What is the method of installing Go on the CentOS 7 system, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can get something.

Here is how to install Go on a CentOS 7 system, along with how to install Go on Ubuntu 18.04. Go can be installed using either method 1 or method 2 below.

Introduction to Go

Go is an open source programming language with a novel type system that enables flexible modular program construction and makes programmers more efficient. Using the concurrency mechanism, it is easy to write programs that make full use of multicore and networked machines. As we all know, Go is efficient, clean, expressive and concise.

Go compiles quickly to machine code, but it has the convenience of garbage collection and the power of runtime reflection. It is a fast, statically typed compiled language that feels like a dynamically typed interpreting language.

How to install Go

We have two ways to install Go on CentOS 7 systems.

Method 1. Use the Go repository (for CentOS 7 only)

We will use the Go repository to ensure that we get the latest version:

Rpm-- import https://mirror.go-repo.io/centos/RPM-GPG-KEY-GO-REPO

Curl-s https://mirror.go-repo.io/centos/go-repo.repo | tee / etc/yum.repos.d/go-repo.repo

After adding the repository, install the golang package:

Sudo yum install golang

The Go binaries will be placed under / bin/go:

# which go

/ bin/go

Attachment: for Ubuntu 18.04system

For the Ubuntu 18.04 server, run:

$sudo add-apt-repository ppa:gophers/archive

$sudo apt-get update

$sudo apt-get install golang-go

Set $GOPATH:

Mkdir-p ~ / go/ {bin,pkg,src}

Echo 'export GOPATH='$HOME/go'' > > ~ / .bashrc

Echo 'export PATH='$PATH:$ {GOPATH//://bin:} / bin'' > > ~ / .bashrc

Method 2. Download Go manually

The second method involves downloading the Go file and installing it on the system.

First check the Go download page to get the latest version: https://yisu.com/linuxrj/2803.html

Ensure that wget is installed on the system:

Sudo yum install wget (for CentOS 7)

Sudo apt install wget (for Ubuntu 18.04)

Then download Go:

VER=1.9.2

Wget https://golangtc.com/static/go/1.9.2/go1.9.2.linux-amd64.tar.gz

Sudo tar-C / usr / local-xzf go1.9.2.linux-amd64.tar.gz

Rm go1.9.2.linux-amd64.tar.gz

Set the Go PATH variable:

Vim / .bashrc

Join:

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

Get the file of the PATH to update:

Source / etc/profile

Test:

Mkdir-p ~ / go/src/test

Vim ~ / go/src/test/test.go

Add print Hello Gophers message:

Package main

Import 'fmt'

Func main () {

Fmt.Printf ('Hello, Gophers\ n')

}

Build the test.go file:

Cd ~ / go/src/test

Run the binaries to test:

$. / test

Hello, Gophers

At this point, the installation of Go is complete.

What is go golang is a compiled language that can compile the code into machine code, and the compiled binaries can be deployed directly to the target machine without additional dependencies, so golang outperforms other interpretive languages and can use goroutine in golang to achieve concurrency. It provides a very elegant goroutine scheduler system that can easily generate millions of goroutine.
