Requirements:

• MySQL 8.0
• CentOS 7
• Virtual Machine or Physical Server/Desktop
• Internet on the CentOS Server

Installation:

Create an operating system user named as “mysql” by logging in to the operating system root user and add the user to the “sudo” list.

# useradd mysql
# passwd mysql
# usermod -aG wheel mysql

Install the wget package to download the mysql yum repository.

# yum install wget

Connect to the mysql user by switch user “su” command or connecting from a new SSH session.

# su - mysql

Add the MySQL Yum repository to your system’s repository list. Got to the Download MySQL Yum Repository page (https://dev.mysql.com/downloads/repo/yum/) in the MySQL Developer Zone. Select and download the release package for your platform by the following command. In this case it will be “mysql80-community-release-el7-3.noarch.rpm”.

$ sudo wget https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm

Install the downloaded release package with the following command.

$ sudo yum localinstall mysql80-community-release-el7-3.noarch.rpm

Check that the MySQL Yum Repository has been successfully added by the following command.

$ yum repolist enabled | grep "mysql.*-community.*"

Install MySQL by the following command.

$ sudo yum install mysql-community-server

When successfully  done start the mysql server with the following command.

$ sudo service mysqld start

You can check the status of the mysql server with the following command.

$ sudo service mysqld status

A superuser account ‘root’@’localhost is created. A password for the superuser is set and stored in the error log file. Show the password by the following command:

$ sudo grep 'temporary password' /var/log/mysqld.log

Connect to the mysql server with root user created with the temporary password above and change the root password immediately as a best practice.

$ mysql -u root -p
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MySQL@!098';

 

Note: You can install the mysql database server by using operating system root user but for security concern it is not recommended.
