B.2.2 环境变量配置

必要的环境变量

核心环境变量详解：

GOROOT：Go语言安装根目录
- 指向Go语言的安装位置
- 包含Go编译器、标准库等核心文件
- 通常无需手动设置，Go会自动检测
GOPATH：Go工作空间路径
- Go 1.11之前的工作空间模式使用
- 包含src、bin、pkg三个子目录
- Go 1.11+引入模块后变为可选
GOPROXY：Go模块代理服务器
- 用于下载Go模块的代理地址
- 提高模块下载速度和可靠性
- 支持多个代理地址，用逗号分隔
GOSUMDB：Go校验和数据库
- 用于验证模块完整性和安全性
- 防止模块被篡改
- 默认使用sum.golang.org
GO111MODULE：模块支持开关
- on：强制使用模块模式
- off：强制使用GOPATH模式
- auto：自动检测（默认）

# GOROOT: Go安装目录
export GOROOT=/usr/local/go

# GOPATH: 工作空间目录（Go 1.11+可选）
export GOPATH=$HOME/go

# PATH: 添加Go二进制文件路径
export PATH=$GOROOT/bin:$GOPATH/bin:$PATH

# GOPROXY: Go模块代理
export GOPROXY=https://goproxy.cn,direct

# GOSUMDB: 校验和数据库
export GOSUMDB=sum.golang.org

# GO111MODULE: 模块支持
export GO111MODULE=on

# GOOS: 目标操作系统
export GOOS=linux

# GOARCH: 目标架构
export GOARCH=amd64

# CGO_ENABLED: CGO支持开关
export CGO_ENABLED=1

配置文件设置

bash (.bashrc 或 .bash_profile)：

# Go环境配置
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$GOROOT/bin:$GOPATH/bin:$PATH
export GOPROXY=https://goproxy.cn,direct
export GO111MODULE=on

# 重新加载配置
source ~/.bashrc

zsh (.zshrc)：

# Go环境配置
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$GOROOT/bin:$GOPATH/bin:$PATH
export GOPROXY=https://goproxy.cn,direct
export GO111MODULE=on

# 重新加载配置
source ~/.zshrc

fish (config.fish)：

# Go环境配置
set -gx GOROOT /usr/local/go
set -gx GOPATH $HOME/go
set -gx PATH $GOROOT/bin $GOPATH/bin $PATH
set -gx GOPROXY https://goproxy.cn,direct
set -gx GO111MODULE on

    }
    defer f.Close()
    
    // 开始trace
    err = trace.Start(f)
    if err != nil {
        panic(err)
    }
    defer trace.Stop()
    
    // 你的应用程序代码
    for i := 0; i < 10; i++ {
        go func(id int) {
            time.Sleep(time.Millisecond * 100)
        }(i)
    }
    
    time.Sleep(time.Second)
