MySQL is a free and open source software used to manage databases on a computer. MySQL can be installed on many different operating system platforms such as Windows, Linux and Mac OS X. In this article, we will guide you to install MySQL in CentOS 7 using command line on server.
What you need to prepare before installing:
– Root access to your server.
– CentOS 7 was installed on your server.
Step 1 – Download and prepare the MySQL repository
To start, you should connect to your server via SSH and prepare the commands below for use in the command line.
First, you need to check if the system is up-to-date and up-to-date if needed. Type the following command:
sudo yum update
Waiting for system updates. Then install MySQL repositories. You can find the latest version here: https://dev.mysql.com/downloads/repo/yum/). Type the following command:
wget http://mysql.com/get_mysql57-community-release-el7-9.noarch.rpm
Once loaded, you will see that the .rpm file has been saved.
Now you can prepare the repository and install MySQL packages from it. Type the command:
sudo rpm -Uvh mysql57-community-release-el7-9.noarch.rpm
You will likely see the same result:
When you see that it reaches 100%, you will be able to start installing MySQL CentOS 7. Detailed instructions will be in the next step.
Step 2 – Install MySQL on the server
Now you can install MySQL right from this command line:
sudo yum install mysql-server
A list of files will be given and you will receive a confirmation message to download them. Type y, and then press ENTER to continue.

If you see the word “Complete!” At the bottom of the page, means that MySQL has been successfully installed on the server.
Step 3 – Run MySQL and see if it works
MySQL is not booted after installation, so you need to boot with the following command:
sudo systemctl start mysqld
Wait a few seconds. You will not receive a response to MySQL startup, so check the following:
sudo systemctl status mysqld
The result of the MySQL status will be as follows:
If you see MySQL active and running as shown above, you have successfully installed MySQL and have started MySQL on the server.
Summary
You have completely installed MySQL on CentOS 7 server. From now on you can store databases on it to manage them or using them to build websites or web applications.
