Hyperledger Fabric Explorer 安装配置

所需依赖以及安装

• 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 多机部署》已经部署好了 Fabric 网络，这里用 CLI 那台机器来部署 Hyperledger Explorer，所以有些依赖已经安装好了。

安装 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
##修改密码
sudo -u postgres
psql -c "ALTER USER postgres PASSWORD 'postgres';"

安装 jq

apt-get install jq
jq --version

代码配置

Clone 项目代码

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

配置数据库

修改 app/explorerconfig.json

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

给 db 目录设置权限

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

执行数据库脚本

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

配置 fabric 网络

这里的配置基于我们上一篇搭建的 fabric 网络，进入blockchain-explorer/app/platform/fabric目录做响应的修改
config.json:

        "orderer.example.com": {
            "url": "grpc://localhost:7050"
        }
    }
}

打包编译

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

启动&停止

直接在项目目录下执行启动脚本:

./start.sh debug #开启debug

通过加上 debug 参数可以在日志文件中查看启动过程中的错误，默认服务器启动端口为8080,通过浏览器可以直接 ip+端口访问

停止服务

./stop.sh

到此一个可以用于实际生产环境的多机 Hyperledger Fabric 区块链网络部署就完成了。
