Hyperledger Explorer（区块链浏览器） 环境搭建
Hyperledger Explorer是一个简单，功能强大，易于使用，高度可维护的开源区块链浏览器，用于查看底层区块链网络上的活动。
软件安装
安装Node
下载tar包
解压
tar -xvf node-v12.16.2-linux-x64.tar.xz
mv node-v12.16.2-linux-x64 node-v12.16.2
配置全局使用
ln -s /usr/local/node-v12.16.2/bin/node /usr/local/bin/node
ln -s /usr/local/node-v12.16.2/bin/npm /usr/local/bin/npm
安装PostgreSQL
apt-get install postgresql
启动服务
/etc/init.d/postgresql start
修改用户密码：
su - postgres 切换用户，执行后提示符会变为 '-bash-4.2$'
psql -U postgres 登录数据库，执行后提示符变为 'postgres=#'
ALTER USER postgres WITH PASSWORD 'postgres'; 设置postgres用户密码为postgres
\q 退出数据库
exit 退出命令行界面
卸载
apt-get --purge remove postgresql*
apt-get --purge remove postgis*
安装jq
apt install jq
安装gcc
apt install gcc
gcc --version
Hyperledger Explorer下载
cd /opt/gopath/src/github.com/hyperledger
git clone https://github.com/hyperledger/blockchain-explorer.git
创建数据库
我们使用默认版本，进行数据库创建：
cd blockchain-explorer/app
vi explorerconfig.json
修改配置如下：
{
"persistence": "postgreSQL",
"platforms": ["fabric"],
"postgreSQL": {
"host": "127.0.0.1",
"port": "5432",
"database": "fabricexplorer",
"username": "postgres",
"passwd": "postgres"
},
"sync": {
"type": "local",
"platform": "fabric",
"blocksSyncTime": "1"
},
"jwt": {
"secret": "a secret phrase!!",
"expiresIn": "2h"
}
}
运行创建数据库的脚本
cd /opt/gopath/src/github.com/hyperledger/blockchain-explorer/app/persistence/fabric/postgreSQL/db
./createdb.sh
查看数据库状态指令：
sudo -u postgres psql -c '\l'
sudo -u postgres psql fabricexplorer -c '\d'
定义fabric网络连接参数
cd /opt/gopath/src/github.com/hyperledger/blockchain-explorer/app/platform/fabric/
vim config.json
设置enableAuthentication属性false，用于关闭登录认证
{
"network-configs": {
"first-network": {
"name": "firstnetwork",
"profile": "./connection-profile/first-network.json",
"enableAuthentication": false
}
},
"license": "Apache-2.0"
}
设置first-network.json配置
继续进行设置（Fabric网络环境要处于正常启动的状态，不然下述路径的文件是不存在的）
cd /opt/gopath/src/github.com/hyperledger/blockchainexplorer/app/platform/fabric/connection-profile/
vim first-network.json
重点设置如下几项：
{
"name": "first-network",
"version": "1.0.0",
"license": "Apache-2.0",
"client": {
"tlsEnable": true,
"caCredential": {
"id": "admin",

},
"enableAuthentication": true,
"organization": "Org1MSP",
"connection": {
"timeout": {
"peer": {
"endorser": "300"
},
"orderer": "300"
}
}
},
"channels": {
"zmeduchannel": {
"peers": {
"peer0.org1.example.com": {}
},
"connection": {
"timeout": {
"peer": {
"endorser": "6000",
"eventHub": "6000",
"eventReg": "6000"
}
}
}
}
},
"organizations": {
"Org1MSP": {
"mspid": "Org1MSP",
"adminPrivateKey": {
"path": "/opt/gopath/src/github.com/hyperledger/fabric/example/crypto-config/peerOrganizations/org1.example.com/users/[email protected]/msp/keystore/9ccc1d5b3baae6d7a0aa697d6cae8009ad55c12cbdba34cdaeaaf7ab15d96ab0_sk"
},
"peers": ["peer0.org1.example.com"],
"signedCert": {
"path": "/opt/gopath/src/github.com/hyperledger/fabric/example/crypto-config/peerOrganizations/org1.example.com/users/[email protected]/msp/signcerts/[email protected]"
}
}
},
"peers": {
"peer0.org1.example.com": {
"tlsCACerts": {
"path": "/opt/gopath/src/github.com/hyperledger/fabric/example/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt"
},
"url": "grpcs://peer0.org1.example.com:7051",
"grpcOptions": {
"ssl-target-name-override": "peer0.org1.example.com"
}
}
},
"certificateAuthorities": {
"ca0": {
"url": "https://peer0.org1.example.com:7054",
"httpOptions": {
"verify": false
},
"tlsCACerts": {
"path": "/opt/gopath/src/github.com/hyperledger/fabric/example/crypto-config/peerOrganizations/org1.example.com/ca/ca.org1.example.com-cert.pem"
},
"caName": "ca0"
}
}
}- adminCredential 设置浏览器登录的用户密码
- channels 设置通道名、peer0名
- organizations 设置证书路径
- peers 设置peer-ca证书路径
- certificateAuthorities 设置ca证书路径
注：需要说明一点，这两个 "tlsCACerts" 并不在一个字典中，配置时要特别注意，还有就是以自己的文件路径为主。
