Fedora 25-64位操作系统中安装配置Hyperledger Fabric过程
安装过程参照Hyperledger Fabric的官方文档,文档地址:http://hyperledger-fabric.readthedocs.io/en/latest/prereqs.html
0x00 环境介绍,升级系统软件
搭建了一个vm,操作系统版本:
[root@fd240 ~]# cat /proc/version
Linux version 4.11.5-200.fc25.x86_64 (mockbuild@bkernel02.phx2.fedoraproject.org) (gcc version 6.3.1 20161221 (Red Hat 6.3.1-1) (GCC) ) #1 SMP Wed Jun 14 17:17:29 UTC 2017
搭建完毕,配置好网络后,升级系统软件:
[root@fd240 ~]# dnf update
0x01 安装依赖项
安装docker
此步骤参照官方文档:https://docs.docker.com/engine/installation/linux/fedora/#os-requirements
基本步骤如下:
添加docker的源:
$ sudo dnf config-manager \
--add-repo \
https://download.docker.com/linux/fedora/docker-ce.repo
更新dnf的包的索引:
sudo dnf makecache fast
安装:
sudo dnf install docker-ce
至少需要 Docker v1.12 以上版本。安装完之后检查版本号:
[root@fd240 ~]# docker -v
Docker version 17.03.1-ce, build c6d412e
然后安装docker-compose:
使用curl方式安装,安装过程中会出错,安装过程及解决办法参考我的这篇博客。
安装完毕后查看版本号:
[root@fd240 ~]# docker-compose version
docker-compose version 1.14.0-rc2, build 24dae73
docker-py version: 2.3.0
CPython version: 2.7.13
OpenSSL version: OpenSSL 1.0.1t 3 May 2016
安装go:
go的下载需要FQ,我安装的是这个版本:https://storage.googleapis.com/golang/go1.8.3.linux-amd64.tar.gz
下载完毕后,解压缩:
tar -C /usr/local -xzf go1.8.3.linux-amd64.tar.gz
解压缩完毕后,配置环境变量:
[root@fd240 ~]# vim /etc/profile
增加下列配置:
export PATH=$PATH:/usr/local/go/bin
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin
保存退出后,使之生效:
source /etc/profile
安装node.js,目前只支持 6.9.x版本的node.js, 但是7.x不支持。
我安装的是这个版本:https://nodejs.org/dist/v6.11.0/node-v6.11.0.tar.gz
从上面的官方下载地址下载巨慢,我依然选择了正确的上网姿势。
下载完毕后,解压缩:
tar -xJvf node-v6.11.0-linux-x64.tar.xz
我是放到$HOME 下的,因为我使用的是root用户,所以是在/root目录下。这不是个好习惯,所以操作的时候你一定要谨慎,因为正如Fedora所说”权力越大,责任就越大“。
cd node-v6.11.0-linux-x64/
然后创建软连接:
ln -s /root/node-v6.11.0-linux-x64/bin/node /usr/local/bin/node
ln -s /root/node-v6.11.0-linux-x64/bin/npm /usr/local/bin/npm
然后更新npm:
npm install npm@latest -g
查看已安装的node的版本:
[root@fd240 ~]# node -v
v6.11.0
0x02 安装Hyperledger Fabric
按照"搭建第一个网络"里的介绍来测试:
下面的这些步骤都需要你用正确的姿势上网, 我目前的搭配是: 安装ss的客户端,然后使用proxychains来代理shell, 安装proxychains的方法:http://www.tuicool.com/articles/rUNFF3
安装并设置完毕后, 运行:
proxychains4 bash
之后,你的本次shell会话中所有的连接都走了代理了.
好的,接下来继续:
迁出示例代码:
git clone https://github.com/hyperledger/fabric-samples.git
然后进入代码目录:
cd fabric-samples
然后下来安装二进制文件;
curl -sSL https://goo.gl/PabWJX | bash
这个时间是看你和你的服务器之间的速度了, 等待结束即可,一定得确保你是用正确的姿势上网的,不然这两步你都没办法成功.
我下载的已经是rc1版本的包了,前几天同时的还是alpha和beta,并且官方文档也在同步更改.
我本地库里下载好的镜像:

0x03 测试
先进入first-network目录:
cd first-network
看一下脚本使用说明:
./byfn.sh -h
如果您选择不提供频道名称,则脚本将使用默认的mychannel名称。 CLI超时参数(用-t标志指定)是可选值; 如果您选择不设置它,则CLI脚本结束后将退出CLI容器。
创建:
./byfn.sh -m generate
启动:
./byfn.sh -m up
默认是60秒后退出. 使用-t 参数可以指定时间,例如:
./byfn.sh -m up -t 864000
我这里在执行上面两条命令的时候都出现了一些警告信息.但是最终还是成功执行完毕了:
========= All GOOD, BYFN execution completed =========== _____ _ _ ____ | ____| | \ | | | _ \ | _| | \| | | | | | | |___ | |\ | | |_| | |_____| |_| \_| |____/
如果你想停止网络的话, 运行下面的命令即可,当然现在我们不停止,继续测试:
./byfn.sh -m down

进入节点的cli:
[root@fd240 first-network]# docker exec -it cli bash
root@33e3432d74b8:/opt/gopath/src/github.com/hyperledger/fabric/peer#
设置环境变量:
export CHANNEL_NAME=mychannel
byfn.sh中往这个 mychannel里初始化了两个变量,a和b, 默认值是90. 就类似执行了下列命令:
peer chaincode instantiate -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C $CHANNEL_NAME -n mycc -v 1.0 -c '{"Args":["init","a", "100", "b","200"]}' -P "OR ('Org1MSP.member','Org2MSP.member')"
下面我们执行一些操作:
查询:
peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","a"]}'
应该返回90
减10:
peer chaincode invoke -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C $CHANNEL_NAME -n mycc -c '{"Args":["invoke","a","b","10"]}'
应该返回200 OK
再查询:
peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","a"]}'
应该返回80
升级1.0.0之后遇到的问题:
在执行
./byfn.sh -m up
时,遇到一个错误提示:
[root@fedora26test first-network]# ./byfn.sh -m up Starting with channel 'mychannel' and CLI timeout of '10000' Continue (y/n)? y proceeding ... Starting peer1.org2.example.com ...

我尝试把所有文件及子文件夹的权限都改为777,重新尝试执行脚本依然报这个错误。于是就怀疑是否是SELinux的问题,打开Fedora的SELinux的错误报告程序,果然发现了,关掉SELinux,重启机器,OK。
