Fabric开发（二）ubuntu下编译Fabric2.2.0
今天我们用Ubuntu16.04.6在本地编译一下Fabric2.2.0版本。因为在编译过程中有很多细节，需要注意。
1、安装前准备：
安装 git、curl、pip
sudo apt-get install git
sudo apt-get install curl
sudo apt-get install python-pip
pip install --upgrade pip
2、安装go
我这次安装的是go14.4，因为要编译Fabric2.2.0，对Go版本需要>14.1
wget https://storage.googleapis.com/golang/go1.14.4.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.14.4.linux-amd64.tar.gz
接下来编辑当前用户的环境变量：
vi ~/.profile
编辑保存并退出vi后，记得把这些环境载入：
source ~/.profile
我们把go的目录GOPATH设置为当前用户的文件夹下，所以记得创建go文件夹
cd ~
mkdir go
这里强调一下，编译Fabric需要安装go的工具包。安装如下：
mkdir –p $GOPATH/src/golang.org/x
cd $GOPATH/src/golang.org/x
git clone https://github.com/golang/tools.git
等tools下载完毕，我们可以运行以下命令来安装Fabric可能用到的Go工具：
go get github.com/kardianos/govendor
go get github.com/golang/lint/golint
go get golang.org/x/tools/cmd/goimports
go get github.com/onsi/ginkgo/ginkgo
go get github.com/axw/gocov/...
go get github.com/client9/misspell/cmd/misspell
go get github.com/AlekSi/gocov-xml
go get github.com/golang/protobuf/protoc-gen-go
3. 第三方库安装
Fabric依赖的第三方库里面，有些库又依赖了其他库，而这些库是需要我们先手动准备好的。比如libltdl-dev，这是PKCS11用到的一个库，我们需要安装：
sudo apt-get install libltdl-dev
4.Docker安装
卸载旧版本docker
sudo apt-get remove docker docker-engine docker.io
更新系统软件
sudo apt-get update
安装依赖包
sudo apt-get install \
apt-transport-https \
ca-certificates \
curl \
software-properties-common
添加官方密钥
执行该命令时，如遇到长时间没有响应说明网络连接不到docker网站，需要使用代-理进行。
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
显示OK,表示添加成功.
添加仓库
sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"
再次更新软件
sudo apt-get update
安装docker
如果想指定安装某一版本，可使用 sudo apt-get install docker-ce= 命令，把替换为具体版本即可。
以下命令没有指定版本，默认就会安装最新版
sudo apt-get install docker-ce
查看docker版本
docker -v
5…docker-compose安装
下载docker-compose
sudo curl -L https://github.com/docker/compose/releases/download/1.17.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
授权
sudo chmod +x /usr/local/bin/docker-compose
查看版本信息
docker-compose --version
6.下载 fabric源码、fabric-samples源码、fabric镜像
我们可以使用Git命令下载源码，首先需要建立对应的目录，然后进入该目录，Git下载源码：
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v2.2.0版本的源码即可：
cd ~/go/src/github.com/hyperledger/fabric
git checkout v2.2.0
我们现在开始编译
cd ~/go/src/github.com/hyperledger/fabric
make release
显示如下，编译完成
