hyperledger fabric 基础环境搭建（win10下VMware中centos7）一
一、安装环境：centos 7
安装过程中踩了n多的坑，centos7就装了很多次。后来发现，如果选择使用桌面版的centos7，最好选择下载Everything，虽然有10G大小，但是后面遇到的问题会少一点，具体可以参考：https://blog.csdn.net/qq_39135287/article/details/83993574?utm_medium=distribute.pc_relevant.none-task-blog-BlogCommendFromMachineLearnPai2-2.channel_param&depth_1-utm_source=distribute.pc_relevant.none-task-blog-BlogCommendFromMachineLearnPai2-2.channel_param
二、安装环境：docker等
引用了这个链接：https://blog.csdn.net/u010857052/article/details/83931500
包含了docker、docker-compose、go 、git的安装步骤，亲测可行，安装简便。其中从链接第四步开始，本人做了些改动。
其中上图的第3小步设置环境变量时，记得用su命令进入root权限下再用vim /etc/profile，否则不能保存。有前辈建议GOPATH路径最好不要设置在root文件夹下（这个随个人意愿来，不是很重要），因此本人设置如下：
export PATH=$PATH:/usr/local/go/bin
export GOROOT=/usr/local/go
export GOPATH=/home/go/yu
export GOBIN=/home/yu/go/bin
三、下载 fabric源码、fabric-samples源码、fabric镜像
引用了这个链接第三步：https://blog.csdn.net/Sun_Hui_/article/details/100928155
创建并进入 hyperledger 目录 ，最好将$GOPATH改成绝对地址，这样可以避免错误：
mkdir -p /home/yu/go/src/github.com/hyperledger
cd /home/yu/go/src/github.com/hyperledger下载 fabric 源码：
git clone https://github.com/hyperledger/fabric.git将 fabric 切换至 1.4 版本：
cd fabric
git branch -a
git checkout release-1.4下载 docker-images1.4.3共7个 镜像：
cd /gopath/src/github.com/hyperledger/fabric/scripts
./bootstrap.sh需要注意的是，本人下载的版本是hyperledger-fabric-linux-amd64-1.4.3.tar.gz和hyperledger-fabric-ca-linux-amd64-1.4.3.tar.gz，如果下载遇到问题，可以在命令前加上sudo。
使用脚本bootstrap.sh下载文件时，可能会遇到curl: (6) Could not resolve host: nexus.hyperledger.org; 未知的错误这种报错。经查询，问题在于原bootstrap.sh文件中的链接被墙，参考这个链接：https://blog.csdn.net/qq_39800434/article/details/105094313
若是更改bootstrap.sh文件时发现文件是只读，可以使用下面的命令更改权限：
chmod -R 777 scripts/
将bootstrap.sh文件的内容改成如下所示，如果不能运行，可以到https://github.com/hyperledger/fabric/tree/master/scripts去查看最新代码：

fi建议上午5-8点间下载，速度会快上很多，一般9点之后最好就不要下载了，速度很慢卡在中间很难受，不如早起一会顺利下完。hyperledger-fabric-linux-amd64-1.4.3.tar.gz和hyperledger-fabric-ca-linux-amd64-1.4.3.tar.gz下载完之后，还会继续拉取、下载docker相关文件，同样在上述时间段一并完成，节约时间。
四、网络测试
接下来，继续参考：https://blog.csdn.net/u010857052/article/details/83931507的第二步。
在实例化的过程中，可能会遇到：Error: could not assemble transaction, err proposal response was not successful, error code 500, msg error starting container: error starting containe的报错，很可能是因为安装centos7时配置的内存大小和处理器数量不足。本人的配置：
最后，踩坑数次之后，终于完成：
