How to Install Uptime Kuma on OpenBSD

Uptime Kuma is an open-source self-hosted monitoring tool that provides a dashboard to track the status of web sites and applications. In this tutorial, we will guide you through the steps necessary to install Uptime Kuma on OpenBSD.

Requirements

Before starting, ensure that you have the following prerequisites:

Access to an OpenBSD server
A non-root user account with sudo privileges
A web server installed on your server, such as Apache or Nginx
Git installed on your server

Step 1: Install Node.js and Yarn

Uptime Kuma requires Node.js to run. To install Node.js, follow these steps:

Update the package manager first by running the following command:
```
$ doas pkg_add -u
```
Install the node and yarn packages by running the following command:
```
$ doas pkg_add yarn node
```

Step 2: Install Uptime Kuma

Clone Uptime Kuma's repository from GitHub using the git command:
```
$ git clone https://github.com/louislam/uptime-kuma.git
```
Change into the newly cloned directory:
```
$ cd uptime-kuma
```
Install the necessary packages using yarn:
```
$ yarn
```

Step 3: Configure Uptime Kuma

Copy the config.sample.json file to config.json using the following command:
```
$ cp config.sample.json config.json
```

Edit the config.json file using your favorite editor, and set the following properties:

"baseUrl": "http://<your_domain_name_or_IP_address>",
"dbPath": "<full_path_to_uptime_kuma_folder>/uptime-kuma/var/data.db",

Step 4: Set up Web Server

Note: This guide assumes that you are using Nginx as your web server.

Create the Nginx server block:

server {
    listen 80;
    server_name <your_domain_name_or_IP_address>;

    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-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_read_timeout 300s;
        proxy_connect_timeout 75s;
        proxy_send_timeout 300s;
    }
}

Save this block in /etc/nginx/sites-available/uptime-kuma file.

Create a symlink to enable this server block:

$ cd /etc/nginx/sites-enabled/
$ ln -s ../sites-available/uptime-kuma .

Restart Nginx to enable these changes:
```
$ doas /etc/rc.d/nginx restart
```

Step 5: Start Uptime Kuma

Start Uptime Kuma using the following command:
```
$ yarn start
```
This will launch the Uptime Kuma dashboard and keep it running in the foreground. To run it in the background, run the following command instead:
```
$ yarn start --silent &
```
You should now be able to access Uptime Kuma by visiting http://<your_domain_name_or_IP_address> in your web browser.

Congratulations! You have successfully installed Uptime Kuma on OpenBSD.
