Complete Guide to Setting Up a Free VPN Server (VLESS, VMess, Trojan, SSH, SlowDNS)

Setting up a private VPN server is now much easier thanks to a multi-protocol auto-installer script. You can enable several modern protocols at once, including Xray (VLESS, VMess, Trojan), Shadowsocks, OpenVPN, SSH, and SlowDNS, complete with a terminal-based account management menu.

The script is free and open source, with no IP licensing restrictions, so it can be used on any VPS.

Prerequisites

Before you begin, make sure you have the following:

1. A VPS with root access
   You need a VPS with root access and a public IPv4 address.
2. A supported operating system
   • Ubuntu 20.04, 22.04, 24.04
   • Debian 10, 11, 12
3. A domain or subdomain
   A domain or subdomain pointed at your VPS IP via an A record. For example: vpn.yourdomain.com.
4. Cloudflare (optional)
   If you use Cloudflare for DNS management, make sure the proxy status is disabled (DNS Only or the grey cloud icon).

Installation Steps

1. Switch to the Root User

Log in to your VPS via terminal or SSH, then switch to root:

sudo -i

2. Run the Auto-Installer Script

Copy and run this command in your VPS terminal:

apt-get update && \
apt-get --reinstall --fix-missing install -y whois bzip2 gzip coreutils wget screen nscd build-essential && \
wget --inet4-only --no-check-certificate -O setup.sh https://raw.githubusercontent.com/alrescha79-cmd/sc-vpn/refs/heads/main/setup.sh && \
chmod +x setup.sh && \
screen -S setup ./setup.sh

The installation runs automatically. When prompted for a domain, type the domain or subdomain you pointed at your VPS IP.

Important Notes and Troubleshooting

• If the terminal connection drops during installation:
  Do not re-run the whole command from the start. Just log back in to the VPS and run:

  ./setup.sh

• Opening the control menu:
  After installation and the automatic reboot, the main menu appears on its own. If it does not, run:

  menu

• If the features menu (option 8) cannot be opened:
  Exit the menu with Ctrl + C, then download the updated features file:

  curl -o /usr/bin/features https://raw.githubusercontent.com/alrescha79-cmd/sc-vpn/refs/heads/main/project/features

Changing the Schedule via the Menu

1. In the main menu (menu), select option 8 (System Settings).

2. Select number 12 to enter the auto reboot settings.

4. Type y to save.

Setting or Cancelling via Crontab Directly

To set the schedule from the command line:

# Reboot every day at 05:00
crontab -l > /tmp/cron.txt
sed -i "/reboot$/d" /tmp/cron.txt
echo -e "\n"'0 5 * * * '"$(which reboot)" >> /tmp/cron.txt
crontab /tmp/cron.txt
rm -rf /tmp/cron.txt

To disable auto reboot:

crontab -l > /tmp/cron.txt
sed -i "/reboot$/d" /tmp/cron.txt
crontab /tmp/cron.txt
