在上一篇创建通道中，创建通道最后一步是设置锚节点，是通过执行

docker exec cli ./scripts/setAnchorPeer.sh 1 mychannel 完成对组织org1中的锚节点设置，这里调用./scripts/setAnchorPeer.sh脚本文件，下面对将模拟脚本中的内容进行锚节点设置。

1. 前提条件

注释掉设置锚节点命令，关闭网络，重新开启网络并创建通道。

（1）注释设置锚节点命令

[root@localhost test-network-myself]# vi network-myself.sh

回车，按键盘上的 i 键或 Insert 功能键，进入编辑状态，注释设置锚节点，只显示如注释部分，内容如下：

	# 将org2节点加入通道
	peer channel join -b $BLOCKFILE
 
	# 设置组织org1的锚节点，docker exec命令中使用setAnchorPeer.sh脚本返回的信息作为参数部分
	#docker exec cli ./scripts/setAnchorPeer.sh 1 mychannel
 
	# 设置组织org2的锚节点，docker exec命令中使用setAnchorPeer.sh脚本返回的信息作为参数部分
	#docker exec cli ./scripts/setAnchorPeer.sh 2 mychannel

按ESC，输入:wq保存退出

（2）关闭网络

[root@localhost test-network-myself]# ./network-myself.sh down
关闭自己的测试网络

（4）创建通道

此时创建通道中没有设置锚节点

[root@localhost test-network-myself]# ./network-myself.sh createChannel

2. 设置org1中的锚节点

（1）进入client客户端

[root@localhost test-network-myself]# docker exec -it cli /bin/bash  #进入客户端
bash-5.1# ls  #查看客户端目录
organizations  scripts

（2）设置环境变量

bash-5.1# export ORG=1    #传递的参数
bash-5.1# export CHANNEL_NAME=mychannel   #传递的参数
bash-5.1# export CORE_PEER_TLS_ENABLED=true
bash-5.1# export ORDERER_CA=${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
bash-5.1# export PEER0_ORG1_CA=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
bash-5.1# export PEER0_ORG2_CA=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
bash-5.1# export PEER0_ORG3_CA=${PWD}/organizations/peerOrganizations/org3.example.com/peers/peer0.org3.example.com/tls/ca.crt
bash-5.1# export ORDERER_ADMIN_TLS_SIGN_CERT=${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/tls/server.crt
bash-5.1# export ORDERER_ADMIN_TLS_PRIVATE_KEY=${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/tls/server.key
bash-5.1# export CORE_PEER_LOCALMSPID="Org1MSP"
bash-5.1# export CORE_PEER_TLS_ROOTCERT_FILE=$PEER0_ORG1_CA
bash-5.1# export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
bash-5.1# export CORE_PEER_ADDRESS=localhost:7051
bash-5.1# export OUTPUT=${CORE_PEER_LOCALMSPID}config.json
bash-5.1# export HOST="peer0.org1.example.com"
bash-5.1# export PORT=7051

（3）获取通道配置

bash-5.1# peer channel fetch config config_block.pb -o orderer.example.com:7050 --ordererTLSHostnameOverride orderer.example.com -c mychannel --tls --cafile "$ORDERER_CA"
2021-11-22 10:57:38.039 UTC [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
2021-11-22 10:57:38.040 UTC [cli.common] readBlock -> INFO 002 Received block: 0
2021-11-22 10:57:38.041 UTC [channelCmd] fetch -> INFO 003 Retrieving last config block: 0
2021-11-22 10:57:38.041 UTC [cli.common] readBlock -> INFO 004 Received block: 0

由于最新的通道配置块是通道创世块，因此该通道的命令返回块0

（4）将配置块protobuf格式转成json格式

bash-5.1# configtxlator proto_decode --input config_block.pb --type common.Block | jq .data.data[0].payload.data.config >"${OUTPUT}"
bash-5.1# ls
Org1MSPconfig.json  config_block.pb     organizations       scripts

（5）将锚节点添加至配置文件中

bash-5.1# jq '.channel_group.groups.Application.groups.'${CORE_PEER_LOCALMSPID}'.values += {"AnchorPeers":{"mod_policy": "Admins","value":{"anchor_peers": [{"host": "'$HOST'","port": '$PORT'}]},"version": "0"}}' ${CORE_PEER_LOCALMSPID}config.json > ${CORE_PEER_LOCALMSPID}modified_config.json
bash-5.1# ls
Org1MSPconfig.json           organizations
Org1MSPmodified_config.json  scripts
config_block.pb

（6）设置环境变量

bash-5.1# export CHANNEL=mychannel
bash-5.1# export ORIGINAL=${CORE_PEER_LOCALMSPID}config.json
bash-5.1# export MODIFIED=${CORE_PEER_LOCALMSPID}modified_config.json
bash-5.1# export OUTPUT=${CORE_PEER_LOCALMSPID}anchors.tx

（7）将原始和修改的通道配置都转换回protobuf格式

并计算它们之间的差异

bash-5.1# configtxlator proto_encode --input "${ORIGINAL}" --type common.Config >original_config.pb
onfig.pb --updated modified_config.pb >config_update.pbbash-5.1# configtxlator proto_encode --input "${MODIFIED}" --type common.Config >modified_config.pb
bash-5.1# configtxlator compute_update --channel_id "${CHANNEL}" --original original_config.pb --updated modified_config.pb >config_update.pb
bash-5.1# ls
Org1MSPconfig.json           modified_config.pb
Org1MSPmodified_config.json  organizations
config_block.pb              original_config.pb
config_update.pb             scripts

（8）将配置更新包装在交易Envelope中

为了创建通道配置更新交易，将配置更新包装在交易Envelope中

bash-5.1# configtxlator proto_decode --input config_update.pb --type common.ConfigUpdate >config_update.json
bash-5.1# configtxlator proto_encode --input config_update_in_envelope.json --type common.Envelope >"${OUTPUT}"
configtxlator: error: open config_update_in_envelope.json: no such file or directory, try --help
bash-5.1# ls
Org1MSPanchors.tx            config_update.pb
Org1MSPconfig.json           modified_config.pb
Org1MSPmodified_config.json  organizations
config_block.pb              original_config.pb
config_update.json           scripts

（9）更新通道配置添加Peer 锚节点

bash-5.1# peer channel update -o orderer.example.com:7050 --ordererTLSHostnameOverride orderer.example.com -c $CHANNEL_NAME -f ${CORE_PEER_LOCALMSPID}anchors.tx --tls --cafile "$ORDERER_CA" >&log.txt

3. 设置org2中的锚节点

设置org2使用的环境变量，执行步骤与设置org1中的锚节点一样，此处不再赘述。

4. 将注释锚节点的命令解开

[root@localhost test-network-myself]# vi network-myself.sh

回车，按键盘上的 i 键或 Insert 功能键，进入编辑状态，注释设置锚节点，只显示如注释部分，内容如下：

	# 将org2节点加入通道
	peer channel join -b $BLOCKFILE
 
	# 设置组织org1的锚节点，docker exec命令中使用setAnchorPeer.sh脚本返回的信息作为参数部分
	docker exec cli ./scripts/setAnchorPeer.sh 1 mychannel
 
	# 设置组织org2的锚节点，docker exec命令中使用setAnchorPeer.sh脚本返回的信息作为参数部分
	docker exec cli ./scripts/setAnchorPeer.sh 2 mychannel

按ESC，输入:wq保存退出
