How to Install and Configure Apache on Ubuntu 18.04 LTS

How to Install and Configure Apache on Ubuntu 18.04 LTS

This tutorial will help you to install and secure Apache web server on Ubuntu 18.04 LTS Linux operating system.


  • SSH access to Ubuntu 18.04
  • SUDO privilege

Install Apache on Ubuntu 18.04

First of all, Login to your Ubuntu 18.04 system via SSH and update the Apt cache. Then install Apache2 HTTP server packages as following:

sudo apt update
sudo apt install apache2

To install most latest version of Apache use the following PPA.

sudo add-apt-repository ppa:ondrej/apache2
sudo apt update
sudo apt install apache2

Manage Apache Service

Apache service is managed with systemctl command line. After installation, use the following command to check the status of Apache service.

sudo systemctl status apache2.service

Apache Service Status Ubuntu

Here is the other commands to stop, start or restart Apache service via command line.

sudo systemctl stop apache2.service
sudo systemctl start apache2.service
sudo systemctl restart apache2.service

Test Apache Setup

Use the following command to view the installed Apache version on your Ubuntu 18.04 Linux system.

apache2 -v

Server version: Apache/2.4.41 (Ubuntu)
Server built:   2019-10-15T19:53:42

Now access your Apache server using the server’s IP address or a domain pointed to the server IP. You will see a default Apache page on web browser. It means Apache web server has successfully installed on your Ubuntu 18.04 system.

Install Apache2 on Ubuntu 18.04

Create New VirtualHost

Let’s create the first virtual host on your Apache server. For the tutorial, we are using sample domain “”. Here we will create a Virtual host for on port 80.

Create a directory and create a sample index file in a directory:

sudo mkdir -p /var/www/
sudo echo "Welcome" > /var/www/

Then create Virtualhost configuration file and edit in editor:

sudo vim /etc/apache2/sites-available/

Add the following content in configuration file. You may change the domain name as per your domain.

    DocumentRoot /var/www/
           #Allowoverride all    ###Uncomment if required

    ErrorLog ${APACHE_LOG_DIR}/example.com_error.log
    CustomLog ${APACHE_LOG_DIR}/example.com_access.log combined

Save the Virtualhost configuration file, then enable Virtualhost and reload the Apache service using the following commands:

sudo a2ensite
sudo systemctl reload apache2.service

Configure SSL VirtualHost

You can skip this step if you don’t need SSL. But the security is always the primary concert for any website.

The default Apache https listen on port 443. Make sure no other services using the same port. Now, you need to enable Apache ssl module, which is disabled by default.

sudo a2enmod ssl

For the tutorial, I have followed these instructions to generate a self signed SSL certificate for our domain.

Then create a new Virtual host file and edit it:

sudo vim /etc/apache2/sites-available/example.com_ssl.conf

with the following content:

    DocumentRoot /var/www/
           #Allowoverride all    ###Uncomment if required

    SSLEngine on
    SSLCertificateFile /etc/pki/tls/certs/
    SSLCertificateKeyFile /etc/pki/tls/certs/
    ErrorLog ${APACHE_LOG_DIR}/example.com_ssl-error.log
    CustomLog ${APACHE_LOG_DIR}/example.com_ssl-access.log combined

Here is three terms used to configure SSL virtualhost:

  • SSLEngine – Set this to “on”
  • SSLCertificateFile – Set the path of your SSL certificate
  • SSLCertificateKeyFile – This is the private key files used to generate SSL certificate

After that enable the Virtualhost and reload the Apache service using the following commands:

sudo a2ensite example.com_ssl
sudo systemctl reload apache2.service

Secure Apache Server

Edit the Apache security configuration file

sudo vim /etc/apache2/conf-enabled/security.conf

Here is the multiple security related settings. Add or Update the following settings. We are not going in detailed discriptions about it but these settings are very useful for the production servers.

ServerTokens Prod
ServerSignature Off
TraceEnable Off
Header always append X-Frame-Options SAMEORIGIN
Header always set X-XSS-Protection: "1; mode=block"
Header always set X-Content-Type-Options: "nosniff"
Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains"
Header always edit Set-Cookie ^(.*)$ $1;HttpOnly;Secure

Now edit SSL configuration file. Here you can set the server wide SSL protocol and SSLCipherSuite to use secure Cipers to serve your website.

sudo vim /etc/apache2/mods-enabled/ssl.conf
SSLProtocol -all +TLSv1.2
SSLCipherSuite HIGH:!aNULL:!MD5

After making changes restart the Apache service to apply new configuration.

sudo systemctl reload apache2.service


All done, You have installed and secured Apache server on your Ubuntu 18.04 Bionic Linux system.
