Go is an open-source (BSD license) programming language that was born with the objective of allowing the creation of efficient and easily distributable applications. So, it has binaries for Windows, Mac OS and of course, for Linux.

So, in this post, I will install it and create a “Hello World” file for the test.

Download and install Go Language on Debian 11 /10

Go Language is cross-platform which makes it available for Linux. However, first you have to download the binaries from the project website. But we will use the terminal that is faster and more efficient.

First, make sure you have wget installed on your computer.

:~$ sudo apt install wget

Then proceed to download Go Language. At the time of writing this post, the latest stable version is 1.17

:~$ wget -c https://golang.org/dl/go1.17.linux-amd64.tar.gz -O go.tar.gz

Then, decompress it.

:~$ tar xvf go.tar.gz

Now you have to change the folder permissions. Besides moving it to another location like /usr/local/.

:~$ sudo chown -R root:root go
:~$ sudo mv go /usr/local

Then, it is necessary to make some modifications to the user’s bash profile in order to use Go. Open the configuration file and add the following:

:~$ sudo nano ~/.profile

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

Save the changes (CTRL + O) and close the file (CTRL + X).

With this, Go is ready for work. You can check it by showing the version of the program.

:~$ go version

Now with a “hello world” we’ll see that everything works.

Testing the installation

As I said before, the best way to test the installation is to run a real code. For this, we will use the typical “Hello World”.

First, we’ll create the directory structure. In our Home, we will create a folder for the project called work. Inside a folder called src where the source code files will go. In it, a folder called hello and inside the file hello.go. Something like this is the directory structure. The folders work and hello can be called differently.

:~$ mkdir -p $HOME/work/src/hello

Now, create the Go file and add the following:

:~$ nano ~/work/src/hello/hello.go

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

Again, save the changes and close the file.

:~$ go build hello
:~$ go install hello
:~$ hello

So, enjoy it.

Conclusion

GO is a very popular language and every day it is more and more popular. It’s simple but very powerful, besides being open source. As you have seen, its installation is really simple.

Go is a programming language created in 2007 by Google. It was initially intended to be an internal coding standard for the company’s own infrastructure, but its potential prompted it to go on the air. Go is a concurrent and compiled programming language inspired by C syntax. It has been developed by Google, and its initial designers are Robert Griesemer, Rob Pike and Ken Thompson. It is cross-platform because it has binaries for Windows, Linux, macOS, and FreeBSD.

Some of its features are:

• Go uses a syntax similar to C.
• In teh same way, Go uses statically typed and is as efficient as C.
• Go has many of the features and ease of dynamic languages like Python.
• Although it is a language designed for system programming, it provides a garbage collector, reflection and other high-level capabilities that make it a very powerful language.

Therefore we are talking about a robust, technical and efficient language. So, let us install Go language on CentOS 8.

Install GO language on Rocky Linux 8 / CentOS 8 / Fedora 34

First you have to update the system. This is always recommended for security reasons.

So open a terminal session and run the following:

:~$ su
:~# dnf update

By having the system updated, you will have the latest security patches available and your system will be more robust.

Then you have to download the corresponding binaries for our system. For this we will use a tool called wget, if you don’t have it installed, you will have to do it.

:~# dnf install wget
:~# wget https://dl.google.com/go/go1.13.1.linux-amd64.tar.gz

Versions may change over time. So check in the download section which is the latest stable version and modify the command.

Now we will have to unzip it and move it to an installation folder. In my case, I will do it in /usr/local and unzip the file there.

:~# dnf install tar
:~# tar -zxvf go1.13.1.linux-amd64.tar.gz -C /usr/local

It is now the turn to maintain the environment variables. All this so that the installation does not have problems finding the command and the compiler.

:~# echo 'export GOROOT=/usr/local/go' | tee -a /etc/profile
:~# echo 'export PATH=$PATH:/usr/local/go/bin' | tee -a /etc/profile

Finally, refresh your bash profile.

:~# source /etc/profile

Now let’s test the installation. To do this we will create the typical Hello World program. First create the folders:

:~# mkdir -p project/helloworld
:~# cd project/helloworld

Then, create the new file and add the following:

:~# nano helloworld.go

package main
import "fmt"
func main() {
    fmt.Printf("Hi, I am Angelo. Welcome to osradar.com\n")
}

Then, save the changes and close the file.

Now, run the program:

:~# go run helloworld.go

Yeah, everything’s fine and working. Now you can start creating great apps with Go.

Conclusion

Go is a versatile and very efficient modern programming language sponsored by Google. This makes it quite robust with a solid community behind it. Today you have learned to install it on CentOS 8 and RHEL 8.
