In this article, we will see how to build a distributed cache system from scratch, this is the first part of our articles.

set the basic environment

#

First of all, let’s simply create a folder to store the new project, the command should look like this: mkdir cache.

you should start a new go project with go mod init something, for example: go mod init cacheme, then you can find a go.mod file that appears in your directory.

Since we have a project, we can create a main.go file in our project to print hello, world:

package main

import "fmt"

func main() {
	fmt.Println("vim-go")
}

Now, it’s time to run the project with go run main.go, you can also compile it to a binary with go build -o hello main.go and input ./hello to run this binary executable file.

the other things we could do (but not necessary) are listed as follows:

• add a .gitignore file so that we can ignore some useless files like .DS_Store in mac environment
• add a read me so that everyone else can understand what this project is used for.
• add a license, I personally prefer some simple licenses like MIT or GPL3
