Setting, Changing And Resetting MySQL Root Passwords

This tutorial explains how you can set, change and reset (if you’ve forgotten the password) MySQL or MariaDB root passwords. Time and again I see problems like mysqladmin:  connect to server at ‘localhost’ failed error: ‘Access denied for user ‘root’@’localhost’ (using password: YES)’. So I thought it’s time to remind you how to solve MySQL related password problems. If you are just looking for a quick fix how to reset a MySQL root password you can find that at the bottom of this tutorial.

mysqladmin Command To Change Root Password

Method 1 – Set up root password for the first time

If you have never set a root password for MySQL, the server does not require a password at all for connecting as root. To set up a root password for the first time, use the mysqladmin command at the shell prompt as follows:

mysqladmin -u root password newpass

If you want to change (or update) a root password, then you need to use the following command:

mysqladmin -u root -p oldpassword newpass

Enter password:

If you get…

mysqladmin: connect to server at ‘localhost’ failed
error: ‘Access denied for user ‘root’@’localhost’ (using password: YES)’

then follow the instructions below on how to recover your MySQL password.

An alternative to using the mysqladmin command when setting the MySQL or MariaDB root password the first time is to use the mysql_secure_conection command. This command will not only ask for the old- and new MySQL root password but will also do some other security settings like disabling the test database.

Here is how to use that command:


Answer the questions as shown below:

Change the root password? [Y/n] <– y
New password: <– Enter a new MySQL root password
Re-enter new password: <– Repeat the MySQL root password
Remove anonymous users? [Y/n] <– y
Disallow root login remotely? [Y/n] <– y
Remove test database and access to it? [Y/n] <– y
Reload privilege tables now? [Y/n] <– y

The above answers are recommendations, you are free to choose other settings e.g. when you prefer to keep the test databases or need remote access for the root user. Note: you do not need remote access to use PHPMyAdmin remotely.

Change MySQL password for other users

To change a normal user password you need to type:

mysqladmin -u user-name -p oldpassword newpass


Method 2 – Update or change password

MySQL stores usernames and passwords in the user table inside the MySQL database. You can directly update a password using the following method to update or change passwords:

1) Login to the MySQL server, type the following command at the shell prompt:

mysql -u root -p

2) Use the mysql database (type commands at the mysql> prompt):

mysql> use mysql;

3) Change password for a user:

mysql> update user set password=PASSWORD(“newpass”) where User=’ENTER-USER-NAME-HERE’;

4) Reload privileges:

mysql> flush privileges;
mysql> quit

This method you need to use while using PHP or Perl scripting.


Recover MySQL root password

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

Step # 1: Stop the MySQL server process.

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

Step # 3: Connect to the MySQL server as the root user.

Step # 4: Set a new root password.

Step # 5: Exit and restart the MySQL server.

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

Step # 1: Stop the MySQL service:

service mysql stop


Stopping MySQL database server: mysqld.

Step # 2: 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

Step # 3: Connect to the MySQL server using the MySQL client:

mysql -u root

Step # 4: Set a new MySQL root user password:

mysql> use mysql;
mysql> update user set password=PASSWORD(“NEW-ROOT-PASSWORD”) where User=’root’;
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_safe[6186]: ended

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

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
