mySQL root password config

1. Confirm MySQL version
Firstly, you must confirm which version of MySQL on Ubuntu you are running as commands will be different.

mysql -V

If on MySQL version 8, you will see something like:

mysql Ver 8.0.20-0ubuntu0.20.04.1 for Linux on x86_64 ((Ubuntu))

If you are on MySQL version 5, you will see something similar to:

mysql  Ver 14.14 Distrib 5.7.36, for Linux (x86_64) using  EditLine wrapper

2. Restart MySQL with skip-grant-table
In order to skip the grant tables and reset the root password, we must first stop the MySQL service. Enter your Linux password if prompted.

sudo /etc/init.d/mysql stop

Ensure the directory /var/run/mysqld exists and correct owner set.

sudo mkdir /var/run/mysqld

sudo chown mysql /var/run/mysqld

Now start MySQL with the --skip-grant-tables option. The & is required here.

sudo mysqld_safe --skip-grant-tables&

You should see something similar:

[1] 1283
user@server:~$ 2019-02-12T11:15:59.872516Z mysqld_safe Logging to syslog.
2019-02-12T11:15:59.879527Z mysqld_safe Logging to '/var/log/mysql/error.log'.
2019-02-12T11:15:59.922502Z mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql

Now press ENTER to return to the Linux BASH prompt.

3. Change MySQL Root Password
You can now log in to the MySQL root account without a password.

sudo mysql --user=root mysql
 Save

Once logged in, you will see the mysql> prompt.

MySQL 8 – Reset Root Password
For MySQL 8 on Ubuntu, run following commands.

UPDATE mysql.user SET authentication_string=null WHERE User='root';

flush privileges;

Replace your_password_here with your own. (Generate a strong password here)
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your_password_here';

Flush privileges again.

flush privileges;

Exit MySQL.

exit


4. Test New Root Password
Make sure all MySQL processes are stopped before starting the service again.

sudo killall -u mysql

If you see a message similar to below, press ENTER to continue.

2020-05-30T07:23:38.547616Z mysqld_safe mysqld from pid file /var/lib/mysql/ubuntu.pid ended

Start MySQL again.

sudo /etc/init.d/mysql start

Log in to MySQL again and you should now be prompted for a password.

sudo mysql -p -u root

Enter your MySQL root password. If correct, you should see something like:

Welcome to the MySQL monitor.  Commands end with ; or g.
Your MySQL connection id is 8
