[Fabric]-First-Network(script.sh文件详解)
推荐fabric命令查询地址:看不懂可以直接查 fabric命令手册。
我理解的也没多好,新手上路,希望大家看到的可以指点一下。

二、utils.sh方法
1. 公用的信息
echo "先定义了orderer 和 3 个peer 的ca证书的位置"
ORDERER_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
PEER0_ORG1_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
PEER0_ORG2_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
PEER0_ORG3_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org3.example.com/peers/peer0.org3.example.com/tls/ca.crt
2. 检测
# verify the result of the end-to-end test
verifyResult() {
echo "verifyResult 创建e 2 e 使用"
if [ $1 -ne 0 ]; then
echo "!!!!!!!!!!!!!!! "$2" !!!!!!!!!!!!!!!!"
echo "========= ERROR !!! FAILED to execute End-2-End Scenario ==========="
echo
exit 1
fi
}
3. 设置OrdererOrg.Admin全局
# Set OrdererOrg.Admin globals
setOrdererGlobals() {
CORE_PEER_LOCALMSPID="OrdererMSP"
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/users/[email protected]/msp
}
4. 设置全局
setGlobals() {
PEER=$1
ORG=$2
if [ $ORG -eq 1 ]; then
# 定义peer 的msp 的位置 tls 啦
CORE_PEER_LOCALMSPID="Org1MSP"
CORE_PEER_TLS_ROOTCERT_FILE=$PEER0_ORG1_CA

5. 更新锚节点
updateAnchorPeers() {

echo "锚节点更新失败"
verifyResult $res "Anchor peer update failed"
echo "===================== Anchor peers updated for org '$CORE_PEER_LOCALMSPID' on channel '$CHANNEL_NAME' ===================== "

6. 加入通道
## Sometimes Join takes time hence RETRY at least 5 times
joinChannelWithRetry() {
PEER=$1
ORG=$2
# 调用设置全局
[setGlobals](https://www.wolai.com/sRSSQXgqioxU9LW72BYuxU#9TrZv7UFE2vBofkf4Q4Yma) $PEER $ORG
set -x

7. 安装链码
installChaincode() {

cat log.txt
verifyResult $res "Chaincode installation on peer${PEER}.org${ORG} has failed"
echo "===================== Chaincode is installed on peer${PEER}.org${ORG} ===================== "

8. 实例化链码
instantiateChaincode() {
PEER=$1

# while 'peer chaincode' command can get the orderer endpoint from the peer
# (if join was successful), let's supply it directly as we know it using

9. 升级链码
upgradeChaincode() {

10. 查询链码
