1. Introduction to Golang

Golang, also known as the Go language, is an open source, efficient programming language developed by Google and first released in 2009. Golang is a statically typed programming language characterized by efficiency, security, concurrency and maintainability.

With the rise of cloud computing, big data and other technologies, Golang has become a very popular language in the industry due to its high concurrency and efficiency, especially in network programming, distributed systems, cloud computing and other fields. It is widely used and has become one of the technology choices for many enterprises.

This article will introduce how to compile and deploy Golang programs.

2. Compilation of Golang

Compilation of Golang is very simple. It only requires writing a complete code file and compiling it using the Golang compiler. Before starting to write code, you need to confirm that the Golang compilation environment is installed and the corresponding environment variables are configured.

Golang’s code files require .go as the suffix. After writing the code, we can execute the following command in the terminal to compile:

go build example.go
Copy after login

This command will compile the required related dependencies and generate binary files. If there are no errors in your code, an executable file named example will be generated after successful compilation.

In addition, Golang's compiler also provides the function of cross-compilation, that is, it can be compiled on one platform to generate a program that is executable on another platform. For example, you can compile an executable file under Windows on the Linux platform, and you only need to specify the corresponding platform when compiling.

The following is an example of cross-platform compilation:

GOOS=windows GOARCH=386 go build example.go
Copy after login

This command will compile on the Linux platform and generate an executable file under the Windows x86 platform.

3. Deployment of Golang

The deployment of Golang is basically the same as the deployment of other programming languages. It mainly involves setting up the server environment, uploading binary files and starting the program.

  1. Server environment construction

Compared with other languages, Golang programs are compiled into binary files and do not need to rely on other libraries when running. Therefore, Golang deploys The environment is relatively simple. You only need to install a Golang operating environment on the target server.

Golang’s operating environment can download the corresponding version of the binary file from the official website. When installing on a Linux system, you only need to add it to the system’s $PATH environment variable:

export PATH=$PATH:/usr/local/go/bin
Copy after login
  1. Upload binary file

After successful compilation, an executable file named example will be generated. Upload this file to any directory on the target server, such as /home/user/example.

  1. Start the Golang program

Enter the directory where the executable file is located on the target server and execute the following command to start the program:

./example
Copy after login

This command will pass the compiled executable file example as a parameter to the operating system kernel to start the Golang program.

4. Summary

The compilation and deployment of Golang are very simple, require less preparation work, and the coding efficiency and operating efficiency are very high. For some high-performance, high-concurrency, and easy-maintenance scenarios, Golang is a good choice. Of course, Golang's ecosystem is still growing, and more and more developers are joining it every day. I believe that its application scope will continue to expand in the near future.
