Apache is popular and most widely used cross-platform HTTP server. It powers a large number of websites and includes many powerful features, dynamically loadable modules with other popular software. This tutorial explains how to install Apache web server on Ubuntu 20.04 Focal Fossa.
Install Apache on Ubuntu
Before you begin installation, make sure you are logged in as root or a non-root user account with sudo privileges.
Step 1 – Installing Apache
By default, Apache package is available in within Ubuntu repositories. Let’s update the package index first and then install
sudo apt update
sudo apt install apache2
Here, we use sudo as command so these operations are executed with root privileges and it will prompt you to enter your regular user
password to verify.
Once Apache is installed and it will start
apache2 service automatically.
Step 2 – Adjusting the Firewall
After Apache installation make sure that your firewall allows HTTP and HTTPS traffic. You can get list of
ufw profile list by typing :
sudo ufw app list
Available applications: Apache Apache Full Apache Secure OpenSSH
Allow incoming HTTP and HTTPS traffic for this profile:
sudo ufw allow in "Apache Full"
Step 3 – Verifying Apache Installation
At this point, your Apache web server should be up and running. To verify that Apache works correctly, execute below command :
sudo systemctl status apache2
It will show you output like below :
● apache2.service - The Apache HTTP Server Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled) Active: active (running) since Thu 2020-05-03 10:15:30 UTC; 10s ago Docs: https://httpd.apache.org/docs/2.4/ ...
Alternatively, open your web browser, type your server IP address or domain name
http://YOUR_SERVER_IP and you will see the default Apache welcome page as shown below:
This page means that Apache is working correctly. It also showing some basic information about important Apache files and directory locations.
Step 4 – Manage Apache Processes
Now your web server is installed and up to run so we will see some basic management commands.
To stop Apache service you can run :
sudo systemctl stop apache2
You can again start Apache service by type :
sudo systemctl start apache2
To do Restart (stop and start) the Apache service:
sudo systemctl restart apache2
If you have need to making configuration changes, Apache can reload without dropping connections. For this, use this command:
sudo systemctl reload apache2
If you want to disable the Apache service type:
sudo systemctl disable apache2
To re-enable the service to start up at boot, type:
sudo systemctl enable apache2
Apache service should start automatically when the server boots again.
