Ubuntu 18.04 Apache Server Setup: Step-by-Step Guide
Step 1: Update Ubuntu
The first step is to ensure that your Ubuntu operating system is up-to-date. This is important because it will ensure that you have the latest security updates and bug fixes. Open the terminal and run the following command:
Command |
Description |
|---|---|
sudo apt-get update |
Updates the package list to the latest version |
sudo apt-get upgrade |
Upgrades the installed packages to the latest version |
This may take a few minutes, depending on the size of the updates and the speed of your internet connection.
Step 2: Install Apache Web Server
Once your Ubuntu system is updated, you can install the Apache web server using the following command:
Command |
Description |
|---|---|
sudo apt-get install apache2 |
Installs the Apache web server and all its required dependencies |
After the installation is complete, you can check whether Apache is running by entering your server’s IP address in a web browser:
Command |
Description |
|---|---|
http://server-ip-address |
Accesses the Apache web server on your Ubuntu server |
If Apache is running correctly, you should see the default Apache2 Ubuntu Default Page. Congratulations, you now have a functional Apache web server!
Step 3: Configure Firewall to Allow Web Traffic
By default, Ubuntu comes with a firewall called UFW (Uncomplicated Firewall) enabled. This firewall blocks all incoming connections to your server except for SSH, which is used for remote access. To allow web traffic on your server, you need to open port 80 (HTTP) and port 443 (HTTPS) on the firewall using the following commands:
Command |
Description |
|---|---|
sudo ufw allow 80/tcp |
Opens port 80 for incoming HTTP traffic |
sudo ufw allow 443/tcp |
Opens port 443 for incoming HTTPS traffic |
sudo ufw enable |
Enables the UFW firewall |
Now, your Ubuntu server can receive incoming web traffic.
Step 4: Create a Virtual Host for Your Web Application
Apache uses a virtual host to bind a web server to a specific domain name or IP address. To create a virtual host, you need to create a new configuration file in the /etc/apache2/sites-available directory using the following command:
Command |
Description |
|---|---|
sudo nano /etc/apache2/sites-available/myapp.conf |
Opens a new configuration file for the virtual host using the nano text editor |
In this file, you can define the configuration for your web application. Here’s a sample configuration:
Step 5: Enable the Virtual Host and Restart Apache
After creating the virtual host, you need to enable it using the following command:
Command |
Description |
|---|---|
sudo a2ensite myapp.conf |
Enables the virtual host configuration |
Finally, you need to restart the Apache web server using the following command:
Command |
Description |
|---|---|
sudo systemctl restart apache2 |
Restarts the Apache web server to apply the new configuration |
