How To Install MySQL 8 on Amazon Linux 2

By Posted on 260 views

SQL stands for “structured query language” and it makes up the name MySQL, which is the combination of My and SQL. My is the name of  MySQL’s co-founder, Monty Widenius daughter. MySQL is an open source database management system created primarily for the management of relational databases. For commercial use cases you can buy a license from Oracle for premium support.

In this article I’ll walk you through the installation of MySQL 8.0 on Amazon Linux 2 Server running on AWS Cloud or as a Virtual Machine somewhere in your data center. If you need a detailed article on the new features of MySQL 8, checkout the official release notes page.

Install MySQL 8 on Amazon Linux 2

Amazon Linux is a derivative of CentOS 7 Linux server with few extra repositories and packages for improved performance and integrations with other AWS cloud services. You can check the release of your server by running the following command in the terminal.

$ cat /etc/os-release
NAME="Amazon Linux"
VERSION="2"
ID="amzn"
ID_LIKE="centos rhel fedora"
VERSION_ID="2"
PRETTY_NAME="Amazon Linux 2"
ANSI_COLOR="0;33"
CPE_NAME="cpe:2.3:o:amazon:amazon_linux:2"
HOME_URL="https://amazonlinux.com/"

Step 1: Add MySQL Yum Repository to Amazon Linux 2

First, we need to add the MySQL Yum repository to our Amazon Linux 2 server’s repository list. This operation is only done once and provides all MySQL package versions repositories.

Install an RPM repository package by running the commands below:

sudo yum install https://dev.mysql.com/get/mysql80-community-release-el7-5.noarch.rpm

Hit the y key in your keyboard when prompted to start the installation.

Step 2: Install MySQL 8 on Amazon Linux 2

Once the repository has been added, install MySQL 8 server packages on Amazon Linux 2.

sudo amazon-linux-extras install epel -y
sudo yum -y install mysql-community-server

A number of dependencies are installed in the process.

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) : y
Success.


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) : y
 - Dropping test database...
Success.

 - Removing privileges on test database...
Success.

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!

You can update root password anytime from MySQL shell.

$ mysql -uroot -p
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '[email protected]!';

The Password Policy is requires:

  • At least one uppercase letter
  • At least one lowercase letter
  • At least one digit
  • At least one special character
  • Total password length is at least 8 characters.

You have installed MySQL 8 server successfully on Amazon Linux 2 and ready to roll
