hyperledger fabric 测试（九）couch DB数据库设置

1安装CouchDB：docker pull klaemo/couchdb

创建文件夹：mkdir couchdb

启用一个CouchDB实例：docker run -p 5984:5984 -d --name my-couchdb -e COUCHDB_USER=admin -e COUCHDB_PASSWORD=password -v ~/couchdb:/opt/couchdb/data klaemo/couchdb

启动浏览器输入url：http://192.168.134.134:5984/_utils // 192.168.134.134是我自己的IP地址控制台输入ifconfig可查看

浏览器里输入账号admin 密码 password 进入数据库

2删除原来的CouchDB容器：docker rm -f my-couchdb

3新建4个CouchDB数据库：

cd ~

mkdir couchdb0

mkdir couchdb1

mkdir couchdb2

mkdir couchdb3

docker run -p 5984:5984 -d --name couchdb0 -e COUCHDB_USER=admin -e COUCHDB_PASSWORD=password -v ~/couchdb0:/opt/couchdb/data klaemo/couchdb

docker run -p 6984:5984 -d --name couchdb1 -e COUCHDB_USER=admin -e COUCHDB_PASSWORD=password -v ~/couchdb1:/opt/couchdb/data klaemo/couchdb

docker run -p 7984:5984 -d --name couchdb2 -e COUCHDB_USER=admin -e COUCHDB_PASSWORD=password -v ~/couchdb2:/opt/couchdb/data klaemo/couchdb

docker run -p 8984:5984 -d --name couchdb3 -e COUCHDB_USER=admin -e COUCHDB_PASSWORD=password -v ~/couchdb3:/opt/couchdb/data klaemo/couchdb

4更改docker-compose-cli.yam 编辑4个peer节点：

peer0.org1.example.com:

container_name: peer0.org1.example.com

environment:

- CORE_LEDGER_STATE_STATEDATABASE=CouchDB

- CORE_LEDGER_STATE_COUCHDBCONFIG_COUCHDBADDRESS=192.168.134.134:5984

- CORE_LEDGER_STATE_COUCHDBCONFIG_USERNAME=admin

- CORE_LEDGER_STATE_COUCHDBCONFIG_PASSWORD=password

extends:

file: base/docker-compose-base.yaml

service: peer0.org1.example.com

5启用Fabric：./network_setup.sh up

查看数据库信息：curl http://192.168.134.134:5984/mychannel_mycc/_all_docs //提示没有权限查看的话url输入账号密码

： curl http://admin:[email protected]:5984/mychannel_mycc/_all_docs

只查看a的信息：curl http://admin:[email protected]:5984/mychannel_mycc/a

进入容器：docker exec -it cli bash

运行链码测试marbles02：peer chaincode install -n marbles02 -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/marbles02

peer chaincode instantiate -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/cacerts/ca.example.com-cert.pem -C mychannel -n marbles02 -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/marbles02 -c '{"Args":["init"]}' -P "OR ('Org1MSP.member','Org2MSP.member')"

peer chaincode invoke -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/cacerts/ca.example.com-cert.pem -C mychannel -n marbles02 -c '{"Args":["initMarble","marble2","red","50","tom"]}'

peer chaincode query -C mychannel -n marbles02 -c '{"Args":["readMarble","marble2"]}'

curl http://192.168.134.134:5984/mychannel/marbles02%00marble2 //查询数据库的信息

curl -X PUT http://192.168.100.129:5984/mychannel/marbles02%00marble2 -d '{"_id":"marbles02\u0000marble2","_rev":"1-a1844f47b9ed94294b430c9a9a6f543b","chaincodeid":"marbles02","data":{"docType":"marble","name":"marble2","color":"green","size":10,"owner":"tom"},"version":"6:0"}' //更改其中的颜色信息为green 四个数据库都更改

再次调用查询查看颜色信息：

curl http://192.168.134.134:5984/mychannel/marbles02%00marble2

转帐后在查看颜色信息：peer chaincode invoke -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/cacerts/ca.example.com-cert.pem -C mychannel -n marbles02 -c '{"Args":["transferMarble","marble2","jerry"]}'

peer chaincode query -C mychannel -n marbles02 -c '{"Args":["readMarble","marble2"]}' //显示颜色为green 表示成功篡改fabric中的数据
