The main purpose of this article is to tell you briefly about how to forget the root password of mysql. You can check the relevant professional terms on the Internet or find some related books to supplement them. We will not dabble here, so let's go straight to the topic. I hope that the root password of mysql forgot how to do it. This article can bring you some practical help.

1. First, close mysql and use the `--skip-grant-tables' parameter to start mysqld.

[root@iZwz9ga6kootlfn5ejt8axZ ~] # service mysqld stop [root@iZwz9ga6kootlfn5ejt8axZ ~] # / usr/bin/safe_mysqld-skip-grant-tables&

Or

In the MySQL configuration file my.cnf, add skip-grant-tables under [mysqld], shut down the MySQL service and restart it.

Can log in without a password

2. You can log in to mysql without a password and change the password.

[root@iZwz9ga6kootlfn5ejt8axZ ~] # mysql-urootmysql > update mysql.user set password=password ("new_pass") where user= "root"; mysql > flush privileges

The password was changed successfully.

I want to close mysql at this time.

[root@iZwz9ga6kootlfn5ejt8axZ ~] # service mysqld stopStopping mysqld: [OK]

The command was executed successfully, but

[root@iZwz9ga6kootlfn5ejt8axZ ~] # netstat-tnlp | grep mysqltcp 0 0 0.0.0.0 tnlp 3306 0.0.0.0 LISTEN 13916/mysqld

Find that the mysql port still exists. Check the process.

[root@iZwz9ga6kootlfn5ejt8axZ ~] # ps-ef | grepmysql | grep-v grepmysql 13916 12911 0 11:42 pts/3 00:00:00 mysqld-- skip-grant-tables

Finally, mysqladmin shutdown is used to close successfully.

[root@iZwz9ga6kootlfn5ejt8axZ] # mysqladmin-uroot-ppassword shutdown
