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,'','');

You may now remove the skip grant tables option and restart mysql service. I assume you are not using old-passwords option in my.cnf that makes it compatible with mysql version 3.0!

MySQL Architecture -Client Server Architecture

Client/Server Overview The MySQL database system operates using a client/server architecture. The server is a central program that manages database contents, and client programs connect to the server to retrieve or modify the data. MySQL also includes non-client utility programs and scripts. MySQL Server:   This is the mysqld program that manages database and tables. Most users choose binary MySQL distribution that includes a server ready to run with the capabilities they need, but it's also possible to compile MySQL from source. Client Programs:  These are programs that communicate with the server by sending requests to it over a network connection. The server acts on each request and returns a response to the client. For example you can use the mysql client to send queries to the server, and the server returns the query results. A client program can connect locally to a server running on the same machine or remotely to a server running on a different mac...
