博主最近在搭建Hyperledger Fabric区块链浏览器过程中也学习了很多博主的搭建流程，踩了很多雷，踩了很多
坑，现将成功搭建好的Hyperledger Fabric区块链浏览器详细流程分享如下，帮助大家避雷闭坑
fabric浏览器
Hyperledger Explorer 是一个简单，强大，易于使用，维护良好的开源实用程序，可浏览底层区块链网络上的活
动。用户可以在MacOS和Ubuntu上配置和构建Hyperledger Explorer。先要保证你之前项目已成功启动。
搭建Hyperledger Fabric区块链浏览器前提
1. 成功搭建部署好Hyperledger Fabric 2.4（2.x）网络
搭建目录结构
在 hyperledger 目录下 新建同级目录 explorer
然后进入 test-network 目录下启动网络
启动Fabric网络
./network.sh up createChannel -ca -s couchdb
将启动成功网络后生成的证书文件夹 organizations 复制到前面新建的 explorer 文件夹中
然后下载如下如下三个配置文件（官方推荐） 但是因为网络原因很难下载下来
docker-compose.yaml
config.json
test-network.json
wget https://raw.githubusercontent.com/hyperledger/blockchain-explorer/main/examples/net1/config.json
wget https://raw.githubusercontent.com/hyperledger/blockchain-explorer/main/examples/net1/connection-profile/test-network.json -P connection-profile
wget https://raw.githubusercontent.com/hyperledger/blockchain-explorer/main/docker-compose.yaml
所以推荐大家先把官方的区块链项目下载下来，然后将需要的三个配置文件放进 explorer 文件夹中
官方区块链浏览器项目地址 https://github.com/hyperledger-labs/blockchain-explorer
这里需要将 test-network.json 文件 放在 connection-profile 目录下，其它均在 explorer 目录中的同级目录下
至此启动区块链浏览器需要的完整目录结构如下：
docker-compose.yaml
config.json
connection-profile/test-network.json
organizations/ordererOrganizations/
organizations/peerOrganizations/
虚拟机中的目录结构图如下：
修改三个配置文件
找到docker网络
docker network ls
我们可以看到 本区块链浏览器的docker网络为 fabric_test 后面在修改配置文件的时候需要修改

启动浏览器
依次执行如下命令
假如之前启动过 先停用镜像
sudo docker-compose down
在 docker-compose.yaml 中为持久性数据（Postgres 数据和用户钱包）分配了两个命名卷。如果要清除这些命名卷
sudo docker-compose down -v
一定要设置好下面三个环境变量，不然启动浏览器会报错！！！！！！！
export EXPLORER_CONFIG_FILE_PATH=./config.json
export EXPLORER_PROFILE_DIR_PATH=./connection-profile
export FABRIC_CRYPTO_PATH=./organizations
最后启动区块链浏览器
sudo docker-compose up -d
打开浏览器输入
http://127.0.0.1:8080
成功启动浏览器
默认登录名、密码如下
"id": exploreradmin
"password": exploreradminpw
也可以在 test-network.json 文件中修改登录名和密码
"adminCredential": {
},
出现如下界面表示启动成功
登录进入后可以看到fabric 浏览器详细信息：区块信息、通道信息、节点信息等等
