Tutorial: How to Install LinkAce on NixOS Latest

Introduction

LinkAce is an open-source self-hosted bookmarking application that allows users to save and organize links, articles, and other web resources. In this tutorial, we’ll cover how to install LinkAce on the latest version of NixOS.

Prerequisites

Before we start, ensure that you have the following:

• A NixOS system
• A basic knowledge of the command line
• An administrative user with sudo privileges to install packages and modify the system configuration.

Step 1: Update NixOS

Ensure that your NixOS system is up to date by executing the following command:

$ sudo nixos-rebuild switch

Step 2: Install Required Dependencies

Before installing LinkAce, some dependencies need to be installed. Use the following command:

$ sudo nix-env -i postgresql
$ sudo nix-env -i redis
$ sudo nix-env -i nodejs

Step 3: Create a PostgreSQL Database

Next, you need to create a PostgreSQL database for LinkAce. Execute the following commands:

$ sudo su - postgres
$ createuser linkace -P
$ createdb linkace -O linkace
$ exit

Step 4: Download and Extract LinkAce

Download the LinkAce archive from the official website using the following commands:

$ cd /tmp
$ curl -LO https://github.com/Kovah/LinkAce/releases/download/1.14.0/linkace_1.14.0_linux_amd64.tar.gz

Extract the downloaded archive:

$ tar xzf linkace_1.14.0_linux_amd64.tar.gz

Step 5: Configure LinkAce

Create a configuration file for LinkAce using the following command:

$ sudo nano /etc/linkace/config.yml

Copy and paste the following code into the file:

app:
  url: "http://localhost"
  port: 5000
  secret: "YOUR_APP_SECRET"

database:
  type: "postgres"
  host: "localhost"
  port: 5432
  username: "linkace"
  password: "YOUR_PASSWORD"
  database: "linkace"

redis:
  host: "localhost"
  port: 6379

mail:
  host: "smtp.gmail.com"
  port: 587
  username: "YOUR_USERNAME@gmail.com"
  password: "YOUR_PASSWORD"
  from: "YOUR_USERNAME@gmail.com"

timezone: "UTC"

Replace "YOUR_PASSWORD" with the password you have set for the PostgreSQL user "linkace". Also, replace "YOUR_USERNAME" and "YOUR_PASSWORD" in the "mail" section with your Gmail username and password.

Step 6: Start LinkAce

Start the LinkAce application using the following command:

$ cd /tmp/linkace_1.14.0_linux_amd64
$ ./linkace

You should see the following message:

Open your web browser and visit http://localhost:5000. That’s it! You have successfully installed LinkAce on your NixOS system.
