Pagoda panel installation golang

Preface

Golang is a programming language developed by Google. It has the characteristics of cross-platform, multi-threading, lightweight and is widely used in network programming, cloud computing, big data analysis and other fields. . In order to use Golang to develop applications on the server, you need to install the Golang environment first. This article will introduce how to install the Golang environment on the Pagoda panel.

Step 1: Download Golang

1. Open the Golang official website (https://golang.google.cn/dl/), select the corresponding system version to download Golang.

2. You can also choose other download methods. You can download the tgz compressed package or compile and install

Step 2: Unzip and install Golang

1. Will download the Golang Upload compressed files to the server in the following ways:

(1) Upload files through the file manager of the Pagoda panel

(2) Use FTP, SCP and other tools to upload files

2. Unzip the Golang compressed file, and then enter the directory to install.

You can use the following command:

tar -C /usr/local -xzf go1.xx.x.$os-$arch.tar.gz

3. Settings Environment variables enable the system to find Golang.

You can use the following command:

echo 'export PATH=$PATH:/usr/local/go/bin' >> ~/.bashrc

source ~ /.bashrc

4. Verify whether the installation is successful.

You can use the following command:

go version

If the Golang version information appears, it means that Golang has been successfully installed.

Step 3: Configure Golang environment

You can use the following command:

go get -u github.com/kardianos/govendor

Step 4: Test whether Golang is available

1. Create And run the Golang Hello World program.

You can use the following command:

mkdir /home/go/src/hello

echo 'package main

import "fmt"

func main() {

fmt.Println("Hello, world.")

}' > /home/go/src/hello/hello.go

go run /home/go/src/hello/hello.go

2. Browser access the Golang program

If the access is successful, it means that Golang has been started successfully.

Summary

Through the above steps, we successfully installed the Golang environment on the Pagoda panel and completed the configuration and testing of the environment. Next, we can start developing applications using Golang!
