Pagoda deployment golang web

In today's Internet era, the demand for web applications is growing day by day. How to quickly deploy and manage web applications has become a common concern for developers and operation and maintenance personnel. Pagoda panel is a server management panel that integrates multiple functions. It can help developers and operation and maintenance personnel deploy web applications quickly and easily. This article will introduce how to deploy golang web applications through pagoda.

1. Environment preparation

1. Install the Pagoda panel

You need to install the Pagoda panel. You can download the latest version of the panel from the official website for installation, or you can use wget command to install.

2. Install golang

In CentOS system, you can use the yum command to install golang

yum install golang

After the installation is complete, you can use the following command to confirm whether golang is installed Success

go version

3. Install Git

Git is a distributed version control system. In order to easily obtain the golang web application source code, installing Git is necessary.

In CentOS, you can install Git through yum

yum install git

2. Deploy golang web application

1. Write golang web application

First you need to write a golang web application. In this example, we use a simple "Hello World" as the sample code. The code is as follows:

package main

import (
    "fmt"
    "net/http"
)

func hello(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Hello, World!")
}

func main() {
    http.HandleFunc("/", hello)
    err := http.ListenAndServe(":8080", nil)
    if err != nil {
        panic(err)
    }
}

The above code defines a route/hello and returns the "Hello, World!" string.

2. Deploy the application to the server

On the local computer, use the git command to upload the code to github, and then on the server, use the git clone command to upload the code Pull it down

git clone https://github.com/xxx/xx.git

After pulling it down, switch to the code directory and use the go build command to compile the executable file.

go build -o app main.go

After the compilation is completed, we can test whether it can run normally through the following command.

./app

Access http://server ip address:8080 in the browser, you can see the string output of "Hello, World!"

3. Configuring Nginx reverse proxy

In order to make access more secure and convenient, we need to use Nginx reverse proxy. Edit the nginx.conf file and add the following configuration.

server {
    listen 80;
    server_name example.com;
    location / {
        proxy_pass http://127.0.0.1:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

The above configuration tells Nginx to listen on port 80 and proxy all HTTP requests to the local port 8080. Nginx sends the HTTP request to the specified service and carries the HTTP protocol header information to ensure that the target address can return data correctly.

4. Access golang web application

After completing the above steps, we successfully deployed the golang web application. Enter the domain name or IP address into the browser to access the web application.

Summary

This article introduces how to deploy golang web applications through Pagoda. We introduced the steps of environment preparation, deploying golang web application, configuring Nginx reverse proxy and accessing golang web application. Through the introduction of this article, I believe that readers have a deeper understanding of the deployment of golang web applications, and I hope it will be helpful to readers in their work and study.
