centos 7 deployment golang

Go is a new, powerful and simple programming language with good memory safety, concurrency and code maintainability. If you are using CentOS 7 and need to deploy golang on your server, this article will provide you with detailed step-by-step guidance.

Step 1: Install Golang
First, we need to install the Go compiler on CentOS 7.

Go officially provides an installation package for Linux. You can directly download the latest version of the installation package from the official website for installation. Here I used the yum command to install, the command is as follows:

sudo yum install golang

After running the above command, please wait for the installation process to complete.

After the installation is complete, you also need to set some environment variables so that you can use Go correctly. These environment variables include GOPATH, GOROOT, and PATH.

GOPATH: The Go compiler will automatically look for src, bin and pkg under this environment variable to store source code, executable files and compiled packages.
GOROOT: Go installation directory. If you use yum to install, you can set GOROOT to /usr/lib/golang.
PATH: To facilitate the use of Go commands, please add $GOPATH/bin and $GOROOT/bin to the PATH environment variable.

Edit the /etc/profile file and add the following configuration:

export GOPATH=/opt/go
export GOROOT=/usr/lib/golang
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

After saving, execute the following command to take effect:

source /etc/profile

Step 2: Write the first Go program

After the installation is complete, we can use a simple program to test the working status of Go. Enter the following command in the terminal to create a new Go project directory:

mkdir goproject
cd goproject
mkdir src
mkdir pkg
mkdir bin

Next, write a simple HelloWorld code as follows:

package main

import (
    "fmt"
)

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

Save the code as hello.go, and then Use the following command to compile:

go build hello.go

Run the compiled executable file:

./hello

If you see the output of "Hello, World!", then congratulations, you have successfully Golang is deployed on CentOS 7!

Summary

The above are the steps to deploy golang on CentOS 7. The installation and configuration are very simple. If you need to start using golang for project development, it is recommended that you read the official documentation to learn more about the language. Happy programming!
