Golang深入浅出golangMac优雅使用指南

Mac os安装golang开发环境

2018-08-13  本文已影响6人  夏之绘

为了能够愉快地进行golang编程,我们需要安装以下几样东西:

docker 其实是可选的,它可以把应用程序打包为可移植的、自给自足的容器。这样一来,你就可以在本地生成golang程序的docker镜像,直接扔到测试环境,便可以进行测试了,不需要再进行代码上传,环境配置等操作了。
如果你觉得暂时用不到,也可以先不装。

1 安装brew


HomeBrew图标

Homebrew有点类似于Linux操作系统中的apt-get(Ubuntu)、yum(yum),Mac的操作系统中使用它解决包依赖问题,套用官方的话来说:

Homebrew 能干什么?

使用 Homebrew 安装 Apple 没有预装但 你需要的东西

让我们开始安装吧!

在命令行输入以下指令

fabric:~ fabric$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

出现以下内容,安装成功

==> Installation successful!

==> Homebrew has enabled anonymous aggregate user behaviour analytics.
Read the analytics documentation (and how to opt-out) here:
  https://docs.brew.sh/Analytics.html

==> Next steps:
- Run `brew help` to get started
- Further documentation: 
    https://docs.brew.sh

2 安装并配置golang

我们发现最新的有1.9可以使用

fabric:~ fabric$ brew install go@1.9
Updating Homebrew...
==> Downloading https://homebrew.bintray.com/bottles/go@1.9-1.9.7.high_sierra.bottle.tar.gz
######################################################################## 100.0%
==> Pouring go@1.9-1.9.7.high_sierra.bottle.tar.gz
==> Caveats
A valid GOPATH is required to use the `go get` command.
If $GOPATH is not specified, $HOME/go will be used by default:
  https://golang.org/doc/code.html#GOPATH

You may wish to add the GOROOT-based install location to your PATH:
  export PATH=$PATH:/usr/local/opt/go@1.9/libexec/bin

This formula is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/go@1.9/bin:$PATH"' >> ~/.bash_profile

==> Summary
  /usr/local/Cellar/go@1.9/1.9.7: 7,668 files, 294.2MB
fabric:~ fabric$ vim ~/.bashrc

将下面内容添加进上面的文件

#GOROOT
export GOROOT=/usr/local/opt/go\@1.9

#GOPATH
export GOPATH=$HOME/Documents/code/gopath

#GOPATH root bin
export PATH=$PATH:$GOROOT/bin

GOPATH可以根据个人习惯设置为其他目录
本人习惯在home目录下的Documents里新建一个code目录,用于存放各种语言的代码,比如Documents/code/gopath用于存放golang的代码,Documents/code/www用于存放php代码...

让改动生效

fabric:~ fabric$ source ~/.bashrc
fabric:~ fabric$  go env
GOARCH="amd64"
GOBIN=""
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"
GOOS="darwin"
GOPATH="/Users/fabric/Documents/code/gopath"
GORACE=""
GOROOT="/usr/local/opt/go\@1.9"

2.2 方法二:从源码安装golang

这个在我另外一篇文章做了详细的叙述,详情请见《修改并编译golang源码》

3 安装配置git


git图标

3.1 用brew安装git

fabric:~ fabric$ brew install git
==> Downloading https://homebrew.bintray.com/bottles/git-2.18.0.high_sierra.bott
######################################################################## 100.0%
==> Pouring git-2.18.0.high_sierra.bottle.tar.gz
==> Caveats
Bash completion has been installed to:
  /usr/local/etc/bash_completion.d

zsh completions and functions have been installed to:
  /usr/local/share/zsh/site-functions

Emacs Lisp files have been installed to:
  /usr/local/share/emacs/site-lisp/git
==> Summary
  /usr/local/Cellar/git/2.18.0: 1,488 files, 295.6MB

3.2 配置git

3.2.1 查看用户名和邮箱地址

fabric:~ fabric$ git config user.name
fabric:~ fabric$ git config user.email

3.2.2 修改用户名和邮箱地址

fabric:~ fabric$ git config --global user.name "你的用户名"
fabric:~ fabric$ git config --global user.email "你的邮箱地址"

3.2.3 生成SSH KEY

为了向github自己的仓库提交代码,我们需要设置SSH KEY

fabric:~ fabric$ ssh-keygen -t rsa -C 你的邮箱地址
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/fabric/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /Users/fabric/.ssh/id_rsa.
Your public key has been saved in /Users/fabric/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:生成的密钥指纹 你的邮箱地址
The key's randomart image is:
+---[RSA 2048]----+
生成的密钥randomart image 
+----[SHA256]-----+
fabric:~ fabric$ cat /Users/fabric/.ssh/id_rsa.pub 
你的公钥

github设置公钥的地方:

右上角头像下拉选项 -> Settings -> SSH and GPG keys

设置公钥
cd 你的代码目录
git clone 你的代码git仓库地址

4 安装docker


docker

Homebrew 的 Cask 已经支持 Docker for Mac,因此可以很方便的使用 Homebrew Cask 来进行安装:

4.1 用brew安装docker

fabric:~ fabric$ brew cask install docker

在载入 Docker app 后,点击 Next,可能会询问你的 macOS 登陆密码,你输入即可。之后会弹出一个 Docker 运行的提示窗口,状态栏上也有有个如下所示的小鲸鱼的图标:


docker图标

验证一下是不是安装成功了呢,输入以下命令

fabric:~ fabric$  docker version
Client:
 Version:           18.06.0-ce
 API version:       1.38
 Go version:        go1.10.3
 Git commit:        0ffa825
 Built:             Wed Jul 18 19:05:26 2018
 OS/Arch:           darwin/amd64
 Experimental:      false

Server:
 Engine:
  Version:          18.06.0-ce
  API version:      1.38 (minimum version 1.12)
  Go version:       go1.10.3
  Git commit:       0ffa825
  Built:            Wed Jul 18 19:13:46 2018
  OS/Arch:          linux/amd64
  Experimental:     true

4.2 下载app安装

如果需要手动下载,请点击以下链接下载 StableEdge 版本的 Docker for Mac。

如同 macOS 其它软件一样,安装也非常简单,双击下载的 .dmg 文件,然后将鲸鱼图标拖拽到 Application 文件夹即可。


拖拽安装

4.3 给咱的docker提提速

由于一些大家都知道的原因,我们拉取Docker镜像会很缓慢,我们可以通过添加加速器来解决。比如网易的镜像地址:

http://hub-mirror.c.163.com

点击右上角的小鲸鱼图标 -> Perferences,然后选择下图中的Daemon->Registry mirrors,添加上面的地址


增加仓库

应用改动后,docker会重启,我们来看一下是否配置成功

fabric:~ fabric$ docker info
Containers: 0
 Running: 0
 ...
Registry Mirrors:
 http://hub-mirror.c.163.com/
Live Restore Enabled: false

可以看到,配置的地址已经生效了。

5 安装Goland


Goland

这里只是提供个工具推荐,安装Goland的文章网上一抓一大把,我就不赘述了。

如此一来,整个安装过程便完成了!
