You are looking at installing your own VPN? Don't look further! Pritunl comes with a bunch of features that will make you regret paying for private VPN.
Before installing Pritunl you will need a VPS. You can create a small droplet on Digital Ocean. If you have not created an account you may use the referral link to receive a $100 credit when creating an account. After logging in click Create Droplet then follow the tutorial to install Pritunl on your VPS.
Scaleway is a great alternative to Digital Ocean. If you manage to snatch a Stardust instance you'll be able to run your VPN for less than $2 a month. One of the advantages of Scaleway is that you don't pay for outgoing traffic. You are dependent on the outgoing network speed. If you want to increase the speed of the VPN you have to increase the size of the VPS.
Let's get started, I assume that you have an Ubuntu/Debian instance running and that you are connected to it.
- Ubuntu Focal 20.04 LTS
- Debian Buster
Add Pritunl Package
Pritunl isn't available right out of the box. You need to add the packages.
Depending on your operating system, either follow the instruction for Debian Buster or the Ubuntu Focals one.
sudo tee /etc/apt/sources.list.d/pritunl.list << EOF deb https://repo.pritunl.com/stable/apt buster main EOF sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com --recv 7568D9BB55FF9E5287D586017AE645C0CF8E292A
sudo tee /etc/apt/sources.list.d/pritunl.list << EOF deb http://repo.pritunl.com/stable/apt focal main EOF sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com --recv 7568D9BB55FF9E5287D586017AE645C0CF8E292A
Once you've installed
sudo apt-get update
You should now be able to install Pritunl. Before doing that we'll need to add MongoDB as Pritunl requires it.
Don't worry about performance. Even the smallest VPS on DigitalOcean and Scaleway can run both Pritunl and MongoDB
Add MongoDB Package
Import the public key
wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -
Create the list file
echo "deb http://repo.mongodb.org/apt/debian buster/mongodb-org/4.4 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list
sudo apt-get update
Install MongoDB and Pritunl Packages
Now that both packages have been added, you can install MongoDB and Pritunl by running the following commands
sudo apt-get install -y mongodb-org pritunl
Start the MongoDB and Pritunl Services
To start both Pritunl and MongoDB you'll need to start the services.
sudo systemctl start pritunl mongod
Increase Open File Limit
Run the commands below to increase the open file limit on the server. This will prevent connections issues on servers with high load. This should also be done on the MongoDB server. Use the command
sudo lsof -p pgrep pritunl-web | wc -l to check the file count for the Pritunl web server.
sudo sh -c 'echo "* hard nofile 64000" >> /etc/security/limits.conf' sudo sh -c 'echo "* soft nofile 64000" >> /etc/security/limits.conf' sudo sh -c 'echo "root hard nofile 64000" >> /etc/security/limits.conf' sudo sh -c 'echo "root soft nofile 64000" >> /etc/security/limits.conf'
At this point, Pritunl VPN is installed and running. Access it from the browser using your server IP to configure it. http://<your_server_ip>. You should get a page as below:
Generate setup-key by running the command below:
sudo pritunl setup-key
The default username and password are obtained with the below command:
sudo pritunl default-password ... [undefined][2021-01-29 20:10:17,550][INFO] Getting default administrator password Administrator default password: username: "pritunl" password: "xGupSTJtdiJ8"
I hope that you've successfully installed Pritunl. You should be able to connect to it either by using the Pritunl App or by using the OpenVPN Client app on Android, iOS, macOS, Windows, Linux, etc ...
