hyperledger blockchain-explorer区块浏览器安装

本版本是Ubuntu16.04 在安装完fabric并运行的情况下再安装

1.升级node、npm

1.产看node版本，没安装的请先安装；

 $  node -v

2.清楚node缓存；

$  sudo npm cache clean -f  

3.安装node版本管理工具'n';

$  sudo npm install n -g

4.使用版本管理工具安装指定node或者升级到最新node版本；

$  sudo n stable  （安装node最新版本）

$  sudo n 8.9.4 （安装node指定版本8.9.4）

安装完成后再查看自己安装的版本
node-v
npm -v 

2 安装jq和postgresql

1.安装jq
 $ sudo apt install jq

2.安装postgresql
$ sudo apt install postgresql

(可选)
$ 1.sudo passwd -d postgres //以前密码作废
$ 2.sudo -u postgres passwd //设置新的密码 

3下载blockchain-explorer文件

1.更新配置信息
在sudo vim blockchain-explorer/app/platform/fabric/config.json修改

{
    "network-configs": {
        "first-network": {
            "name": "firstnetwork",
            "profile": "./connection-profile/first-network.json", //添加逗号
            "enableAuthentication": false //添加此条命令
        }
    },
    "license": "Apache-2.0"
}

2.更新组织证书信息
sudo vim blockchain-explorer/app/platform/fabric/connection-profile/first-network.json

organizations": {
                "Org1MSP": {
                        "mspid": "Org1MSP",
                        "fullpath": true,
                        "adminPrivateKey": {
                        //该参数除了更改路径外，还需要将_sk文件名改为你的相应路径下对应文件的真实文件名
                                "path": "/root/go/src/github.com/hyperledger/fabric-samples/first-network/crypto-config/peerOrganizations/org1.example.com/users/[email protected]/msp/keystore/8e23e246ec217c202df57e4525d9d9d30099067df634e666e2c6718548d33f71_sk"
                        },
                        //将"fabric-path"改为你的对应的绝对路径
                        "signedCert": {
                                "path": "/root/go/src/github.com/hyperledger/fabric-samples/first-network/crypto-config/peerOrganizations/org1.example.com/users/[email protected]/msp/signcerts/[email protected]"
                        }
                }
        },
        "peers": {
                "peer0.org1.example.com": {
                        "tlsCACerts": {
                         //将"fabric-path"改为你的对应的绝对路径
                                "path": "/root/go/src/github.com/hyperledger/fabric-samples/first-network/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt"
                        },
                        "url": "grpcs://localhost:7051",
                        "eventUrl": "grpcs://localhost:7053",
                        "grpcOptions": {
                                "ssl-target-name-override": "peer0.org1.example.com"
                        }
                }
//下面还有一个要修改路径，总共三个

4.创建数据库脚本

$cd blockchain-explorer/app/persistence/fabric/postgreSQL/db
$sudo ./createdb.sh

注意：要先给db权限 sudo chmod -R 775 db/

查看数据

$ sudo -u postgres psql -c '\l'
                                List of databases
      Name      |  Owner   | Encoding | Collate |  Ctype  |   Access privileges

                |          |          |         |         | postgres=CTc/postgres

                |          |          |         |         | postgres=CTc/postgres
(4 rows)

  //按住q退出

$ sudo -u postgres psql fabricexplorer -c '\d'
                   List of relations

5. 安装依赖

有两种方式
第一种
//进入到blockchain-explorer
$ ./main.sh install    //安装测试创建文件
 
$ ./main.sh clean  //清理文件夹  （这条命令重启的时候用）
To clean the /node_modules, client/node_modules client/build, client/coverage, app/test/node_modules directories

第二种
$ cd blockchain-explorer
$ npm install
$ cd client/
$ npm install
$ npm run build

6 启动项目

//进入到blockchain-explorer目录
$sudo ./start.sh

然后再页面输入http://localhost:8080
