Get Going with Go and Redis

Get Going with Go and Redis

gopherGo is a promising language. It's a strong replacement for Java, it's similarly productive to writing Python, and it is an excellent tool for writing servers.

I'm starting to dive into it in my spare time, and in this blog post I will show you the basics of getting started with Go and Redis together. This tutorial assumes you're running a flavor of Mac OS X and are comfortable with Terminal.


Install Redis

Run the following commands on most *nix command lines to download, unpack and install Redis: wget tar xvzf redis-stable.tar.gz cd redis-stable make sudo make install

Install Go

Install Go. As of writing, this was the latest version for Mac.

(You can find the list of all available downloads by clicking from the go download page.)

Install Mercurial

You must have Mercurial installed for the go get command to work. So let's install Mercurial, which is super easy if you manage packages with Homebrew.

brew update brew doctor brew install mercurial


Create your go workspace. This is just the way go works. Do the following: mkdir gocode

Open up .bashrc (or .zshrc if using zsh): vim .bashrc

On the last line set the GOPATH: export GOPATH="$HOME/gocode"

Create your project workspace

Now, we can create our project workspace.

cd gocode mkdir -p src/

Let's Code

Cool, now let's create the redis go project.

Create the hello-go-redis project

cd src/github/yourusername mkdir hello-go-redis cd hello-go-redis vim hello-go-redis.go

Paste the following into hello-go-redis.go.

package main

import "fmt" import ""

func main() { //INIT OMIT c, err := redis.Dial("tcp", ":6379") if err != nil { panic(err) } defer c.Close()

//set c.Do("SET", "message1", "Hello World")

//get world, err := redis.String(c.Do("GET", "message1")) if err != nil { fmt.Println("key not found") }

fmt.Println(world) //ENDINIT OMIT }

Get redis.

go get

Run it

/usr/local/bin/redis-server go run hello-go-redis.go

You will get the message back "Hello World." Nice job, you just wrote your first Go script. Check out further tutorials on the Go site.
