Unable to connect peer to channel in hyperledger fabric

I am following below link to setup my first network on Hyperledger Fabric http://hyperledger-fabric.readthedocs.io/en/latest/build_network.html

Whatever steps are mentioned in this setup i am pretty much able to do all. The issue is than when I try to join other peers to the channel, using below instruction

You can make other peers join the channel as necessary by making appropriate changes in the four environment variables.

I export following variables 

export CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[email protected]/msp
export CORE_PEER_ADDRESS=peer1.org1.example.com:8051
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer1.org1.example.com/tls/ca.crt

and then I run 

peer channel join -b mychannel.block

I get below error

This is problem of port.
Now how to decide which port to be given.

Check your configtx.yaml file.

 AnchorPeers:
            - Host: peer0.org2.example.com
              Port: 9052

Same port we need to pass below.

CORE_PEER_ADDRESS=peer0.org2.example.com:9052

Now run peer channel join -b mychannel.block

If still any issue you can mail me on [email protected]. Thanks

I think maybe the port's problem.

You set

export CORE_PEER_ADDRESS=peer1.org1.example.com:8051

While peer listen on 7051, therefore you need to change CORE_PEER_ADDRESS to

export CORE_PEER_ADDRESS=peer1.org1.example.com:7051.
