MySQL is a free and opensource database server which is very popular in the opensource community. MySQL is used by a lot of applications and companies like Facebook, Google, etc. In this tutorial, we will learn how to install MySQL into deb or apt-based distributions like Ubuntu, Debian, Mint, and Kali. This guide can be used for other deb or apt based distributions too.
Update Repository Information
It is not a requirement but a best practice to update repository information which will provide us the newest information about MySQL.
$ sudo apt update
Install MySQL Server From Apt Repository
MySQL Server application is named as mysql-server as package name. We can use apt or apt-get in order to install mysql-server package like below. We can also use -y option in order to automatically accept conformation.
$ sudo apt install mysql-server
Download MySQL Server Binary
Another way to install MySQL is from a binary installation file. We can download MySQL binary from official download site mysql.com. But keep in mind that different versions of MySQL Server are provided with different licenses and costs. We will use community version for Ubuntu which can be listed from the following link.
https://dev.mysql.com/downloads/mysql/
and we will download the deb package with wget.
$ wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-server_8.0.11-1ubuntu18.04_amd64.deb-bundle.tar
Install MySQL Binary Deb Package
After the download is completed we will first extract the tar archive like below.
$ tar xvf mysql-server_8.0.11-1ubuntu18.04_amd64.deb-bundle.tar
and we will install the mysql-community-server_8.0.11-1ubuntu18.04_amd64.deb package with dpkg like below.
$ sudo dpkg -i mysql-community-server_8.0.11-1ubuntu18.04_amd64.debSecure MySQL Server Installation
Security is an important part of today’s IT systems. We can make MySQL more secure by using mysql_secure_installation hardening script. This will run some commands which will change MySQL configuration and harden it. This script will start by asking root password and then ask some questions about security.
$ sudo mysql_secure_installation
Show MySQL Service or Daemon Status
After the installation is completed and secured we can list the status of the MySQL server. We will use systemctl command with status option to list whether the MySQL daemon is working or not.
$ systemctl status mysql
As we can see the daemon is running properly.
Start MySQL Service/Daemon/Server
If the MySQL service is not started or stopped with a reason we can start MySQL service with start option like below.
$ systemctl start mysqlStop MySQL Service/Daemon/Server
If we need to stop the MySQL daemon we can use stop option. This can be useful to apply a new configuration by stopping and starting the service.
$ systemctl stop mysqlTest MySQL Server By Logging In
We can test the MySQL server by connecting to the service console with mysql command. We also need to provide the username and the password like below.
$ mysql -u root -p
