Fabric多台服务器的部署(五)

8、Fabric 浏览器的部署

8.1 环境准备

1、nodejs安装，在第1节里已经说过node的安装，需要注意的是node版本应该是v9.x以下。
2、PostgreSQL的安装，浏览器会把监听到的数据存储在pg里，所以需要安装pg数据。
ubuntu使用直接安装

sudo apt updatesudo apt install postgresql postgresql-contrib

安装好后，可以使用cli查看一下

#切换客户sudo -i -u postgres#进入控制台psql#退出postgres=# \q

3、安装Jq，jq是一个轻量级且灵活的命令行JSON解决器，安装很简单，见官网https://stedolan.github.io/jq/download/

8.2、下载浏览器源码

? 在github上下载fabric 浏览器的源码， hyperledger/blockchain-explorer，把源码拉下来，根据自己的需要选择不用的版本，我目前使用的是1.1版本，所以我切换到对应的1.1分支上。

8.3、修改配置

8.3.1 配置postgresql数据库

? 进入 app/persistence/postgreSQL/db/文件夹，找到pgconfig.json配置文件，修改连接pg数据库的配置，默认配置为

{  "pg": {    "host": "127.0.0.1",    "port": "5432",    "database": "fabricexplorer",    "username": "hppoc",    "passwd": "password"  }}

修改支运行createdb.sh脚本文件，创立浏览器所需的数据库和表名。

8.3.2、配置启动abric浏览器文件

进入 blockchain-explorer/app/platform/fabric，找到对应的config.json文件，配置对应的fabric网络信息，包括节点的请求接口，及监听接口，不同浏览器版本这个配置文件不太一样，1.1版本的配置文件如下：

{  "network-config": {    "org1": {      "name": "peerOrg1",      "mspid": "Org1MSP",      "peer1": {        "requests": "grpcs://localhost:7051",        "events": "grpcs://localhost:7053",        "server-hostname": "peer0.org1.mbasechain.com",        "tls_cacerts": "/Users/xuyao/Workspaces/trace_kingland/artifacts/channel/crypto-config/peerOrganizations/org1.mbasechain.com/peers/peer0.org1.mbasechain.com/tls/ca.crt"      },      "admin": {        "key": "/Users/xuyao/Workspaces/trace_kingland/artifacts/channel/crypto-config/peerOrganizations/org1.mbasechain.com/users/Admin@org1.mbasechain.com/msp/keystore",        "cert": "/Users/xuyao/Workspaces/trace_kingland/artifacts/channel/crypto-config/peerOrganizations/org1.mbasechain.com/users/Admin@org1.mbasechain.com/msp/signcerts"      }    },    "org2": {      "name": "peerOrg2",      "mspid": "Org2MSP",      "peer1": {        "requests": "grpcs://localhost:7056",        "events": "grpcs://localhost:7058",        "server-hostname": "peer0.org2.mbasechain.com",        "tls_cacerts": "/Users/xuyao/Workspaces/trace_kingland/artifacts/channel/crypto-config/peerOrganizations/org2.mbasechain.com/peers/peer0.org2.mbasechain.com/tls/ca.crt"      },      "admin": {        "key": "/Users/xuyao/Workspaces/trace_kingland/artifacts/channel/crypto-config/peerOrganizations/org2.mbasechain.com/users/Admin@org2.mbasechain.com/msp/keystore",        "cert": "/Users/xuyao/Workspaces/trace_kingland/artifacts/channel/crypto-config/peerOrganizations/org2.mbasechain.com/users/Admin@org2.mbasechain.com/msp/signcerts"      }    },    "org3": {      "name": "peerOrg3",      "mspid": "Org3MSP",      "peer1": {        "requests": "grpcs://localhost:8051",        "events": "grpcs://localhost:8053",        "server-hostname": "peer0.org3.mbasechain.com",        "tls_cacerts": "/Users/xuyao/Workspaces/trace_kingland/artifacts/channel/crypto-config/peerOrganizations/org3.mbasechain.com/peers/peer0.org3.mbasechain.com/tls/ca.crt"      },      "admin": {        "key": "/Users/xuyao/Workspaces/trace_kingland/artifacts/channel/crypto-config/peerOrganizations/org3.mbasechain.com/users/Admin@org3.mbasechain.com/msp/keystore",        "cert": "/Users/xuyao/Workspaces/trace_kingland/artifacts/channel/crypto-config/peerOrganizations/org3.mbasechain.com/users/Admin@org3.mbasechain.com/msp/signcerts"      }    },    "org4": {      "name": "peerOrg4",      "mspid": "Org4MSP",      "peer1": {        "requests": "grpcs://localhost:8056",        "events": "grpcs://localhost:9058",        "server-hostname": "peer0.org4.mbasechain.com",        "tls_cacerts": "/Users/xuyao/Workspaces/trace_kingland/artifacts/channel/crypto-config/peerOrganizations/org4.mbasechain.com/peers/peer0.org4.mbasechain.com/tls/ca.crt"      },      "admin": {        "key": "/Users/xuyao/Workspaces/trace_kingland/artifacts/channel/crypto-config/peerOrganizations/org4.mbasechain.com/users/Admin@org4.mbasechain.com/msp/keystore",        "cert": "/Users/xuyao/Workspaces/trace_kingland/artifacts/channel/crypto-config/peerOrganizations/org4.mbasechain.com/users/Admin@org4.mbasechain.com/msp/signcerts"      }    }  },  "channel": "mychannel",  "orderers":[    {      "mspid": "OrdererMSP",      "server-hostname":"orderer1.mbasechain.com",      "requests":"grpcs://localhost:7050",      "tls_cacerts":"/Users/xuyao/Workspaces/trace_kingland/artifacts/channel/crypto-config/ordererOrganizations/mbasechain.com/orderers/orderer1.mbasechain.com/tls/ca.crt"    },    {      "mspid": "OrdererMSP",      "server-hostname":"orderer2.mbasechain.com",      "requests":"grpcs://localhost:8050",      "tls_cacerts":"/Users/xuyao/Workspaces/trace_kingland/artifacts/channel/crypto-config/ordererOrganizations/mbasechain.com/orderers/orderer2.mbasechain.com/tls/ca.crt"    }  ],  "keyValueStore": "/tmp/fabric-client-kvs",  "configtxgenToolPath": "/Users/xuyao/Workspaces/goworkspace/src/blockchain/fabric/v1.2.0/fabric-samples/bin",  "SYNC_START_DATE_FORMAT":"YYYY/MM/DD",  "syncStartDate":"2018/01/01",  "eventWaitTime": "30000",  "license": "Apache-2.0",  "version": "1.1"}

配置各节点的信息及tls的ca证书，管理员的私钥及证书等信息。

8.3.3、构建node项目

1、进入blockchain-explorer/ 下，使用npm install 安装项目所需package，
2、再进入blockchain-explorer/app/test/下，使用npm install 安装测试项目里的所需包，再跑测试脚本

#安装包npm install#运行测试脚本npm run test

3、进入client/ 使用npm install 命令安装包

npm installnpm test -- -u --coveragenpm run build

8.4、启动fabric浏览器

? 使用脚本./start.sh来启动项目，启动成功后，可以打开浏览器查看一下.

浏览器截图

其中做了少量汉化。
