1. Environment installation
1.1 Install git
The command is as follows: apt installl git
View version information: git version
1.2 Install docker
The command is as follows: apt install docker-ce
View version information: docker version
Add accelerator:
curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://a52236d2.m.daocloud.io
This script can add --registry-mirror to your Docker configuration file /etc/docker/daemon.json
Restart the docker service to make the accelerator take effect:
sudo systemctl restart docker.service
1.3 Install docker-compose
The command is as follows:
curl -L https://get.daocloud.io/docker/compose/releases/download/1.17.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-composeAdd execute permission:
sudo chmod +x /usr/local/bin/docker-composeView version information:
docker-compose --version1.4 Install go
Unzip the resource file, the command is as follows: tar -C /usr/local -zxf package.tar.gz
Add environment variables: vi /etc/profile
The content is as follows:
export GOROOT=/usr/local/go
export GOPATH=/opt/gopath
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
To make the configuration take effect:
source /etc/profile
View version information
go version
2. Build the network
2.1 Download fabric-samples
The command is as follows:
cd / opt
git clone -b master https://github.com/hyperledger/fabric-samples.git
cd fabric-samples
2.2 Download fabric tools ( cryptogen, configtxgen, etc. )
Since the URL provided by the official website cannot be accessed, you can download the tool through the script in the fabric/scripts directory
First download the fabric code Download address: https://github.com/hyperledger/fabric.git switch to the corresponding branch
mkdir -p /opt/gopath/src/github.com/hyperledger
cd /opt/gopath/src/github.com/hyperledger
Copy the fabric source code to the /opt/gopath/src/github.com/hyperledger directory
Authorize the fabric directory
chmod -R +x fabric
Go to the scripts directory
This article uses the script tool of version 1.0.1
Open the script and you can see that the script functions: download tools, pull images and modify tags
After the execution is completed, a bin directory will be generated in the current directory, and this directory will be added to the environment variable to ensure the normal use of the tool class.
The configuration is as follows:
vi /etc/profile
添加：export FABRIC_TOOL=/opt/gopath/src/github.com/hyperledger/fabric/scripts/bin
To make the configuration take effect:
source /etc/profile
2.3 Start the network
Enter the fabric-sample/first-network directory
execute the script command
./byfn.sh -m up
to start the network
At startup, the docker-compose-cli.yaml configuration file is used to start the container by default, and the startup configuration file can be modified by -f
Common commands:
2.4 Status after startup
Because script.sh is automatically executed after the cli container is started
The script will be automatically executed, and it will work:
1. Generate channel.block file
2. Add the peer of the organization to the channel
3. Deploy chaincode and perform invoke and query operations
Eventually we will see a container like this:
Contains: four peer contract containers, three and one order container
Note: Generally, we do not need to automatically publish the contract when starting a network environment. You can comment out the cmd configured by the cli container in docker-compose-cli.yaml (you need to manually create a channel and add nodes to the channel). You can also modify the script The .sh script removes the part of the deployment contract or modifies it into its own contract.
At this point, the creation of the Fabric network is complete!
