How to successfully deploy Golang projects online

Golang is an open source programming language designed and developed by Google. In recent years, with the development of Internet technology, Golang is used by more and more developers, and online deployment is also a part that needs attention. In this article, I will introduce how to successfully deploy a Golang project online.

1. Write code

After you complete the Golang project development, you can publish it online. Before doing this, make sure the code is organized and packaged in an executable binary.

For example, you can package your code into a binary using the following command:

$ go build -o myapp main.go

This command will build an executable binary named "myapp" using your code.

At this point, you have completed the preparation of the local development environment. The following describes how to deploy the code on an online server.

2. Select the server

Before selecting the server, you need to consider the following factors:

1. The operating system of the server

Golang can run on multiple operating systems, including Linux, macOS and Windows. Therefore, you can choose the operating system that suits your project.

2. Hardware configuration of the server

The hardware configuration of the server determines the performance of the server, including CPU, memory, storage, etc. You need to choose the appropriate hardware configuration based on your project needs.

3. The server’s network connection

The server’s network connection has a great impact on the access speed. Therefore, you need to choose a server with a good network connection.

After selecting the server, you need to connect to the server using ssh.

3. Deploy code

First, create a new directory on the server to store your Golang code.

$ mkdir myapp && cd myapp

Then, copy the code you wrote in the local development environment to this directory.

Next, you need to use the scp command to transfer the executable file to the server.

$ scp ./myapp user@server:/home/user/myapp

This command will upload the myapp file to the server's /home/user/myapp directory.

Next, you need to use ssh to connect to the server and give the file executable permissions.

$ chmod +x myapp

Now you can run your Golang code on the server using the following command:

$ ./myapp

Four. Configure the reverse proxy

If your Golang project needs to listen HTTP request and return a response to the client, you need to install a reverse proxy on the online server. A reverse proxy provides an interface for clients and Golang applications so that they can communicate with each other.

On Linux, you can use Nginx as a reverse proxy. First, install Nginx.

$ sudo apt-get install nginx

Then, use the following command to create a new server block.

$ sudo nano /etc/nginx/sites-available/myapp

Add the following configuration to the myapp file.

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://localhost: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 listen to port 80 for HTTP requests and proxy the request to the local port 8080.

Next, you need to enable this configuration and restart Nginx.

$ sudo ln -s /etc/nginx/sites-available/myapp /etc/nginx/sites-enabled/
$ sudo service nginx restart

Now you can run your Golang application on the server and receive HTTP requests through the reverse proxy using the following command:

$ ./myapp

In this article, we have introduced how to deploy Golang code Go to an online server and use Nginx as a reverse proxy. With the right configuration and optimization, you can achieve excellent performance and reliable scalability.
