Hyperledger Fabric系列之四：2.2.1部署-执行peer命令-Centos7

1.设置环境变量：

export CORE_PEER_TLS_ENABLED=true
export PATH=/opt/workspace/gowork/hyperledger/fabric/scripts/fabric-samples/bin:$PATH
export FABRIC_CFG_PATH=/opt/workspace/gowork/hyperledger/fabric/scripts/fabric-samples/config/
export CORE_PEER_LOCALMSPID=Org1MSP
# export CORE_PEER_TLS_ROOTCERT_FILE=/opt/workspace/gowork/hyperledger/fabric/scripts/fabric-samples/test-network/organizations/peerOrganizations/org1.example.com/tls/ca.crt
export CORE_PEER_TLS_ROOTCERT_FILE=/opt/workspace/gowork/hyperledger/fabric/scripts/fabric-samples/test-network/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=/opt/workspace/gowork/hyperledger/fabric/scripts/fabric-samples/test-network/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
# export CORE_PEER_ADDRESS=org1.example.com:7051
export CORE_PEER_ADDRESS=localhost:7051

这里设置的环境变量是指向org1的peer节点。

1.1查看当前peer节点的通道列表

peer channel list 
--cafile <string> // TLS证书的绝对路径
--orderer <string> // 指定order节点 <hostname:port>
--tls // 使用TLS通信

1.2在当前节点创建通道：

peer channel create -c mychannel --orderer orderer.example.com:7050 -f \ ./createchannel.txn -t 30

1.3从order节点获取交易区块

peer channel fetch <newest|oldest|config|(block number)> [flags]
newest： 最新交易的块
oldest ：最早交易的块
config：最新的配置交易的块
block number：指定区块的号码

1.4加入通道

peer channel join 

需要指定通道配置区块

1.5查看指定通道区块链的令牌

peer channel getinfo

1.6对交易通道签名

peer channel signconfigtx 

1.7更新通道

peer channel update -c mychannel -f ./updatechannel.txn -o orderer.example.com:7050

2.碰到的问题及解决方案：

2.1执行peer命令报如下错：Error: error getting endorser client for channel: endorser client failed to connect to org1.example.com:7051: failed to create new connection: context deadline exceeded

环境变量缺失:

a.export CORE_PEER_TLS_ENABLED=true

b.环境变量配置错误：证书存放目录配置不正确。
