Fabric多台服务器的部署(五)

| Comments

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

1
2

sudo apt update
sudo apt install postgresql postgresql-contrib

安装好后，可以使用cli查看一下

#切换用户
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处理器，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，https://github.com/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，创建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：

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
