Hyperledger Fabric's environment on Ubuntu

First install Ubuntu on the VMware Workstation virtual machine, configure the environment, adjust the Chinese language, the resolution, open the terminal.

PS: After installing Ubuntu system if you find that files with Windows system can not replicate with each other, the web looked up a lot of tutorials, found that are not available, the method can be implemented as follows:

Open Terminal, enter:

1:sudo Apt-get Autoremove Open-vm-tools

2:sudo Apt-get Install Open-vm-tools-desktop

And then restart

Next, the deployment of the fabric is formally started:

First step: Configure the basic Ubuntu environment

Install Vim:

sudo apt-get install vim

To install Curl:

1:sudoapt-get Update

2:SUDOAPT Install Curl

To install Git:

sudo apt-get install git

Step Two: Install the Go language and match environment variables

Install the Go language:

sudo apt-getinstall Golang

To view the version of the Go language:

Go version

To see the installation path and environment variables for go:

Go env

After you install the Go language, you also need to configure Go environment variables for the language:

Vi ~/.profile//Edit the current user's environment variables

At the end of profile, add the following:

Export path= $PATH:/usr/local/go/bin (depending on your situation)//set as your own go install directory

Export Goroot=/usr/local/go

Exportgopath= $HOME/go

Exportpath= $PATH: $HOME/go/bin

Step three: Install Docker.

Ubuntu comes with its own Docker:

sudo apt-get update

sudo apt-get install-y Docker.io

sudo ln-sf/usr/bin/docker.io/usr/local/bin/docker

Test: sudo docker info

If you encounter problems, you can deactivate and start Docker.

Deactivation: sudo service docker stop

Enable: sudo service docker start

Then modify the permissions of the current user:

sudo usermod-ag Docker $USER

Add Mirroring Acceleration:

Create a Docker file

sudo mkdir-p/etc/docker

sudo gedit/etc/docker/daemon.json

Add the following information to the Daemon.json file:

{"Registry-mirrors": ["https://registry.docker-cn.com"]}

Docker-compose the installation

Run the following command to download the latest version of Docker-compose:

sudo curl-lhttps://github.com/docker/compose/releases/download/1.18.0/docker-compose-' uname-s '-' uname-m '-o/usr/ Local/bin/docker-compose

Change the permissions of the binaries so that they can run:

sudo chmod +x/usr/local/bin/docker-compose

Test installation:

Docker-compose–version

Fourth Step, Fabric Source Download

To create a folder under GO environment variable, switch to this folder:

CD ~/go/src/github.com/hyperledger

Download full source with git command

git clone https://github.com/hyperledger/fabric.git

Because we are just building the environment. No need for the latest code, so just switch to the v1.0.0 large version.

CD ~/go/src/github.com/hyperledger/fabric//Enter the fabric directory git checkout v1.0.0

Fabric Source Download Complete!!

Fifth step, the download of the Fabric docker image

Switch to the examples file for fabric:

CD ~/go/src/github.com/hyperledger/fabric/examples/e2e_cli/

To run the command download Image:

SOURCE Download-dockerimages.sh-c x86_64-1.0.0-f x86_64-1.0.0

Once the download is complete, we run the following command to check the downloaded image list:

Docker images

Sixth step, start the fabric network and complete the Chaincode test

To switch to the Examples/e2e_cli file, start the test example:

CD ~/GO/SRC/GITHUB.COM/HYPERLEDGER/FABRIC/EXAMPLES/E2E_CLI

Start:./network_setup.sh up

Close:./network_setup.shdown

When executing the./byfn.sh-m up, the error message is as follows,

Error:for Orderer.example.comCannot Create container for service orderer.example.com:Conflict. Thecontainer name "/orderer.example.com" is already on use by container "d6621116cf0d1ab108277893178ba29acreating Peer0.org1.example.com ... error

Workaround: This is caused by a naming conflict when the exception was aborted and now runs again. Knowing the problem, it's not that hard to solve. First enter Docker ps-a check is not really a naming conflict, if yes, Docker Ps-qa | Xargs Docker RM removes the naming conflict. Enter again./byfn.sh-m up, wait a minute, just like the official web.
