基于helm一键部署fabric网络（五）jiang11958的专栏-一键部署fabric2

本教程是《Fabric实战教程之一步步走向生产》系列教程的第五篇，也是最为干货的一篇，直接一键部署fabric网络，动态支持LevelDB和CouchDB状态数据库，也支持三种排序模式：solo、kafka、etcdRaft，同时提供了一键生成connection-profile配置文件脚本以及blockchain-explorer区块链看板。

教程目录结构如下：

1. 简介
2. 基于docker部署最简fabric网络
3. 基于docker部署多机fabric网络
4. 一键部署k8s集群
5. 基于helm一键部署fabric网络
6. [国内网络下的网络搭建调整细节]
7. [踩坑总结]

本文教程在阿里云海外服务器上面实操，由于国内网络问题，docker和镜像都比较难下载，后面第六篇介绍国内网络下的脚本调整细节。

主机系统版本如下

[root@test ~]# cat /etc/redhat-release  CentOS Linux release 7.6.1810 (Core)  [root@test ~]# uname -a Linux test 3.10.0-957.21.3.el7.x86_64 #1 SMP Tue Jun 18 16:35:19 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux 

k8s网络拓扑如下：

下面启动脚本所实现的fabric网络拓扑如下:

1.启动k8s集群

参照上一章节快速启动k8s集群

2.启动网络（如下以上面的拓扑进行实现）

#以下所有命令都在k8s的master主机上进行操作 cd ~ git clone https://github.com/jiang11958/fabric-platform cd ~/fabric-platform sh run.sh "{'network':{'name':'fab'},'nfs':{'domain':'','in_ip':'172.21.28.224','ip':'172.21.28.224','port':22,'user':'root','pass':'password','path':'/nfs/fabric/fab','export':'172.21.28.0/24'},'orderer':{'name':'orderer','type':'etcdRaft','count':5,'port':'7050','domain':'orderer.example.com','password':'12345678','batchTimeout':'2','maxMessageCount':'10','absoluteMaxBytes':'99','preferredMaxBytes':'512'},'orgs':[{'name':'org1','mspName':'org1MSP','domain':'org1.example.com','stateDbType':'LevelDB','port':'7051','count':1},{'name':'org2','mspName':'org2MSP','domain':'org2.example.com','stateDbType':'LevelDB','port':'7051','count':1},{'name':'org3','mspName':'org3MSP','domain':'org3.example.com','stateDbType':'LevelDB','port':'7051','count':1}],'channels':[{'name':'mychannel2','orgs':['org1','org3']},{'name':'mychannel1','orgs':['org1','org2']}]}"

{  "network": {   "name": "fab"                      #fabric 网络名称  },  "nfs": {                               #nfs 配置   "domain": "",   "in_ip": "172.21.28.225",          #局域网 ip   "ip": "161.117.249.248",           #因特网 ip   "port": 22,                        #ssh 端口   "user": "root",                    #ssh 用户名   "pass": "password"                 #ssh 密码   "path": "/nfs/fabric/fab",        #nfs 共享路径   "export": "172.21.28.0/24"         #nfs 可访问的子网或ip列表  },  "orderer": {   "name": "orderer",                 #必须小写字母开头   "type": "etcdRaft",                #排序模式：solo kafka etcdRaft   "port": "7050",                    #orderer端口 默认   "count": 5,                        #排序模式下对应orderer节点数量solo:1 kafka:3 etcdRaft:5   "domain": "orderer.example.com",   #orderer 组织域名   "password": "12345678",            #MSP 证书密码   "batchTimeout": "2",               #orderer 默认设置   "maxMessageCount": "10",           #orderer 默认设置   "absoluteMaxBytes": "99",          #orderer 默认设置   "preferredMaxBytes": "512",        #orderer 默认设置  },  "orgs": [{                             #组织设置   "name": "org1",                    #必须小写字母开头   "mspName": "org1MSP",              #MSP ID   "domain": "org1.example.com",      #组织域名   "stateDbType": "LevelDB",          #状态数据库LevelDB 或者 CouchDB   "port": "7051",                    #peer 端口   "count": 1                         #peer 节点数量  }, {   "name": "org2",   "mspName": "org2MSP",   "domain": "org2.example.com",   "stateDbType": "LevelDB",             "port": "7051",   "count": 1  }, {   "name": "org3",   "mspName": "org3MSP",   "domain": "org3.example.com",   "stateDbType": "LevelDB",   "port": "7051",   "count": 1  }],  "channels": [{                         #通道配置   "name": "mychannel2",              #通道名称   "orgs": ["org1", "org3"]           #加入该通道的组织名  }, {   "name": "mychannel1",   "orgs": ["org1", "org2"]  }] } 

3.一键生产connection profile配置文件

#以下所有命令都在k8s的master主机上进行操作 cd ~/fabric-platform/profile sh run.sh "{"network":{"name":"fab"},"org":{"name":"org1","mspName":"org1MSP","domain":"org1.example.com","port":"7051"},"orderer":{"name":"orderer","count":"1","domain":"orderer.example.com"},"orgs":[{"name":"org1","mspName":"org1MSP","domain":"org1.example.com","port":"7051","count":"1"},{"name":"org2","mspName":"org2MSP","domain":"org2.example.com","port":"7051","count":"1"},{"name":"org3","mspName":"org3MSP","domain":"org3.example.com","port":"7051","count":"1"}],"channels":[{"name":"mychannel2","orgs":["org1","org3"]},{"name":"mychannel1","orgs":["org1","org2"]}]}"  

json格式说明

{  "network": {                           #fabric 网络名称   "name": "fab"  },  "org": {                               #此配置文件对应组织的信息   "name": "org1",   "mspName": "org1MSP",   "domain": "org1.example.com",   "port": "7051"  },  "orderer": {                           #orderer 组织配置   "name": "orderer",   "count": "5",                      #orderer节点数量 solo:1 kafka:3 etcdRaft:5   "domain": "orderer.example.com"  },  "orgs": [{                             #所有组织配置信息   "name": "org1",   "mspName": "org1MSP",   "domain": "org1.example.com",   "port": "7051",   "count": "1"  }, {   "name": "org2",   "mspName": "org2MSP",   "domain": "org2.example.com",   "port": "7051",   "count": "1"  }, {   "name": "org3",   "mspName": "org3MSP",   "domain": "org3.example.com",   "port": "7051",   "count": "1"  }],  "channels": [{                        #所有通道配置信息   "name": "mychannel2",   "orgs": ["org1", "org3"]  }, {   "name": "mychannel1",   "orgs": ["org1", "org2"]  }] } 

4.获取每个组织下的区块链看板地址

[root@test ~]cd ~ [root@test ~]kubectl get svc -n fab | grep explorer | awk '{split($5,port,/[:/]/); print $1 " " port[2]}' # get the explorer internet port #  explorer-org1 32320        ,组织org1 的explorer地址: https://your_master_ip:32320 #  explorer-org2 31224        ,组织org2 的explorer地址: https://your_master_ip:31224 #  explorer-org3 32101        ,组织org3 的explorer地址: https://your_master_ip:32101 

5.一键清除fabric网络

cd ~/fabric-platform sh remove.sh "{'network':{'name':'fab'}}"
