Golang Introduction

Golang is an open-source project aimed at improving programmer productivity.

Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that make full use of multi-core and networked machines, while its novel type system enables flexible and modular program construction.

Go can quickly compile to machine code while also having the convenience of garbage collection and the powerful functionality of runtime reflection. It is a fast, statically typed compiled language that feels like a dynamically typed interpreted language.

Golang Installation

info

The mirror site provides installation packages for Golang on four platforms: Linux/Windows/Mac/FreeBSD. Please download the installation package corresponding to your system.

   # use curl
   curl -O https://mirrors.hust.edu.cn/golang/go<version>.linux-<arch>.tar.gz

2. After downloading, if Golang was previously installed, execute the following command to remove it:

   Whether root user

   sudo rm -rf /usr/local/go

   sudo tar -C /usr/local -xzf go<version>.linux-<arch>.tar.gz

4. Add the Golang executable file path to the environment variable PATH:

   # Only effective for current terminal
   export PATH=$PATH:/usr/local/go/bin
   # Long-term effective
   echo 'export PATH=$PATH:/usr/local/go/bin' >> ~/.zshrc # If using zsh
   echo 'export PATH=$PATH:/usr/local/go/bin' >> ~/.bashrc # If using bash

5. Verify installation, open a new terminal and enter:
