篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了blockchain-explorer搭建（Docker）相关的知识，希望对你有一定的参考价值。
搭建方式有两种，一种是基于docker容器，一种是用代码库。
使用docker进行部署感觉方便很多。
一、使用docker部署
1 准备条件：
- Docker
- Docker Compose
2 启动fabric网络
官方指导：Hyperledger Fabric official tutorial
这里默认你已经配置好了fabric测试网络。
3 配置文件
3.1 从仓库获取配置文件
我这里直接在test-network 文件夹下面建立explorer文件夹：
mkdir explorer
- 有三个配置文件：
可通过这三个命令获得，也可直接复制我粘贴的。
$ wget https://raw.githubusercontent.com/hyperledger/blockchain-explorer/master/examples/net1/config.json
$ wget https://raw.githubusercontent.com/hyperledger/blockchain-explorer/master/examples/net1/connection-profile/test-network.json -P connection-profile
$ wget https://raw.githubusercontent.com/hyperledger/blockchain-explorer/master/docker-compose.yaml

},

}
},
"organizations": {

},

{
"network-configs": {
"test-network": {
"name": "Test Network",
"profile": "./connection-profile/test-network.json"
}
},
"license": "Apache-2.0"
}
3.2 将整个crypto 和artifact文件夹从test-network拷贝到explorer文件夹下
cp -rf organizetions explorer
此时explorer目录结构为这样（因为我启动网络的时候使用了ca和couchdb，所以会多ca文件夹）：
3.3 修改docker-compose.yaml
networks:
mynetwork.com:
external:
name: net_test
...
services:
explorer.mynetwork.com:
...
volumes:
- ./config.json:/opt/explorer/app/platform/fabric/config.json
- ./connection-profile:/opt/explorer/app/platform/fabric/connection-profile
- ./organizations:/tmp/crypto
- walletstore:/opt/wallet
这里注意一点，一个小坑，如果你的网络默认是net_test，则不需要修改。
（查看docker网络命令：docker network ls）
因为我的默认为docker_test，所以这里跟这改一下。
如果explorer链接到fabric网络是通过bridge network(桥接模式)，在environment中，DISCOVERY_AS_LOCALHOST=false
如果在后面遇到了端口冲突，也将8080:8080改为8090:8080，或者其他的与其对应即可。
修改后的docker- compose.yaml文件
# SPDX-License-Identifier: Apache-2.0
version: '2.1'
volumes:
pgdata:
walletstore:
networks:
mynetwork.com:
external:
name: docker_test
services:
explorerdb.mynetwork.com:
image: hyperledger/explorer-db:latest
container_name: explorerdb.mynetwork.com
hostname: explorerdb.mynetwork.com
environment:
- DATABASE_DATABASE=fabricexplorer
- DATABASE_USERNAME=hppoc
- DATABASE_PASSWORD=password
healthcheck:
test: "pg_isready -h localhost -p 5432 -q -U postgres"
interval: 30s
timeout: 10s
retries: 5
volumes:
- pgdata:/var/lib/postgresql/data
networks:
- mynetwork.com
explorer.mynetwork.com:
image: hyperledger/explorer:latest
container_name: explorer.mynetwork.com
hostname: explorer.mynetwork.com
environment:
- DATABASE_HOST=explorerdb.mynetwork.com
- DATABASE_DATABASE=fabricexplorer
- DATABASE_USERNAME=hppoc
- DATABASE_PASSWD=password
- LOG_LEVEL_APP=debug
- LOG_LEVEL_DB=debug
- LOG_LEVEL_CONSOLE=info
- LOG_CONSOLE_STDOUT=true
- DISCOVERY_AS_LOCALHOST=false
volumes:
- ./config.json:/opt/explorer/app/platform/fabric/config.json
- ./connection-profile:/opt/explorer/app/platform/fabric/connection-profile
- ./organizations:/tmp/crypto
- walletstore:/opt/explorer/wallet
ports:
- 8090:8080
depends_on:
explorerdb.mynetwork.com:
condition: service_healthy
networks:
- mynetwork.com
3.4 修改connection profile
"organizations": {
"Org1MSP": {
"adminPrivateKey": {
"path": "/tmp/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp/keystore/priv_sk"
注意priv_sk的名字，记得修改为和你对应文件夹的名字一样。如果你也是使用的ca证书，则不需要修改，直接使用原配置文件即可。
3.5 修改config.json文件
记得修改为和你使用的网络名和文件名一致。
4 启动容器服务
docker-compose up -d
如果需要清除容器，则使用命令
docker-compose down
如果需要清除容器和本地挂载的数据
docker-compose down -v
5 访问使用explorer
在地址栏输入：http://localhost:8080/
如果你修改了本地与容器的映射端口，像我，映射为 8090:8080。则需要输入:http://localhost:8090/
输入账号密码，即可登录访问。账号密码在connection profile里面设置。
账号：exploreradmin
密码：exploreradminpw
