How to Install Golang 1.12.1 on CentOS 7

Golang is a programming language developed by Google. Thanks to its versatility, simplicity and reliability, Golang has become one of the most popular programming languages in the open source community.

In this article, I will show you how to install the latest stable release of Golang on 64-bit Linux operating systems, in CentOS 7. At the time I wrote this article, the latest stable release of Golang was Golang 1.12.1

Step 1: Download and decompress the Golang 1.12.1 archive

if you are using a 64-bit Linux operating system, in CentOS 7 x64, you need to download the 64-bit version of Golang as below:

# cd

# wget https://dl.google.com/go/go1.12.1.linux-amd64.tar.gz

# tar -zxvf go1.12.1.linux-amd64.tar.gz -C /usr/local

Note: You can always find the download link to the latest release of Golang on the  golang official download page


Step 2: Setup GOROOT and PATH environment variables:

# echo 'export GOPATH=~/.go' | tee -a /etc/profile

# echo 'export GOROOT=/usr/local/go' | tee -a /etc/profile

# echo 'export PATH=$PATH:$GOROOT/bin:$GOPATH/bin' | tee -a /etc/profile

# source /etc/profile

Step 3: Test the installation

# go version

# go env

In addition, you can write a simple Golang program and give it a shot:

# cd

# mkdir -p src/hello

# cd

# vi hello.go

Populate the file ~/src/hello/hello.go with the following code segment:

package main import "fmt" func main() {     fmt.Printf("hello, world\n") }

Save and quit:

:wq!

Finally, run your first Golang program as follows:

# go run hello.go

If everything was done correctly, you will see the output:

hello world
