How To Install MySQL Database on Ubuntu 18.04 LTS
On this short guidance we will explain how to install MySQL on Ubuntu 18.04 TLS. Login to the database and do execute a simple query.
Introduction
MySQL is the most popular open source SQL database management system with around 6 million installations worldwide. MySQL was built and maintenance by MySQL AB before Sun Microsystems Inc take acquisition action against MySQL AB on January 16, 2008. And finnaly one year later, Oracle’s turn to acquire Sun Microsystems Inc. Since then, since then MySQL has officially become a family of Oracle products.
MySQL is very popular in web applications such as MediaWiki (software used by Wikipedia and similar projects) and PHP-Nuke and functions as a database component in LAMP. Popularity as a web application due to its proximity to the popularity of PHP, so it is often referred to as Dynamic Duo. In this short tutorial, we will explain how to install mysql on the Ubuntu 18.04 LTS operating system.
MySQL Installation On Ubuntu
The MySQL installation process will consist of several stages, namely:
Prerequisite
Before we are going to install MySQL database on Ubuntu 18.04 LTS, we have to prepare the environment first as mentioned below :
- Ubuntu 18.04 LTS System
- root or ordinary account with sudo privilege
- Sufficient disk space
Step 1: Installing MySQL on Ubuntu 18.04
On this tutorial, we will install MySQL version 5.7. To install MySQL on Ubuntu server, we have to add MySQL repository to our system first, after that we just install it.
1. Updating Local Repository
By updating local repository, we will update all repository to the latest version. To do this task, we will use the following command line :
$ sudo apt-get update
The output will be shown below :
ramans@ubuntu:~$ sudo apt-get update [sudo] password for ramans: Get:1 http://security.ubuntu.com/ubuntu bionic-security InRelease [88.7 kB] Hit:2 http://us.archive.ubuntu.com/ubuntu bionic InRelease Get:3 http://us.archive.ubuntu.com/ubuntu bionic-updates InRelease [88.7 kB] Get:4 http://us.archive.ubuntu.com/ubuntu bionic-backports InRelease [74.6 kB] Fetched 252 kB in 4s (58.7 kB/s) Reading package lists... Done
2. Installing MySQL Database Engine
After updating local repository, we will do the installation by submitting command line :
$ sudo apt-get install mysql-server
The output will be shown below :
ramans@ubuntu:~$ sudo apt-get install mysql-server Reading package lists... Done Building dependency tree Reading state information... Done The following package was automatically installed and is no longer required: libllvm8 Use 'sudo apt autoremove' to remove it. The following additional packages will be installed: libaio1 libevent-core-2.1-6 libhtml-template-perl mysql-client-5.7 mysql-client-core-5.7 mysql-common mysql-server-5.7 mysql-server-core-5.7 Suggested packages: libipc-sharedcache-perl mailx tinyca The following NEW packages will be installed: libaio1 libevent-core-2.1-6 libhtml-template-perl mysql-client-5.7 mysql-client-core-5.7 mysql-common mysql-server mysql-server-5.7 mysql-server-core-5.7 0 upgraded, 9 newly installed, 0 to remove and 17 not upgraded. Need to get 20.5 MB of archives. After this operation, 161 MB of additional disk space will be used. Do you want to continue? [Y/n] Y ... Renaming removed key_buffer and myisam-recover options (if present) Created symlink /etc/systemd/system/multi-user.target.wants/mysql.service → /lib/systemd/system/mysql.service.

Processing triggers for man-db (2.8.3-2ubuntu0.1) ... Processing triggers for ureadahead (0.100.0-21) ...
After the installation is completed, the MySQL service will start automatically. We will verify it by submitting command line :
$ systemctl status mysql.service
The output will be shown below :
ramans@ubuntu:~$ systemctl status mysql.service
● mysql.service - MySQL Community Server
Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: enabled)

Sep 26 04:40:02 ubuntu systemd[1]: Starting MySQL Community Server...
Sep 26 04:40:02 ubuntu systemd[1]: Started MySQL Community Server.
We can also verify the MySQL installation by querying the version, by submitting command line :
$ mysql --version
The output will be shown below :
ramans@ubuntu:~$ mysql --version mysql Ver 14.14 Distrib 5.7.27, for Linux (x86_64) using EditLine wrapper
Step 2: Securing MySQL Server
MySQL is equipped with scripts for handling security issues. For fresh installation, we are recommended to run a script that can increase the security level of the MySQL database that we have had installed. To do this task, we just type the command line :
$ sudo mysql_secure_installation
The output will be as following :
ramans@ubuntu:~$ sudo mysql_secure_installation Securing the MySQL server deployment. Connecting to MySQL using a blank 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 file Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 1 Please set the password for root here. New password: Re-enter new password: Estimated strength of the password: 100 Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : Y By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? (Press y|Y for Yes, any other key for No) : N ... skipping. Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y Success. By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? (Press y|Y for Yes, any other key for No) : N ... skipping. Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y Success. All done!
Step 3: Accessing MySQL On Ubuntu 18.04
On this sub section, we will try to login to our MySQL databases. When we are running MySQL 5.7 (and later), by default the root user is authenticated by the auth_socket plugin. We will login and list all database which was formed since installation. To do so, we just type the command line :
$ sudo mysql
The output will be shown below:
ramans@ubuntu:~$ sudo mysql Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 4 Server version: 5.7.27-0ubuntu0.18.04.1 (Ubuntu) Copyright (c) 2000, 2019, Oracle and/or its affiliates. All rights reserved.

Conclusion
On this article, we have shown you how to install MySQL version 5.17 on Ubuntu 18.04 LTS operating system. Then we also try to access the database which was we installed. I hope this tutorial will be helpful for anyone.
