（Fabric学习八）部署区块链浏览器Hyperledger explorer
区块链浏览器Hyperledger explorer：
区块链浏览器：官方网站https://github.com/hyperledger-labs/blockchain-explorer
可以看到他需要以下几个文件 ：
- docker-compose.yaml
- test-network.json
- config.json
一、docker容器配置文件docker-compose-explorer.yaml
注意：如果从来没有设置过postgreSQL，那最好使用默认的账号hppoc和密码password，不然会报role '你自己的定义的账号' does not exist的错误导致explorer容器打开后秒挂，无法访问。
文件中要确保各项端口、IP对应，同时volumes中挂载的文件位置要正确。

我这里将网络配置文件取名为：org1ProdNetworkConnection.json
注意：这里adminCredential下面的id和password随你定，不必和上面的一样，之后访问浏览器使用的是这里的id和password
{
"name": "prod-network",
"version": "1.0.0",
"client": {
"tlsEnable": true,
"adminCredential": {
"id": "exploreradmin",
"password": "exploreradminpw"
},
"enableAuthentication": true,
"organization": "Org1",
"connection": {
"timeout": {
"peer": {
"endorser": "300"
},
"orderer": "300"
}
}
},
"channels": {
"businesschannel": {
"peers": {
"peer0.org1.example.com": {
"endorsingPeer": true,
"chaincodeQuery": true,
"ledgerQuery": true,
"eventSource": true
},
"peer1.org1.example.com": {
"endorsingPeer": true,
"chaincodeQuery": true,
"ledgerQuery": true,
"eventSource": true
},
"peer0.org2.example.com": {
"endorsingPeer": true,
"chaincodeQuery": true,
"ledgerQuery": true,
"eventSource": true
},
"peer1.org2.example.com": {
"endorsingPeer": true,
"chaincodeQuery": true,
"ledgerQuery": true,
"eventSource": true
}
}
}
},
"organizations": {
"Org1": {
"mspid": "Org1MSP",
"peers": [
"peer0.org1.example.com",
"peer1.org1.example.com"
],
"adminPrivateKey": {
"path": "/tmp/crypto/peerOrganizations/org1.example.com/users/User1@org1.example.com/msp/keystore/priv_sk"
},
"signedCert": {
"path": "/tmp/crypto/peerOrganizations/org1.example.com/users/User1@org1.example.com/msp/signcerts/User1@org1.example.com-cert.pem"
}
},
"Org2": {
"mspid": "Org2MSP",
"peers": [
"peer0.org2.example.com",
"peer1.org2.example.com"
],
"adminPrivateKey": {
"path": "/tmp/crypto/prod-network/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp/keystore/priv_sk"
},
"signedCert": {
"path": "/tmp/crypto/peerOrganizations/org2.example.com/users/User1@org2.example.com/msp/signcerts/User1@org2.example.com-cert.pem"
}
}
},
"peers": {
"peer0.org1.example.com": {
"url": "grpcs://peer0.org1.example.com:7051",
"grpcOptions": {
"ssl-target-name-override": "peer0.org1.example.com",
"hostnameOverride": "peer0.org1.example.com",
"request-timeout": 120001
},
"tlsCACerts": {
"path": "/tmp/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt"
}
},
"peer1.org1.example.com": {
"url": "grpcs://peer1.org1.example.com:8051",
"grpcOptions": {
"ssl-target-name-override": "peer1.org1.example.com",
"hostnameOverride": "peer1.org1.example.com",
"request-timeout": 120001
},
"tlsCACerts": {
"path": "/tmp/crypto/peerOrganizations/org1.example.com/peers/peer1.org1.example.com/tls/ca.crt"
}
},
"peer0.org2.example.com": {
"url": "grpcs://peer0.org2.example.com:9051",
"grpcOptions": {
"ssl-target-name-override": "peer0.org2.example.com",
"hostnameOverride": "peer0.org2.example.com",
"request-timeout": 120001
},
"tlsCACerts": {
"path": "/tmp/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt"
}
},
"peer1.org2.example.com": {
"url": "grpcs://peer1.org2.example.com:10051",
"grpcOptions": {
"ssl-target-name-override": "peer1.org2.example.com",
"hostnameOverride": "peer1.org2.example.com",
"request-timeout": 120001
},
"tlsCACerts": {
"path": "/tmp/crypto/peerOrganizations/org2.example.com/peers/peer1.org2.example.com/tls/ca.crt"
}
}
}
}三、编写配置文件config.tx
{
"network-configs": {
"prod-network": {
"name": "Prod Network",
"profile": "./connection-profile/org1ProdNetworkConnection.json"
}
},
"license": "Apache-2.0"
}
四、文件目录
文件准备好后，都要放在一个目录下，且保证目录的格式为：
./
├── config.json
├── connection-profile
│ └── org1ProdNetworkConnection.json
└── docker-compose-explorer.yaml五、启动容器
启动 Hyperledger Explorer：
docker-compose -f docker-compose-explorer.yaml up -d
清理（不删除持久性数据）：
docker-compose -f docker-compose-explorer.yaml down
彻底清理：
docker-compose -f docker-compose-explorer.yaml down -v
启动后访问 http://localhost:9090/:
这里的用户名和密码：要使用org1ProdNetworkConnection.json中的密码即可登录。
