区块链学习之Fabric安装与运行（虚拟机下CentOS7）
前期配置：
更新源和yum库：
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backupwget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repoyum clean allyum makecacheyum updata（若本地安装，则按之后Go安装包流程来，推荐在线安装）
Docker在线安装：
yum install -y yum-utils \device-mapper-persistent-data \lvm2yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repoyum-config-manager --enable docker-ce-edgeyum-config-manager --enable docker-ce-testyum install docker-ce这一句会有点久，但当安装完成时，即意味着docker安装完成。可通过docker version查看。
注意，如果docker version不行
输入命令行：
service docker restart
可能出现问题：
[root@woai33 jack]# service docker restart
Redirecting to /bin/systemctl restart docker.service
Job for docker.service failed because start of the service was attempted too often. See "systemctl status docker.service" and "journalctl -xe" for details.
To force a start use "systemctl reset-failed docker.service" followed by "systemctl start docker.service" again.输入systemctl status docker.service查看结果：
按这里https://blog.csdn.net/zhangbeizhen18/article/details/85239758试了一遍并不行，但最后发现解决办法：去编辑 /etc/docker/daemon.json，这里的文件错误会导致此类错误，一般将内容修改为：
{
"registry-mirrors":["https://registry.docker-cn.com"]
}
在线安装Docker-compose：
参考教程：https://docs.docker.com/compose/install/
sudo curl -L "https://github.com/docker/compose/releases/download/1.25.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-composesudo chmod +x /usr/local/bin/docker-compose如果输入：docker-compose version 不行，继续输入：用于将文件移入/usr/bin/中
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
本地安装Go：
解压本地已下载好的go压缩包到/usr/local/software/中
tar -C /usr/local/software -xzf go-xxx.tar.gz编辑配置文件并更新路径
vim /etc/profie在最后添加以下两句：
export PATH=$PAHT:/usr/local/software/go/bin
export GOPATH=/opt/gopath再esc i :wq 退出后输入：
source /etc/profile 更新配置 ，最后输入 go version 有显示即可
扩：ftp文件传输
ftp：用户名：主机名；密码：登录密码
打开控制面板—>软件—>功能—>Internet
Fabric安装：
项目路径：https://github.com/hyperledger/fabric
安装git：
yum install git新建文件夹：
mkdir -p /opt/gopath/src/github.com/hyperledger进入此文件夹：
cd /opt/gopath/src/github.com/hyperledger再通过git clone https://github.com/hyperledger/fabric 即可将fabric下载到目前所在目录下，之后通过进入并执行
scripts/bootstrap.sh即可下载镜像
若需要相关镜像，可在docker官网上搜索下载：
例：https://hub.docker.com/r/hyperledger/fabric-kafka/tags 即可得到下载链接：
docker pull hyperledger/fabric-kafka:latest并可通过docker images 查看
实例一：Building Your First Network —— 第一个网络
官方教程：https://hyperledger-fabric.readthedocs.io/en/release-1.4/build_network.html
中文版：https://blog.csdn.net/hugowang/article/details/83113964
注意，第一步，先执行bootstrap.sh，否则，会报错：cryptogen tool not found.exiting
当出现问题时，如果执行后无效，可以试着直接将该文件下载下载进行解压，而不是按教程来https://blog.csdn.net/mellymengyan/article/details/77671185
通过下载需要的包：
https://github.com/hyperledger/fabric/releases/download/v1.4.4/hyperledger-fabric-linux-amd64-1.4.4.tar.gz并将下载的hyperledger-fabric-linux-amd64-1.4.4.tar.gz下载后解压到
/opt/gopath/src/github.com/hyperledger/fabric/scripts/fabric-samples/中。当fabric-samples中有了bin文件夹和first-network时，即可进入first-network开始执行
./byfn.sh generate开始创建网络。
正常配置如图：
开始创建：
最后：通过命令行：
./byfn.sh up即可完成网络的构建
[root@woai33 first-network]# ./byfn.sh up
