Hyperledger Fabric Explorer 安裝配置

所需依賴以及安裝

• Nodejs 8.11.x (Note that v9.x is not yet supported)
• PostgreSQL 9.5 or greater
• jq
• docker-ce
• docker-compose
• git
  在上一篇的《Hyperledger Fabric 多機部署》已經部署好了 Fabric 網絡，這裏用 CLI 那臺機器來部署 Hyperledger Explorer，因此有些依賴已經安裝好了。

安裝 PostgreSQL

sudo apt-get install wget ca-certificates
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main" >> /etc/apt/sources.list.d/pgdg.list'
sudo apt-get update
sudo apt-get install postgresql postgresql-contrib
##修改密碼
sudo -u postgres
psql -c "ALTER USER postgres PASSWORD 'postgres';"

安裝 jq

apt-get install jq
jq --version

代碼配置

Clone 項目代碼

git clone https://github.com/hyperledger/blockchain-explorer.git & cd blockchain-explorer

配置數據庫

修改 app/explorerconfig.json

{
    "persistence": "postgreSQL",
    "platforms": ["fabric"],
    "postgreSQL": {
        "host": "127.0.0.1",
        "port": "5432",
        "database": "fabricexplorer",
        "username": "postgres",
        "passwd": "postgres"
    }
}

給 db 目錄設置權限

chmod -R 775 app/persistence/fabric/postgreSQL/db

執行數據庫腳本

cd blockchain-explorer/app/persistence/fabric/postgreSQL/db
su - postgres
./createdb.sh

配置 fabric 網絡

這裏的配置基於咱們上一篇搭建的 fabric 網絡，進入blockchain-explorer/app/platform/fabric目錄作響應的修改
config.json:

        }
    }
}

打包編譯

apt-get install build-essential
cd blockchain-explorer
./main.sh install

啓動&中止

直接在項目目錄下執行啓動腳本:

./start.sh debug #開啓debug

經過加上 debug 參數能夠在日誌文件中查看啓動過程當中的錯誤，默認服務器啓動端口爲8080,經過瀏覽器能夠直接 ip+端口訪問

中止服務

./stop.sh

到此一個能夠用於實際生產環境的多機 Hyperledger Fabric 區塊鏈網絡部署就完成了。
