How to install Fess on nixOS

This tutorial will guide you through the installation of Fess, which is a search engine platform that enables you to quickly search and index data. Fess can be installed on nixOS and we will use the nix package manager to install Fess.

Prerequisites

Make sure you have a nixOS installed on your system. Also, ensure that the system has Java 8 installed. You can check your Java version by running the command java -version.

Installation

  1. Open the terminal and update the nixOS package manager by running the command:

    sudo nix-channel --update

  2. Next, install the Fess package by running the following command:

    sudo nix-env -iA nixos.fess

    This command will install Fess, along with its dependencies, on your system.

  3. After installation, you need to configure Fess. The configuration file is located at /etc/fess/fess.in.sh. You can create a backup of this file before you modify it:

    sudo cp /etc/fess/fess.in.sh /etc/fess/fess.in.sh.bkp

  4. Open the /etc/fess/fess.in.sh file using the text editor of your choice:

    sudo nano /etc/fess/fess.in.sh

    Here, you need to modify the following variables:

    JAVA_HOME=/usr/lib/jvm/java-1.8-openjdk
APP_HOME=/var/lib/fess
ES_HEAP_SIZE=2g
HTTP_PORT=8080
HTTPS_PORT=8443
    • JAVA_HOME should point to the Java 8 installation directory.
    • APP_HOME is the directory where Fess will store its data files. You can change this directory if you want.
    • ES_HEAP_SIZE is the maximum amount of memory Fess can use. Change this value to suit your needs.
    • HTTP_PORT and HTTPS_PORT are the HTTP and HTTPS ports used by Fess.

  5. Finally, start the Fess service:

    sudo systemctl start fess.service

    You can also enable the Fess service to start automatically at boot:

    sudo systemctl enable fess.service

  6. Access the Fess web interface by opening a web browser and navigating to http://localhost:8080.

    Congratulations, you have successfully installed Fess on nixOS!
