1. Introduction
In this article, we will provide a comprehensive guide on installing MySQL on Ubuntu. We'll cover the prerequisites, installation steps, and how to secure your MySQL installation. By the end of this guide, you'll have a working MySQL database on your Ubuntu system.
2. Prerequisites
Before proceeding with the installation, there are a few prerequisites you need to fulfill:
2.1. Ubuntu Installation
Ensure that you have a working installation of Ubuntu on your system. If not, download the latest version of Ubuntu from the official website and follow the installation instructions.
2.2. Update and Upgrade
It's always a good practice to update and upgrade your Ubuntu system before installing any new software. Open the terminal and run the following commands:
sudo apt update
sudo apt upgrade
3. Installing MySQL
Now that your system is up to date, let's proceed with the installation of MySQL.
3.1. Step 1: Adding Repository
To install the latest version of MySQL, we'll add the MySQL APT repository to our system. Open the terminal and run the following commands:
wget https://dev.mysql.com/get/mysql-apt-config_0.8.17-1_all.deb
sudo dpkg -i mysql-apt-config_0.8.17-1_all.deb
sudo apt update
During the installation, you'll be prompted to choose the MySQL version and other options. Select the desired version and proceed with the installation.
3.2. Step 2: Installing MySQL
After adding the repository, we can now install MySQL using the following command:
sudo apt install mysql-server
During the installation, you'll be prompted to set a root password for MySQL.
3.3. Step 3: Configuring MySQL
Once the installation is complete, run the following command to configure MySQL:
sudo mysql_secure_installation
This command will guide you through a series of prompts to secure your MySQL installation. It includes steps such as removing anonymous users and disallowing remote root login.
4. Securing MySQL
Securing your MySQL installation is crucial to protect your data and prevent unauthorized access. Here are some essential steps to secure MySQL:
4.1. Step 1: Updating Root Password
It's recommended to update the default root password after the initial installation. Run the following command to change the root password:
sudo mysql
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'new_password';
FLUSH PRIVILEGES;
Replace 'new_password' with your desired password.
4.2. Step 2: Removing Anonymous Users
MySQL comes with anonymous user accounts that can be potential security risks. Run the following command to remove these users:
sudo mysql
DELETE FROM mysql.user WHERE User='';
FLUSH PRIVILEGES;
4.3. Step 3: Disabling Remote Root Login
To enhance security, it's advisable to disable remote root login. Open the MySQL configuration file using the following command:
sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf
Find the line that says bind-address and change its value to 127.0.0.1. Save the file and restart MySQL for the changes to take effect:
sudo systemctl restart mysql
5. Conclusion
Congratulations! You have successfully installed and secured MySQL on your Ubuntu system. You can now start using MySQL for your projects and applications.
