Blockchain is a popular technology nowadays, where IBM Hyperledger (open source) is the leader in the alliance chain. IBM has the relevant courses. The following is the entire process of building hyperledger fabric in your own Ubuntu development environment for reference. First, the previous step diagram (the original is not carefully encrypted by the DSM, can not be restored only screenshots):2/Instructor Pre-given the installation package gave me a

First let's look at an example first. We know that under the *nix, unameThe command is to view the release version of the system. You can write a fabric script like this: From Fabric.api import Rundef host_type (): Run (' uname-s ') By saving the above script as fabfile.py, you can fab execute the Host_type script on multiple hosts by command: $ fab-h Localhost,linuxbox Host_type[localhost] run:uname-s[localhost] out:darwin[linuxbox] run:uname-s[lin

Fabric Source Code Analysis--Preface Individuals are non-go programmers, but no way, the fabric project is written with go. The additional use of Docker,grpc,protocol Buffer,shell scripts, Yaml profiles, cryptographic certifications, and so on, is Google, or a variety of open source technologies. and from github to download source files, source code, tools, pre-configuration files, samples, sub-projects, d

Python uses the Fabric module for automated O M, and pythonfabric Overview: Fabric is an SSH command line tool based on Python. It simplifies SSH Application Deployment and system management tasks. It provides basic system operation components, it can implement local or remote shell commands, including command execution, file upload, download, and complete execution log output.

Fabric is a Python library. as long as the target machine supports ssh access, fabric can be used for remote operations (such as running shell commands on host2 on host1). Obviously, because fabric is a Pythonpackage, other Pythonpackage can be imported to fabric-specific fabfile. in the py script,

Since my boss suddenly gave me an IBM Blockchain course website, I taught myself to finish two lessons from the blockchain provided by IBM and complete the compose-playground of this blockchain component in the fabric framework. This stand-alone construction is relatively simple, IBM's course has after-school this component related exercises and the document, therefore spent 2 days or so completed. Then the boss let me build a multi-machine cluster

When using shell commands for complex operations, the code tends to be complex and difficult to understand, and the Python scripting language is the equivalent of developing a common application, so maintenance and expansion are simpler, More importantly, the Python Ops tool fabric can automatically log on to other servers for a variety of operations, which is hard to do with the shell, but using the fabric
