SunLicense VPS Setup Guide (Without Pterodactyl)
This guide will walk you through setting up SunLicense on a VPS without using Pterodactyl.
Prerequisites
Before starting, ensure your VPS meets the following requirements:
Java 21+ installed
A valid SunLicense license key
Installation Steps
1. Upload Required Files
Transfer the following files to your VPS:
server.jar
(SunLicense server file)license.txt
(Contains your license key)
You can use scp
or an FTP client like FileZilla to upload these files to your VPS.
Example using scp
:
scp server.jar license.txt user@your-vps-ip:/home/user/
2. Start SunLicense Server
Navigate to the directory containing server.jar
and license.txt
, then execute the following command:
SERVER_PORT=25595 java -Dterminal.jline=false -Dterminal.ansi=true -jar server.jar
Replace
25595
with the desired port number.Ensure the port is open in your firewall settings.
If Java 21+ is not installed, you can install it using:
sudo apt update
sudo apt install openjdk-21-jdk -y
3. Verify Local Access
Once the server starts, you can access SunLicense from the VPS itself:
curl http://localhost:25595
Replace 25595
with your chosen port.
4. Expose to the Internet (Optional)
If you want to access SunLicense from an external network, you need to configure a reverse proxy using Nginx.
Install Nginx
sudo apt install nginx -y
Configure Nginx Proxy
Create a new Nginx configuration file:
sudo nano /etc/nginx/sites-available/sunlicense
Add the following content:
server {
listen 80;
server_name yourdomain.com;
location / {
proxy_pass http://localhost:25595;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
Save and exit (CTRL + X
, then Y
, then Enter
).
Enable the Configuration
sudo ln -s /etc/nginx/sites-available/sunlicense /etc/nginx/sites-enabled/
Restart Nginx:
sudo systemctl restart nginx
Now, you can access SunLicense from http://yourdomain.com
.
5. Running on Port 80 (Alternative)
If you don't want to use Nginx, you can run SunLicense directly on port 80:
SERVER_PORT=80 java -Dterminal.jline=false -Dterminal.ansi=true -jar server.jar
Note: This works only if no other services (like Nginx or Apache) are using port 80.
6. Configure Firewall (If Required)
To allow external access, open the required ports:
sudo ufw allow 80/tcp
sudo ufw allow 25595/tcp
sudo ufw reload
7. Keeping SunLicense Running
To keep SunLicense running even after closing the terminal, use screen
or tmux
:
Using screen
sudo apt install screen -y
screen -S sunlicense
SERVER_PORT=25595 java -Dterminal.jline=false -Dterminal.ansi=true -jar server.jar
Press CTRL + A
, then D
to detach. To resume, use:
screen -r sunlicense
Using tmux
sudo apt install tmux -y
tmux new -s sunlicense
SERVER_PORT=25595 java -Dterminal.jline=false -Dterminal.ansi=true -jar server.jar
Detach with CTRL + B
, then D
. Resume with:
tmux attach -t sunlicense
Conclusion
SunLicense is now set up on your VPS without Pterodactyl. You can manage it manually or configure a systemd service for automatic startup. If you need a managed setup, consider SunLicense Managed Hosting.
