HyperLedger/Fabric区块连网络 死磕fabric

linux 查看版本

查看版本： cat /proc/version 
查看位数：getconf LONG_BIT

linux添加DNS配置，出现不能上网的时候需要提前设置

修改文件 /etc/resolvconf/resolv.conf.d/base

nameserver 8.8.8.8
nameserver 218.2.135.1

保存退出后 重启服务
systemctl restart systemd-resolved.service

linux系统实现远程登录，SSH,SFTP

ftp 服务 root 用户无法登陆：
sudo vi /etc/ssh/sshd_config
找到PermitRootLogin 一行，改为PermitRootLogin yes ，即允许root用户以任何认证方式登录
$ sudo service ssh restart

关闭防火墙

部署前小白提前关闭防火墙
1 关闭
sudo ufw disable 

2 查看防火墙状态 
sudo ufw status

将Ubuntu的源改为国内的源(以阿里源为例)

#首先进行配置文件的备份
cp /etc/apt/sources.list /etc/apt/sources.list.bak
#编辑配置文件
vim /etc/apt/sources.list
在配置文件中开头添加以下内容(阿里源)：
　　　　

# deb cdrom:[Ubuntu 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.1)]/ xenial main restricted

执行命令更新：
sudo apt-get update
sudo apt-get upgrade

安装C环境

apt-get install bison ed gawk gcc libc6-dev make

安装pip

ubuntu系统自带了python2.7 和python3.5，我们直接使用python3
检查是否安装：
pip3 -V
安装pip3：
apt-get install python-pip #可忽略
apt-get install python3-pip
升级到最新pip
pip install --upgrade pip #可忽略
pip3 install --upgrade pip
安装python工具包
pip3 install --upgrade setuptools #可忽略
apt install python3 python-dev python3-dev 
build-essential libssl-dev libffi-dev 
libxml2-dev libxslt1-dev zlib1g-dev 
python-pip

pip3 install pep517 # 可忽略

Docker安装

#1: 安装必要的一些系统工具
sudo apt-get update
sudo apt-get -y install apt-transport-https ca-certificates curl software-properties-common
#2:安装GPG证书：
curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -

#3:也可以直接这样安装： 
sudo apt install docker.io

#4安装完成后需要修改当前用户（root）权限：
sudo usermod -aG docker root

#注销并重新登录，然后添加阿里云的Docker Hub镜像：
#5 配置镜像加速器 

#sudo tee /etc/docker/daemon.json <<-'EOF' 
{ 
"registry-mirrors": ["https://9pvya26y.mirror.aliyuncs.com"] 
} 
EOF 
sudo systemctl daemon-reload 
sudo systemctl restart docker

docker-compose升级安装

#先卸载旧版本
pip uninstall docker-compose

#再安装指定版本： 
pip install docker-compose==1.12.0 
or
pip3 install docker-comose==1.12.0

#安装完成之后如果  docker-comose -v 
#如果没显示 则重启服务器重新查看即可
卸载失败：
 1.提示不存在

python -m pip uninstall docker-compose
2.提示没有gcc环境
error: command 'i686-linux-gnu-gcc' failed with exit status 1
解决：
apt install python3 python-dev python3-dev 
      build-essential libssl-dev libffi-dev 
      libxml2-dev libxslt1-dev zlib1g-dev 
      python-pip

python -m pip install --upgrade pip
python -m pip uninstall docker-compose

源码安装go1.11

下载地址：https://studygolang.com/dl

1.设置环境变量
vim /etc/profile 
增加如下内容：
export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin
export GOPATH=/usr/local/go_program
环境变量生效：
source /etc/profile

2.安装C环境
apt-get install bison ed gawk gcc libc6-dev make

3.解压文件go1.4
tar -zxvf go1.4.src.tar.gz
mv go  /root/go1.4
cd /root/go1.4/src
安装1.4编译器
CGO_ENABLED=0 ./make.bash

4.安装1.11
tar -zxvf go1.11.linux-386.tar.gz -C /usr/local/
cd /usr/local/go/src
./all.bash

 安装完毕如下:

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

sudo apt-get install libltdl-dev 

Fabric源码下载

修改postBuffer的默认值
git config --global http.postBuffer 524288000
进行修改后确认
git config --list

修改配置 vim /etc/profile
export GIT_TRACE_PACKET=1
export GIT_TRACE=1
export GIT_CURL_VERBOSE=1
生效命令：
source /etc/profile

建立对应的目录 Git命令下载源码：
mkdir -p ~/go/src/github.com/hyperledger 
cd ~/go/src/github.com/hyperledger 
注意：下载过程可能由于网络原因会失败，没有关系，重新下载即可，可能要多执行几次才会成功
git clone https://github.com/hyperledger/fabric.git

或者指定版本下载源码fabric：
git clone -b release-1.0 git://github.com/hyperledger/fabric.git

cd ~/go/src/github.com/hyperledger/fabric
#版本为1.0的分支
git branch -a
git checkout release-1.0

下载源码fabric-samples
git clone https://github.com/hyperledger/fabric-samples.git
cd ./fabric-samples
#版本为1.0的分支
git branch -a
git checkout release-1.0

 源码下载失败处理办法：

下载过程异常报错：
error: RPC failed; curl 18 transfer closed with outstanding read data remaining
修正方法：
修改postBuffer的默认值
git config --global http.postBuffer 524288000
进行修改后确认
git config --list

修改配置 vim /etc/profile
export GIT_TRACE_PACKET=1
export GIT_TRACE=1
export GIT_CURL_VERBOSE=1
生效命令：
source /etc/profile
修改后重新下载。

以上仍然下载失败的话，尝试浅下载：

git clone --depth=1 http://xxx.git

git fetch --unshallow

源码编译并启动第一个fabric网络

#首先进入fabric文件夹 
cd ~/go/src/github.com/hyperledger/fabric/
#编译源码
make release
#查看生成的文件
cd release/linux-amd64/bin

 

#如果文件夹内有如下文件的话说明编译成功
#configtxgen  configtxlator  cryptogen  discover  idemixgen  orderer  peer

#将生成的文件添加进环境变量
vim ~/.profile
#文件中最后添加以下内容
export PATH=$PATH:$GOPATH/src/github.com/hyperledger/fabric/release/linux-amd64/bin
#更新一下
source ~/.profile

下载所依赖的镜像

source download-dockerimages.sh -c x86_64-1.0.0 -f x86_64-1.0.0

完成上面的操作，就可以启动第一个fabric网络了。

启动网络

#进入first-network文件夹
cd ~/go/src/github.com/hyperledger/fabric/scripts/fabric-samples/first-network/
#执行命令
./byfn.sh -m up
开启成功入下图
#关闭网络
./byfn.sh -m dwon

执行过程:

第一次启动失败了

 

 上图问题出现后，上网找了一堆都没啥用，最后关闭防火墙后，过去了

1 关闭
sudo ufw disable 

报错：Chaincode instantiation on PEER2 on channel 'mychannel' failed !

解决：
pip uninstall docker-compose
再安装指定版本： 
pip install docker-compose==1.12.0 

错误：2017-09-12 14:17:49.952 UTC [grpc] Printf -> DEBU 003 grpc: addrConn.resetTransport failed to create client transport: connection error: desc = "transport: Error while dialing dial tcp 211.139.178.49:7050: i/o timeout"; Reconnecting to {orderer.example.com:7050 <nil>}

!!!!!!!!!!!!!!! Channel creation failed !!!!!!!!!!!!!!!!
================== ERROR !!! FAILED to execute End-2-End Scenario ==================

解决办法：

修改宿主机hosts    /etc/hosts   ,在实际环境中，建议通过配置 DNS 而不是修改 /etc/hosts 文件

127.0.0.1  orderer.example.com

前面错没有了，但是又有新的错误：

 在网上找两个解决办法：说是镜像版本不一致导致

先看看docker镜像

 参考：https://blog.csdn.net/qq_24889075/article/details/103363201

解决：
 #1关闭服务
 ./byfn.sh -m down
 #2.先记录不一致的id信息后，然后关闭 再删除latest镜像景象
 docker rmi abf8289799c3 3df3c03f7ce2 e642eef94cae 1a326828a41f b31292eb8166
 #3.将现有的1.4或者amd64-0.4.21的镜像，改tag为latest
 docker tag  hyperledger/fabric-ccenv:1.4 hyperledger/fabric-ccenv:latest
 docker tag  hyperledger/fabric-baseos:amd64-0.4.21 hyperledger/fabric-baseos:latest
 #4.有必要的话就重启docker
 systemctl daemon-reload
 systemctl restart docker
 #5../byfn.sh -m up

问题处理问题查找路径：

https://blog.csdn.net/iflow/article/details/77951610
执行一直报错，后来直接手动下载并制定版本并执行后成功了，yeah

所有问题处理完之后启动

./byfn.sh -m up

 YEAH.
