How To Install Go On CentOS 7.
In this tutorial, we will show you how to download and install Go on a CentOS 7 system.
Go, often referred to as golang is a modern open-source programming language created by Google. Many popular applications, including Kubernetes, Docker, Hugo, and Caddy are written in Go.
How to Install Go
At the time of writing this article, the latest stable version of Go is version 1.13. Before downloading the tarball, visit the official Go downloads page and check if there is a new version available.
Follow the steps below to install Go on CentOS 7:
Download the tarball.
To download the Go binary use either wget or curl :
Verify the tarball.
Once the download is completed verify the tarball checksum with the sha256sum command:
Extract the tarball.
Use the tar command to extract the tarball to the /usr/local directory:
Adjust the Path Variable.
Now we need to tell our system where to find the Go executable binaries by adjusting the $PATH environment variable.
We can do this by appending the following line to the /etc/profile file (for a system-wide installation) or to the $HOME/.bash_profile file (for a current user installation):
Save the file, and load the new PATH environment variable into the current shell session with the following command:
Test the Installation
To test whether Go is installed correctly, we will set up a workspace and build a simple “Hello world” program.
Create the workspace directory
By default the workspace directory is set to $HOME/go, to create it type:
Create a simple “Hello World” Go file.
Inside the workspace create a new directory src/hello
and in that directory create a file named hello.go

Build the hello.go file:
To build the file, switch to the ~/go/src/hello directory and run go build:
The command above will build an executable named hello.
Run the executable:
Run the executable by typing:
If you see the output above, then you have successfully installed Go.
Now that you have downloaded and installed Go on your CentOS system, you can start developing your Go projects.
