Before we dive into the tutorial, let’s first discuss what Apache is and why you should consider using it as your web server.
What is Apache?
Apache is free and open-source software that runs on various operating systems, including Ubuntu. It’s a robust, reliable, and scalable web server that supports multiple protocols and technologies, including HTTP, SSL, and CGI. Apache is designed to handle high-traffic websites and can be used to serve static and dynamic content.
Why Use Apache?
There are several reasons why you should consider using Apache as your web server. Here are some of them:
- Apache is free and open-source software, which means you don’t have to pay for it.
- It’s a cross-platform web server that can run on multiple operating systems.
- Apache is highly customizable and can be configured to suit your specific needs.
- It’s a reliable and stable web server that has been around for over two decades.
- Apache has a large and active community of developers and users who provide support and contribute to its development.
Now that we’ve covered the basics of Apache let’s move on to the tutorial.
Setting Up Apache on Ubuntu
Step 1: Updating Ubuntu
Before we start installing Apache, we need to update the Ubuntu operating system to ensure that we have the latest packages and security updates. Open your terminal and enter the following command:
Command |
Description |
|---|---|
sudo apt update |
Updates the package index and fetches the latest package versions. |
sudo apt upgrade |
Upgrades the installed packages to their latest version. |
After executing these commands, your Ubuntu operating system will be up-to-date with the latest security patches and software updates.
Step 2: Installing Apache
The next step is to install Apache on Ubuntu. To do that, enter the following command in your terminal:
Command |
Description |
|---|---|
sudo apt install apache2 |
Installs the Apache2 web server on Ubuntu. |
The Apache2 package will be downloaded and installed on your Ubuntu operating system. After the installation is complete, Apache will be automatically started and will run as a background service.
Step 3: Configuring Apache
Apache is now installed on your Ubuntu system, but we need to configure it before we can use it as our web server. The Apache configuration files are located in the /etc/apache2 directory. The main configuration file is apache2.conf.
Before we start making changes to the configuration file, let’s first back it up in case something goes wrong. Type the following command in your terminal:
Command |
Description |
|---|---|
sudo cp /etc/apache2/apache2.conf /etc/apache2/apache2.conf.bak |
Copies the apache2.conf file to a backup file. |
Now that we have a backup of the configuration file let’s make some changes to it to make Apache work for our needs. There are several configuration files you can change, but for this tutorial, we’ll only cover a few of them.
Step 4: Testing Apache
Now that we have Apache installed and configured let’s test it to make sure it’s working correctly. Open your web browser and enter the IP address of your Ubuntu server in the address bar. If everything is working correctly, you should see the Apache default welcome page.
