MySQL is a renowned open-source relational database management system that is vital for many server applications. It runs on multiple system platforms, including Windows, Linux and MacOS. Apache and PHP are complementary, making them a popular choice for developers when creating websites and online applications. Installing MySQL on Ubuntu is straightforward and can be accomplished with a few steps. In this guide, we will provide detailed instructions on how to accomplish this.
To install MySQL on Ubuntu, first, you need to update the package lists for upgrades and new package installations. Open Terminal and type the following command:
sudo apt-get update
Once your system’s package list is updated, proceed to install MySQL. Type in this command in the Terminal:
sudo apt-get install mysql-server
During the installation process, you will be asked to create a root (administrative) password.
Once MySQL is installed, it is recommended to run a security script that comes pre-installed with MySQL. It removes some default settings and locks down access to your database system. Type the following command to initiate the script:
Prompts will appear at which you must enter ‘Y’ or ‘Yes’. These include setting up the Validate Password Plugin, changing the root password, removing anonymous users, disallowing root login remotely, removing test databases and access to them, and reloading privilege tables.
Testing MySQL Installation
After securing MySQL, it is essential to cross-check whether the installation is successful. Type the following command:
systemctl status mysql.service
If MySQL is running correctly, then your installation process was successful.
