How To Install MySQL on Ubuntu 18.04 LTS

Install MySQL on Ubuntu 18.04 LTS

In this tutorial, we will show you how to install MySQL on Ubuntu 18.04 LTS server. For those of you who didn’t know, MySQL is a relational database management system (RDBMS) that runs as a server providing multi-user access to a number of databases. The MySQL source code is freely available because it was originally developed as freeware. MySQL is written in C and C++ and is compatible with all major operating systems. MySQL can be used for a variety of applications but is most commonly found on web servers.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of MySQL 8.0 on a Ubuntu 18.04 (Bionic Beaver) server.

Prerequisites

  • A server running one of the following operating systems: Ubuntu 18.04 (Bionic Beaver).
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install MySQL on Ubuntu 18.04 LTS Bionic Beaver

Step 1. First, make sure that all your system packages are up-to-date by running the following apt-get commands in the terminal.

sudo apt-get update
sudo apt-get upgrade

Step 2. Installing MySQL on Ubuntu 18.04 LTS.

In the first step, we will now set up the MySQL official repository on the system:

wget https://dev.mysql.com/get/mysql-apt-config_0.8.10-1_all.deb

Then run the commands below to install:

sudo dpkg -i mysql-apt-config_0.8.10-1_all.deb

The MYSQL installer will prompt you to select the MySQL repository. Based on your selection, the installer will configure repositories on the system to receive the appropriate version of MySQL.

Now that the repository is installed, run the commands below to install:

apt install mysql-server mysql-client

During the installation, you should be prompted to create and confirm a MySQL root password.

Once complete, you can verify MySQL 8.0 is installed by running the below command:

systemctl status mysql
systemctl start mysql
systemctl enable mysql

After the installation of MySQL is complete, you may need to secure your new MySQL. By default, MySQL is not hardened. You can secure MySQL using the mysql_secure_installation script. you should read and below each step carefully which will set a root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MySQL:

mysql_secure_installation

Configure it like this:

- Set root password? [Y/n] y
- 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

To log in to MySQL, use the following command (note that it’s the same command you would use to log into a MySQL database):

mysql -u root -p

One of the most important things when running MySQL on a production server is to get the most out of its performance. If you are a beginner and you do not know how to tune your MySQL server, you can start with a program called MySQLTuner. It will help you to analyze your server and to tune MySQL for better overall performance.

Congratulations! You have successfully installed MySQL. Thanks for using this tutorial for installing MySQL 8.0 server in Ubuntu 18.04 Bionic Beaver system. For additional help or useful information, we recommend you check the official MySQL website.
