Hyperledger Fabric 2.2 version environment construction

Preface

Deployment environment: CentOS7.9
install the following tools in advance

• git client
• golang
• docker
• docker-compose
• curl tool

The following is the version for personal use

• git: 2.39.2
• golang: 1.18.6
• docker: 23.0.3
• dockkekr-compose: v2.17.2
• curl: 7.29.0

Official document reference link: jump link , different versions correspond to different official documents, please pay attention to the corresponding version of the document when referring , the docker version cannot be too low, the official requirement is 17.06.2-ce or later

Environment build

• Download fabric source code

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

• Go to the root directory of the source code and view the current branch.

cd fabric/
git branch

• The source code you just downloaded is in the main branch by default.

• Switch to the branch corresponding to version 2.2

git checkout -b release-2.2 origin/release-2.2
git branch

• Enter the scripts folder of the fabric source code

cd scripts/
ls -l

You can see that there is a bootstrap.sh file

• Execute script to install

sh bootstrap.sh 

• If you do not have executable permissions, use the following command to modify the permissions

chmod +x bootstrap.sh 

The execution script mainly does the following things:

1. Download the source code of fabric-samples and switch to the corresponding version
2. Download hyperledger-fabric-linux-amd64-2.2.10.tar.gz. After decompression, the bin and config directories will be generated.
3. Download hyperledger-fabric-ca-linux-amd64-1.5.5.tar.gz and unzip it to generate the bin directory.
4. Download the docker image related to hyperledger fabric and modify the image tag to latest

• After the script is executed, the following content is mainly generated:

1. fabric-samples source code
   
2. Switching to fabric-samples will have two directories: bin and config
3. docker image
   

• Modify the executable permissions of the bin and config directories, enter the fabric-samples source code root directory, and execute the following command

chmod -R +x bin/
chmod -R +x config/

• Enter the test-network directory of fabric-samples

cd test-network/

• Start with the following command

sh network.sh up

• Using the docker command, you can see that the following containers are started:

• Create channels

./network.sh createChannel -c mychannel

The following content appears, indicating that the channel is successfully created. After the channel is successfully created, it is added to the node.

• Deploy contract

./network.sh deployCC -ccn contract-name -ccv 1 -ccs 1 -ccp fabric-samples/asset-transfer-basic/chaincode-go -ccl go

The meanings of the parameters of the above command:
deployCC: This script comes with the source code, under fabric-samples/test-network/scripts/
-ccn: contract name
-ccv: contract version
-ccl: contract language, java, go, etc.
-ccs: the sequence of the contract, which must be an integer
-ccp: the path where the contract is located
Other parameters can be found in the fabric-samples/test-network/scripts/utils.sh script, which has a detailed description of each parameter .
For the deployed contract, you can define it yourself or use the official example. After the

above command of fabric-samples/asset-transfer-basic is successfully executed, the official example will finally output the following results:

• If you want to shut down the network, execute the following command

./network.sh down

The above command will close and remove all started docker images.

problem solved

• During the contract deployment process: dial tcp 142.251.42.241:443: connect: connection refused
  
  Solution: Change the proxy address and execute the following command

  go env -w GOPROXY=https://goproxy.cn
  

Finish

The above is the construction of the Hyperledger Fabric 2.2 version environment. If you have any questions, please feel free to communicate.
