Golang安装和环境配置

安装golang:

下载安装包,国内地址:https://golang.google.cn/dl/

$ sudo tar -C /usr/local -xzf go1.12.5.linux-amd64.tar.gz  //解压

添加环境变量,修改/etc/profile 或$HOME/.profile或/etc/profile.d/目录的文件

$ sudo vi /etc/profile.d/brianconfig.sh  //添加以下内容
export GOROOT=/usr/local/go //定义GOROOT
export PATH=$PATH:/usr/local/go/bin // 添加go/bin到系统环境变量PATH中
export GOPATH=/work/wks_golang //添加GOPATH变量

查看golang版本:

$ go version
go version go1.12.5 linux/amd64

查看GOROOT

$ go env GOROOT
/usr/local/go

查看GOPATH

$ echo $GOPATH
/
/work/wks_golang

demo测试

在/work/wks_golang目录内,新建 src/hello, 创建hello.go:

package main
import "fmt"
func main() {
    fmt.Printf("hello, world\n")
}

使用go tool构建:

$ cd ./src/hello
$ go build

The command above will build an executable named hello in the directory alongside your source code. Execute it to see the greeting:

$ ./hello
hello, world

让ZSH支持自动补全

查看oh-my-zsh中是否有golang插件

$ ls ~/.oh-my-zsh/plugins/golang/
$ vi ~/.zshrc

修改~/.zshrc ,找到plugins数组添加:

plugins=(... golang)

官网设置GOPATH指南

GOPATH 在go1.8后默认是$HOME/go,也可以根据情况设定。

场景1 - Bash

修改 ~/.bash_profile,添加

export GOROOT=$HOME/go
export GOPATH=$HOME/go

启用使之生效

source ~/.bash_profile

场景2 - Zsh

修改~/.zshrc 添加:

export GOPATH=$HOME/go

启用使之生效

source ~/.zshrc
