66d83bfb5a9ede000e33c6579a91a29e6b101829ad41fffb5c5bb6c900e109d9  go1.12.7.linux-amd64.tar.gz

1.1 go 国内下载

wget https://studygolang.com/dl/golang/go1.15.7.linux-amd64.tar.gz

2，Linux go 安装

# tar -zxvf go1.12.7.linux-amd64.tar.gz

# ls -lh
drwxr-xr-x 10 root root 4.0K Jul  8 21:29 go
# chown -R root:root ./go
drwxr-xr-x 10 root root 4.0K Jul  8 21:29 go
# mv go /usr/local/

• 或者

tar -C /usr/local/ -zxvf go1.14.4.linux-amd64.tar.gz

3，配置环境

# vim ~/.profile
# cat ~/.profile
export GOPATH=$HOME/work
export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin
# source ~/.profile

3.1 GOPATH 默认为当前用户目录下go目录

# go env GOPATH
/root/go

• 环境变量可以设置为

export GOPATH=$HOME/go
export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin

# source .profile
# go version
go version go1.15.7 linux/amd64

4，测试go

# go version
go version go1.7.4 linux/amd64

# mkdir -p $HOME/work/src
# pwd
/root/work/src/
# touch hello.go
cat hello.go 
package main

import "fmt"

func main() {
            fmt.Printf("Hello, World!\n")
    }
# go build hello.go 
# go run hello.go 
Hello, World!
# ls -lh
总用量 2.0M
-rwxr-xr-x 1 root root 2.0M 7月   9 22:15 hello
-rw-r--r-- 1 root root   83 7月   9 21:42 hello.go
# ./hello 
Hello, World!

# touch hello.go
cat hello.go 
package main

import "fmt"

func main() {
            fmt.Printf("Hello, World!\n")
    }
# go build hello.go 
# go run hello.go 
Hello, World!
# ls -lh
总用量 2.0M
-rwxr-xr-x 1 root root 2.0M 7月   9 22:15 hello
-rw-r--r-- 1 root root   83 7月   9 21:42 hello.go
# ./hello 
Hello, World!

卸载go

• 查看安装

# which go
/usr/bin/go

# cd /usr/local/
# ls -l | grep go
drwxr-xr-x 10 root root 4096 10月 18 06:02 go

# cd /usr/bin/
# ls -l | grep go
lrwxrwxrwx 1 root root          21 9月   5 03:03 go -> ../lib/go-1.13/bin/go
lrwxrwxrwx 1 root root          24 9月   5 03:03 gofmt -> ../lib/go-1.13/bin/gofmt

• 卸载

rm -rf /usr/local/go /usr/bin/go /usr/bin/gofmt

# rm -rf /usr/local/go
# rm -rf /usr/bin/go
# rm -rf /usr/bin/gofmt

• 安装

# tar -zxvf go1.13.3.linux-amd64.tar.gz -C /usr/local
# ln -s /usr/local/go/bin/* /usr/bin/
# go version
go version go1.13.3 linux/amd64

5，go1.14.4

tar -C /usr/local/ -zxvf go1.14.4.linux-amd64.tar.gz

• vim /etc/profile

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

source /etc/profile

# which go
/usr/local/go/bin/go
# go version
go version go1.14.4 linux/amd64

# go env
GOPATH="/root/go"
GOROOT="/usr/local/go"

6，go设置国内代理

go env -w GOPROXY=https://goproxy.cn,direct

go env -w GO111MODULE=on

7，go 1.15.7

tar -C /usr/local/ -zxvf go1.15.7.linux-amd64.tar.gz

vim ~/.profile

export GOPATH=$HOME/go
export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin

# source .profile
# go version
go version go1.15.7 linux/amd64
