最终环境说明：ubuntu环境、新建并进入名为fabric的用户，Composer和blockchain explorer都被安装到了fabric用户的~目录
一、前置条件
1. 已安装Hyperledger Fabric
2. 已安装Hyperledger Composer
3. 已安装nodejs 8.11.x (Note that v9.x is not yet supported)（如果安装了Fabric，一般该项已安装）
4. 已安装docker 17.06.2-ce（如果安装了Fabric，一般该项已安装）
5. 已安装docker-compose 1.14.0（如果安装了Fabric，一般该项已安装）
6. 已安装PostgreSQL 9.5 or greater
如果没有安装PostgreSQL，则可按照以下教程按照
// 安装PostgreSQL
sudo apt update
sudo apt-get install postgresql-9.5教程https://blog.csdn.net/u013719339/article/details/84134586
二、下载blockchain explorer代码并切换到3.5.1版本
进入到fabric用户的~目录，无论是git下载，还是压缩包解压，本文都放到了fabric用户的~目录。
1. git方式下载
git clone https://github.com/hyperledger/blockchain-explorer.git
git checkout -b release-3.5.1 origin/release-3.5.1
2. 源代码压缩包下载
https://github.com/hyperledger/blockchain-explorer/tags?after=v0.3.7.1
完成下载之后，目录结构为
下载后解压的blockchain explore文件夹要给予权限
cd blockchain-explorer-0.3.5.1
chmod -R 775 ./*三、初始化数据库
1. 设置数据库连接信息
cd blockchain-explorer-0.3.5.1
cd blockchain-explorer-0.3.5.1/app/persistence/postgreSQL/db更改pgconfig.json文件，可以自己定义，后续脚本会生成对应用户
"pg": {
"host": "127.0.0.1",
"port": "5432",
"database": "fabricexplorer",
"username": "hppoc",
"passwd": "password"
}2.创建数据库并连接数据库
// 更改当前文件夹脚本权限
chmod -R 775 ./*
// 创建数据库 （创建数据库只用执行这一步，很多教程是执行了很多步，效果一样）
./createdb.sh
// 连接数据库
sudo -u postgres psql四、保持状态
1. 按照上面步骤，postgres数据库处于连接状态
2. 启动HyperLedger Composer
可以通过浏览器进入http://localhost:3000到playground验证是否启动成功
五、修改blockchain explore连接fabric的配置文件
cd blockchain-explorer-0.3.5.1/app/platform/fabric/config.json1. 配置文件中需要的信息来自《Hyperledger Composer 查看Fabric网络连接配置信息》https://blog.csdn.net/u013288190/article/details/104318276
2. 如果连接的是非TLS的peer节点（TLS也可以理解为https还是http的意思)，则需要修改peer的URL协议(grpcs->grpc)和端口(9051->9050)，然后删除tls_cacerts。根据这个值，应用程序决定是采用TLS或者非TLS录像访问hyperledger网络。
3. 下面贴出一份本文完整的配置文件以作参考

cd blockchain-explorer-0.3.5.1
npm install
cd blockchain-explorer-0.3.5.1/app/test
npm install
npm run test
cd blockchain-explorer-0.3.5.1/client/
npm install
npm test -- -u --coverage
npm run build以上没有错误证明搭建完成
七、运行 Hyperledger Explorer
cd blockchain-explorer-0.3.5.1/
// 开启后台执行
./start.sh
// http://localhost:8080 查看结果.
//关闭
./stop.sh
效果
