Sure, here is a tutorial for installing Redbird on OpenBSD:

Installing Redbird on OpenBSD

Redbird is a reverse proxy server that makes it easy to manage multiple HTTP(S) endpoints and websockets services behind a single IP address. In this tutorial, we will walk you through the steps to install Redbird on OpenBSD.

Step 1: Install Node.js

Redbird requires Node.js to be installed on the system. To install Node.js on OpenBSD, run the following command:

$ doas pkg_add node

This will install the latest stable version of Node.js on your system.

Step 2: Download and Extract Redbird

Download the latest version of Redbird from its GitHub repository:

$ doas pkg_add git
$ git clone https://github.com/OptimalBits/redbird.git

This will clone the Redbird repository into a directory called redbird.

Next, move into the redbird directory and extract the contents of the .tar.gz file:

$ cd redbird
$ tar -zxf redbird-<VERSION>.tar.gz

Replace <VERSION> with the current version of Redbird that you downloaded.

Step 3: Install Dependencies

Navigate to the extracted Redbird directory and install the required dependencies using npm:

$ cd redbird-<VERSION>
$ npm install

Step 4: Configure Redbird

Create a configuration file called config.js in the redbird-<VERSION> directory:

$ touch config.js

Open the configuration file in your preferred text editor and configure the endpoints that you want to proxy. For example:

module.exports = {
    port: 80,
    ssl: {
        port: 443,
        key: "/path/to/ssl/key",
        cert: "/path/to/ssl/cert"
    },
    letsencrypt: {
        path: __dirname + '/certs',
        port: 9999
    },
    bunyan: {
        name: 'redbird',
        level: 'debug'
    },
    sslRedirect: true,
    // add your endpoints here
    // example: 
    // mail.example.com -> http://localhost:3000
    // api.example.com -> http://localhost:4000
    portHttp: false // set http port to false by default
};

This example configuration will proxy requests to mail.example.com and api.example.com to http://localhost:3000 and http://localhost:4000, respectively.

Step 5: Start Redbird

To start Redbird, navigate to the redbird-<VERSION> directory and run the following command:

$ npm start

This will start Redbird and listen for incoming requests on the configured endpoints.

Congratulations! You have successfully installed Redbird on OpenBSD.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
