[root@localhost ~]# mkdir -p $GOPATH/src/github.com/hyperledger  # 创建下载目录
[root@localhost ~]# cd $GOPATH/src/github.com/hyperledger    #进入目录
[root@localhost hyperledger]# git clone https://github.com/hyperledger/fabric.git

下载太慢了，要等等等（可以使用科学上网工具）

下载时可能出现下面错误，多尝试几次

2. 安装示例、二进制和 Docker 镜像（直接看方法三）

（1）方法一（未成功）：按官网直接执行

curl -sSL https://bit.ly/2ysbOFE | bash -s  #官网

（2）方法二（未成功）：直接执行bootstrap.sh脚本，与方法一相同的错误

#进入fabric/scripts目录
cd fabric/scripts
#执行bootstrap.sh
./bootstrap.sh

（3）方法三：直接下载bootstrap.sh中的文件

参见bootstrap.sh脚本中相关内容，得到3个下载地址

VERSION=2.3.3       #fabric版本
......
CA_VERSION=1.5.2    #fabric-ca版本
ARCH=$(echo "$(uname -s|tr '[:upper:]' '[:lower:]'|sed 's/mingw64_nt.*/windows/')-$(uname -m | sed 's/x86_64/amd64/g')")
......
cloneSamplesRepo() {
    ......
        #下载fabirc-samples
        git clone -b main https://github.com/hyperledger/fabric-samples.git && cd fabric-samples
    ......
}
......
pullBinaries() {
    echo "===> Downloading version ${FABRIC_TAG} platform specific fabric binaries"
    #下载fabric二制进文件
    download "${BINARY_FILE}" "https://github.com/hyperledger/fabric/releases/download/v${VERSION}/${BINARY_FILE}"
    ......
    #下载fabric-ca二进制文件
    download "${CA_BINARY_FILE}" "https://github.com/hyperledger/fabric-ca/releases/download/v${CA_VERSION}/${CA_BINARY_FILE}"
    ......
}
......
BINARY_FILE=hyperledger-fabric-${ARCH}-${VERSION}.tar.gz
CA_BINARY_FILE=hyperledger-fabric-ca-${ARCH}-${CA_VERSION}.tar.gz

首先，下载fabric-sample，尝试使用git与wget，多次执行报错后（如下图），直接在windows中下载，然后传到centos7对应的目录下（如下图目录图）。下载地址：GitHub - hyperledger/fabric-samples

上传到fabric/scripts目录中，与bootstrap.sh脚本同层级

其次，下载fabric二进制文件（版本2.3.3）使用wget报错，直接在windows下载，然后上传到centos7中解压。下载地址为：https://github.com/hyperledger/fabric/releases/download/v2.3.3/hyperledger-fabric-linux-amd64-2.3.3.tar.gz

最后，下载fabric-ca二进制文件（版本1.5.2），需关闭防火墙，同时科学上网。如果wget报错，建议还是在windows浏览器中下载，然后上传到centos7中解压。下载地址为：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  #关闭防火墙
[root@localhost scripts]# firewall-cmd --state    #查看防火墙状态
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 #下载

以上2个压缩文件都下载到了fabric/scripts目录中

解压文件至fabric-samples中

[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

执行./bootstrap.sh脚本

[root@localhost scripts]# ./bootstrap.sh -b  #仅拉取fabric的镜像文件

设置全局都可以使用二进制文件

[root@localhost scripts]# cd fabric-samples/bin  #进入bin目录
[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  #将二进制文件copy至/usr/local/bin下

3. 启动测试网络

[root@localhost bin]# cd ..                           #回到fabric-samples目录
[root@localhost fabric-samples]# cd test-network      #进入test-network目录
[root@localhost test-network]# ./network.sh           #启动测试网络脚本
-bash: ./network.sh: Permission denied                #提示执行network.sh文件时没有权限
[root@localhost test-network]# chmod u+x network.sh   #授权
[root@localhost test-network]# ./network.sh           #再次执行测试网络脚本
[root@localhost test-network]# ./network.sh up        #启动测试网络

4. 创建通道（channel）

[root@localhost test-network]# ./network.sh createChannel

5. 安装go依赖

[root@localhost fabric-samples]# cd asset-transfer-basic/chaincode-go/  #进入目录
[root@localhost chaincode-go]# ls                                       #查看目录内容
assetTransfer.go  chaincode  go.mod  go.sum                             #此时没有vendor目录
[root@localhost chaincode-go]# go env                                   #查看go环境配置
......
GOPROXY="https://proxy.golang.org,direct"                               #查看代理设置
......
[root@localhost chaincode-go]# go env -w GOPROXY=https://goproxy.cn     #更改代理
[root@localhost chaincode-go]# go mod vendor                            #安装依赖
[root@localhost chaincode-go]# ls                                       #查看目录内容
assetTransfer.go  chaincode  go.mod  go.sum  vendor                     #此时出现vendor目录

6. 在通道启动一个链码

[root@localhost chaincode-go]# cd ..
[root@localhost asset-transfer-basic]# cd ..        
[root@localhost fabric-samples]# cd test-network    #进入到test-network目录
[root@localhost test-network]# ./network.sh deployCC -ccn basic -ccp ../asset-transfer-basic/chaincode-go -ccl go   #在通道中启动一个链码（官网）

若启动链码时出现错误：./network.sh: line 270: scripts/deployCC.sh: Permission denied

则去授权，最好将目录下的所有.sh文件都授权，避免之后执行时再出现授权错误

[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

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        #目录下所有文件都授权
[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

7. 与网络交互
