Apache is one of the most widely used HTTP web servers. It’s used for setting up Apache and security with an SSL certificate.
In this article, we will learn how to set up Apache for your website on Ubuntu and CentOS.
Creating DNS Record
Login to Cloudflare or your domain registrar (if not Cloudflare) and create an A record to point the domain to the cloud VMs IP.
Refer to the image given below:
Installing Apache (Ubuntu)
To update the available packages up-to-date:
sudo apt-get update
Install Apache
sudo apt-get install apache2
Allow ports 80 and 443 in your firewall for the HTTP server.
Type the command given below:
sudo ufw allow ‘Apache Full’
Check out that your installed Apache runs perfectly.
sudo systemctl status apache2
Configuring Apache to Serve the Important Files
Follow the steps given below to do so:
Create a folder for serving your web apps
sudo mkdir -p /var/www/test.sanakil.xyz/webapp
sudo vi /var/www/test.sanakil.xyz/webapp/index.html
Now paste the below HTML snippet for testing.
<!DOCTYPE html> <html lang=”en”> <head> <title>Apache webapp</title> </head> <body> <h1>My Apache webapp is working in test.sanakil.xyz</h1> </body> </html>
Then, you need to create a folder for generating and storing the logs.
Type the command given below:
sudo mkdir -p /var/www/test.sanakil.xyz/log sudo touch
/var/www/test.sanakil.xyz/request.log sudo touch
/var/www/test.sanakil.xyz/log/error.log
Open Conf file (Ubuntu)
To do so:
sudo vi /etc/apache2/sites-available/test.sanakil.xyz.conf
Open conf file (CentOS)
sudo vi /etc/httpd/sites-available/test.sankil.xyz.conf
Paste the below conf snippet by making a change in your domain name.
<VirtualHost *:80>
ServerName test.sanakil.xyz
ServerAlias test.sanaki.xyz
DocumentRoot /var/www/test.sanakil.xyz/webapp
ErrorLog /var/www/test.sankil.xyz/log/error.log
CustomLog /var/www/test.sanakil.xyz/log/requests.log combined
</VirtualHost>
You will have to give the required permission for your folder.
sudo chown -R $USER:$USER /var/www/test.abc.xyz
Copy
sudo chmod -R 755 /var/www/test.abc.xyz
Enable your virtual host config file in apache(Ubuntu)
sudo a2ensite test.sanakil.xyz.conf
First, disable the default conf file for security reasons.
sudo a2dissite 000-default.conf
Restart the Apache to make changes to take effect.
sudo systemctl restart apache2
Additional Setup for CentOS
In CentOS(SELinux), everything is not enabled by default like Ubuntu.
Create sites-enabled and sites-available folders in Apache.
sites-enabled – serves visitors with the cof files in it
sites-available – stores the virtual host conf files
sudo mkdir /etc/httpd/sites-available /etc/httpd/sites-enabled
Tell the apache to read the conf file in the sites-enabled folder.
sudo vi /etc/httpd/conf/httpd.conf
Then, add the below line at end of the file
IncludeOptional sites-enabled/*.conf
Steps to Enable HTTPS
Enabling HTTPS in the Apache web server in Ubuntu is easy with the certbot and Let’s Encrypt.
Let’s Encrypt is a Certificate Authority that provides free SSL certificates for millions of websites.
On the other hand, Certbot is software that automatically sets up HTTPS for our website using Let’s Encrypt.
Adding and Install Certbot for Apache (Ubuntu)
Enter the commands given below:
sudo add-apt-repository ppa:certbot/certbot
sudo apt install python-certbot-apache
Adding and Installing certbot for Apache (CentOS)
sudo yum install epel-release
sudo yum install certbot python2-certbot-apache mod_ssl
Getting an SSL Certificate
sudo certbot –apache -d your-domain-name
This is how the verification is done by certbot with no issues. You will be asked for HTTPS redirection.
Choose option two and click on enter. That’s it!
Hope this article has given you an idea of how to install and execute an SSL certificate on Apache.
