3 fabric

下载fabric源码

$ mkdir -p ~/go/src/github.com/hyperledger

$ cd ~/go/src/github.com/hyperledger

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

由于Fabric一直在更新，所有我们并不需要最新最新的源码，需要切换到v1.0.0版本的源码即可：

$ cd ~/go/src/github.com/hyperledger/fabric

$ git checkout v1.0.0

下载docker镜像

$ cd ~/go/src/github.com/hyperledger/fabric/examples/e2e_cli/

$ source download-dockerimages.sh -c x86_64-1.0.0 -f x86_64-1.0.0

这样就可以下载所有需要的Fabric Docker镜像了。由于我们设置了国内的镜像，所以下载应该是比较快的。

下载完毕后，我们运行以下命令检查下载的镜像列表：

[root@hadoop e2e_cli]# docker images

启动Fabric网络并完成ChainCode的测试

我们仍然停留在e2e_cli文件夹，这里提供了启动、关闭Fabric网络的自动化脚本。我们要启动Fabric网络，并自动运行Example02 ChainCode的测试，执行一个命令：

$ ./network_setup.sh up

这个做了以下操作：

7.1编译生成Fabric公私钥、证书的程序，程序在目录：fabric/release/linux-amd64/bin

7.2基于configtx.yaml生成创世区块和通道相关信息，并保存在channel-artifacts文件夹。

7.3基于crypto-config.yaml生成公私钥和证书信息，并保存在crypto-config文件夹中。

7.4基于docker-compose-cli.yaml启动1Orderer+4Peer+1CLI的Fabric容器。

7.5在CLI启动的时候，会运行scripts/script.sh文件，这个脚本文件包含了创建Channel，加入Channel，安装Example02，运行Example02等功能。

最后运行完毕，我们可以看到这样的界面：

===================== All GOOD, End-2-End execution completed =====================

_____ _ _ ____ _____ ____ _____

| ____| | \ | | | _ \ | ____| |___ \ | ____|

| _| | \| | | | | | _____ | _| __) | | _|

| |___ | |\ | | |_| | |_____| | |___ / __/ | |___

|_____| |_| \_| |____/ |_____| |_____| |_____|

如果您看到这个界面，这说明我们整个Fabric网络已经通了。

测试fabric网络

我们仍然是以现在安装好的Example02为例，在官方例子中，channel名字是mychannel，链码的名字是mycc。我们首先进入CLI，我们重新打开一个命令行窗口，输入：

$ docker exec -it cli bash

运行以下命令可以查询a账户的余额：

$ peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'

root@229d9708f2d6:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'

然后，我们试一试把a账户的余额再转20元给b账户，运行命令：

到此一切正常。

关闭网络

最后我们要关闭Fabric网络，首先需要运行exit命令退出cli容器。关闭Fabric的命令与启动类似，命令为：

$ exit

$ cd ~/go/src/github.com/hyperledger/fabric/examples/e2e_cli

$ ./network_setup.sh down

[root@hadoop e2e_cli]# ./network_setup.sh down

setting to default channel 'mychannel'

结束语

到此整个安装测试结束，此篇仅为测试fabric框架在centos 7 中的安装测试。中间坑无数，如：

go语言需要设置GOPATH、GOROOT环境变量，否则运行./network_setup.sh up命令会出现找不到mycc链。

node.js需要gcc编译支持，而yum install安装的gcc版本过低，不能顺利安装，因此需要对gcc版本升级，而升级的时候make实在实在实在太慢了！！！

docker镜像安装，最好在后面写入版本信息，否则下载的可能与git checkout所对应版本不一致，./network_setup.sh up命令时会出现各类奇葩问题。
