超级账本的环境安装最麻烦的就是墙,很多问题都是墙导致的,越过墙之后一切就非常简单。我找了一个可以直通港岛的网络后几乎没有遇到问题。我是在Mac下安装的,由于有系统洁癖,我使用虚拟机来安装fabric的编译环境。在fabric/devenv目录下其实已经提供了在虚拟机下面配置的脚本,整个操作也非常简单。

配置本地环境

依次安装:

  1. GIT
  2. GO(此处有墙,如果在虚拟机上编译代码此处不是必须的)
  3. Vagrant
  4. VirtualBox

然后设置GOPATH:

vim ~/.bash_profile
加入下面的设置,保存后退出
# GO configuration
export GOPATH=/Users/[your_name]/workspace/gopath
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOBIN
使配置生效:
source ~/.bash_profile

至此,环境配置完毕。下面开始下载代码:

cd $GOPATH/src
mkdir -p github.com/hyperledger
cd github.com/hyperledger
git clone https://github.com/hyperledger/fabric.git

此处注意:强烈建议使用最新的代码。因为超级账本依赖很多第三方的库,而第三方库可能已经发生改变,最新的代码是基于这些改变的。

至此,本地环境配置完毕。

使用Vagrant启动并配置虚拟机

cd $GOPATH/src/github.com/hyperledger/fabric/devenv
vagrant up

此处有墙,根据网络速度耗时可能会比较长,甚至可能由于网络原因出错中断,出错之后重新开始。完成之后使用下面的命令登录虚拟机:

vagrant ssh
说明一下,vagrant基于Vagrantfile,Vagrantfile会执行setup.sh来完成虚拟机的配置。我们可以根据自己的需要来修改配置,修改完成后执行下面的命令会重新配置虚拟机:
vagrant up --provision
使用vagrant ssh登录后就可以直接编译了
# -------------------------------------------------------------
# This makefile defines the following targets
#
#   - all (default) - builds all targets and runs all tests/checks
#   - checks - runs all tests/checks
#   - desk-check - runs linters and verify to test changed packages
#   - configtxgen - builds a native configtxgen binary
#   - configtxlator - builds a native configtxlator binary
#   - cryptogen  -  builds a native cryptogen binary
#   - peer - builds a native fabric peer binary
#   - orderer - builds a native fabric orderer binary
#   - release - builds release packages for the host platform
#   - release-all - builds release packages for all target platforms
#   - unit-test - runs the go-test based unit tests
#   - verify - runs unit tests for only the changed package tree
#   - profile - runs unit tests for all packages in coverprofile mode (slow)
#   - test-cmd - generates a "go test" string suitable for manual customization
#   - behave - runs the behave test
#   - behave-deps - ensures pre-requisites are available for running behave manually
#   - gotools - installs go tools like golint
#   - linter - runs all code checks
#   - license - checks go source files for Apache license header
#   - native - ensures all native binaries are available
#   - docker[-clean] - ensures all docker images are available[/cleaned]
#   - docker-list - generates a list of docker images that 'make docker' produces
#   - peer-docker[-clean] - ensures the peer container is available[/cleaned]
#   - orderer-docker[-clean] - ensures the orderer container is available[/cleaned]
#   - tools-docker[-clean] - ensures the tools container is available[/cleaned]
#   - protos - generate all protobuf artifacts based on .proto files
#   - clean - cleans the build area
#   - clean-all - superset of 'clean' that also removes persistent state
#   - dist-clean - clean release packages for all target platforms
#   - unit-test-clean - cleans unit test state (particularly from docker)
#   - basic-checks - performs basic checks like license, spelling and linter
#   - enable_ci_only_tests - triggers unit-tests in downstream jobs. Applicable only for CI not to
#     use in the local machine.
#   - docker-thirdparty - pulls thirdparty images (kafka,zookeeper,couchdb)

第一次直接使用make all,会全部编译所有的模块并生产docker镜像,可以使用docker images查看镜像。编译完成后会有各种测试,可能失败。我没有管它,至少目前的运行还是顺畅的。

可能遇到的问题:

下面是可能遇到的问题,做个记录以备参考
