Heperledger fabric v1.3.0阿里云环境配置及运行e2e案例

如何使用阿里云服务器部署fabric, 其实大部分流程和物理机相同,但还是有不同的地方的

1. 创建云服务器

申请云服务器的时候,我们是在阿里云申请的按需, 系统选择的是ubuntu 16.04,注意最低配置是4G的, 否则在运行e2e案例的时候kafka启动不起来.

2.安装go

export PATH=$PATH:/usr/local/go/bin 
export GOROOT=/usr/local/go 
export GOPATH=$HOME/go 
export PATH=$PATH:$HOME/go/bin

3.安装 docker 环境

4.安装docker-compose

$ curl -L [https://get.daocloud.io/docker/compose/releases/download/1.10.1/docker-compose-](https://get.daocloud.io/docker/compose/releases/download/1.10.1/docker-compose-)`uname -s`-`uname -m` > ~/docker-compose

$ sudo mv ~/docker-compose /usr/local/bin/docker-compose
$ chmod +x /usr/local/bin/docker-compose
至此,docker-compose 安装完毕!! 输入docker-com ,按tab键,看看能否自动补全,若能自动补全,则说明docker-compose安装成功!!

5. fabric源码及fabric的镜像

5.1 fabric源码

在 $GOPATH/src/github.com/heperledger路径下,把代码拉下来

若是没有路径,则手动创建

$ cd $GOPATH
$ mkdir -p src/github.com/hyperledger
$ cd src/github.com/hyperledger

拉取代码:

$ git clone -b release-1.3.0 https://github.com/hyperledger/fabric

若是拉取速度太慢的话,可以先在本地clone, 然后再scp到云服务器上..

5.2 fabric镜像

在 $GOPATH/src/github.com/heperledger路径下, 下载 fabric-samples

$ git clone https://github.com/hyperledger/fabric-samples.git

将fabric/scripts/bootstrap.sh 文件拷贝到 fabric-samples 文件夹下

$ cp ../fabric/scripts/bootstrap.sh ./

修改bootstrap.sh权限

$ chmod +x bootstrap.sh

运行bootstrap.sh, 开始拉取镜像, 时间略长,需要耐心等待..

$ ./bootstrap.sh

拉取完之后, $ docker images 查看镜像状态

5.3 运行 first-network 案例

5.4 运行 e2e 案例

$ cd $GOPATH/src/github.com/hyperledger/fabric/examples/e2e_cli/
$ ./network_setup.sh up
在这里会报错的:

!!!!!!!!!!!!!!! Ordering Service is not available, Please try again ... !!!!!!!!!!!!!!!!
================== ERROR !!! FAILED to execute End-2-End Scenario ==================

docker ps -a 查看各个容器的状态, orderer或者peer呈现Exit状态.

docker logs 容器id 查看未启动的docker容器的日志, 会看到如下错误:

fatal error: unexpected signal during runtime execution
[signal SIGSEGV: segmentation violation code=0x1

报错原因,请点这...

解决办法: 更新docker compose yaml模板，为所有的节点（如orderer, peer, ca, cli等）添加环境变量 GODEBUG=netdns=go 以强制使用pure Go resolver.

需要在 e2e文件夹中,对以下文件添加环境变量 GODEBUG=netdns=go

在e2e案例中,需要更改4个文件
examples/e2e_cli/base/docker-compose-base.yaml
examples/e2e_cli/base/peer-base.yaml
examples/e2e_cli/docker-compose-cli.yaml
examples/e2e_cli/docker-compose-e2e.yaml

比如:

若是kafka启动不起来,那可能是因为云服务器的配置太低了,比如说是1g内存的

跑起来之后,进入cli容器

$ docker exec -it cli bash

从a 给 b转 20块钱:

$ peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n mycc --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses peer0.org2.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["invoke","a","b","20"]}'

执行完之后,再查询一下 a,b的余额, 分别是 70 和 230 了, 这就表明fabric的环境已经搭建完毕,并且成功运行了e2e案例!!!

关闭案例: $ ./network_setup.sh down
