Ubuntu: setting up redis-server (reloaded)

Monday, November 28. 2011
Comments

I blogged about setting up redis before, here's a small update to the situation:

If you're running Ubuntu 9.10 or 10.04.x, the most recent release available through aptitude is 1.x. Version 1.x doesn't include many things (pubsub, etc.) which are available in 2.x. So this leaves you with two options!

Compile!

Compiling redis-server is simple (aka, make && sudo make install), a few things were missing (last time I checked):

Using a PPA!

The PPA (Personal Package Archive) concept is great. In a nutshell, it allows anyone to publish packages for various (Ubuntu) distributions. You upload a definition (sort of) and leverage Canonical's build farm, etc.. There are a few downsides to Launchpad: it's confusing, your PPA only holds the latest version of your build and overall publishing packages could be a lot easier. Which is why I'm so thankful for everyone who takes the time to publish.

Chris Lea seems to build most of the software I need. And he put all packages online in various Launchpad PPAs! Kudos to him!

Here's how you get setup!

Discover the Launchpad PPA:

server# sudo add-apt-repository ppa:chris-lea/redis-server
...

Update sources and install redis!

server# sudo apt-get update
...
server# sudo apt-get install redis-server
...

Done! ;-) All things (start script, configs) included!

In case that's too much type or you're looking for some automation, I also have a chef-recipe to get this done!

Looking for Two PHP Developers in NYC

Hey everyone,

it's my sincere pleasure to announce that we're looking to fill two positions for PHP developers (entry/junior) in NYC.

Expectations

This is what we look for from candidates:

  • A strong and firm knowledge of PHP5
  • First hand experience with the Zend Framework
  • You've heard of PHPUnit and TDD
  • An idea of what a HTTP request is and the different applications that take part in one
  • You heard of CouchDB, MongoDB or Redis (generally "NoSQL") before

Last but absolutely not least:

We very, very, very much prefer people who contribute(d) to Open Source.

Playground

  • A web start-up.
  • The not-so-standard LAMP stack with: Linux, Nginx, PHP and mostly CouchDB.
  • A lot time to play with Amazon Web Services.
  • Size matters to you? Databases and indices in the 100 millions.
  • Maybe Solr!
  • Definitely Redis!

... generally, we always try to use the right tool for the job.

If you're interested, please email me your resume:

till+nyphp@imagineeasy.com

If you know someone else and we happen to hire this person my special referral bonus is a couple beers next time we meet. ;-) [Disclaimer: If you're 1821, or older.]

Redis on Ubuntu (9.04)

A small howto to get the latest redis-server and a webinterface on Ubuntu.

Installation

$ wget http://ftp.de.debian.org/debian/pool/main/r/redis/redis-server_1.2.5-1_amd64.deb
...
$ sudo dpkg -i redis-server_1.2.5-1_amd64.deb
...
$ /etc/init.d/redis-server start

... redis should listen on localhost:6379.

You may need to get i386 instead of amd64 if you run 32bit.

Tweaks

You may need to add the following to /etc/sysctl.conf:

vm.overcommit_memory = 1

... that is, especially if you run in a VE (e.g. inside xen).

All other configs are in /etc/redis/redis.conf.

Web

Because web interfaces are so simple, I decided to get redweb.

Dependencies

wget http://ftp.us.debian.org/debian/pool/main/p/python-support/python-support_1.0.7_all.deb
dpkg -i python-support_1.0.7_all.deb
wget http://ftp.us.debian.org/debian/pool/main/p/python-redis/python-redis_1.34.1-1_all.deb
dpkg -i python-redis_1.34.1-1_all.deb

So, on Ubuntu, python-support is at 0.8.4 currently, but we'll need something equal or greater than 0.9.0. This is why I update python-support from Debian.

Installation

git clone http://github.com/tnm/redweb ./redweb-git

Patch redweb-git/redweb/redweb.py with:

index e79a062..e278fca 100644
--- a/redweb/redweb.py
+++ b/redweb/redweb.py
@@ -15,6 +15,8 @@ __author__ = 'Ted Nyman'
__version__ = '0.2.2'
__license__ = 'MIT'

+import sys
+sys.path.append('/path/to/redweb-git/')

from bottle import route, request, response, view, send_file, run
import redis

Run!

cd redweb-git/redweb/
python redweb.py

... this is a bit annoying. If you do python redweb/redweb.py, it'll complain about missing files.

Then browse to http://127.0.0.1:8080.

Fin

So this is my redis-server howto — nice and simple.

And once you have Redis up and running, feel free to browse over to Rediska and use their session handling for Zend Framework. Setup is pretty simple and it works like a charm. :-) I'd suggest you use their trunk code, which is hosted on Github as it will contain a few improvements and a small bugfix which I did.

For more on Rediska, watch this space. ;-)
