How To Install Apache on Ubuntu 20.04

What is Apache HTTP?

The Apache HTTP Server is a free and open-source cross-platform web server software, released under the terms of Apache License 2.0. Apache is developed and maintained by an open community of developers under the auspices of the Apache Software Foundation. 

Step 1 – Updating the system

sudo apt update

Step 2 – Install Apache

sudo apt install apache2

Step 3 – Check Apache status

sudo systemctl status apache2

Open your IP address on the browser to check if the Apache server is loading

Step 4 – Set up Virtual Hosts

Create your domain directory on the server

sudo mkdir /var/www/domain-name

---

Give permissions to your domain directory

sudo chmod -R 755 /var/www/domain-name

---

Create a sample index.html

touch /var/www/domain-name/index.html
echo "Your domain is now online" > /var/www/domain-name/index.html

---

Create a virtual host file

sudo nano /etc/apache2/sites-available/domain-name.conf

---

Add the following content to your domain-name.conf file

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    ServerName domain-name
    ServerAlias www.domain-name
    DocumentRoot /var/www/domain-name
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

---

Use a2ensite to enable the file

sudo a2ensite domain-name.conf 
or 
sudo a2ensite /etc/apache2/sites-available/domain-name.conf

---

Next, we have to disable the default file

sudo a2dissite 000-default.conf

---

Check for errors

sudo apache2ctl configtest

The output should be Syntax OK

---

Restart Apache and navigate to your domain on the browser

sudo systemctl restart apache2
