golang

1. golang安装

采用直接下载官方Linux系统golang安装包go1.16.2.linux-amd64.tar.gz安装

参考

$ sudo rm -rf /usr/local/go
$ sudo tar -C /usr/local -xzf go1.16.2.linux-amd64.tar.gz

$ vi ~/.profile
if [ -d "/usr/local/go/bin" ] ; then
    PATH="$PATH:/usr/local/go/bin"
fi
$ source ~/.profile

$ go version
go version go1.16.2 linux/amd64

hello.go

package main

import "fmt"

func main() {

  fmt.Println("hello go语言");
}

$ go build hello.go
$ ./hello

2.1 解决问题

1. 无法访问proxy.golang.org的问题

    $ go get rsc.io/quote
    go get: module rsc.io/quote: Get "https://proxy.golang.org/rsc.io/quote/@v/list": dial tcp 216.58.200.49:443: i/o timeout
    $ go env -w GOPROXY=https://goproxy.cn
    $ go get rsc.io/quote
    go: downloading rsc.io/quote v1.5.2
    go: downloading rsc.io/sampler v1.3.0
    go: downloading golang.org/x/text v0.0.0-20170915032832-14c0d48ead0c
    go get: added rsc.io/quote v1.5.2
