go 环境搭建

作者:互联网

1,下载

Golang官网下载地址:https://golang.google.cn/dl/

 

2,解压到指定目录

 

3,运行go 

获取环境变量修改方法

go help env
usage: go env [-json] [-u] [-w] [var ...]

Env prints Go environment information.

By default env prints information as a shell script
(on Windows, a batch file). If one or more variable
names is given as arguments, env prints the value of
each named variable on its own line.

The -json flag prints the environment in JSON format
instead of as a shell script.

The -u flag requires one or more arguments and unsets
the default setting for the named environment variables,
if one has been set with 'go env -w'.

The -w flag requires one or more arguments of the
form NAME=VALUE and changes the default settings
of the named environment variables to the given values.

For more about environment variables, see 'go help environment'.

linux 现在环境变量

root@ubuntu:~# go env
GO111MODULE="on"
GOARCH="amd64"
GOBIN=""
GOCACHE="/root/.cache/go-build"
GOENV="/root/.config/go/env"
GOEXE=""

root@ubuntu:~# 

 设置/etc/profile环境变量

设置GOPATH环境变量

修改/etc/profile系统环境变量文件,写入GOPATH信息以及go sdk路径
#for go env

export GOROOT=/home/goenv/go
export PATH=$PATH:$GOROOT/bin

读取/etc/profile,立即生效

source /etc/profile     #读取环境变量

  

 修改方法

go env -w GOPROXY=https://goproxy.cn/
go env -w GO111MODULE=on

  

想在linux 同时设置 x64,x86的环境失败了.

GOCACHE="/root/.cache/go-build"
GOENV="/root/.config/go/env"

GOROOT="/home/goenv/go"
会同时修改.只有用2台机器来配置环境变量
