How to configure the environment under Linux to support Go language development?

Configuring the environment under Linux to support Go language development is a very important step. This article will introduce how to configure the Go language development environment in Linux systems and provide specific code examples.

Step 1: Install the Go language environment

1. Open the terminal and enter the following command to download the Go language installation package:

   wget https://golang.org/dl/go1.17.1.linux-amd64.tar.gz

2. Unzip the installation package and set the environment variables:

   sudo tar -C /usr/local -xzf go1.17.1.linux-amd64.tar.gz
   export PATH=$PATH:/usr/local/go/bin

3. Verify whether the Go language is successfully installed:

   go version

Step 2: Configure GOPATH

1. Create a working directory to store Go language project files:

   mkdir ~/go_projects

2. Set the GOPATH environment variable and edit ~/.bashrc file and add the following content:

   export GOPATH=$HOME/go_projects
   export PATH=$PATH:$GOPATH/bin

3. Update the environment variable configuration:

   source ~/.bashrc

Step 3: Create and run the Go language program

1. Create a new Go language project under GOPATH:

   mkdir ~/go_projects/src/hello

2. Write a simple Hello World program and create a new hello.go file and enter the following content:

   package main
   
   import "fmt"
   
   func main() {
       fmt.Println("Hello, World!")
   }

3. Compile and run the program:

   go run hello.go

Step 4: Install the Go language package management tool

1. Install Go language package management toolgo mod：

   go get -v github.com/golang/protobuf/protoc-gen-go

2. Use go mod for package management:

   go mod init example.com/hello
