Introduction
Greetings, esteemed readers! In today’s tech-driven world, web servers are vital tools for hosting websites, applications, and other online services. Apache server, a robust open-source web server, is widely used due to its flexibility, stability, and security features. In this article, we will provide a detailed guide on how to start the Apache server using Ubuntu commands. Our aim is to empower you to configure and manage your web server with ease. So, let’s get started!
Understanding Apache Server Ubuntu Command
Before we dive into the command-line interface, it’s crucial to understand some basic concepts about Apache server and Ubuntu. Apache is a powerful, cross-platform web server software designed to deliver web pages in response to HTTP requests. Ubuntu, on the other hand, is a Linux-based operating system widely used on servers and desktops. Using Ubuntu commands, you can install and configure Apache server to meet your specific needs. There are several ways to start Apache server in Ubuntu, but we will focus on using the command line interface.
Prerequisites
To start Apache server using Ubuntu command line, you need to have the following prerequisites:
Prerequisites |
Description |
|---|---|
Ubuntu Linux OS |
The latest version of Ubuntu installed on your machine |
Root Access |
You must have root access or sudo privileges to install and configure Apache server and related packages |
Apache Web Server Package |
You need to have the Apache web server package installed on your Ubuntu system. You can install it using the following command: sudo apt-get install apache2 |
Steps to Start Apache Server Ubuntu Command
Once you have met the prerequisites, you can follow the steps below to start Apache server using Ubuntu command line:
Step 1: Check Apache Server Status
Before starting the Apache server, you need to check its status to ensure that it is not already running. You can use the following command to check the status:
sudo systemctl status apache2
If Apache is not running, you will see the following output:
apache2.service - The Apache HTTP Server
Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled)
Active: inactive (dead)
If Apache is running, you will see a similar output, but with the “Active” line showing “active” instead of “inactive”:
apache2.service - The Apache HTTP Server
Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled)
Active: active (running)
Step 2: Start Apache Server
To start Apache server, use the following command:
sudo systemctl start apache2
This command will start the Apache server. If there are no errors, you will not see any output.
Step 3: Verify Apache Server Status
After starting Apache server, you should verify its status again to confirm that it has started successfully. Use the following command:
sudo systemctl status apache2
If the Apache server has started successfully, you will see the following output:
apache2.service - The Apache HTTP Server
Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled)
Active: active (running)
Congratulations! You have successfully started the Apache server using Ubuntu command line.
