錯誤：
執行make docker遇到：core/chaincode/shim/java/javabuild.sh: line 51: gradle: command not found

解決辦法：刪除openjdk
安裝：oracle jdk1.8

手動gradle,註釋掉core/chaincode/shim/java/javabuild.sh裡面的gradle命令

啟動 ./network_setup.sh up

錯誤：2017-09-12 14:17:49.952 UTC [grpc] Printf -> DEBU 003 grpc: addrConn.resetTransport failed to create client transport: connection error: desc = "transport: Error while dialing dial tcp 211.139.178.49:7050: i/o timeout"; Reconnecting to {orderer.example.com:7050 <nil>}

解決辦法：

修改宿主機hosts    /etc/hosts   ,在實際環境中，建議通過配置 DNS 而不是修改 /etc/hosts 檔案

127.0.0.1  orderer.example.com

修改 base/peer-base.yaml，新增 volumes：

volumes:

-/etc/hosts:/etc/hosts

解決辦法：

類似這樣的錯誤，是因為channel已經建立，命名衝突

解決辦法：移除docker，重新啟動。執行最後一個命令即可 
1）刪除一個容器 docker rm 
2）強制刪除一個容器 docker rm -f 
3）強制刪除全部容器 docker rm -f $(docker ps -aq)
