How to Install Fussel on OpenBSD

Fussel is a web-based photo management system. Here is a step-by-step guide on how to install it on OpenBSD.

Prerequisites

Before installing Fussel, make sure that your system meets the following prerequisites:

OpenBSD 6.0 or later
Root access or privileges to install packages and dependencies
Internet connectivity to download required packages

Steps

Follow the steps below to install Fussel on OpenBSD:

Update the package repository using the following command:
```
$ doas pkg_add -u
```
Install required packages using the following command:
```
$ doas pkg_add -I py3-pillow py3-pip py3-virtualenv nginx py3-gunicorn
```
This will install the required packages for running Fussel.
Create a virtual environment for Python using the following command:
```
$ doas mkdir /usr/local/fussel
$ doas chown $USER /usr/local/fussel
$ doas virtualenv --python python3 /usr/local/fussel/fussel_venv
```
This will create a virtual environment for Python in /usr/local/fussel/fussel_venv.
Activate the virtual environment using the following command:
```
$ . /usr/local/fussel/fussel_venv/bin/activate
```
This will activate the virtual environment and you will see (fussel_venv) in the shell prompt.
Use pip to install Fussel from GitHub using the following command:
```
$ pip install git+https://github.com/cbenning/fussel.git
```
This will download and install Fussel from the GitHub repository.

Configure Nginx by creating a new configuration file in /etc/nginx/sites-available/:

$ doas vim /etc/nginx/sites-available/fussel.conf

Add the following configuration to the file:

server {
    listen 80;
    server_name example.com;
    location / {
        proxy_pass http://127.0.0.1:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

Replace example.com with your domain name.

Create a symbolic link to the configuration file in /etc/nginx/sites-enabled/ using the following command:
```
$ doas ln -s /etc/nginx/sites-available/fussel.conf /etc/nginx/sites-enabled/
```
Restart Nginx using the following command:
```
$ doas rcctl restart nginx
```
Run Fussel using Gunicorn in the virtual environment:
```
$ cd /usr/local/fussel/fussel_venv/bin
$ gunicorn -w 4 -b 127.0.0.1:8000 fussel:app
```
This will start Fussel on port 8000.
Open a web browser and navigate to http://example.com (replace example.com with your domain name). You should see the Fussel login page.

Congratulations! You have successfully installed Fussel on OpenBSD.
