Introduction

This tutorial will cover how to reset the root password for older and newer versions of MySQL and MariaDB.

Please do not make any edits to this article. Its contents are currently under review and being merged with the Ubuntu Server Guide. To find the Ubuntu Server Guide related to your specific version, please go to:

Step 5 — Restart the Database Server Normally

For MySQL, use:

For MariaDB, use:

Then, restart the service using systemctl.

systemctl start mysql

systemctl start mariadb

Now you can confirm that the new password has been applied correctly by running:

mysql root

The command should now prompt for the newly assigned password. Enter it, and you should gain access to the database prompt as expected.

Now, run the command with correct root password which is set in previous step. If you provide the correct password then it will be able to connect successfully with the server.

Changing Password using UPDATE

Изменение пароля root mysql ubuntu

Again, exit from the server and restart the database server before testing the new password.

$ sudo service mysql restart

Изменение пароля root mysql ubuntu

Start the database without loading the grant tables or enabling networking:

mysqld_safe —skip-grant-tables —skip-networking

The ampersand at the end of this command will make this process run in the background so you can continue to use your terminal.

You’ll immediately see a database shell prompt instead.

Now that you have root access, you can change the root password.

На какие бы мы ни встали ходули, без своих ног не обойдемся (П. Буаст).

ароли сложно запомнить, поэтому, если вы забыли пароль root MySQL, к счастью, есть способ его изменить. Этот пост был написан для вас, и к концу этого поста вы успешно измените пароль MySQL.

Прежде чем перейти непосредственно к решению, предполагается, что вы используете последнюю версию базы данных MySQL в системе Ubuntu 20.04 LTS. В этом посте будет предоставлено пошаговое руководство по изменению пароля root MySQL в Ubuntu 20.04. Итак, не теряя времени, приступим.

Изменение пароля root mysql ubuntu

тот учебник покажет вам, как сбросить в MySQL пароль для root на вашем Linux VPS в случае, если Вы забыли его.

1.Войдите как root через SSH и остановитt сервер MySQL.

debian-ubuntu# /etc/init.d/mysql stop
centos-fedora# /etc/init.d/mysqld stop

2. Запустите сервер MySQL с опцией «skip-grant-tables».

# mysqld_safe —skip-grant-tables &

Это отключит проверку подлинности MySQL и запустить процесс в фоновом режиме.

3. Войдите в MySQL как root.

# mysql -u root mysql

4. Сбросьте пароль MySQL.

Заменить «new_your_password»  новым паролем!

5. После того, как пароль будет сброшен, запустите сервер MySQL в нормальном режиме.

debian-ubuntu# /etc/init.d/mysql restart
centos-fedora# /etc/init.d/mysqld restart

Теперь вы можете подключиться к MySQL как пользователь root, используя новый пароль.

Введите «mysql -u root -p» в терминале, и введите пароль при появлении соответствующего запроса.

Step 2 — Restarting the Database Server Without Permission Checks

Depending on which database server you’ve installed, the way of starting the server without loading the grant tables differs.

Configuring MariaDB to Start Without Grant Tables

In order to start the MariaDB server without the grant tables, we’ll use the systemd unit file to set additional parameters for the MariaDB server daemon.

Then start the MariaDB server:

This command won’t produce any output, but it will restart the database server, taking into account the new environment variable settings.

You can ensure it started with sudo systemctl status mariadb.

You’ll immediately see a database shell prompt:

Now that you have access to the database server, you can change the root password as shown in Step 3.

Configuring MySQL to Start Without Grant Tables

In order to start the MySQL server without its grant tables, you’ll alter the systemd configuration for MySQL to pass additional command-line parameters to the server upon startup.

systemctl edit mysql

This command will open a new file in the nano editor, which you’ll use to edit MySQL’s service overrides. These change the default service parameters for MySQL.

MySQL service overrides

/usr/sbin/mysqld —skip-grant-tables —skip-networking

The first ExecStart statement clears the default value, while the second one provides systemd with the new startup command, including parameters to disable loading the grant tables and networking capabilities.

Press CTRL-x to exit the file, then Y to save the changes that you made, then ENTER to confirm the file name.

Reload the systemd configuration to apply these changes:

Now start the MySQL server:

The command will show no output, but the database server will start. The grant tables and networking will not be enabled.

Now that you have access to the server, you can change the root password.

/usr/sbin/mysqld —daemonize —pid-file=/run/mysqld/mysqld.pid —skip-grant-tables —skip-networking

Not everybody is good at remembering passwords. Do not panic in case you cannot remember the password of your MySQL account. You can still access the MySQL server and change the root password even if you have misplaced or forgotten the root password. But how is a beginner going to perform this operation?

This blog will demonstrate the method for changing the MySQL root password in Ubuntu 22.04. Let’s get started.

Note: The given method for changing password only implies for MySQL version greater or equal to “8”.

Check MySQL version

First thing you need to do is check the version of installed MySQL on your system:

As you can see, we have installed MySQL version “8.0.29”:

Skipping Networking and Grant Tables

MYSQL server should start without networking checks and granting tables. To do so, set the value of “MYSQLD_OPTS”:

systemctl set-environment =

Изменение пароля root mysql ubuntu

Then head towards the next step.

Start MySQL service

systemctl start mysql.service

MySQL service is now started:

Изменение пароля root mysql ubuntu

Again, check the status of the MySQL service to ensure that it is currently active and running on the Ubuntu 22.04 system:

Passwords are hard to remember, so if you have forgotten the MySQL root password, luckily, there is a way to change it. This post has been written for you, and by the end of this post, you will have successfully changed the password of MySQL.

Before getting straight to the solution, it is assumed that you are using the latest version of the MySQL database on Ubuntu 20.04 LTS system. This post will provide a step-by-step guide on how to change the MySQL root password in Ubuntu 20.04. So, without wasting any time, let’s start.

Check the version of MySQL on Ubuntu 20

First of all, check the version of your MySQL because this post contains the solution of changing the root password on version 8 or higher. If the version of your MySQL is lower than 8, then the solution will be different. The command for checking the version of MySQL is given below:

Изменение пароля root mysql ubuntu

Stop the MySQL server

To change the MySQL root password, you first need to shut down the MySQL server, and you can do so using the command:

$ sudo systemctl stop mysql.service

Изменение пароля root mysql ubuntu

$ sudo systemctl status mysql.service

Изменение пароля root mysql ubuntu

Skip Grant Tables & Networking

To start the MySQL server without granting the tables and networking check, set the environment variable “MYSQLD_OPTS” which MySQL uses on startup:

$ sudo systemctl set-environment MYSQLD_OPTS=»—skip-networking —skip-grant-tables»

Изменение пароля root mysql ubuntu

Alright, the environment variable is set, and we can log in to the MySQL shell without providing any password.

Start the MySQL service

After setting the environment variable “MYSQLD_OPTS”, start the MySQL service now using the command:

$ sudo systemctl start mysql.service

Изменение пароля root mysql ubuntu

Confirm the status of the MySQL Server

Confirm the status of the MySQL service, whether it is running or not:

Изменение пароля root mysql ubuntu

Sign In to the MySQL shell

Изменение пароля root mysql ubuntu

Without providing any password, you will log in to the MySQL shell.

Alter the root password

Now, flush the privileges first:

Изменение пароля root mysql ubuntu

Изменение пароля root mysql ubuntu

Изменение пароля root mysql ubuntu

Revert Database Server to Normal settings

For restarting the database server in “normal” mode, it is required to “revert” the changes we have made so that the networking is enabled and grant tables are loaded.

To do so, firstly unset the “MYSQLD_OPTS” environment variable which you have set previously:

$ sudo systemctl unset-environment MYSQLD_OPTS

Изменение пароля root mysql ubuntu

$ sudo systemctl revert mysql

Изменение пароля root mysql ubuntu

Kill all MySQL processes & Restart the MySQL service

Now, kill all the processes of MySQL before restarting the MySQL server:

Изменение пароля root mysql ubuntu

$ sudo systemctl restart mysql.service

Изменение пароля root mysql ubuntu

Log in with the newly set Password

Log in to the MySQL shell with the newly set password:

Изменение пароля root mysql ubuntu

Изменение пароля root mysql ubuntu

This is it. MySQL’s root password is successfully changed, and you are logged back into the MySQL shell.

Wrap Up

In this step-by-step guide, you have learned to change the MySQL root password on the Ubuntu 20.04 LTS system. This post contains a profound and easy-to-understand solution on resetting the root password of MySQL on Ubuntu 20.04.

Step 1 — Identifying the Database Version

Most modern Linux distributions ship with either MySQL or MariaDB, a popular drop-in replacement which is fully compatible with MySQL. Depending on the database used and its version, you’ll need to use different commands to recover the root password.

You’ll see some output like this with MySQL:

mysql Ver 14.14 Distrib 5.7.16, for Linux (x86_64) using EditLine wrapper

Or output like this for MariaDB:

mysql Ver 15.1 Distrib 5.5.52-MariaDB, for Linux (x86_64) using readline 5.1

Make note of which database and which version you’re running, as you’ll use them later. Next, you need to stop the database so you can access it manually.

Step 4 — Reverting Your Database Server to Normal Settings

In order to restart the database server in its normal mode, you have to revert the changes you made so that networking is enabled and the grant tables are loaded. Again, the method you use depends on whether you used MariaDB or MySQL.

For MariaDB, unset the MYSQLD_OPTS environment variable you set previously:

Then, restart the service using systemctl:

systemctl restart mariadb

For MySQL, remove the modified systemd configuration:

Removed /etc/systemd/system/mysql.service.d/override.conf.
Removed /etc/systemd/system/mysql.service.d.

Then, reload the systemd configuration to apply the changes:

Finally, restart the service:

You’ll be prompted for a password. Enter your new password, and you’ll gain access to the database prompt as expected.

To resolve this problem ,a fast and always working way is the «Password Resetting» .

Step 3 — Changing the Root Password

The database server is now running in a limited mode; the grant tables are not loaded, and there’s no networking support enabled. This lets you access the server without providing a password, but it prohibits you from executing commands that alter data. To reset the root password, you must load the grant tables now that you’ve gained access to the server.

Дополнительно:  YOU CAN'T COPY THE FILE UPDATE.ZIP IN THE R-Flyme Official Forum

Tell the database server to reload the grant tables by issuing the FLUSH PRIVILEGES command:

You can now change the root password. The method you use depends on whether you are using MariaDB or MySQL.

Changing the MariaDB Password

You’ll see this output indicating that the password changed:

Query OK, 1 row affected (0.00 sec)

Query OK, 0 rows affected (0.01 sec)

The password is now changed. Type exit to exit the MariaDB console and proceed to Step 4 to restart the database server in normal mode.

Changing the MySQL Password

You’ll see this output indicating the password was changed successfully:

You’ll see output similar to the previous command:

The password is now changed. Exit the MySQL console by typing exit.

Let’s restart the database in normal operational mode.

Step 4 — Changing the Root Password

Let’s tell the database server to reload the grant tables by issuing the FLUSH PRIVILEGES command.

Now we can actually change the root password.

For MySQL 5.7.5 and older as well as MariaDB 10.1.20 and older, use:

Make sure to replace new_password with your new password of choice.

Remember to reload the grant tables after this.

In either case, you should see confirmation that the command has been successfully executed.

The password has been changed, so you can now stop the manual instance of the database server and restart it as it was before.

Шаг 1. Проверьте версию MySQL в Ubuntu 20

Прежде всего, проверьте версию своего MySQL, потому что этот пост содержит решение по изменению пароля root в версии 8 или выше. Если версия вашего MySQL ниже 8, решение будет другим. Команда для проверки версии MySQL приведена ниже.

Шаг 2. Остановите сервер MySQL

Чтобы изменить пароль root MySQL, вам сначала нужно выключить сервер MySQL, и вы можете сделать это с помощью команды:

$ sudo systemctl stop mysql.service

Проверьте состояние сервера MySQL, чтобы проверить его, используя команду:

$ sudo systemctl status mysql.service

Step 1 — Identifying the Database Version and Stopping the Server

If you’re running MariaDB, you’ll see “MariaDB” preceded by the version number in the output:

mysql Ver 15.1 Distrib 10.3.25-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

You’ll see output like this if you’re running MySQL:

mysql Ver 8.0.22-0ubuntu0.20.04.3 for Linux on x86_64 ((Ubuntu))

systemctl stop mariadb

For MySQL, shut down the database server by running:

With the database stopped, you can restart it in safe mode to reset the root password.

mysql Ver 15.1 Distrib 10.1.47-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

mysql Ver 14.14 Distrib 5.7.32, for Linux (x86_64) using EditLine wrapper

Prerequisites

To recover your root MySQL/MariaDB password, you will need:

Шаг 7. Измените пароль root

Теперь сначала удалите привилегии.

Выберите базу данных MySQL.

И установите новый пароль для пользователя root с помощью команды Alter, набрав следующую инструкцию.

Вместо «the-new-password» укажите свой новый пароль. После успешного изменения пароля root MySQL выйдите из оболочки MySQL.

How can I reset my MySQL password?

For either method, once have received a message indicating a successful query (one or more rows affected), flush privileges:

Then stop the mysqld process and relaunch it with the classical way:

sudo /etc/init.d/mysql stop
sudo /etc/init.d/mysql start

All packages can be found browsing synaptic.

Войдите в систему с новым паролем

Теперь войдите в оболочку MySQL с новым установленным паролем.

Введите недавно установленный пароль в команде ALTER.

Все. Пароль root MySQL успешно изменен, и вы снова вошли в оболочку MySQL.

Шаг 4. Запустите службу MySQL

После установки переменной окружения MYSQLD_OPTS запустите службу MySQL, используя команду:

$ sudo systemctl start mysql.service

To recover your MySQL or MariaDB root password, you will need:

Query OK, 0 rows affected (0.001 sec)

Шаг 3. Пропустите таблицы грантов и нетворкинг

Чтобы запустить сервер MySQL без предоставления таблиц и проверки сети, установите переменную среды MYSQLD_OPTS, которую MySQL использует при запуске.

$ sudo systemctl set-environment MYSQLD_OPTS=»—skip-networking —skip-grant-tables»

Подтвердите статус сервера MySQL

Подтвердите статус службы MySQL, работает она или нет:

Шаг 6. Войдите в оболочку MySQL

Без ввода пароля вы войдете в оболочку MySQL.

Another way, purge

I also had some problems with mysql just not accepting my password. I tried the other way as well and it just ended up being difficult. I had not been able to use mysql so it was empty anyway. If this is also your case you may opt for the PURGE way. This removes every file related to mysql. Depending on your installation the packages might be diffrent, mysql-server in 6.10 is called mysql-server-5.0 as an example.

USE THIS AS A LAST RESORT METHOD, YOU WILL LOSE ALL YOUR MYSQL DATA

sudo apt-get —purge remove mysql-server mysql-common mysql-client

sudo apt-get install mysql-server mysql-common mysql-client

In the next step be sure to chance the your-new-password with the password you want!

You should now be logged in as root. Make sure to notedown your password! Thanks to Illuvator for posting this method in the ubuntu forum.

Шаг 8. Завершите все процессы MySQL и перезапустите службу MySQL

Прежде всего, убейте все процессы MySQL еще до перезапуска сервера MySQL.

Получив результат, нажмите «Enter» и перезапустите сервер MySQL, используя команду, приведенную ниже.

$ sudo systemctl restart mysql.service

Step 2 — Stopping the Database Server

To change the root password, you have to shut down the database server beforehand.

You can do that for MySQL with:

And for MariaDB wtih:

After the database server is stopped, you’ll access it manually to reset the root password.
