How to change the mysql root password

I have installed MySQL server 5 on redhat linux. I can’t login as root so I can’t change the root password.

When I try to set one like this:

As if there is a root password set.

I have also tried resetting the password using (described here)

A little late to the game, but I had the same issue on a raspberry pi install and found out that it needs elevation. Adding a sudo to the front of the password change allowed it to work.

followed by an elevated sql access

If either are not run as sudo, it will fail.

The root user password is an empty string by default.

And (using password: NO) says that there is no password.

Do you try to login from another system? I imagine you can only login as root user locally.

I removed the MySQL installation and deleted the data files, and then reinstalled it.

Then I was able to set the root password. Once you set the root password to something. mysqladmin won’t let you reset it if you don’t know it.

To reset it, you’ve got to have ownership over how mysqld is executed, and feed it an init file to change the root password: https://dev.mysql.com/doc/refman/5.0/en/resetting-permissions.html

This helped me on Windows with MySQL Server 5.6. Make sure you change the mysqld path to point to where you have installed MySql Server, for me it was «C:\Program Files\mysql\MySQL Server 5.6\bin\mysqld.exe» :

Log on to your system as Administrator.

Stop the MySQL server if it is running. For a server that is running as a Windows service, go to the Services manager: From the Start menu, select Control Panel, then Administrative Tools, then Services. Find the MySQL service in the list and stop it.

If your server is not running as a service, you may need to use the Task Manager to force it to stop.

Create a text file containing the following statements. Replace the password with the password that you want to use.

Write the UPDATE and FLUSH statements each on a single line. The UPDATE statement resets the password for all root accounts, and the FLUSH statement tells the server to reload the grant tables into memory so that it notices the password change.

Open a console window to get to the command prompt: From the Start menu, select Run, then enter cmd as the command to be run.

If you installed MySQL to a location other than C:\mysql, adjust the command accordingly.

Chances are, you have MySQL running somewhere in your data center. If that’s the case, there might be a time when you need to set or change the root user password. This can happen when you’ve forgotten the password or when you’re looking to up your security game (remembering you set the original MySQL password to something far too simple).

As you might expect, the process is handled entirely through the command line and works with with either MySQL or MariaDB installations. The Linux distribution being used doesn’t matter (as long as you have admin access, either by way of su or sudo).

A word of warning: Given the current state of attacks, across the landscape of IT, I highly recommend you using seriously strong passwords for your databases. Use a random password generator and then store that in a password manager (instead of using an easily memorized password). Be safer than safe.

With that said, let’s get to work.

Setting the password for the first time

Do note, throughout this article, I will refer to MySQL, with the idea that everything will work for both MySQL and MariaDB.

Typically, during the installation of MySQL and MariaDB, you are asked to set an initial password. If, for whatever reason that didn’t happen, you will need to set a password for the first time. To do that, open up a terminal window and issue the following command:

An alternative method for setting the root password for the first time, one that also adds a bit of security to your MySQL database, is to use the mysql_secure_connection command. Not only will this command set the root user password, but it will allow you to remove anonymous users, disallow remote root login, and remove the test database. To use this command, simply type:

Answer the presented questions and your password will be set (as well as your database being a bit more secure).

SEE: Password management policy (Tech Pro Research)

Changing the MySQL root user password

To reset the password for MySQL you first must create a new file with the following contents:

ALTER USER ‘root’@’localhost’ IDENTIFIED BY ‘PASSWORD’;

Where PASSWORD is the new password to be used. Save that file as

Next, stop the MySQL daemon with the command:

sudo systemctl stop mysql

With the daemon stopped, issue the command:

Once your command prompt is returned, restart the MySQL daemon with the command:

sudo systemctl start mysql

You should now be able to log into the MySQL command prompt with the new admin password like so:

When prompted, type the admin password and you’re good to go.

Recover your MySQL password

What if you’ve forgotten your MySQL root user password? This could be quite the predicament … had the developers not thought of that eventuality. In order to recover the password, you simply have to follow these steps:

At this point, you need to issue the following MySQL commands to reset the root password:

mysql> use mysql;
​mysql> update user set authentication_string=password(‘NEWPASSWORD’) where user=’root’;
​mysql> flush privileges;
​mysql> quit

Where NEWPASSWORD is the new password to be used.

Restart the MySQL daemon with the command sudo service mysql restart. You should now be able to log into MySQL with the new password.

And that’s it. You can now set, reset, and recover your MySQL password.

A second warning

Just to be certain, I wanted to remind you how important it is to set a very difficult password for the MySQL root user. Those databases hold sensitive information, so the last thing you need is to make use of a weak password that can be easily cracked. Use a long password that you cannot memorize and store it in a password vault. You’ll be glad you did.

Mysql how to change root password

The SET PASSWORD statement assigns a password to a MySQL user account. The password may be either explicitly specified in the statement or randomly generated by MySQL. The statement may also include a password-verification clause that specifies the account current password to be replaced, and a clause that manages whether an account has a secondary password. ‘ auth_string ‘ and ‘ current_auth_string ‘ each represent a cleartext (unencrypted) password.

Rather than using SET PASSWORD to assign passwords, ALTER USER is the preferred statement for account alterations, including assigning passwords. For example:

Clauses for random password generation, password verification, and secondary passwords apply only to accounts that use an authentication plugin that stores credentials internally to MySQL. For accounts that use a plugin that performs authentication against a credentials system that is external to MySQL, password management must be handled externally against that system as well. For more information about internal credentials storage, see Section 6.2.15, “Password Management”.

The REPLACE ‘ current_auth_string ‘ clause performs password verification and is available as of MySQL 8.0.13. If given:

REPLACE specifies the account current password to be replaced, as a cleartext (unencrypted) string.

The clause must be given if password changes for the account are required to specify the current password, as verification that the user attempting to make the change actually knows the current password.

The clause is optional if password changes for the account may but need not specify the current password.

The statement fails if the clause is given but does not match the current password, even if the clause is optional.

REPLACE can be specified only when changing the account password for the current user.

For more information about password verification by specifying the current password, see Section 6.2.15, “Password Management”.

The RETAIN CURRENT PASSWORD clause implements dual-password capability and is available as of MySQL 8.0.14. If given:

RETAIN CURRENT PASSWORD retains an account current password as its secondary password, replacing any existing secondary password. The new password becomes the primary password, but clients can use the account to connect to the server using either the primary or secondary password. (Exception: If the new password specified by the SET PASSWORD statement is empty, the secondary password becomes empty as well, even if RETAIN CURRENT PASSWORD is given.)

If you specify RETAIN CURRENT PASSWORD for an account that has an empty primary password, the statement fails.

For more information about use of dual passwords, see Section 6.2.15, “Password Management”.

SET PASSWORD permits these auth_option syntaxes:

Assigns the account the given literal password.

Assigns the account a password randomly generated by MySQL. The statement also returns the cleartext password in a result set to make it available to the user or application executing the statement.

For details about the result set and characteristics of randomly generated passwords, see Random Password Generation.

Random password generation is available as of MySQL 8.0.18.

Under some circumstances, SET PASSWORD may be recorded in server logs or on the client side in a history file such as

SET PASSWORD can be used with or without a FOR clause that explicitly names a user account:

With a FOR user clause, the statement sets the password for the named account, which must exist:

With no FOR user clause, the statement sets the password for the current user:

Any client who connects to the server using a nonanonymous account can change the password for that account. (In particular, you can change your own password.) To see which account the server authenticated you as, invoke the CURRENT_USER() function:

If a FOR user clause is given, the account name uses the format described in Section 6.2.4, “Specifying Account Names”. For example:

SET PASSWORD interprets the string as a cleartext string, passes it to the authentication plugin associated with the account, and stores the result returned by the plugin in the account row in the mysql.user system table. (The plugin is given the opportunity to hash the value into the encryption format it expects. The plugin may use the value as specified, in which case no hashing occurs.)

Setting the password for a named account (with a FOR clause) requires the UPDATE privilege for the mysql system schema. Setting the password for yourself (for a nonanonymous account with no FOR clause) requires no special privileges.

Statements that modify secondary passwords require these privileges:

The APPLICATION_PASSWORD_ADMIN privilege is required to use the RETAIN CURRENT PASSWORD clause for SET PASSWORD statements that apply to your own account. The privilege is required to manipulate your own secondary password because most users require only one password.

When the read_only system variable is enabled, SET PASSWORD requires the CONNECTION_ADMIN privilege (or the deprecated SUPER privilege), in addition to any other required privileges.

For additional information about setting passwords and authentication plugins, see Section 6.2.14, “Assigning Account Passwords”, and Section 6.2.17, “Pluggable Authentication”.

This function was removed in MySQL 8.0.11

1.if you in skip-grant-tables mode
in mysqld_safe:

and then, in terminal:

2.not in skip-grant-tables mode
just in mysql:

Jus login to mysql with sudo

Step 1: Create a new file in your root directory( e.g C:) Step 2: Write this ALTER USER ‘root’@’localhost’ IDENTIFIED BY ‘abc’ and save it Step 3: If your Mysql service is already running, please stop this and open your CMD Step 4: Go to your Mysql installation directory (e.g C:\Program Files\MySQL\MySQL Server 8.0\bin) and type this command

Step 5: Execute this command and you are good to go 🙂

I am using 8.0.23 but had multiple issues. Here are the issues and solutions. I followed the mysql docs and was able to do the reset, though I had isues. I have provided my solutions and a sample reset script.

In the script, I will reset root to New%Password
