Hyperledger Fabric 1.0 Environment Construction Practice - Continuously updated...

After multiple machines are deployed, the intranet IPs are 10.18.22.221, 10.18.22.222, 10.18.22.223, 10.18.22.224, 10.18.22.225.

Among them, 10.18.22.221 is the orderer node, and the other 4 are peer nodes.

The domain names are orderer.com, peer0.org1.com, peer1.org1.com, peer0.org2.com, peer1.org2.com.

Among them, chaincode is installed on peer0.org1.com, peer0.org2.com, peer1.org2.com by default, and chaincode is not installed on peer1.org1.

After successfully starting the cluster,

1. The process of installing the smart contract chainCode on 10.18.22.223 (peer1.org1.example.com) is as follows:

1. Enter the container of 10.18.22.223 (peer1.org1.example.com) through the following command

docker exec -it cli bash

After entering the container, the default path is as follows:

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

2. Execute the smart contract ChainCode installation command

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

After the command is executed, the log process is as follows:

2018-03-26 02:44:30.379 UTC [chaincodeCmd] install -> DEBU 00d Installed remotely response:<status:200 payload:"OK" > 

It means that the Chaincode has been installed successfully. This command installs the source code of chaincode into the file system of the peer.

3. Call the command to query the Chaincode

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

After calling this command, the smart contract container will be started. After waiting for a while, the query result will be obtained.

root@6e75c97a960a:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'

4. Create a new command window and query through docker-ps to find the newly installed chaincode container.

[root@localhost ~]# docker ps
