So, let’s roll up our sleeves and dive right in!
Why Choose MySQL or MariaDB?
Before we jump into the installation process, let’s take a moment to explore why you might want to install MySQL or MariaDB in the first place.
What are MySQL and MariaDB?
Both MySQL and MariaDB are open-source relational database management systems (RDBMS) that use Structured Query Language (SQL) for managing and accessing data. Think of them as the backbone of your application, helping it to store and retrieve data efficiently.
Key Features
- High Performance: Both systems are designed for speed and efficiency, ensuring your applications run smoothly.
- Security: They come with robust security features, including user authentication and access controls.
- Community Support: A large community of developers and users is available to help solve issues and share knowledge.
While MySQL is the more established name, MariaDB was created as a fork of MySQL and aims to maintain compatibility while adding additional features. Many users prefer MariaDB for its performance improvements and open-source nature. The choice depends on your needs, but for this guide, we’ll cover both installation processes since they’re quite similar.
Prerequisites for Installation
Before installing MySQL or MariaDB, there are a few prerequisites you should ensure are in order:
- Ubuntu System: You need to have a running instance of Ubuntu (20.x or 22.x). You can use either a local machine, a virtual machine, or a cloud server.
- Sudo Privileges: You’ll need administrative access to your Ubuntu machine. This means you will execute commands that may require higher permissions using the ‘sudo’ command.
- Internet Connection: Having an internet connection ensures that you can download the necessary packages and updates.
Updating Your Package Index
Before diving into the installation, it’s always a good practice to ensure your package index is up to date. This ensures that you get the latest versions of the software available in the repositories. Here’s how you can do it:
- Open your terminal in Ubuntu.
- Type the following command and hit Enter:
sudo apt updateThis command refreshes the package manager’s list of available packages and their versions, so you can install them smoothly.
Installing MySQL on Ubuntu
Now that your package index is updated, let’s go ahead with installing MySQL:
- To install MySQL, run the following command:
sudo apt install mysql-serverOnce executed, the installer will start downloading MySQL and any required dependencies. It may take a few minutes, depending on your internet speed.
Securing MySQL Installation
Once the installation completes, it’s essential to run a security script that comes pre-installed with MySQL. This will help in securing your installation:
- Run the security script by entering:
sudo mysql_secure_installationFollow the prompts to configure security settings, including setting a root password and removing test databases. This step is critical in preventing unauthorized access to your MySQL server.
Installing MariaDB on Ubuntu
If you opted for MariaDB instead, the installation process is quite similar and straightforward:
- Install MariaDB server by executing the following command:
sudo apt install mariadb-serverLike MySQL, this will download and install the server along with required dependencies.
Securing MariaDB Installation
Similar to MySQL, it’s crucial to run a security script for MariaDB after installation:
- Run the command:
sudo mysql_secure_installationThis will guide you through the steps to secure your installation, ensuring that your database is safe from vulnerabilities.
Starting and Enabling MySQL/MariaDB Service
Now that you have installed your chosen database server, it’s essential to start and enable the service so it runs automatically on system boot.
- To start the service, use the following command:
sudo systemctl start mysql # For MySQL
sudo systemctl start mariadb # For MariaDBTo enable the service to start at boot, use:
sudo systemctl enable mysql # For MySQL
sudo systemctl enable mariadb # For MariaDBConnecting to MySQL/MariaDB
Once your database server is up and running, you can start interacting with it. Here’s how you can connect:
- Open your terminal and connect to the database using the command:
sudo mysqlFor MariaDB, the command is the same. This command connects you to the database as the root user.
Creating a New Database
Once connected, you might want to create a new database. Here’s a quick way to do that:
CREATE DATABASE mydatabase;Replace “mydatabase” with your desired database name.
Real-world Application: A Case Study
Let’s consider a small startup looking to launch its first web application. They opted for MariaDB due to its performance and cost-effectiveness. Following this installation guide, they set up their database successfully, enabling them to launch their application ahead of schedule. This timing not only impressed their initial clients but also opened doors to future funding opportunities. This case shows how vital correct database setup can be to a business’s success!
