Analysis of Go language installation steps on Linux platform

Installing Go language on Linux platform is the first step in Go programming. Only if Go is installed correctly can it go smoothly. carry out development work. This article will introduce in detail the steps to install the Go language under a Linux system, with specific code examples for reference.

Step one: Download the Go language installation package

First, we need to go to the Go official website (https://golang.org/dl/) to download the Go language installation package under the Linux platform . Choose the version suitable for your system to download, such as amd64 (64-bit system) or 386 (32-bit system).

wget https://golang.org/dl/go1.17.2.linux-amd64.tar.gz

Step 2: Decompress the installation package and configure environment variables

After the download is completed, we will decompress the downloaded installation package to the specified directory (such as /usr/local) and set the corresponding environment variable.

tar -C /usr/local -xzf go1.17.2.linux-amd64.tar.gz
echo "export PATH=$PATH:/usr/local/go/bin" >> ~/.profile
source ~/.profile

Step 3: Verify the installation results

After the installation is completed, we can verify whether Go is successfully installed through a simple command.

go version

If the Go version number can be displayed normally, it means that the Go language has been successfully installed in your Linux system.

Step 4: Edit the Go programming environment

In order to make Go programming more convenient, we can set two environment variables, GOPATH and GOROOT, in the system.

echo "export GOPATH=$HOME/go" >> ~/.profile
echo "export GOROOT=/usr/local/go" >> ~/.profile
source ~/.profile

Step 5: Create the Go project directory

Now that we have successfully installed Go and configured the corresponding environment variables, we can create a Go project and start writing code .

mkdir -p $HOME/go/src/hello
cd $HOME/go/src/hello

Step 6: Write the first Go program

Next, we can use any text editor to create a simple Go program, such as hello.go, with the following content:

package main

import "fmt"

func main() {
    fmt.Println("Hello, Go!")
}

After saving and closing the editor, we can use the following command to compile and run the program:

go run hello.go

If you can see the output "Hello, Go!", it means you have successfully installed Go language and be able to compile and run the code correctly.

Summary:

Through the above steps, we successfully installed the Go language under the Linux platform and wrote a simple Hello World program for verification. I hope this article can help beginners install and use the Go language on Linux systems. If you encounter any problems or questions, you are welcome to consult and ask questions at any time. I hope you will succeed in learning the Go language!
