粗略分析hyperledger-fabric之e2e_cli是如何开启网络

本文主要是介绍粗略分析hyperledger-fabric之e2e_cli是如何开启网络，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、sudo ./network_setup.sh up

这条命令是如何为我们开启网络？通过几天的查看，我大致理清了他的顺序。在这里分享出来，如有不对，还望指出。
我们还是先看看这个shell文本里的内容：

elif [ "${UP_DOWN}" == "down" ]; then ## Clear the networknetworkDown 
elif [ "${UP_DOWN}" == "restart" ]; then ## Restart the networknetworkDownnetworkUp
elseprintHelpexit 1
fi

阅读这个shell需要一些基础，我也是刚看完shell的一些基本语法才勉强理解，下面我用一张图表示他的启动顺序。

那么这里面最关键的地方有那些呢？首先这条语句：

source generateArtifacts.sh $CH_NAME

无形之间将我们带到了另一个shell文本，那就是同目录下的generateArtifacts.sh，下面我们接着往下看。

#!/bin/bash +x

}generateCerts
replacePrivateKey
generateChannelArtifacts

此文件主要是用来生成主要的配置文件如私钥和证书，有通道证书之类的。下面这张图是它执行的顺序。

其次语句：

CHANNEL_NAME=$CH_NAME TIMEOUT=$CLI_TIMEOUT docker-compose -f $COMPOSE_FILE up -d 2>&1

其实就是：docker-compose -f docker-compose-cli.yaml up是不是感觉很熟悉呢？接下来我们接着看docker-compose-cli.yaml文件。

这个文件的作用就是启动一系列的容器，当你看到下面内容的时候，就是此配置文件的作用：

Creating peer1.org2.example.com ... done
Creating cli ... done
Creating orderer.example.com ...
Creating peer0.org2.example.com ...
Creating peer1.org1.example.com ...
Creating peer0.org1.example.com ...
Creating cli ...

这个配置文件中还有一个地方需要我们关注，那就是：base/docker-compose-base.yaml，我们接着看看当前目录下的base文件夹里的docker-compose-base.yaml文件。

这个配置文件就比较明显了，Orderer和peer的配置文件，细心的你肯定也发现了file: peer-base.yaml，那就看看同目录下的peer-base.yaml文件吧。

这我就不多解释了。
最后还有一个文件，在刚才的docker-compose-cli.yaml文件中有一句`command: /bin/bash -c './scripts/script.sh ${CHANNEL_NAME}; sleep $TIMEOUT'什么意思呢？就是./scripts/script.sh这个shell脚本生效，一起去看看吧。

我觉得终于到了你最希望看得的地方了，对于初学者而言的我们，看到good的时候就会心情很好，对吧？前面都为我们准备好了各节点，创世块，证书等内容！在这里这个文件为我们创建通道并且让各peer节点加入通道，安装、初始化、query准备好的chaincode！下图就是大致过程。

文件夹下还有许多的其他配置文件，其中如图。

下面用一张图总结一下：

大致过程基本如上，但感觉还差了一点什么！批评指正，批评指正！
