下载 Go 安装包

可以到 官网下载地址 去下载 Go 语言的安装包，由于之前安装的是 CentOS 系统，所以这里选择的是 linux 版本的 Go 安装包——go1.15.linux-amd64.tar.gz

上传 Go 安装包到 CentOS

上传可以直接粘贴复制，由于很多时候复制粘贴会不成功，所以可以使用第三方工具（如SecureCRT或Xftp）来进行上传

准备工作

• 新建一个 soft 文件夹，用来存放 go 安装包

  mkdir -p /soft

• 修改 IP 地址为：192.168.80.100，方便后续使用 ```bash vim /etc/sysconfig/network-scripts/ifcfg-ens33

THOD=none BROWSER_ONLY=no BOOTPROTO=static IPADDR=192.168.80.100 NETMASK=255.255.255.0 GATEWAY=192.168.80.2 NAME=ens33 DEVICE=ens33 ONBOOT=yes

systemctl restart network

# 解压 Go 安装包
将 Go 安装包解压到 /usr/local/ 目录
```bash
tar -xvf go1.15.linux-amd64.tar -C /usr/local/

-C 选项的作用是：指定需要解压到的目录

修改环境变量

• 编辑 /etc/profile 配置文件 ```bash vim /etc/profile

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

- 使配置文件临时生效
```bash
source /etc/profile

验证 Go 环境

验证环境配置

which go

检查 go 的版本

go version
