git clone https://github.com/bitholla/hollaex-kit.git

HollaEx Kit is a full package with the necessary directory structure, templates, and even a full web server for a HollaEx Exchange.

Installation

The first step is to install HollaEx CLI, a Command-Line tool that simplifies the operation of your HollaEx Kit. You should go into the HollaEx Kit path first to run any further commands.

cd hollaex-kit

Run the CLI installer by using the command below.

bash install.sh

Starting from the HollaEx Kit version v1.0.3, the installer will automatically install docker, docker-compose, and jq if you don't have them already on you machine. Currently the installer is only supporting Debian (Ubuntu) based distros with apt-get for the installation.

Once everything is done, it's time to set up your exchange!

Please proceed to the Setup section next.

HollaEx for Windows

HollaEx Kit is designed for Unix since most professional servers are running on a Unix-based system. However, don't worry! We understand that and this windows guide is here to help.

Thanks to Microsoft, they recently released a cool technology called WSL 2 (Windows Subsystem for Linux 2), which allows Linux application works on native Windows.

Here we guide you on how to get started on your Windows Environment by using WSL 2 and Ubuntu.

Enabling WSL 2

You can follow this document by Microsoft to enabled WSL 2 on your Windows PC.

Installing Ubuntu for WSL 2

You can download Ubuntu at Microsoft Store after enabling the WSL 2.

Installing dependencies

The software mentioned below are dependencies that should be manually installed on your Ubuntu environment.

• Latest docker

• Latest docker-compose

Catching up with HollaEx

Once WSL 2 and Ubuntu are fully set on your computer, You can go back to our general document and proceed to get HollaEx Kit for your exchange.

Keep that in mind that HollaEx on Windows is still only recommended for testing purposes. If you are considering to build a production-ready exchange, Please choose Linux.

HollaEx for macOS

HollaEx is compatible with the Unix environment. Since macOS is the Unix, there are no difficulties to run the HollaEx on macOS. But, the auto dependencies installer would not work for macOS. This page describes a way to install the required dependencies on your Mac.

Installing dependencies

Software mention below are dependencies that should be manually installed on your Mac.

• Latest docker

• Latest docker-compose

• Homebrew (Package Management Software) - To install jq

Installing Docker

You can follow this document to install Docker and Docker compose on your Mac.

Click the Docker menu in the top status bar and select Preferences.

Go to Resources and increase Memory to 4GB manually, and click the "Apply&Restart" button.

Installing jq with Homebrew

The most efficient way to install jq on a Mac would probably be using homebrew. Follow the simple step below to install brew on your Mac.

Open the Terminal application, and then enter the following command into a single line

ruby -e "$(culr -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Enter the administrator password to begin installation (It would take a while depending on the speed of your Mac and internet connection). You will see the "Installation successful!" message once completed.

Start installing jqby typing the command below:

brew install jq
