1: Use Set password command
First log in to MySQL.
Format:mysql> set password for user name @localhost = password (' new password ');
2: With Mysqladmin
Format: Mysqladmin-u username-P Old password password new password
3: Edit user table directly with update
First log in to MySQL.
mysql> use MySQL;
mysql> Update user set Password=password (' 123 ') where user= ' root ' and host= ' localhost ';
mysql> flush Privileges;
4: When you forget the root password, you can do this
Take windows as an example:
1. Close the running MySQL service.
2. Open the DOS window and go to the Mysql\bin directory.
3. Enter Mysqld--skip-grant-tables carriage return. --skip-grant-tables means skipping permission table authentication when starting the MySQL service.
4. Open a DOS window again (because the DOS window is no longer moving), go to the Mysql\bin directory.
5. Enter MySQL return and, if successful, the MySQL prompt > will appear.
6. Connection rights database: use MySQL;.
6. Change Password: Update user set Password=password ("123") where user= "root"; (don't forget the last semicolon).
7. Refresh permissions (required steps): flush privileges;.
8. Quit quit.
9. Log out of the system and then enter, using the username root and the new password you just set 123 to log in.
The above describes the MySQL user to modify the password, including the aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
