MySQL is a relational database management system, and MySQL is one of the best RDBMS (relational database Management system, relational data management systems) application software in WEB applications. With PHP and Apache to form a good development environment. Therefore, it is widely used. Many people will encounter MySQL needs to change the password, such as the password is too simple, forget the password and so on. Here I will teach you several ways to modify the MySQL password. Here, for example, change the root password, the operating system is windows.

Note: Modifying MySQL requires root access in MySQL, so the general user cannot change the password unless the administrator is requested.

1. Using the Set password command

1. Open terminal win+r, input cmd enter can open;
2. By mysql-u user name-p to specify the root user to log in to MySQL, enter after entering will prompt to enter the password.
3. Modify the root user password for MySQL, format:mysql> set password for username @localhost = password (' new password '); Example:mysql> set password for [email protected] = password (' root '); The above example changes the user root password to root;
4. Login again, enter the new password root is OK;

2 with Mysqladmin

1. Open terminal Win+r input cmd enter to open;
2. Modify the root user password format for MySQL: mysqladmin-u username-P Old password Password new password example: mysqladmin-uroot-p123; password 123456

The above example will user root the original password 123; Change to a new password 123

Re-login, enter the new password 123 is OK;
