Hyperledger Fabric 2.0 debug 环境准备

0. 环境

---

Fabric v2.0.1
go version go1.13.7 darwin/amd64
GoLand 2019.3

1. 转换为 go module

---

也可不使用 go module 管理依赖，设置 GO111MODULE=off

到目前为止 Fabric 还没有启用 go module 管理依赖，首先将工程转换为 go module 工程。

go mod init 会根据 Gopkg.toml、Gopkg.lock 生成依赖并添加到 go.mod 中，期间会访问 google.com 的一些包，go mod init 过程中不会使用 GOPROXY，因此设置HTTP_PROXY ，否则 timeout 的依赖解析不会添加 go.mod 中，后续可能下载不匹配的依赖版本。

cd github.com/hyperledger/fabric
git checkout v2.0.1
HTTP_PROXY=http://127.0.0.1:8010 HTTPS_PROXY=http://127.0.0.1:8010 go mod init

个人理解 GoLand 即使启用了 Vendoring mode 还是会以 go module 为主管理 vendor 目录，可能误更新 vendor 目录。可以通过 git status 检查vendor 是否改动。

编译

make orderer 遇到如下错误：

make: *** [build/bin/orderer] Error 1

解决办法，构建时加上 -mod=vendor 选项，增加GO_BUILD_FLAGS变量修改 Makefile 209行如下：

...
GO_BUILD_FLAGS ?= -mod=vendor
$(BUILD_DIR)/bin/%: GO_LDFLAGS = $(METADATA_VAR:%=-X $(PKGNAME)/common/metadata.%)
$(BUILD_DIR)/bin/%:
	@echo "Building $@"
	@mkdir -p $(@D)
	GOBIN=$(abspath $(@D)) go install "$(GO_BUILD_FLAGS)" -tags "$(GO_TAGS)" -ldflags "$(GO_LDFLAGS)" $(pkgmap.$(@F))
	@touch $@
...

2. Fabric 网络

---

使用 sampleconfig 搭建 Fabric 开发调试网络

Bash 脚本

Mac 或 Linux 环境可通过脚本 快速准备环境。Windows Cygwin 未经测试

脚本使用方式：

1. 新建一个目录，如 /tmp/fabric
2. 将下面的 fab.sh 内容拷贝到新建目录下 fab.sh 文件中
3. 设置执行权限 chmod u+x fab.sh
4. 快速创建 ./fab.sh new
5. fab.sh 生成 utils.sh 辅助脚本可用于简化操作 source utils.sh ，之后使用其提供的函数
6. 清理 ./fab.sh clean

fab.sh

手动搭建

cd $TMP，以下以当前工作目录为 $TMP

链接编译输出到 $TMP 目录

ln -s /path/to/fabric_source/build/bin bin

设置 FABRIC_CFG_PATH ，开启新终端主要设置配置路径变量

export FABRIC_CFG_PATH=$(pwd)

生成网络配置创世块，并启动 orderer

bin/configtxgen -profile SampleDevModeSolo -channelID sys-channel -outputBlock ./channel-artifacts/genesis.block

修改 orderer.yaml 文件

General:
    BootstrapFile: channel-artifacts/genesis.block

FileLedger:
    # Location: The directory to store the blocks in.
    # NOTE: If this is unset, a new temporary location will be chosen every time
    # the orderer is restarted, using the prefix specified by Prefix.
    Location: production/orderer
