$ sudo mysql_secure_installation

Press Enter. When prompted for password, provide the root password set above.

Answer the prompts as below:

Enter current password for root (enter for none): <Enter password>
VALIDATE PASSWORD PLUGIN can be used to test passwords 
and improve security. It checks the strength of password 
and allows the users to set only those passwords which are 
secure enough. Would you like to setup VALIDATE PASSWORD plugin? 

Press y|Y for Yes, any other key for No: Y 

There are three levels of password validation policy: 

LOW    Length >= 8 
MEDIUM Length >= 8, numeric, mixed case, and special characters 
STRONG Length >= 8, numeric, mixed case, special characters and dictionary                 

Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 1 
Using existing password for root.

Change the password for root ? ((Press y|Y for Yes, any other key for No) : d
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 
Thanks for using MariaDB!

Check MySQL version.

To confirm the installed version, first, connect to MySQL with the set root password.

$ mysql -u root -p 

Run the below command to display version

$ SELECT VERSION();
+-----------+ 
| VERSION() | 
+-----------+ 
| 5.7.31    | 
+-----------+ 
1 row in set (0.00 sec)

Step 4: Create MySQL User (Optional, testing only)

While still connected to MySQL, run the following commands to create a user:

CREATE USER 'user'@'%' IDENTIFIED BY 'MyStrongPass.';
GRANT ALL PRIVILEGES ON * . * TO 'user'@'%'; 
FLUSH PRIVILEGES;
exit

Step 5: Enable MySQL remote access (Optional)

By default, MySQL remote access is disabled. To enable it we need to edit mysqld.cnf file as below:

$ sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf

Look for the line ‘bind_address’ and change as below:

# By default we only accept connections from localhost 
#bind-address   = 127.0.0.1 
bind-address   = 0.0.0.0

Save the file and restart mysql

$ sudo systemctl restart mysql

Allow remote connections through the firewall

$ sudo ufw allow from <remote_IP_address> to any port 3306
$ sudo ufw enable

To access the database from a remote machine, run the following command:

$ mysql -u user -h database_server_ip -p

  2. Totally works. i just had to replace with version 57.33 as Woltis noted. Also, listed some dependency challenges with needing mysql-community-client as well as mysql-client. thanks so much for this!.

  3. Use sudo apt install -f mysql-client=5.7.33-1ubuntu18.04 mysql-community-client=5.7.33-1ubuntu18.04 mysql-community-server=5.7.33-1ubuntu18.04 mysql-server=5.7.33-1ubuntu18.04
