安装

解压压缩包，安装到/usr/local目录，然后配置PATH变量到.bashrc，并引入当前环境，使用go version查看版本

[root@iZ2zee2m456rb6bde98jpkZ ~]# tar zxf go1.18.3.linux-amd64.tar.gz -C /usr/local/
[root@iZ2zee2m456rb6bde98jpkZ ~]# echo "export PATH=/usr/local/go/bin:$PATH" >> .bashrc
[root@iZ2zee2m456rb6bde98jpkZ ~]# source .bashrc 
[root@iZ2zee2m456rb6bde98jpkZ ~]# go version
go version go1.18.3 linux/amd64

配置软件包代理

[root@iZ2zee2m456rb6bde98jpkZ ~]# echo "export GOPROXY=https://proxy.golang.com.cn,direct" >> .bashrc
[root@iZ2zee2m456rb6bde98jpkZ ~]# source .bashrc 
[root@iZ2zee2m456rb6bde98jpkZ ~]# go env |grep GOPROXY
GOPROXY="https://proxy.golang.com.cn,direct"

运行

新建目录test1，用vi main.go编辑文件

package main

import "fmt"

func main() {
    fmt.Println("golang install test")
}

go run main.go 运行

[root@iZ2zee2m456rb6bde98jpkZ test1]# go run main.go 
golang install test
