安裝、部署超級賬本(hyperledger 2.2)遇到的坑
安裝部署是按照官方檔案的步驟進行的
官方檔案連接：https://hyperledger-fabric.readthedocs.io/zh_CN/release-2.2
以下列出我在安裝時遇到的問題及解決辦法
curl: (7) Failed to connect to xxx port 443: Connection refused
解決辦法：
（1）打開網站https://www.ipaddress.com/
搜索xxx，我這里演示的是Bit.ly，得到ip地址：67.199.248.10（選一個即可）
（2）替換系統的host檔案
這里由于是系統檔案需要復制一份出來修改，
把 67.199.248.10 bit.ly 放在檔案最后保存，最后再替換掉原本的，
（3）執行你要執行的命令就可以了

下載鏡像很慢或者總是不成功，可以配置鏡像加速器
這里推薦阿里鏡像加速器：https://cr.console.aliyun.com/cn-hangzhou/mirrors
進入網站后需要注冊登陸，搜索容器鏡像服務，點擊鏡像中心>>鏡像加速器
就可以看到如何配置的教程了， -
Error: chaincode install failed with status: 500 - failed to invoke backing implementation of 'InstallChaincode': chaincode already successfully installed
獲取已添加到通道分類賬中的汽車串列，在test-network目錄下執行
peer chaincode query -C mychannel -n fabcar -c '{"Args":["queryAllCars"]}'時，出現
Error: chaincode install failed with status: 500 - failed to invoke backing implementation of 'InstallChaincode': chaincode already successfully installed
解決辦法：查看報錯資訊，我們可以知道，鏈碼 fabcar 沒有在通道上被定義，所以我們進入對應目錄，執行啟動指令：cd /your path/fabric-samples/fabcar后，執行./startFabric.sh，等待完成即可，
最后再繼續運行之前的指令 peer chaincode query -C mychannel -n fabcar -c '{"Args":["queryAllCars"]}'，可以得到如下結果：
