Detailed introduction on how to deploy Golang project to domain name

Golang is an open source, fast and efficient programming language that is currently widely used in the field of Internet development. After development is completed, it is very necessary to deploy the Golang project to the domain name. Therefore, this article will introduce how to deploy the Golang project to a domain name.

1. Understand the Golang project

Before we start deploying the Golang project, we need to have a sufficient understanding of the project itself. Understanding the project source code, folder structure, dependent packages, etc. can help us better deal with problems that may be encountered during the deployment process.

2. Use Nginx reverse proxy

Nginx is a popular web server software that can forward between multiple domain names listening on the same IP address and port ask. This allows multiple virtual hosts to be served from a single IP address. Using Nginx reverse proxy, requests can be forwarded to the listening port of the Golang project through Nginx, thereby realizing domain name deployment.

First, install Nginx and add the following location in the configuration file:

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;
}

This configuration will cause Nginx to listen for requests to access the root path and forward them to the local 8080 port.

3. Use Gunicorn to deploy Golang

Gunicorn is a WSGI HTTP server based on Python that uses a multi-process approach to handle requests. Although Gunicorn is a Python project, it is quite compatible with Golang deployment. Golang projects can be deployed on domain names through Gunicorn.

First, install Gunicorn and start the Golang project using the following command:

gunicorn --bind 127.0.0.1:8080 main:app

This command will start a Gunicorn server, listen to the local 8080 port, and forward the request to the app function of the main file.

4. Use systemd to operate and maintain Golang

Systemd is a system and service manager for Linux systems. It can run a series of services when the system starts and try to restart these services when there is a problem. Systemd can better manage the running of Golang projects.

First, create a systemd unit file and add the following content:

[Unit]
Description=Golang Application

[Service]
ExecStart=/usr/bin/gunicorn --bind 127.0.0.1:8080 main:app
User=root
Group=root
WorkingDirectory=/opt/golang-project
Restart=always

[Install]
WantedBy=multi-user.target

This file describes the name, running mode, working directory and other information of the Golang project. Then use the following command to start the systemd service:

sudo systemctl start my-golang-app

This command will start a service named "my-golang-app". In order to have this service start automatically when the system starts, you can use the following command:

sudo systemctl enable my-golang-app

Summary

This article details how to deploy the Golang project to a domain name, including using Nginx reverse proxy, Use Gunicorn, use Systemd for operation and maintenance management, etc. Through these methods, we can better manage and deploy Golang projects, fully explore the advantages of Golang in practical applications, and improve development efficiency and web service performance.
