Ubuntu rocks!

Install and Configure Apache Web Server on Ubuntu 20.04

Apache web server is the most extensively used open-source web server supported on the majority of the OS including Linux, Windows, MacOS, Solaris, etc. It is highly customizable and can be integrated with other modules. Installing and configuring Apache for basic setup is quite easy. This article will explain how to install and configure the Apache web server on Ubuntu operating system.

Note: We have explained the procedure explained in this article on a Ubuntu 20.04 LTS system.

Installing Apache2; Step 1: Update

First, we will need to update the system repository index to install the most recent version of Apache2. To do so, launch the Terminal by using the Ctrl+Alt+T shortcut and execute the following command:

Note that, only an authorized user can install, update, or remove the packages from the Linux system.

Step 2: Install Apache2

Next in this step, we will install Apache2 web server. For this, execute the below command in Terminal:

The system might ask for confirmation by providing you with a Y/n option. Hit y and then Enter to continue. After that, the Apache2 web server and its all dependencies will be installed on your system.

Once installed, verify the version of the Apache server as follows:

Firewall configuration

Now, we will need to open certain ports on our system in order to access Apache from outside. First, let’s list the application profiles that we need to give Apache access to. Run the following command to do so:

Here you can see different apache profiles.

We will use the highly restrictive profile ‘Apache’ to enable network ctivity on port 80.

Now check the status which will show Apache allowed in firewall.

Configuring Apache web server; Verifying Apache service

Before moving towards configuration, first, verify if the Apache service is operational. For this, execute the below command in Terminal:

From the above output, you can see the Apache2 service is active and running.

Another approach to verify if Apache is running fine by requesting a web page from the Apache web server. To do so, find your IP address using the following command:

Then open the web browser and access apache welcome page as follows:

Replace the 192.168.72.134 by the IP address of your machine.

By navigating to the above link in the browser, you see the Apache welcome page which is the indication that the Apache server is working properly.

Setting Up Virtual Hosts in Apache

If you have multiple domains that need to be server from the single Apache web server, then you will require to set up virtual hosts. In the following, we will show you how to set up a virtual host in Apache. We will set up the domain name “info.net”. Make sure to replace the info.ne with your own domain name.

Step 1: Create a directory for your domain

In this step, we will create a directory for our domain name. This directory will be used for storing the data on our website.

Run the following command in Terminal by replacing the info.net with your own domain name:

Change the directory ownership to current user:

Assign necessary permissions as follows:

Step 2: Make a sample page for your website

We have setup virtual host and assign necessary permission. Now we, will create a sample page for our website. We will create the sample page using Nano editor, however, any text editor can be used for this purpose.

Copy paste these lines of HML code:

Now use Ctrl+O to save and then Ctrl+X to exit the file.

Step 3: Create a virtual host file

Apache server comes with virtual host file by default. This file is used to serve the contents of the web server. However, we will generate the new virtual host file with the following command:

Now enter the below lines by replacing the info.net by your own domain name.

< VirtualHost * : 80 >
ServerAdmin admin @ info.net
ServerName info.net
ServerAlias info.net
DocumentRoot / var / www / info.net / html
ErrorLog $ / error.log
CustomLog $ / access.log combined

Now use Ctrl+O to save and then Ctrl+X to exit the file.

Step 4: Activate virtual host configuration file

In this step, we will be creating the virtual host configuration file. For this, execute the following command in Terminal:

Now disable the “000-default.conf” default virtual configuration file as follows:

Now restart Apache to activate the new configuration as follows:

Step 5: Test for errors

Once all the configurations are completed, you can test for any configuration errors:

You might receive the following error:

In order to resolve this error, edit the servername.conf file:

Then add this line by replacing the info.net with your own domain name:

Save and exit the servername.conf file and run:

This time, hopefully, you will not receive any error.

Step 6: Test virtual host

Now the Apache web server is ready to serve our domain. Let’s test this by navigating to the following link in the browser:

Replace the info.net with your domain name.

The following index page shows the Apache server is ready to serve our domain name.

Managing Apache server

In order to manage the Apache server, here are some of the useful commands that you can run in Terminal:

To start the Apache server:

To stop the Apache server:

To stop and then start Apache”

To reload apache server to update the new configurations:

To disable Apache at boot:

This article has explained in detail the installation and configuration of Apache web server in Ubuntu 20.04. We have also explained setting up a virtual host. Now you can set up multiple domains in the same Apache server. In the end, we have mentioned some commands that can be very helpful in managing the Apache web server.

Install and Configure Apache

Apache is an open source web server that’s available for Linux servers free of charge.

In this tutorial we’ll be going through the steps of setting up an Apache server.

What you’ll learn

What you’ll need

  • Ubuntu Server 16.04 LTS
  • Secure Shell (SSH) access to your server
  • Basic Linux command line knowledge

Got everything ready? Let’s move on to the next step!

2. Installing Apache

To install Apache, install the latest meta-package apache2 by running:

sudo apt update sudo apt install apache2 

After letting the command run, all required packages are installed and we can test it out by typing in our IP address for the web server.

Apache-Installed

If you see the page above, it means that Apache has been successfully installed on your server! Let’s move on.

3. Creating Your Own Website

By default, Apache comes with a basic site (the one that we saw in the previous step) enabled. We can modify its content in /var/www/html or settings by editing its Virtual Host file found in /etc/apache2/sites-enabled/000-default.conf .

We can modify how Apache handles incoming requests and have multiple sites running on the same server by editing its Virtual Hosts file.

Today, we’re going to leave the default Apache virtual host configuration pointing to www.example.com and set up our own at gci.example.com .

So let’s start by creating a folder for our new website in /var/www/ by running

We have it named gci here but any name will work, as long as we point to it in the virtual hosts configuration file later.

Now that we have a directory created for our site, lets have an HTML file in it. Let’s go into our newly created directory and create one by typing:

cd /var/www/gci/ nano index.html 

Paste the following code in the index.html file:

      

I'm running this website on an Ubuntu Server server!

Now let’s create a VirtualHost file so it’ll show up when we type in gci.example.com .

4. Setting up the VirtualHost Configuration File

We start this step by going into the configuration files directory:

cd /etc/apache2/sites-available/ 

Since Apache came with a default VirtualHost file, let’s use that as a base. ( gci.conf is used here to match our subdomain name):

sudo cp 000-default.conf gci.conf 

Now edit the configuration file:

We should have our email in ServerAdmin so users can reach you in case Apache experiences any error:

ServerAdmin yourname@example.com 

We also want the DocumentRoot directive to point to the directory our site files are hosted on:

The default file doesn’t come with a ServerName directive so we’ll have to add and define it by adding this line below the last directive:

This ensures people reach the right site instead of the default one when they type in gci.example.com .

Now that we’re done configuring our site, let’s save and activate it in the next step!

5. Activating VirtualHost file

After setting up our website, we need to activate the virtual hosts configuration file to enable it. We do that by running the following command in the configuration file directory:

You should see the following output

Enabling site gci. To activate the new configuration, you need to run: service apache2 reload root@ubuntu-server:/etc/apache2/sites-available# 

To load the new site, we restart Apache by typing:

End result

Final

Now is the moment of truth, let’s type our host name in a browser. Hooray!
