fabric 1.4网络搭建以及fabric浏览器搭建

1. fabric网络搭建

环境准备

1. 一台空闲服务器,需要安装docker和go环境,安装步骤自行百度
2. 点击下载fabric-samples源代码
3. 将fabric-samples的分支切换到release-1.4,然后进行打包,上传到服务器上

安装fabric网络

生成配置文件

在服务器上对fabric-samples进行解压,并切换到fabric-samples/first-network目录下,执行命令./byfn.sh generate,控制台输入Y或者回车,即可完成配置文件生成,然后出现一堆信息,控制台找不到了,从官网截了个图

fabric_byfn.png

具体的步骤可以看byfn.sh中的内容

fabric_byfn_generate.png
主要是生成证书和替换密钥文件,最后一步是创建channelArtifacts
fabric_byfn_channelartifacts.png
看这命令是不是有点熟悉,其实就是你的控制台输出,默认CONSENSUS_TYPE是solo,主要就是创建锚节点然后更新transactions

启动网络

在fabric-samples/first-network目录下执行命令./byfn.sh up,控制台输入Y或者回车,就会出现如下的输出

fabric_docker_up.png
具体逻辑可以看byfn.sh,大概意思就是docker创建了几个容器,创建OrdererMSP,Org1MSP以及Org2MSP,然后创建节点和通道,然后让节点加入通道

是否安装完成的如下图

注意将first-network目录下的crypto-config目录进行打包,并下载到本地,区块链浏览器会进行使用

进行peer节点操作

查询启动的容器,我们可以看到有个cli的容器,它是可以操作peer节点的容器,我们只需要进入cli容器即可进行peer节点的操作

1. 进入cli容器
   docker exec -it cli bash
2. 进行操作
   点击查看peer命令,查看peer版本执行peer version
   fabric_peer_version.png
   查看peer的通道有哪些,执行 peer channel list
   fabric_peer_channel.png

2. fabric浏览器搭建

环境准备

点击下载fabric-explorer源代码,或者下载汉化版fabric-explorer-cn,记得阅读README.md文件

代码依赖安装和编译

进入下载目录,例如使用fabric-explorer-cn,则进入fabric-explorer-cn,然后执行命令./main.sh install,等待执行完成,时间较久,如果要清除node_modules的话,可以执行./main.sh clean

数据库配置文件修改

如果进行数据库地址修改的话,可以编辑app/explorerconfig.json文件,修改postgreSQL字段下的host等信息,注意你的pg数据库要有对应的账户和schema,然后进入app/persistence/fabric/postgreSQL/db/explorerpg.sql,将脚本进行整理,并在数据库执行,文末提供sql内容,或者是使用README.md推荐的在本地执行./createdb.sh进行pg创建

区块链浏览器配置文件修改

编辑根目录下的appconfig.json文件,如果需要别人访问你的浏览器的话,就将host改为自己的ip地址,如果端口冲突的话,就修改port

fabric客户端配置

在app/platform/fabric/config.json文件中,可以看到引用的profile为./connection-profile/first-network.json,打开同目录的connection-profile/first-network.json文件,进行修改,看到有很多参数,其实里面很多我们都可以不用管,只需要修改证书文件路径,还记得上面说让下载的crypto-config目录到本地吗,将如下几个地方修改成自己的路径即可

注意path要全部换掉,因为有可能adminPrivateKey的path最后生成的sk文件的hash不一样

配置hosts域名映射

在自己的hosts文件中,新增两个域名映射,即orderer.example.com和peer0.org1.example.com都映射到自己的服务器ip上

blockchain_explorer_hosts.png

配置启动脚本

编写根目录下的start.sh和syncstart.sh文件,将他们的export DISCOVERY_AS_LOCALHOST=true,改成export DISCOVERY_AS_LOCALHOST=false,当然如果你的fabric网络运行在你本机的话,就使用默认的即可

启动区块链浏览器

打开控制台,执行./start.sh,logs/app/app.log是查看应用日志,logs/console/console.log是查看控制台的,logs/db/db.log是查看数据库日志

访问区块链浏览器

打开浏览器,输入localhost:8080,或者是你在appconfig.json文件中配置的host:port进行访问,输入用户名admin以及密码adminpw,点击登录即可进入区块链浏览器主页
