vps deploy golang environment

With the rapid development of the Internet, more and more people are paying attention to server application development under Linux systems, and Golang, as a high-performance programming language, has received more and more attention. So, how to deploy Golang environment on VPS? This article will introduce this issue in detail.

1. Install Golang

To install Golang on VPS, you need to download the binary installation package first. You can download the corresponding installation package from the Golang official website (https://golang.org/dl/), or use the following command to download:

$ wget https://golang.org/dl/go1.16.4.linux-amd64.tar.gz

After the download is complete, unzip the file:

$ tar -xzvf go1.16.4.linux-amd64.tar.gz

Move the decompressed folder to the /usr/local directory:

$ sudo mv go /usr/local/

2. Configure environment variables

In order to use the Go command in any directory, you need to add the Golang path to the environment in variables. Edit the bashrc file:

$ sudo nano ~/.bashrc

Add the following content at the end of the file:

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

Among them, $GOROOT is the Golang installation path, $GOPATH is the customized working directory, and $PATH contains the current system's path.

After saving the file, execute the following command to update the environment variables:

$ source ~/.bashrc

After changing the settings, you can verify whether the settings are successful by using the following command:

$ go version

If successful, it will Output version number:

$ go version go1.16.4 linux/amd64

3. Test environment

In order to verify whether the Golang environment is working properly, you can create a simple Hello World program. Execute the following command:

$ nano hello.go

Enter the following code in the editor:

package main

import "fmt"

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

After saving and exiting the file, use the following command to compile the program:

$ go build hello.go

The generated binary file will will be in the same directory. Now you can run the program through the following command:

$ ./hello

The program will output the following content:

Hello, World!

At this point, we have successfully deployed the Golang environment and successfully compiled and executed a simple program.

4. Summary

In this article, we learned how to deploy the Golang environment on VPS, installed Golang, configured environment variables, and tested whether the environment is working properly. Through the above steps, we can develop Golang applications on VPS and get better experience and results in web development, cloud computing and other fields.
