查看显卡

lspci | grep -i vga
  • 没有找到合适的显卡驱动

使用命令登录校园网

1
curl --data ./pwd  http://10.3.8.211/login
  • pwd用url-encoding编写以下内容
    1
    2
    user: '学号'

  • 在所有主机，fabric的docker中都配置一遍

fabric多机搭建

参考

  • docker compose文件中去掉其他机器的的volumes，peer，cli，orderer
  • 使用scp传送证书，*.block，打包好的链码等文件
1
scp fedfab.tar.gz tt@tt-HP:/home/tt/Desktop/fabric/my-network/nodes/mtemp

需要使用CouchDB

  • org1的service节点下增加

extra_hosts:
    - "orderer.fedfab.com:10.128.196.184"
    - "peer0.org1.fedfab.com:10.112.144.78"
    - "peer1.org1.fedfab.com:10.112.144.78"
    - "peer2.org1.fedfab.com:10.112.144.78"
    - "peer0.org2.fedfab.com:10.128.196.184"
  • fedml是否需要？

debug记录

调用chaincode失败

  • chaincode 的container启动时，与对应peer建立tcp连接失败
    • docker-compose的peer节点上，建立tcp的端口与实际端口的映射
