How to install golang using yum

This article introduces how to install golang in yum.

Golang is a programming language developed by Google and is mainly used to build efficient, reliable and simple software. Golang has a simple and easy-to-learn syntax, a garbage collector, and supports concurrency and multi-core operations. It is a very popular language.

Installing Golang in a Linux system requires a series of operations, but installing through yum can greatly simplify the process and make the installation of Golang faster and more convenient. Let's take a look at the steps to install Golang on yum.

Step 1: Add Epel source

First we need to add Epel source to obtain the installation package of the Golang program. Epel source is a project that provides additional packages to the community for RHEL, CentOS and Scientific Linux. Therefore, if your system does not have the Epel source installed, you will need to add it first.

Use the following command to add the Epel source:

sudo yum install epel-release

Step 2: Install the Golang program

After adding the Epel source, we can start installing the Golang program. The latest version of Golang program can be easily installed through yum.

Use the following command to install Golang:

sudo yum install golang

After the command is executed, the system will download and install the Golang program. After the installation is complete, you can use the following command to verify:

go version

If the Golang version information appears in the returned result, the installation is successful.

Step 3: Configure Golang environment variables

After you install the Golang program, you also need to configure environment variables to let the operating system know its existence. An environment variable is a configuration used by the operating system to tell it where to look for executable files, library files, etc.

Before configuring environment variables, you first need to create a working directory. You can create a directory named "go" using the following command:

mkdir ~/go

Next, edit the environment variables with the following command:

sudo nano /etc/profile

Add the following lines of environment variables at the end of the file:

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

Save and exit the file. Then execute the following command to make the environment variables take effect:

source /etc/profile

At this point, you have successfully configured Golang’s environment variables.

Step 4: Hello World

Finally, let’s test whether Golang can work properly. You can use the following line of code to print "Hello World":

package main

import "fmt"

func main() {
    fmt.Println("Hello World")
}

Save the code as "hello.go", and then you can use the following command to run the program:

go run hello.go

If the output in the console "Hello World" means that Golang has successfully worked.

Summary

With this simple step, we can easily install and configure Golang on yum. This allows you to develop a variety of applications using the language more quickly.
