1、docker安装Hyperledger explorer

步骤一、下载
git clone https://github.com/hyperledger/blockchain-explorer.git

步骤二、拷贝证书文件

拷贝fabric的crypto-config目录下的两个文件夹（ordererOrganizations、peerOrganizations）到blockchain-explorer/examples/net1/crypto 目录下

配置文件

步骤三、修改连接配置文件config.json

修改examples 目录下的config.json
配置文件

		"hello": {
			"name": "helloworld",
			"profile": "./connection-profile/hello.json"
		}
	},
	"license": "Apache-2.0"
}

其中profile为fabric连接文件。

步骤四、添加Fabric连接文件
将连接文件放到examples/net1/connection-profile目录下,连接文件hello.json的内容为：

		}
	}
}

***步骤五、修改docker-compose配置文件
通过docker启动explorer可以避免一些安装污染宿主机已有的环境，docker-compose.yaml主要包含了postgresql数据库和explorer工程node运行环境。

修改docker-compose.yaml docker服务配置文件
主要修改几个内容：

  • networks 改成与区块链同个网络便于访问区块链

  • 配置explorerdb.mynetwork.com
    添加端口和网络

    1
    2
    3
    4
    ports:
      - 5432:5432
    networks:
      - mynetwork.com

  • 配置explorer.mynetwork.com
    添加端口和网络

    1
    2
    3
    4
    ports:
        - 8090:8080
    networks:
        - mynetwork.com

整体配置文件如下：

2、运行docker-compose

在blockchain-explorer目录下执行

2

docker-compose up -d

如果出现错误一般情况下是Fabric连接文件或证书文件有错。

运行后在浏览器打开http://localhost:8090/,如下图所示：
