多机部署后内网IP分别为10.18.22.221,10.18.22.222,10.18.22.223,10.18.22.224,10.18.22.225.

十余年的城口网站建设经验，针对设计、前端、开发、售后、文案、推广等六对一服务，响应快，48小时及时工作处理。营销型网站的优势是能够根据用户设备显示端的尺寸不同，自动调整城口建站的显示方式，使网站能够适用不同显示终端，在浏览器中调整网站的宽度，无论在任何一种浏览器上浏览网站，都能展现优雅布局与设计，从而大程度地提升浏览体验。创新互联从事“城口网站设计”,“城口网站推广”以来，每个客户项目都认真落实执行。

其中10.18.22.221为orderer节点，其余4个为peer节点。

域名分别为orderer.com，peer0.org1.com,peer1.org1.com,peer0.org2.com,peer1.org2.com.

其中默认在peer0.org1.com,peer0.org2.com,peer1.org2.com上安装了chaincode，在peer1.org1上未安装chaincode。

成功启动集群后，

一、在10.18.22.223（peer1.org1.example.com）上安装智能合约chainCode过程如下：

1、通过下面命令进入10.18.22.223（peer1.org1.example.com）的容器

docker exec -it cli bash

进入容器后，默认路径如下：

root@6e75c97a960a:/opt/gopath/src/github.com/hyperledger/fabric/peer#

2、执行智能合约ChainCode安装命令

peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02

命令执行后，日志过程如下：

说明该Chaincode已经安装成功。这个命令将chaincode的源码安装到该peer节点的文件系统中。

3、调用命令查询Chaincode

peer chaincode query -C $CHANNEL_NAME -n mycc -c \'{"Args":["query","a"]}\'

调用该命令后，将会启动智能合约容器。等待一段时间，将得到查询结果。

root@6e75c97a960a:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode query -C mychannel -n mycc -c \'{"Args":["query","a"]}\' 2018-03-26 02:58:50.594 UTC [msp] GetLocalMSP -> DEBU 001 Returning existing local MSP 2018-03-26 02:58:50.594 UTC [msp] GetDefaultSigningIdentity -> DEBU 002 Obtaining default signing identity 2018-03-26 02:58:50.594 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 003 Using default escc 2018-03-26 02:58:50.595 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 004 Using default vscc 2018-03-26 02:58:50.595 UTC [msp/identity] Sign -> DEBU 005 Sign: plaintext: 0A95070A6708031A0C08EAC3E1D50510...6D7963631A0A0A0571756572790A0161 2018-03-26 02:58:50.595 UTC [msp/identity] Sign -> DEBU 006 Sign: digest: B4B927D16A7B0B16747B264E0336F79769F5F841F67B1C70C2B75431ACD1E168 Query Result: 90 2018-03-26 02:58:50.618 UTC [main] main -> INFO 007 Exiting.....

4、新建一个命令窗口，通过docker-ps 查询，已经能够查到，新安装的链码容器。
