[SOLVED] MySQL set root password wrong


I was trying to remove the root password. Somehow.. by reading an old post here, I managed to change my password to something that I don’t know.I used this exact command:

mysqladmin -u root -p password ''

After entering this and my password, I couldn’t log in as root anymore. What is that “” representing ?

Recover MySQL root password

You can recover a MySQL database server password with the following five easy steps:

  1. Stop the MySQL server process.

  2. Start the MySQL (mysqld) server/daemon process with the –skip-grant-tables option so that it will not prompt for a password.

  3. Connect to the MySQL server as the root user.

  4. Set a new root password.

  5. Exit and restart the MySQL server.

Here are the commands you need to type for each step (log in as the root user):

  1. Stop the MySQL service:
service mysql stop


Stopping MySQL database server: mysqld.

  1. Start the MySQL server w/o password:
mysqld_safe --skip-grant-tables &


[1] 5988

Starting mysqld daemon with databases from /var/lib/mysql
mysqld_safe[6025]: started
  1. Connect to the MySQL server using the MySQL client:
mysql -u root

  1. Set a new MySQL root user password:

MySQL 5.7.5 and earlier

mysql> use mysql;
mysql> update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';
mysql> flush privileges;
mysql> quit

MySQL 5.7.6 and newer

mysql> use mysql;
mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD("newpass");
mysql> flush privileges;
mysql> quit

Step # 5: Stop the MySQL server:

service mysql stop


Stopping MySQL database server: mysqld
STOPPING server from pid file /var/run/mysqld/mysqld.pid
mysqld_safe[6186]: ended

[1]+  Done                    mysqld_safe --skip-grant-tables

Or use this command to stop MySQL if the command above fails to stop it (which command works depends on the MySQL version):

killall mysqld

The output might differ based on the Linux distribution. Don’t worry unless it reports an error. Start the MySQL server and test it:

service mysql start
mysql -u root -p
