运行fabric第一个示例e2e_cli
安装环境
我的系统是ubuntu 16.04，跑在Oracle VM VirtualBox 5.2.12虚拟机里边。
替换为国内的源
参考模板:16.04source
修改文件/etc/apt/source.list
使用阿里云的源，替换为
deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse

tar -C /usr/local -xzf go$VERSION.$OS-$ARCH.tar.gz设置环境变量
这里直接修改的是/etc/profile
设置GOPATH
设置为/opt/gopath 因为e2e_cli示例里边很多地方写死了该路径。
export GOPATH=/opt/gopath
export PATH=$PATH:/usr/local/go/bin设置系统PATH
export PATH=$PATH:/usr/local/go/bin 执行souce /etc/profile

docker安装
参考官方文档Get Docker CE for Ubuntu
SET UP THE REPOSITORY
Update the
aptpackage index:$ sudo apt-get updateInstall packages to allow
aptto use a repository over HTTPS:$ sudo apt-get install \ apt-transport-https \ ca-certificates \ curl \ software-properties-commonAdd Docker’s official GPG key:
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -Verify that you now have the key with the fingerprint
9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88, by searching for the last 8 characters of the fingerprint.$ sudo apt-key fingerprint 0EBFCD88 pub 4096R/0EBFCD88 2017-02-22 Key fingerprint = 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88 uid Docker Release (CE deb)
INSTALL DOCKER CE
Update the
aptpackage index.$ sudo apt-get updateInstall the latest version of Docker CE, or go to the next step to install a specific version:
$ sudo apt-get install docker-ceGot multiple Docker repositories?
If you have multiple Docker repositories enabled, installing or updating without specifying a version in the
apt-get installorapt-get updatecommand always installs the highest possible version, which may not be appropriate for your stability needs.To install a specific version of Docker CE, list the available versions in the repo, then select and install:
a. List the versions available in your repo:
$ apt-cache madison docker-ce docker-ce | 18.03.0~ce-0~ubuntu | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packagesb. Install a specific version by its fully qualified package name, which is package name (
docker-ce) “=” version string (2nd column), for example,docker-ce=18.03.0~ce-0~ubuntu.$ sudo apt-get install docker-ce=<VERSION>The Docker daemon starts automatically.
Verify that Docker CE is installed correctly by running the
hello-worldimage.$ sudo docker run hello-worldThis command downloads a test image and runs it in a container. When the container runs, it prints an informational message and exits.
docker compose安装
参考官方文档install-compose
Run this command to download the latest version of Docker Compose:
sudo curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-composeApply executable permissions to the binary:
sudo chmod +x /usr/local/bin/docker-composeTest the installation.
docker-compose --versionfabric下载
cd $GOPATH最好将GOPATH设置为/opt/gopath。e2e_cli示例里边很多地方写死了该路径。
创建目录，一样的，也是写死了路径
mkdir -p src/github.com/hyperledger下载fabric源代码
git clone https://github.com/hyperledger/fabric.git切换到1.0分支
git checkout release-1.0编译configtxgen工具
cd $GOPATH/src/github.com/hyperledger/fabric
make configtxgen编译后输出
Binary available as build/bin/configtxgen示例程序e2e_cli
下载镜像
进入到e2e_cli目录
cd $GOPATH/src/github.com/hyperledger/fabric/examples/e2e_cli/严格指定下载1.0.0版本
source download-dockerimages.sh -c x86_64-1.0.0 -f x86_64-1.0.0运行
切换到e2e_cli目录下，执行network_setup.sh up启动
cd $GOPATH/src/github.com/hyperledger/fabric/examples/e2e_cli/
sudo ./network_setup.sh up接下来开始踩坑了。
错误1 - 未终止的”s”命令
脚本文件generateArtifacts.sh 函数 replacePrivateKey中
sed $OPTS "s/CA1_PRIVATE_KEY/${PRIV_KEY}/g" docker-compose-e2e.yaml
sed $OPTS "s/CA2_PRIVATE_KEY/${PRIV_KEY}/g" docker-compose-e2e.yaml必须使用单引号。（实际我在telminal中是能执行的，不知道为什么在shell中不行）
sed $OPTS 's/CA1_PRIVATE_KEY/${PRIV_KEY}/g' docker-compose-e2e.yaml
sed $OPTS 's/CA2_PRIVATE_KEY/${PRIV_KEY}/g' docker-compose-e2e.yaml可能是我下载桌面版本ubuntu，安装是中文版。在服务器上是英文版没有遇到这个问题。

sudo apt install libltdl-dev错误3 - orderer节点启动失败
2018-08-15 09:41:58.640 UTC [grpc] Printf -> DEBU 003 grpc: addrConn.resetTransport failed to create client transport: connection error: desc = "transport: Error while dialing dial tcp: lookup orderer.example.com on 127.0.0.11:53: no such host"; Reconnecting to {orderer.example.com:7050 }
Error: Error connecting due to rpc error: code = Unavailable desc = grpc: the connection is unavailable 通过docker ps查看，orderer节点并未启动成功
查看network_setup.sh中的函数networkUp
function networkUp () {
if [ -f "./crypto-config" ]; then
echo "crypto-config directory already exists."
else
#Generate all the artifacts that includes org certs, orderer genesis block,
# channel configuration transaction
source generateArtifacts.sh $CH_NAME
fi
if [ "${IF_COUCHDB}" == "couchdb" ]; then
CHANNEL_NAME=$CH_NAME TIMEOUT=$CLI_TIMEOUT docker-compose -f $COMPOSE_FILE -f $COMPOSE_FILE_COUCH up -d 2>&1
else
CHANNEL_NAME=$CH_NAME TIMEOUT=$CLI_TIMEOUT docker-compose -f $COMPOSE_FILE up -d 2>&1
fi
if [ $? -ne 0 ]; then
echo "ERROR !!!! Unable to pull the images "
exit 1
fi
docker logs -f cli
}因为我们没有使用couchdb，最核心的就是这一行
CHANNEL_NAME=$CH_NAME TIMEOUT=$CLI_TIMEOUT docker-compose -f $COMPOSE_FILE up -d 2>&1
脚本文件network_setup.sh开头已经定义OMPOSE_FILE=docker-compose-cli.yaml
实际命令最后为：
docker-compose -f docker-compose-cli.yaml up -d
既然是orderer节点启动不起来，那就将orderer节点的信息单独拷贝出来，到新建的文件docker-compose-cli-test.yaml来测试，看启动失败的信息。
`docker-compose-cli-test.yaml文件内容：

services:

extends:

service: orderer.example.com
container_name: orderer.example.com通过docker-compose执行
sudo docker-compose -f docker-compose-cli-test.yaml up输出结果很多，重要信息在这
orderer.example.com | panic: Unable to bootstrap orderer. Error reading genesis block file: read /var/hyperledger/orderer/genesis.block: is a directory说明可能文件挂载除了问题。
查看docker-compose-base.yaml中的orderer.example.com目录挂载信息
volumes:
- ../channel-artifacts/genesis.block:/var/hyperledger/orderer/orderer.genesis.block
- ../crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/msp:/var/hyperledger/orderer/msp
- ../crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/tls/:/var/hyperledger/orderer/tls../channel-artifacts/genesis.block是一个文件，而被当做目录挂载了。说明没有被读到。
尝试给这一行加上引号
- "../channel-artifacts/genesis.block:/var/hyperledger/orderer/genesis.block"
再进行重新启动，发现OK了，问题解决了。
后来再去创建了一个docker工程测试验证了下。发现
- volumes去挂载目录，host path是相对路径是没有问题的
- volumes去挂载文件，host path得是绝对路径或者得加上引号
错误4 - network e2ecli_default not found
错误信息
Error: Error endorsing chaincode: rpc error: code = Unknown desc = error starting container: API error (404): {"message":"network e2ecli_default not found"}网上有不少人给出了解决方案，将peer-base.yaml文件中的
- CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=e2ecli_default改为
- CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=e2e_cli_default这样改是可以的。参考https://docs.docker.com/compose/networking/
真实原因是默认创建的网络名称为：$(目录名称)_default，而我们的这个示例项目目录名称为e2e_cli。因此网络名称为e2e_cli_deault。
可以通过命令查看
docker network ls输出结果
