Are you looking for a guide to help you install MySQL 5.7 on CentOS 8 / RHEL 8 Linux server / Workstation?. The CentOS / RHEL 8 AppStream repository only contain MySQL 8.0 packages. Not all applications have support for MySQL 8, e.g Jira as of this writing require MySQL 5.7 and below. How then can you install MySQL 5.7 on CentOS 8 / RHEL 8?.

MySQL is a very popular open-source relational database management system. It is being developed by Oracle Corporation – Company behind Oracle Database. With its proven reliability, performance, and ease-of-use, MySQL has become the leading database choice for web-based applications.

Follow the next steps to have a running MySQL 5.7 Server on CentOS 8 / RHEL 8 system.

Step 1: Add MySQL repository

Disable MySQL default AppStream repository:

sudo dnf remove @mysql
sudo dnf module reset mysql && sudo dnf module disable mysql

There is no MySQL repository for EL 8, so we’ll use EL 7 repository instead. Create a new repository file.

sudo vi /etc/yum.repos.d/mysql-community.repo

Paste below data into the file.

name=MySQL 5.7 Community Server

name=MySQL Connectors Community

name=MySQL Tools Community

Step 2: Install MySQL 5.7 on CentOS 8 / RHEL 8

Once the repository has been added, now install MySQL 5.7 on CentOS 8 / RHEL 8.

Disable MySQL 8 repository:

sudo dnf config-manager --disable mysql80-community

Then enable channel for MySQL 5.7.

sudo dnf config-manager --enable mysql57-community

Then install MySQL 5.7 on CentOS 8 / RHEL 8:

sudo dnf install mysql-community-server

Press y to start the installation.

2.3 – Start MySQL Secure Installation to change the root password, Disallow root login remotely, remove anonymous users and remove test database.

$ sudo mysql_secure_installation
Securing the MySQL server deployment.
Enter password for user root:

1 row in set (0.00 sec)

mysql> QUIT

2.5 – Create a test database and user:

mysql> CREATE DATABASE test_db;
Query OK, 1 row affected (0.09 sec)

mysql> CREATE USER 'test_user'@'localhost' IDENTIFIED BY "Strong34S;#";
Query OK, 0 rows affected (0.04 sec)

mysql> GRANT ALL PRIVILEGES ON test_db.* TO 'test_user'@'localhost';
Query OK, 0 rows affected (0.02 sec)

Query OK, 0 rows affected (0.02 sec)

This test database and user can be dropped by running:

mysql> DROP DATABASE test_db;
Query OK, 0 rows affected (0.14 sec)

mysql> DROP USER 'test_user'@'localhost';
Query OK, 0 rows affected (0.11 sec)

mysql> show databases;
| Database           |
| information_schema |
| mysql              |
| performance_schema |
| sys                |
4 rows in set (0.01 sec)

mysql> QUIT

To allow for remote connections, allow port 3306 on the firewall

sudo firewall-cmd --add-service=mysql --permanent
