Installing Kriss Feed on NixOS

Kriss Feed is a simple and smart (or stupid) feed aggregator written in PHP, with a twist. It allows you to combine and track your favorite feeds with the content that you generate on your own website.

This tutorial will guide you through the installation process of Kriss Feed on NixOS.

Prerequisites

Before you start, make sure you have the following prerequisites:

• A computer running NixOS Latest
• A basic understanding of the command line

Step 1 - Install required packages

First, we need to install some packages that are required to run Kriss Feed. In the terminal, run the following commands:

$ sudo nix-env -i php71 php71-intl php71-phar php71-dom php71-json php71-xml php71-pdo_mysql php71-mbstring

This command installs PHP 7.1 and some required extensions such as intl, phar, dom, json, xml, pdo_mysql, and mbstring.

Step 2 - Download and unzip Kriss Feed

Next, download the latest release of Kriss Feed from the official GitHub repository. For example, you can run the following command to download Kriss Feed version 1.6.1:

$ wget https://github.com/tontof/kriss_feed/archive/v1.6.1.zip

Then, unzip the downloaded file:

$ unzip v1.6.1.zip

Step 3 - Configure PHP

Now, we need to create a configuration file for PHP. Open the configuration file /etc/php.ini with a text editor (such as nano):

$ sudo nano /etc/php.ini

Add the following line at the end of the file:

date.timezone = "UTC"

Then, save and close the file by pressing Ctrl+X, Y, and Enter.

Step 4 - Set up Kriss Feed

Next, we need to set up Kriss Feed. Copy the kriss_feed directory (from the unzipped file in Step 2) to your nginx document root directory:

$ sudo cp -r kriss_feed-1.6.1 /var/www/kriss_feed

Step 5 - Configure Nginx

Finally, we need to configure Nginx to serve Kriss Feed. Open the Nginx configuration file /etc/nginx/sites-enabled/default with a text editor:

$ sudo nano /etc/nginx/sites-enabled/default

Add the following configuration block inside the server block:

location /kriss {
    alias /var/www/kriss_feed;
    index index.php;
    try_files $uri $uri/ /kriss/index.php?$query_string;
}

Then, save and close the file by pressing Ctrl+X, Y, and Enter.

Step 6 - Restart Nginx

Finally, restart Nginx to apply the changes:

$ sudo systemctl restart nginx

Conclusion
