1. Download Fabric (version 2.3.3)
[root@localhost ~]# mkdir -p $GOPATH/src/github.com/hyperledger # Create download directory [root@localhost ~]# cd $GOPATH/src/github.com/hyperledger #Enter directory [root@localhost hyperledger]# git clone https://github.com/hyperledger/fabric.git
Download is too slow, wait, etc. (you can use scientific Internet tools)
The following errors may occur during downloading. Try several more times
two Installation example, binary and Docker image (see method 3 directly)
(1) Method 1 (unsuccessful): execute directly according to the official website
curl -sSL https://bit.ly/2ysbOFE | bash -s # official website
(2) Method 2 (unsuccessful): directly execute the bootstrap.sh script ， Same error as method 1
#Enter the fabric/scripts directory cd fabric/scripts #Execute bootstrap.sh ./bootstrap.sh
(3) Method 3: directly download the file in bootstrap.sh
See the relevant contents in the bootstrap.sh script to get three download addresses

pullBinaries() {
echo "===> Downloading version ${FABRIC_TAG} platform specific fabric binaries"
#Download fabric binary file
download "${BINARY_FILE}" "https://github.com/hyperledger/fabric/releases/download/v${VERSION}/${BINARY_FILE}"

#Download the fabric CA binary

......
}
......
BINARY_FILE=hyperledger-fabric-${ARCH}-${VERSION}.tar.gz
CA_BINARY_FILE=hyperledger-fabric-ca-${ARCH}-${CA_VERSION}.tar.gzFirst, Download fabric sample and try to use git and wget. After multiple error reports (as shown in the figure below), download it directly in windows, and then transfer it to the corresponding directory of CentOS 7 (as shown in the figure below). Download address: GitHub - hyperledger/fabric-samples
Upload to the fabric/scripts directory at the same level as the bootstrap.sh script
Secondly, download the fabric binary file (version 2.3.3), use wget to report an error, download it directly in windows, and then upload it to CentOS 7 for decompression. The download address is: https://github.com/hyperledger/fabric/releases/download/v2.3.3/hyperledger-fabric-linux-amd64-2.3.3.tar.gz
Finally, download the fabric CA binary file (version 1.5.2), close the firewall and surf the Internet scientifically at the same time. If wget reports an error, it is recommended to download it in the windows browser, then upload it to CentOS 7 and unzip it. The download address is: https://github.com/hyperledger/fabric-ca/releases/download/v1.5.2/hyperledger-fabric-ca-linux-amd64-1.5.2.tar.gz
[root@localhost scripts]# systemctl stop firewalld.service #Turn off firewall [root@localhost scripts]# firewall-cmd --state #View firewall status not running [root@localhost scripts]# wget https://github.com/hyperledger/fabric-ca/releases/download/v1.5.2/hyperledger-fabric-ca-linux-amd64-1.5.2.tar.gz # Download
The above two compressed files are downloaded to the fabric/scripts directory
Unzip the file into fabric samples
[root@localhost scripts]# tar -xvf hyperledger-fabric-linux-amd64-2.3.3.tar.gz -C fabric-samples [root@localhost scripts]# tar -xvf hyperledger-fabric-ca-linux-amd64-1.5.2.tar.gz.tar.gz -C fabric-samples
Execute the. / bootstrap.sh script
[root@localhost scripts]# ./bootstrap.sh -b #Pull only the image file of fabric
Binary files can be used for global settings
[root@localhost scripts]# cd fabric-samples/bin #Enter the bin directory [root@localhost bin]# ls configtxgen cryptogen fabric-ca-client idemixgen osnadmin configtxlator discover fabric-ca-server orderer peer [root@localhost bin]# cp * /usr/local/bin #copy the binary file to / usr/local/bin
3. Start the test network
[root@localhost bin]# cd .. #Go back to the fabric samples directory [root@localhost fabric-samples]# cd test-network #Enter the test network directory [root@localhost test-network]# ./network.sh #Start test network script -bash: ./network.sh: Permission denied #Prompt that you do not have permission to execute the network.sh file [root@localhost test-network]# chmod u+x network.sh #to grant authorization [root@localhost test-network]# ./network.sh #Execute the test network script again [root@localhost test-network]# ./network.sh up #Start test network
4. Create a channel
[root@localhost test-network]# ./network.sh createChannel
5. Installation go dependency
[root@localhost fabric-samples]# cd asset-transfer-basic/chaincode-go/ #Enter directory [root@localhost chaincode-go]# ls #View directory contents assetTransfer.go chaincode go.mod go.sum #There is no vendor directory at this time [root@localhost chaincode-go]# go env #View go environment configuration ...... GOPROXY="https://proxy.golang.org,direct "# view proxy settings ...... [root@localhost chaincode-go]# go env -w GOPROXY=https://goproxy.cn # change proxy [root@localhost chaincode-go]# go mod vendor #Installation dependency [root@localhost chaincode-go]# ls #View directory contents assetTransfer.go chaincode go.mod go.sum vendor #The vendor directory appears
6. Start a chain code in the channel
[root@localhost chaincode-go]# cd .. [root@localhost asset-transfer-basic]# cd .. [root@localhost fabric-samples]# cd test-network #Enter the test network directory [root@localhost test-network]# ./network.sh deployCC -ccn basic -ccp ../asset-transfer-basic/chaincode-go -ccl go #Start a chain code in the channel (official website)
If an error occurs when starting the chain code:. / network.sh: line 270: scripts/deployCC.sh: Permission denied
It is better to authorize all. sh files in the directory to avoid authorization errors when executing later
[root@localhost test-network]# cd scripts [root@localhost scripts]# ls -l total 36 -rw-r--r--. 1 root root 2284 Oct 25 02:33 configUpdate.sh -rwxr--r--. 1 root root 2562 Oct 25 02:33 createChannel.sh -rw-r--r--. 1 root root 11675 Oct 25 02:33 deployCC.sh -rw-r--r--. 1 root root 3476 Oct 25 02:33 envVar.sh drwxr-xr-x. 2 root root 58 Oct 25 02:33 org3-scripts -rw-r--r--. 1 root root 1941 Oct 25 02:33 setAnchorPeer.sh -rw-r--r--. 1 root root 7269 Oct 25 02:33 utils.sh [root@localhost scripts]# chmod -R +x ../scripts #All files in the directory are authorized [root@localhost scripts]# ls -l total 36 -rwxr-xr-x. 1 root root 2284 Oct 25 02:33 configUpdate.sh -rwxr-xr-x. 1 root root 2562 Oct 25 02:33 createChannel.sh -rwxr-xr-x. 1 root root 11675 Oct 25 02:33 deployCC.sh -rwxr-xr-x. 1 root root 3476 Oct 25 02:33 envVar.sh drwxr-xr-x. 2 root root 58 Oct 25 02:33 org3-scripts -rwxr-xr-x. 1 root root 1941 Oct 25 02:33 setAnchorPeer.sh -rwxr-xr-x. 1 root root 7269 Oct 25 02:33 utils.sh [root@localhost scripts]# cd .. [root@localhost test-network]# ./network.sh deployCC -ccn basic -ccp ../asset-transfer-basic/chaincode-go -ccl go
