Introduction
Greetings, fellow tech enthusiasts! Whether you are a seasoned sysadmin or a newbie, you will find this guide helpful in setting up your own Ubuntu web server. Ubuntu is a popular Linux distribution for web servers, owing to its stability, security, and ease of use. In this article, we will walk you through the steps to configure your Ubuntu server to host websites and web applications.
Before we dive into the technical details, let us first define what a web server is. Simply put, a web server is a computer application that serves web content over the internet. This content can range from static HTML pages to dynamic web applications that interact with databases and other web services. A web server can be accessed by users through their web browsers using HTTP or HTTPS protocols.
In this guide, we will use the latest version of Ubuntu LTS (Long-Term Support), which is version 12.04. LTS releases are supported for five years and are recommended for production environments. Let’s get started!
Setting up Ubuntu Web Server 12.04
Step 1: Installing Ubuntu Server
The first step in setting up your web server is installing Ubuntu server on your machine. You can download the ISO image from the official Ubuntu website and burn it to a DVD or USB drive. Boot your machine from the installation media and follow the prompts to install Ubuntu server. Make sure to choose the “Install Ubuntu Server” option and configure the network settings as required.
Once the installation is complete, login to your new Ubuntu server using the credentials you set during the installation process.
Step 2: Updating and Securing Ubuntu Server
Before we proceed with installing and configuring the web server, it is important to update and secure your Ubuntu server. Run the following commands to update the system packages and install essential security packages:
Command |
Description |
|---|---|
sudo apt-get update |
Updates the package list |
sudo apt-get upgrade |
Upgrades the system packages |
sudo apt-get install ufw |
Installs the Uncomplicated Firewall |
sudo ufw enable |
Enables the firewall |
Step 3: Installing and Configuring Web Server
Now that we have updated and secured our Ubuntu server, we can proceed with installing and configuring the web server. In Ubuntu, the default web server is Apache, which is a widely used and well-documented web server. Run the following command to install Apache:
sudo apt-get install apache2
Once the installation is complete, you can test if Apache is working by opening a web browser and navigating to http://localhost/. If you see the Apache2 Ubuntu Default Page, then the web server is working fine.
Step 4: Configuring Virtual Hosts
Virtual Hosts allow you to host multiple websites on a single server. To configure Virtual Hosts, create a new configuration file for each website in the /etc/apache2/sites-available/ directory. You can use the following template:
<VirtualHost *:80>ServerAdmin webmaster@yourwebsite.comServerName yourwebsite.comServerAlias www.yourwebsite.comDocumentRoot /var/www/yourwebsite.com/public_htmlErrorLog ${APACHE_LOG_DIR}/error.logCustomLog ${APACHE_LOG_DIR}/access.log combined</VirtualHost>
Edit the above template with your website details and save the file with a unique name. Then, enable the site by running the following command:
sudo a2ensite yoursite.conf
Restart Apache for the changes to take effect:
sudo systemctl restart apache2
Step 5: Installing MySQL Database
Most web applications require a database for storing and retrieving data. In Ubuntu, the default database server is MySQL. Run the following command to install MySQL:
sudo apt-get install mysql-server
During the installation process, you will be asked to set a root password for MySQL.
Step 6: Securing MySQL Server
It is important to secure your MySQL server by setting a strong password for the root user and removing anonymous users and test databases. Run the following command to start the MySQL secure installation:
sudo mysql_secure_installation
Follow the prompts and answer the questions to secure your MySQL server.
Step 7: Installing PHP
PHP is a popular scripting language for web development. Run the following command to install PHP and its extensions:
sudo apt-get install php libapache2-mod-php php-mysql
Restart Apache for the changes to take effect:
sudo systemctl restart apache2
