Detailed introduction to the steps and methods of golang server deployment

With the popularization of the Internet and the rapid development of technology, more and more companies have begun to get involved in the Internet field, and the server side of the Internet has become the focus of most attention for companies. In recent years, golang, as an efficient and reliable programming language, has been favored by more and more enterprises and developers, becoming the preferred language for server-side development. So, in this case, how to deploy the golang server quickly and effectively? This article will introduce in detail the steps and methods of golang server deployment.

1. Install golang

Before you start deploying the golang server, you first need to install golang. The method to install golang is very simple. You only need to go to the official website (https://golang.org/dl/) to download the corresponding installation package and then install it. If you are using a Linux system, you can also install golang through the package manager. After the installation is complete, you can enter go version through the command line to verify whether the installation is successful.

2. Write code

Before deploying golang server, you need to write the corresponding code first. Here we take a simple HTTP server as an example:

package main

import (
    "fmt"
    "net/http"
)

func hello(w http.ResponseWriter, req *http.Request) {
    fmt.Fprintf(w, "hello, world\n")
}

func main() {
    http.HandleFunc("/hello", hello)

    err := http.ListenAndServe(":8080", nil)
    if err != nil {
        panic(err)
    }
}

The above code implements a simple HTTP server. When accessing http://localhost:8080/hello, Will return hello, world.

If you need to deploy a more complex server, please refer to golang official documentation (https://golang.org/doc/) or other related books.

3. Compile the code

After completing the server-side code writing, the code needs to be compiled to generate an executable file. Enter the project directory and execute the following command:

go build -o server

After executing the above command, an executable file named server will be generated in the current directory.

4. Deploy the server

After completing the code compilation, the executable file needs to be deployed to the server. Executable files can be uploaded to the server using tools such as FTP, SCP, rsync, etc. Here we take deployment using the rsync tool as an example:

rsync -zpv server user@server-ip:/home/user/server/

The above command uploads the executable file server to the remote server /home/user/server/ directory.

5. Start the server

After completing the file deployment on the server, you need to start the server on the server. You can use the screen command to start the server process and put the process to run in the background:

screen -dmS server ./server

The above command starts a screen session named server and starts the server process in the session./server.

6. Test the server

After the server is started, you can use the curl command to test:

curl http://server-ip:8080/hello

The above command will request http://server- ip:8080/hello, and return the data returned by the server.

7. Summary

Through the above steps, we have successfully deployed a simple golang server to the server and tested it. Of course, this is just a simple example. In the actual deployment process, a series of operations and optimizations may be required, such as Nginx configuration, code optimization, etc., to achieve better performance and user experience.
