MySQL is the most popular, free and open source database system, and can be installed easily as a part of any popular LEMP stack. To manage its data, MySQL uses the relational database & SQL (or Structured Query Language).
CentOS 7 generally prefer MariaDB, fork of MySQL that is managed by an original developer and made as the replacement for MySQL. Suppose you run the program yum install mysql at CentOS 7, MariaDB gets installed instead of MySQL. Suppose you are thinking about MySQL and MariaDB, then MariaDB will work seamlessly for MySQL, thus unless you have the specific case for the MySQL, you need to learn the complete process of installation of MySQL on Centos OS from the given guide.
Chances are you are use Linux in its forms. It is possible that you are using this to deploy the containers, virtual machines, cloud applications, or other incarnation of an open source platform. Irrespective of how you make use of Linux, the probability that you will depend on the database is quite high. And suppose your deployments may depend on the database, MySQL is the strong candidate. If your platform is CentOS, then MySQL is accessible for a simple installation.
Let me take you through this process of installation of MySQL on Centos OS that is a bit different than installing at other platforms. I am demonstrating on a Minimal version of the CentOS 7.
MySQL is generally used for the server and web applications. But, MySQL is now not available in CentOS’s repositories & MariaDB has actually become its default database system. MariaDB is the drop-in replacement of MySQL and will be enough if you need the database system. You know more about it you will have to go through MariaDB in CentOS guide for complete installation instructions.
Suppose you nonetheless want MySQL, this guide can introduce you on how to install, manage and configure this on the Linode running CentOS 7. Bit MySQL databases will need a huge amount of memory. And for this reason, it is recommended using the high memory Linode in such setups.
Prerequisites To Follow
Before you start the tutorial, ensure you’re logged in your server with the user account and sudo privileges and with the user. It’s good to run the administrative commands as a sudo user in place of root, in case you do not have the sudo user in your system then you can make one by following the instructions.
Like we mentioned in our introduction MySQL isn’t available in a default CentOS 7 repositories thus we have to install these packages from MySQL Yum Repository. For following sections, we are going to show you the complete procedure on how to install the MySQL 8.0 & MySQL 5.7.
You must install just one MySQL system on your CentOS 7. Suppose you aren’t sure which version you need to install then consult your applications documentation you will use on the server.
Way to go
Congratulations: Now, you have the working MySQL server at CentOS 7 platform. You are ready to start building databases and utilizing it them for different deployments.
