How to Install Outline Server on Alpine Linux Latest

Introduction

Outline Server is a free and open-source tool that allows you to create your own VPN server on your infrastructure. In this tutorial, we will guide you on how to install Outline Server on Alpine Linux Latest.

Prerequisites

Before you start with the installation, please make sure you have the following:

• An Alpine Linux Latest server
• Root or sudo user access to the server
• A stable and reliable internet connection

Step 1: Update the Package Repository

To make sure your system is up to date with the latest packages, first, we need to update the package repository. Run the following command:

sudo apk update

Step 2: Install Docker and Docker-Compose

Outline Server runs on Docker. Therefore, we need to install Docker Engine and Docker Compose on our server:

sudo apk add docker docker-compose

Step 3: Clone Outline-Manager and Outline-Server

Clone Outline-Manager and Outline-Server from GitHub with the following command:

git clone https://github.com/Jigsaw-Code/outline-server.git && cd outline-server && git checkout tags/v1.8.0

Step 4: Edit KeyPair

To encrypt the Outline server traffic running on the internet, Outline requires a public/private keypair. You can get the key through Let's Encrypt or generate your own self-signed certificate. We will show you how to create it using OpenSSL.

sudo -s
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout key.pem -out cert.pem
chmod 400 key.pem
sudo openssl dhparam -out ./certs/dhparam.pem 2048

Step 5: Creating a Server Configuration

To configure the Outline server, run the following command:

sudo -s
touch server.yml

Edit the file with your favourite text editor:

nano server.yml

Paste the following lines:

accessKeyId: <your-access-key-id>
defaultRoute: disable
apiListenAddress: "0.0.0.0:9090"
certSha256: <your-cert-sha-256>
dns:
  - "8.8.8.8"
  - "8.8.4.4"
managementApiAuthTokens:
  - <your-management-api-auth-token>

You need to replace the fields enclosed within '<>' symbols with your custom values. Additionally, add these fields as needed:

accessKeyId: An ID for accessing the server. You can create one by running the following command:

openssl rand -base64 18

certSha256: The SHA-256 fingerprint of your SSL certificate.

Note: Save the file by pressing Ctrl+X, Y and Enter.

Step 6: Start the Server

Start the Outline Server by running the following command:

cd ~ && nohup bash -c './outline-server --config=server.yml' > outline_server.log &

Conclusion

Congratulations! You have successfully installed Outline Server on Alpine Linux Latest. Now you can easily create your VPN server on your infrastructure.
