vps build golang

With the development of the Internet, more and more people are beginning to get involved in the field of Internet development. Among them, the programming language golang has gradually become favored by developers because of its efficient concurrency mechanism and concise syntax. When using golang for development, we need to have a reliable operating environment, which requires the use of VPS to build it. This article will introduce how to set up a golang development environment on VPS, hoping to be helpful to developers in need.

1. Choose VPS

Before we start building the golang environment, we need to choose a suitable VPS first. VPS is the abbreviation of Virtual Private Server, that is, virtual private server. VPS virtualizes multiple independent servers on one computer and can run different operating systems and software independently. Therefore, we can build the environment we need on VPS, such as golang environment. When choosing a VPS, we need to consider the following points:

1. Price: The price of a VPS varies due to its performance and configuration, and we can choose a suitable price according to our needs.
2. Stability: We need to choose a stable and reliable VPS to ensure the normal progress of development and operation and maintenance.
3. Server location: We need to choose a server that is closer to the area where our users are located to improve access speed and efficiency.

After selecting the appropriate VPS, you can start setting up the golang development environment.

2. Install golang

Before setting up the golang environment, we need to install golang first. Under Linux systems, we can install golang directly through the package manager. Taking Ubuntu as an example, we can install it through the following command:

sudo apt update
sudo apt install golang

After the installation is completed, we can verify it through the following command:

go version

If the golang version information is output, it means the installation has been successful. .

3. Configure the golang environment

After installing golang, we need to configure the golang environment variables. Under Linux system, we can proceed through the following steps:

1. Open the bashrc file:

vim ~/.bashrc

2. Add the following code at the end of the file:

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

Among them, GOPATH is the working directory of golang, which can be specified by yourself. We can verify whether the configuration takes effect through the following command:

source ~/.bashrc
go env

If the correct golang environment information is output, the configuration is successful.

4. Use golang

After the installation and configuration are completed, we can use golang for development. We can create a golang project through the following command:

mkdir $GOPATH/src/example
cd $GOPATH/src/example

Then, we can create a hello world program with the file name main.go and the following content:

package main

import "fmt"

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

We can compile and Run the program:

go build
./example

If "Hello, world." is output, it means the operation is successful.

5. Summary

This article introduces the steps to build a golang development environment on VPS, including selecting VPS, installing golang, configuring the golang environment and using golang. Through these steps, we can quickly build our own golang development environment on the VPS to facilitate development and deployment. I hope this article can be helpful to developers in need.
