How To Install Go and Revel on an Ubuntu 13.04 x64 VPS


In this tutorial, we're going to download and install the latest version of Go and the latest version of the Revel web framework on top of that. In case you're not familiar with Revel, here's a snippet about the framework from their website:

A high productivity web framework for the Go language, in the spirit of Rails and Play!

Revel really does focus on programmer productivity. It can handle a lot of the usual stumbling blocks for creating solid web applications (routing, validation, templating, caching, etc.) for you, leaving you to focus on building a lean application quickly. "So," I (almost) hear you cry, "How's it any different from Rails?" Well for starters, it's fast. Very fast. It uses the Go HTTP server, which has been tested to serve requests three to ten times as fast as Rails. Other benchmarks conclude similarly. It's also a great way to learn Go.

If you're not already familiar with Go, there's a quote on the website that sums it up pretty effectively:

Go is an open source programming environment that makes it easy to build simple, reliable, and efficient software.

Go is developed by some very clever people at Google (including Ken Thompson, designer of the UNIX operating system and all-round Computer Science champion). They're already using it for a number of internal products and services, including their newly revamped dl.google.com. In a nutshell, it's a language with power that's closing in on C, with a (relatively) high-level syntax like most modern scripting languages.

Step 1: Create the Virtual Private Server

In this tutorial, I'll be using an Ubuntu 13.04 x64 cloud server.

Go ahead and create the VPS. Once it's done, SSH in.

Step 2: Setting Up a User

The first thing we're going to do is set up a user account as we'll be keeping the go binaries and our working directory within our user's home directory. For the steps in this section, replace USER with your own username.

First, we're going to create the user and set a password:

sudo useradd -m -d /home/USER -s /bin/bash -U USER
passwd USER

Next, we're going to add our user to the admin group to grant superuser privileges:

groupadd admin && usermod -a -G admin USER

Finally, we're going to login and change to our home directory:

cd ~/

Step 3: Installing Go

Currently, aptitude is a little behind the most recent release of Go (1.02 vs 1.1). We're going to download and install Go from the latest package on Google Code.

First, we need to update aptitude and grab git:

sudo apt-get update
sudo apt-get install git mercurial

Next, we're going to download Go:

wget http://go.googlecode.com/files/go1.3.3.linux-amd64.tar.gz
tar xf go1.3.3.linux-amd64.tar.gz
rm go1.3.3.linux-amd64.tar.gz

We now need to add some environment variables to our .profile to define where our Go installation lives:

echo "export GOROOT=\$HOME/go" >> ~/.profile
echo "PATH=$PATH:\$GOROOT/bin" >> ~/.profile
source ~/.profile

You should now be able to see the currently installed version of Go:

go version

We can now set up our Go path. This is the folder (or set of folders) specified by the GOPATH environment variable. It's important to note that this cannot be the same as the GOROOT variable, which specifies where our Go installation itself lives.

The Go documentation refers to the GOPATH variable as:

a colon-separated list of paths inside which Go code, package objects, and executables may be found.

In this tutorial, we'll only be using one GOPATH directory; ~/gocode. This will be where we store the source for the Revel framework, its dependencies, and the example chat app that we will run in this tutorial. Our GOPATH directory will also store the binaries for these packages. For more information on the purpose and structure of the GOPATH variable, there's a full explanation in the documentation.

Let's create the directory and add some more environment variables to our .profile:

mkdir ~/gocode
echo "export GOPATH=\$HOME/gocode" >> ~/.profile
echo "PATH=\$PATH:\$GOPATH/bin" >> ~/.profile
source ~/.profile

We're now ready to download and install Revel.

Step 4: Installing Revel

This section serves as a great demonstration of Go's go get command:

go get github.com/revel/cmd/revel

That's it! We can now test out our Revel installation by running the example chat app that comes with the installation:

revel run github.com/revel/revel/samples/chat

After a (very) short while, it should tell you that it's Listening on :9000 and Running revel server. This means we're ready to check out our chat app in the browser. Visiting http://YOUR.VPS.IP.HERE:9000 will let you log in and start chatting away!

Addendum: Rebuilding Revel

The Revel framework changes daily, so it's important to know how to rebuild it when we need to. Firstly, pull the latest changes from the remote repository:

cd $GOPATH/src/github.com/robfig/revel
git checkout master
git pull origin master

Now we can rebuild the binary:

cd $GOPATH/bin
rm revel
go install -v github.com/robfig/revel

This will reinstall Revel from your local source, held in $GOPATH/src/github.com/robfig/revel.


The documentation has a solid collection of resources available to get you started with Revel. If you'd like to know more about how the chat app is implemented, they've got a full rundown on their website.

download go: https://golang.com/dl/go1.4.2.linux-amd64.tar.gz [or whatever version you want] revel is at https://www.github.com/revel/revel/

of course link changes are to be expected. great write up though!!


As of right now, IP addresses on UK-1 are blocked from code.google.com, and AMS-3 are blocked from both storage.googleapis.com and code.google.com (403, ACCESS DENIED: “We’re sorry, but this service is not available in your country”).

It’s not possible to download packages from code.google.com (the install fails on downloading websockets package in the revel install), and downloading the latest version of golang is also not possible (on AMS-3 at least).

I have tested new droplets on AMS-1 and AMS-2, and they seem to work fine.

In other words, you will not be able to set up go and revel on AMS-3 and UK-1 droplets.

It would be nice if the article could be updated with info about this until the issues are resolved (by google), so you don’t waste hours trying to figure out why it’s not working.

the command

wget http://go.googlecode.com/files/go1.1.1.linux-amd64.tar.gz

does not work for me. I constantly get ERROR 403: Forbidden. Anyone else having this issue?

The new path as of the end of Feb 2014, is;


I followed these instructions to the letter and with the exception of one issue it all worked great, so thank you!

The only issue I has was the Revel command line tool was missing. It seems step 4 should include one extra step for the command line tool. As per the Revel site’s instruction you need to do the flowing:

Get the Revel Framework: go get github.com/robfig/revel Build the Revel command line tool: go get github.com/robfig/revel/revel

@ladislav @me: Both should work just fine.

The link in sted 4 must be:

go get github.com/robfig/revel/revel

I. e. “revel” is twice there!

The link is broken, should be go get github.com/robfig/revel/, not go get github.com/robfig/revel/revel

Instead of using git directly to pull the latest changes and rebuild, wouldn’t “go get -u github.com/robfig/revel/revel” do the same thing?
