The Apache HTTP Server, commonly referred to as Apache, is one of the world’s most popular open-source web servers. Its primary purpose is to serve web content to clients, such as web browsers when they request web pages or other resources over the internet. Apache is known for its stability, reliability, and flexibility. That’s why it is the best pick for hosting websites and web applications on Linux systems, including Ubuntu.

How to Configure Apache Web Server on Ubuntu 22.04?
Apache, like any web hosting server, must deal with the incoming and outgoing traffic. Thus, it is mandatory to allow operations of Apache through your Firewall. Moreover, Apache is managed by the backend service on Ubuntu 22.04. Therefore, the service must also be configured properly for smooth operations of Apache 2 on your Ubuntu 22.04. Let’s do all these configurations step by step, as follows:
Configure the Firewall
Use the UFW utility to allow Apache on Firewall, which can be done using the command:
| $ sudo ufw allow ‘apache full’ |
|---|
Reload the Firewall to make the changes effective:
| $ sudo ufw reload |
|---|
Lastly, it is recommended to check the status of the active services through Firewall:
| $ sudo ufw status |
|---|
Note: If you cannot make changes using UFW, the utility might be disabled. In such a scenario, you need to enable it via the command:
| $ sudo ufw enable |
|---|
Manage the Backend Apache Services
Now, it is time to configure the backend Apache services. The users can use the systemctl utility, and the following commands can be used:
Start the Apache Service
Initially, the Apache service might not be working. To make it functional, start the service using the command:
| $ sudo systemctl start apache2 |
|---|
Enable the Service
Enabling the Apache service will keep the service in the active state even after the reboot:
| $ sudo systemctl enable apache2 |
|---|
Check the Status
While dealing with the Apache service, the users must keep on tracing the status of the service, which can be done using the command:
| $ sudo systemctl status apache2 |
|---|
Stop the Service
If the service needs to be stopped, the following stop option of the systemctl command can be used:
| $ sudo systemctl stop apache2 |
|---|
Disable the Service
Sometimes, you might need to disable the Apache service. The service can be disabled via the command:
| $ sudo systemctl disable apache2 |
|---|
That’s how you can configure the Firewall and Apache backend service.

How to Remove Apache From Ubuntu 22.04?
Apache Web Server is not the package to be removed without any reason. If you are in need to remove it from Ubuntu 22.04, you can do it using the command:

|---|
