# 环境安装

## 安装介质

安装包下载地址： <https://golang.org/dl/>

支持系统：

| 操作系统    | 安装包                          |
| ------- | ---------------------------- |
| centos  | go1.10.2.linux-amd64.tar.gz  |
| windows | go1.10.2.windows-amd64.zip   |
| MacOS   | go1.10.2.darwin-amd64.tar.gz |

## Centos

1、下载安装介质

下载二进制包 `go1.10.2.linux-amd64.tar.gz`

2、解压

解压二进制包到`/usr/local`目录下，解压后在`/usr/local`目录下会多出一个`go`目录

```
tar -C /usr/local -xzvf go1.10.2.linux-amd64.tar.gz
```

3、设置环境变量

首先创建环境`GOROOT`，值设为`/usr/local/go`；然后把`$GOROOT/bin`加入到环境变量`PATH`中去。\
具体操作为，在`/etc/profile`尾部添加如下两行

```
export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin
```

然后执行如下命令，使环境变量生效

```
source /etc/profile
```

4、验证

执行以下命令，查看go版本信息

```
$ go version
go version go1.10.2 linux/amd64
```

## Windows

1、下载安装介质

下载最新版本的go安装包，有.msi和.zip两种格式，.msi是安装版，.zip是绿色版，这里我们选择 zip

2、解压安装包

把zip包解压到 `D:\GreenSoftware` 目录下，此时在go的根目录就是 `D:\GreenSoftware\go`

3、创建环境变量GOROOT

添加环境变量GOROOT，值设为 `D:\GreenSoftware\go`

4、 添加GOROOT到Path中

把`D:\GreenSoftware\go\bin`路径添加到Path中，即在Path的后面添加 `;%GOROOT%\bin`

5、 验证

执行以下命令，查看go的版本信息

```
E:\> go version
go version go1.10.1 windows/amd64
```

### MacOS

1、下载

下载archive类型的压缩包`go1.10.2.darwin-amd64.tar.gz`

2、解压

把上面的包解压到`/usr/local`目录下，解压后在`/usr/local`下便会多出一个`go`目录

```
sudo tar -C /usr/local -xzvf go1.10.2.darwin-amd64.tar.gz
```

3、设置环境变量

首先创建环境`GOROOT`，值设为`/usr/local/go`；然后把`$GOROOT/bin`加入到环境变量`PATH`中去。\
具体操作为，在`~/.profile`尾部添加如下两行

```
export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin
```

然后执行如下命令，使环境变量生效

```
source ~/.profile
```

4、验证

执行以下命令，查看go版本信息

```
$ go version
go version go1.10.2 linux/amd64
```
