In this tutorial we will show you how to install and configuration of MySQL on CentOS 8. 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 through the step by step installation MySQL Server on a CentOS 8 server.
Install MySQL on CentOS 8
Step 1. First let’s start by ensuring your system is up-to-date.
Step 2. Install MySQL on CentOS 8.
You need to enable repository package of MySQL on your system:
dnf install wget wget https://dev.mysql.com/get/mysql80-community-release-el8-1.noarch.rpm rpm -ivh mysql80-community-release-el8-1.noarch.rpm
Next, Use dnf command install the latest version of MySQL:
dnf install mysql-server
Once complete, you can verify MySQL is installed by running the below command:
sudo systemctl status mysql sudo systemctl start mysql sudo systemctl status mysql
Step 3. Securing 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 steps carefully which will set root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MySQL:
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 into 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 performances. 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 performances.
