How to Install Misskey on OpenBSD

Misskey is a social networking platform that allows users to share their thoughts and ideas in a decentralized and open-source space. In this tutorial, we will guide you on how to install Misskey on OpenBSD.

Prerequisites

Before you start, you need to have the following:

• A server or VPS running OpenBSD
• SSH access to the server
• Basic knowledge of the command line

Step 1: Install Required Packages

First, we need to install some required packages for Misskey to run properly. Open the terminal on your OpenBSD server and run the following command:

doas pkg_add nginx nodejs mongodb

This command installs the Nginx web server to serve Misskey, Node.js for running the application, and MongoDB for the database.

Step 2: Set Up the Firewall

By default, OpenBSD comes with pf, a firewall that is easy to use and configure. We'll need to allow incoming traffic on port 80 (HTTP) and 443 (HTTPS). Run the following command:

echo "pass in proto tcp from any to any port { 80 443 }" | sudo tee /etc/pf.conf

This command creates a rule in pf.conf to allow incoming traffic on HTTP and HTTPS.

Reload the pf service to apply these new rules, using the following command:

doas pfctl -f /etc/pf.conf

Step 3: Download Misskey

Now, let's download the latest version of Misskey.

git clone https://github.com/syuilo/misskey.git && cd misskey

Step 4: Install Misskey Dependencies

Misskey requires several dependencies to be installed before running it. Run the following command within the misskey directory:

npm ci --production

This will install all the dependencies required by the Misskey application.

Step 5: Configure Misskey

Now, let's set up the configuration files for Misskey. First, make a new directory for the Misskey configuration files:

mkdir config
cd config

Next, create a new file called default.toml with the following contents:

[server]
port = 3000
bind = "127.0.0.1"

[mongodb]
uri = "mongodb://localhost/misskey"

[redis]
host = "127.0.0.1"
port = 6379

[web-push]
public-key = ''
private-key = ''

This file contains the server configuration options, as well as the configuration options for the MongoDB database and Redis cache.

Step 6: Start MongoDB and Redis

Before starting Misskey, we need to start the MongoDB database and Redis cache. Use the following commands:

sudo /etc/rc.d/mongod start
sudo /etc/rc.d/redis start

Step 7: Start Misskey

Finally, we can start Misskey by running the following command:

npm start

Misskey should now be running on localhost:3000. You can access the Misskey front-end by opening a web browser and navigating to your server's IP address.

Step 8: Set Up Nginx

To serve Misskey over HTTPS and to route the domain name to Misskey, we need to set up Nginx. Create a new file /etc/nginx/nginx.conf with the following contents:

http {
    server {
        listen 80 default_server;
        return 301 https://$host$request_uri;
    }
    server {
        listen 443 ssl http2;
        server_name your-domain.com;
        ssl_certificate /path/to/ssl/certificate;
        ssl_certificate_key /path/to/ssl/key;
        location / {
            proxy_pass http://127.0.0.1:3000;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
   	 }
    }
}

Replace your-domain.com with your domain name and /path/to/ssl/certificate and /path/to/ssl/key with the file paths to your SSL certificate and key.

Restart Nginx to apply the changes:

sudo /etc/rc.d/nginx restart

Conclusion
