MySQL is a widely used, open-source relational database management system. It is an essential component for many applications and websites. This guide will walk you through the process of installing MySQL on a Linux system using the YUM package manager.
This guide is applicable to CentOS, RHEL, and other Linux distributions that use YUM as their package manager.
Step 1: Update YUM Repository
Before installing MySQL, it is a good practice to update the YUM repository to ensure that you are installing the latest available version:
sudo yum update
Step 2: Install MySQL Community Repository
By default, MySQL is not available in the standard YUM repositories. You need to install the MySQL Community Repository to access MySQL packages:
sudo yum install https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm
Please note that the URL may change with newer releases. You can find the latest MySQL Community Repository package for your distribution from the official MySQL website.
Step 3: Install MySQL Server
Now that the MySQL Community Repository is installed, you can use YUM to install the MySQL server package:
sudo yum install mysql-server
Example:
sudo yum install mysql-server Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * addons: ftp.oss.eznetsols.org * base: ftp.oss.eznetsols.org * epel: bali.idrepo.or.id * extras: ftp.oss.eznetsols.org * updates: ftp.oss.eznetsols.org Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package mysql-server.x86_64 0:5.0.77-4.el5_5.4 set to be updated --> Processing Dependency: mysql = 5.0.77-4.el5_5.4 for package: mysql-server --> Processing Dependency: perl-DBD-MySQL for package: mysql-server --> Running transaction check ---> Package mysql.x86_64 0:5.0.77-4.el5_5.4 set to be updated ---> Package perl-DBD-MySQL.x86_64 0:3.0007-2.el5 set to be updated --> Finished Dependency Resolution Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Installing: mysql-server x86_64 5.0.77-4.el5_5.4 updates 9.8 M Installing for dependencies: perl-DBD-MySQL x86_64 3.0007-2.el5 base 148 k Updating for dependencies: mysql x86_64 5.0.77-4.el5_5.4 updates 4.8 M Transaction Summary ================================================================================ Install 2 Package(s) Upgrade 1 Package(s) Total download size: 15 M Is this ok [y/N]: y Downloading Packages: (1/3): perl-DBD-MySQL-3.0007-2.el5.x86_64.rpm | 148 kB 00:17 (2/3): mysql-5.0.77-4.el5_5.4.x86_64.rpm | 4.8 MB 06:40 (3/3): mysql-server-5.0.77-4.el5_5.4.x86_64.rpm | 9.8 MB 15:12 -------------------------------------------------------------------------------- Total 11 kB/s | 15 MB 22:20 Running rpm_check_debug Running Transaction Test Finished Transaction Test Transaction Test Succeeded Running Transaction Updating : mysql 1/4 Installing : perl-DBD-MySQL 2/4 Installing : mysql-server 3/4 Cleanup : mysql 4/4 Installed: mysql-server.x86_64 0:5.0.77-4.el5_5.4 Dependency Installed: perl-DBD-MySQL.x86_64 0:3.0007-2.el5 Dependency Updated: mysql.x86_64 0:5.0.77-4.el5_5.4 Complete!
Step 4: Start and Enable MySQL Server
After the installation is complete, start the MySQL server and enable it to start automatically on system boot:
sudo systemctl start mysqld sudo systemctl enable mysqld
Step 5: Secure MySQL Installation
Run the mysql_secure_installation script to perform basic security settings such as setting a root password, removing anonymous users, disabling remote root login, and removing the test database:
sudo mysql_secure_installation
Follow the prompts and answer the questions accordingly to complete the MySQL security setup.
