问题
Trying to achieve multicloud architecture between Azure and GCP. We have the orderer in a separate vm running in Azure. Now trying to join a peer which is running in another vm in google cloud platform. Our requirement is to join that peer to the channel in azure network. Inorder to join the peer to the channel, we tried fetching the genesis block from the orderer. But getting the following error:
peer channel fetch newest genesis.block -c composerchannelrest --orderer orderer0:7050 --tls --cafile /root/bcnetwork/conf/crypto-config/ordererOrganizations/ordererorg0/tlsca/tlsca.ordererorg0-cert.pem 2019-11-20 08:35:33.754 UTC [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized 2019-11-20 08:35:33.932 UTC [cli.common] readBlock -> INFO 002 Got status: &{FORBIDDEN} Error: can't read the block: &{FORBIDDEN}
Exported the env. variables as: export CHANNEL_NAME=composerchannelrest \
export CORE_PEER_ADDRESS=peer2:7051 \ export CORE_PEER_ID=Intainpeer2 \ export CORE_PEER_LOCALMSPID=Org0MSP \ export CORE_PEER_TLS_ENABLED=true \ export CORE_PEER_TLS_KEY_FILE=/root/bcnetwork/conf/crypto-config/peerOrganizations/org0/peers/peer2.org0/tls/server.key \ export CORE_PEER_TLS_CERT_FILE=/root/bcnetwork/conf/crypto-config/peerOrganizations/org0/peers/peer2.org0/tls/server.crt \ export CORE_PEER_TLS_ROOTCERT_FILE=/root/bcnetwork/conf/crypto-config/peerOrganizations/org0/peers/peer2.org0/tls/ca.crt \ export CORE_PEER_MSPCONFIGPATH=/root/bcnetwork/conf/crypto-config/peerOrganizations/org0/peers/peer2.org0/msp \ and FABRIC_CFG_PATH is under /root/bcnetwork/conf/crypto-config
Additional info: In the orderer vm, under /etc/hosts, we specified the internal IPs of peers(peers running in different VMs) and orderer. In the peer vm, under /etc/hosts, we specified the external IPs.
回答1:
From your log in the comments. What MSP ID is IntainOrg? You declare CORE_PEER_LOCALMSPID=Org0MSP, but it seems that your client's certificate (the one in $CORE_PEER_MSPCONFIGPATH/signcerts/cert.pem) belongs to a IntainOrg not recognised by your orderer, as probably Org0MSP or something similar is expected.
Maybe your organization of MSP ID Org0MSP has a MSP name IntainOrg, i don't know without your configtx.yaml (and I don't remember if the log shows the MSP ID or the MSP name), but the fact is that the orderer does not recognise the organization whose CA is signing your client's certificate.

# SECTION: Capabilities
#
# - This section defines the capabilities of fabric network. This is a new
# concept as of v1.1.0 and should not be utilized in mixed networks with
# v1.0.x peers and orderers. Capabilities define features which must be
# present in a fabric binary for that binary to safely participate in the
# fabric network. For instance, if a new MSP type is added, newer binaries
# might recognize and validate the signatures from this type, while older
# binaries without this support would be unable to validate those
# transactions. This could lead to different versions of the fabric binaries
# having different world states. Instead, defining a capability for a channel
# informs those binaries without this capability that they must cease
# processing transactions until they have been upgraded. For v1.0.x if any
# capabilities are defined (including a map with all capabilities turned off)
# then the v1.0.x peer will deliberately crash.
