Hyperledger Fabric部署的坑(更新中)

1.映象需與fabric版本一致

fabric執行所需要的映象一共是12種

可以通過輸入docker images檢視你已下載的映象。

如果發現有少的映象則用下述語句下載，每條語句對應下載每一個映象，請根據所缺失的映象選擇語句並執行：

docker pull hyperledger/fabric-tools:x86_64-1.0.0
docker pull hyperledger/fabric-couchdb:x86_64-1.0.0
docker pull hyperledger/fabric-kafka:x86_64-1.0.0
docker pull hyperledger/fabric-orderer:x86_64-1.0.0
docker pull hyperledger/fabric-peer:x86_64-1.0.0
docker pull hyperledger/fabric-ca:x86_64-1.0.0
docker pull hyperledger/fabric-ccenv:x86_64-1.0.0
docker pull hyperledger/fabric-baseimage:x86_64-0.4.7
docker pull hyperledger/fabric-baseos:x86_64-0.4.7
docker pull hyperledger/fabric-zookeeper:x86_64-1.0.0
docker pull hyperledger/fabric-javaenv:x86_64-1.0.0
docker pull hyperledger/fabric-membersrvc:latest

請注意每個映象的版本號！大多數往往缺少baseimage,baseos,membersrvc這三種。

2 錯誤彙總

1.ERRO 001 Cannot run peer because error when setting up MSP from directory........msp.......
2.ERRO 001 Cannot run peer because error when setting up MSP from directory /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp......

解決辦法：

這兩個問題都是因為fabric版本和docker映象版本不一致
檢視fabric branch：git branch -a

結果帶*就是你的branch，如果不是v1.0.0，就
git checkout v1.0.0

當然，也可以下載對應的映象(如果版本為v 1.1)：

cd $GOPATH/src/github.com/hyperledger/fabric/examples/e2e_cli/
source download-dockerimages.sh -c x86_64-1.1.0 -f x86_64-1.1.0

再檢視下fabric目錄下： make cryptogen。如果返回

CGO_CFLAGS=" " GOBIN=/opt/gopath/src/github.com/hyperledger/fabric/build/bin go install -tags "" -ldflags "-X github.com/hyperledger/fabric/common/tools/cryptogen/metadata.Version=1.0.1" github.com/hyperledger/fabric/common/tools/cryptogen
github.com/hyperledger/fabric/vendor/github.com/miekg/pkcs11
vendor/github.com/miekg/pkcs11/pkcs11.go:29:18: fatal error: ltdl.h: No such file or directory
compilation terminated.
Makefile:227: recipe for target 'build/bin/cryptogen' failed
make: *** [build/bin/cryptogen] Error 2

表明缺少ltdl.h檔案。執行以下命令：

apt-get install libtool libltdl-dev
make cryptogen

3 如果出現：

Error: Error endorsing chaincode: rpc error: code = Unknown desc = Error starting container: API error (404): {"message":"network e2ecli_default not found"}

解決辦法：

cd $GOPATH/src/github.com/hyperledger/fabric/examples/e2e_cli/base
gedit peer-base.yaml
開啟檔案後將e2ecli_default修改為e2e_cli_default

4 go語言的環境問題

注意：cd ~ 和 cd /home是不一樣的！！！

7 docker刪除相同的映象出錯解決：

8 出現DEBU 001 Returning existing local MSP

微信截圖_20181101174638.png

有一種解決方法是：

執行一下命令  vim /etc/hosts
增加以下內容
172.16.10.188 orderer.example.com

但是，我覺的這種方法沒有什麼效果，因為我執行了這句話後，也沒解決問題

後來，看到一篇帖子，終於解決了：

是因為環境遺留的問題

解決方式，重新關閉網路

./network_setup.sh down mychannel

當然，也有可能是e2e_cli檔案沒有許可權讀寫

後記：

我一開始是版本錯了，是v1.1 的版，下的docker映象卻是v1.0.0；

接下來，估計是由於前面執行過一次./network_setup.sh up ，所以有環境殘餘。
在執行完./network_setup.sh down mychannel後，
再啟動

./network_setup.sh up

root@cc-fibric:/home/cc/go/src/github.com/hyperledger/fabric/examples/e2e_cli# ./network_setup.sh up
setting to default channel 'mychannel'
mychannel
