hyperledger fabric explorer 超级账本区块链浏览器搭建-使用docker的方式快速搭建一个超级账本区块链浏览器
-
区块链浏览器可以让用户更加直观地查看当前超级账本网络的情况，来观察整个区块链上的块数，节点数，通道，链码等；
-
官方推荐的搭建区块链浏览器有两种方法，一种是docker的方式，一种是用代码在自己本地的方式搭建，这里我们选择docker的方式搭建；
官方的github项目地址：
https://github.com/hyperledger/blockchain-explorer
Quick start (using Docker)
1、配置文件
# 新建文件夹，用于存放区块链浏览器搭建过程中的配置文件
mkdir explorer
cd explorer
# wget配置文件，由于被墙，可能无法直接获取
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
# 解决方法，手动创建配置文件，并通过访问下面网址，将配置文件内容复制进去
2、将区块链网络的证书文件整个目录复制到 explorer下，并重命名为organizations：
cd /root/block/geneg/twonodes/
cp -r crypto-config ../explorer/organizations
3、配置文件存放目录结构如下：
# 因为我们有两个peer节点，org1和org2
explorer
|___docker-compose.yaml
|___config.json
|___connection-profile
|___org1-network.json
|___org2-network.json
root@aa:~/block/geneg# cd /root/block/geneg/
root@aa:~/block/geneg# pwd
/root/block/geneg
root@aa:~/block/geneg# ls
twonodes
root@aa:~/block/geneg# mkdir explorer
root@aa:~/block/geneg# ls
explorer twonodes
root@aa:~/block/geneg# cd explorer
root@aa:~/block/geneg/explorer# mkdir connection-profile
root@aa:~/block/geneg/explorer# ls
connection-profile
