Have you ever imagined running a web server directly from your Android phone? With the UserLAnd app, not only is it possible, but it’s also easy! This article will guide you step-by-step on how to set up an Nginx web server on your Android device. It’s a great solution for developers or server admins on the go who want to stay productive. Let’s get started!
What Is Nginx and UserLAnd?
Nginx is a popular web server used for serving websites or web applications. Besides being a web server, Nginx can also function as a reverse proxy, load balancer, and media streaming server.
On the other hand, UserLAnd is an app that allows you to run Linux distributions on Android without rooting your device. With this app, you can install various Linux apps, including Nginx, directly on your Android phone.
Prerequisites
Before starting, ensure you have:
- Android smartphone (Android 5.0 or higher)
- Userland app (free on Play Store)
- At least 1GB free storage
- Stable internet connection
- Battery level above 50%
Installation Steps
1. Installing Userland
- Open Play Store
- Search and install “UserLAnd“
- Wait for installation to complete
- Launch the app
2. Initial Userland Setup
- Select “Ubuntu” as the operating system
- Create username and password
- Wait for download and installation to complete
3. install neofetch and nano
- Install nano to text editor
sudo apt install nano -y
- install neofetch to view linux information
sudo apt install neofetch
4. Installing NGINX
After accessing the Ubuntu terminal, run these commands:
sudo apt update
sudo apt upgrade -y
sudo apt install nginx -y
NGINX Configuration
1. Basic Setup
sudo nano /etc/nginx/sites-available/default
Change server default 80 to 8080
# Default server configuration
#
server {
listen 8080 default_server;
listen [::]:8080 default_server;
# SSL configuration
#
# listen 443 ssl default_server;
# listen [::]:443 ssl default_server;
Then restart nginx
sudo service nginx restart
To check the IP address on an Android device, you can use several methods to find both your local IP (Wi-Fi or mobile network) and public IP. Here are a few ways to do it:
2. Viewing Local IP Address via Android Settings
This method shows the IP address assigned by your local network (Wi-Fi or mobile data):
- Open Settings on your Android device.
- Select “Wi-Fi” if you’re connected via Wi-Fi, or “Network & Internet” for mobile data.
- Tap on the Wi-Fi network you’re connected to.
- Scroll down, and you will see the IP Address under the network details.
For mobile networks, you can check Settings > About Phone > Status, and the IP Address will be listed there.
For example, the ip address on my phone is 192.168.1.5
Running the Web Server
1. Starting NGINX
sudo service nginx start
2. Checking Status
sudo service nginx status
3. Accessing the Web Server
- Open a browser on another device
- Type:
http://[ANDROID_IP_ADDRESS]:8080
- At this stage nginx has succeeded
192.168.1.5 is my ip address, each device is different.
Creating Web Page
cd /var/www/html
sudo rm -r index.nginx-debian.html
sudo nano index.html
