7. CentOS 7에서 Go 언어 설치하기

[root@www ~]# yum -y install git

[root@www ~]# wget -q https://storage.googleapis.com/golang/getgo/installer_linux

[root@www ~]# chmod +x installer_linux

[root@www ~]# ./installer_linux

Welcome to the Go installer!

Downloading Go version go1.16.5 to /root/.go

This may take a bit of time...

Downloaded!

Setting up GOPATH

GOPATH has been set up!

One more thing! Run `source /root/.bash_profile` to persist the

new environment variables to your current session, or open a

new shell prompt.

[root@www ~]# source /root/.bash_profile

[root@www ~]# go version

go version go1.16.5 linux/amd64

[root@www ~]#

[root@www ~]# cat .bash_profile

# .bash_profile

# Get the aliases and functions

if [ -f ~/.bashrc ]; then

. ~/.bashrc

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

export PATH=$PATH:/root/.go/bin

export GOPATH=/root/go

export PATH=$PATH:/root/go/bin

[root@www ~]#

소스로 설치하기

[root@www ~]# cd /usr/local/

[root@www local]# wget https://golang.org/dl/go1.16.5.linux-amd64.tar.gz --no-check-certificate

실행파일 path 환경등록

# vi ~/.bash_profile

실생PATH에 추가

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

# source ~/.bash_profile

GOROOT 지정 (선택사항)

: Go가 설치된 곳의 위치를 환경에 설정한다.

- 환경에 GOROOT추가

export GOROOT=/usr/local/go

- 환경적용

source ~/.bash_profile

GOPATH 지정 (필수, go get -u 패키지주소 로 패키지 설치시 GOPATH에 설치됨)

: Go 는 실제 프로그램을 할 곳인 GOPATH를 지정해야 함.(여기서는 /usr/local/go-work 를 지정할것임.)

- 일단 go-work폴더를 /usr/local하위에 만든다.

mkdir /usr/local/go_work

- 환경에 GOPATH 추가

export GOPATH=/usr/local/go_work

- 환경적용

source ~/.bash_profile

[jklee@localhost home]$ vi ~/.bash_profile

# .bash_profile

# Get the aliases and functions

if [ -f ~/.bashrc ]; then

. ~/.bashrc

# User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH

export GOPATH=/home/jklee/go

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

[jklee@localhost home]$ source ~/.bash_profile

go 설치 확인해보기 (go 명령어로 version이 잘 나오면 설치가 잘 된 것임.)

go version

[jklee@localhost home]$ go version

go version go1.16.5 linux/amd64

[jklee@localhost home]$
