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
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：

配置各节点的信息及tls的ca证书，管理员的私钥及证书等信息。
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
#安装包
npm install
#运行测试脚本
npm run test
3、进入client/ 使用npm install 命令安装包
npm install
npm test -- -u --coverage
npm run build
8.4、启动fabric浏览器
使用脚本./start.sh来启动项目，启动成功后，可以打开浏览器查看一下.
浏览器截图
其中做了一些汉化。
