How to Setup and Connect MySQL to EC2 Instance from Ubuntu

MYSQL is a famous open-source relational database management system that provides scalable and easy-to-use function sets. It uses a relational DB and Structured Query Language (SQL) for managing its data. This tutorial describes a basic MySQL installation and setup; later we will connect MySQL to EC2 instance from Ubuntu. Once done with the basics, we will create a user for our database.

What is AWS EC2?

AWS EC2 – AWS Elastic Compute Cloud is one of the most famous Amazon services that provides the ability of running the app on the public cloud. It offers safe, reliable, and resizable cloud capacity with minimum obstacles.

I assume that you are quite familiar with Amazon EC2 and MySQL to proceed with MySQL Setup in EC2 Ubuntu Instance.

Prerequisites

To get started with the tutorial for setting up MySQL in EC2 Ubuntu Instance, please make sure of the following prerequisites-

⦿ Create EC2 Ubuntu Instance in AWS Account
⦿ Connect EC2 Instance using SSH or Putty

Now, let’s move towards how to set up and connect MySQL to EC2 Instance Ubuntu.

6 Steps to Setup and Connect MySQL to EC2 Instance from Ubuntu

Step 1: Update System Packages and Install MySQL

Run install update for your server system packages

Now, install MySQL using the below command to install the latest MySQL.

After successful installation of mysql-server, we can check the MySQL version by using this command-

Step 2: Configure MySQL Installation

To configure the installation of MySQL, run the security script with sudo to run as the root user- the super privileged user.

Run the below command-

When we install MySQL for the first time, we will be prompted to create a new password.

If you are getting an error while setting up the password, check the temporary password in the log file.

Use the below command to get a temporary password.

We can find something like this:

Step 3: Login into MySQL and Create a User

Use the below command to login into MySQL:

The command will log in to MySQL using the root user. Once you are logged in, create a user in the MySQL database using these commands:

Step 4: Grant Access Privileges to User

Now, to grant access privileges to this newly created user, use this command:

Once this is done, run this command,

Step 5: Connect User with MySQL

Now you can use this user to connect with MySQL like this:

Once prompted for a password, provide the password, and you will be connected.

Trick: If you want to store passwords for that user, so prompting will not annoy us, do these things.
Create .my.cnf file inside /home/Ubuntu path

Write this command:

Write these lines in that file and save.

Now, whenever you want to connect, you can use this .my.cnf file like this, and no need to provide a password.

This file is generally needed when running the CI/CD pipeline and connecting to another server’s MySQL server.

Step 6: Restart MySQL Service

To affect these changes, restart the MySQL service by following commands:
to check the status of MySQL service:

Now, if it is in “Running” mode, then restart it using the below command:

This will restart the service and will reflect our changes.

Now, your MySQL has been set up in your Ubuntu Ec2 Instance.
