Hyperledger Fabric2.2.1 安装测试

​ 操作系统（本文Ubuntu 18.04 LTS 虚拟机）， 最后在Window操作系统中再安装一个远程连接工具（如XShell或SecureCRT），方便连接并操作Ubuntu系统。

1.换源，更换apt的下载源，官方下载源很慢，我们需要更换到国内的镜像站

1.1 进入 /etc/apt 目录

cd /etc/apt 

1.2 备份 sources.list 文件

sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup

1.3 打开 sources.list 文件进行修改并添加阿里云镜像

#在文件最前面添加即可
sudo vi /etc/apt/sources.list  

#  阿里源
