Install Iroha 2

This tutorial guides you through the steps to install Iroha 2 and its necessary binaries on your machine.

1. Prerequisites

To install Iroha 2, you need to set up the following first:

• git
• OpenSSL
• Rust Toolchain (v1.60.0 or newer)

TIP: How to Install OpenSSL

Note that in most Linux setups OpenSSL is already available to you.

• Install OpenSSL on Ubuntu:

  $ sudo apt-get install libssl-dev

• Install OpenSSL on macOS using brew:

  $ brew install openssl

Check the OpenSSL installation guide for details.

2. Clone Iroha from GitHub

1. Create a new directory for Iroha. In this tutorial we use Git as an example, but you can name it anything else:

   $ mkdir -p ~/Git

   TIP

   On macOS, if you get the fatal: could not create work tree dir 'iroha': Read-only file system error, that is because the home directory is not a real file system.

   To fix this, create a directory named Git.

2. Enter the directory that you created:

   $ cd ~/Git

3. Clone the iroha GitHub repository:

   $ git clone https://github.com/hyperledger/iroha.git

3. Install Iroha Binaries

To get started you need two of the binaries shipped with Iroha:

• iroha, the main command line tool for accessing the Iroha network as a user. It allows you to manage domains, accounts, and assets, and to query network status and events. To install iroha system-wide, use the following command:

$ cargo install --git https://github.com/hyperledger/iroha.git iroha_cli

• kagami, the tool that generates cryotpgraphic keys, configuration files and other necessary data. To install kagami system-wide, use the following command:

$ cargo install --git https://github.com/hyperledger/iroha.git iroha_kagami
