Test Go installation on CentOS 8 / RHEL 8

Now that we have Go installed on RHEL 8, let’s test to ensure it is working.

Start by creating your workspace directory.

mkdir $HOME/go

Create a directory inside it to host a test Go application.

cd $HOME/go
mkdir -p src/helloworld
cd src/helloworld

Create a file named helloworld.go that looks like:

tee helloworld.go<<EOF
package main
import "fmt"
func main() {
	fmt.Printf("hello, worldn")
}
EOF

Build the application with go tool

go build

This will generate a new file called helloworld .

$ ls
helloworld  helloworld.go

Execute the file by running.

$ ./helloworld 
hello, world

To install the binary into your workspace’s bin directory, use:

$ go install
$ ls ~/go/bin/
helloworld

To remove it use:

go clean -i

You can add your Go binary directory to $PATH.

$ vim ~/.bashrc 
export PATH="$PATH:~/go/bin/"

You have installed Go on RHEL 8 / CentOS 8. Enjoy developing Go applications on your RHEL workstation.
