Organic groups, Panels and Views in Drupal 7

Submitted by steev on

I've done three Organic group sites this year already, with at least 2 more on the horizon so best get this documented. It all pretty much works as expected but for one small change to where you get the argument from in the views pane - but i've decided to document the whole process.

Enable these core modules:

  • Blog
  • Forum
  • Poll
  • Statistics
  • Tracker

Install and enable at least:

How to install Drupal 7 on Apache 2.2 on Fedora Core 16 with SELinux enabled

Submitted by steev on

For production we ordinarily use Nginx and PHP-fpm, but for developer machines, perhaps the apache environment with its wealth of documentation and large userbase would enable the developer to be a bit more autonomous.

The process for configuring apache hasn’t really changed for a long time, build vhosts in /etc/httpd/conf/httpd.conf or an included file in /etc/httpd/conf.d/ - a well known process documented many places.

An known good example Vhosts for Drupal 6 and 7 is below:

How to verify SSH key signatures for Github hack

Submitted by steev on

Github today anounced that elements of their service (and your code!) may have been compromised. The full PR statement is here https://github.com/blog/1068-public-key-security-vulnerability-and-mitig....

So essentially someone may have been able to add ssh keys to your account to push/pull/clone etc. So you need to verify the fingerprint of each key.

How to compile IDJC with mp3 support on 64bit Fedora Core 15

Submitted by steev on

IDJC (Internet Disc Jockey Console) is the app you want to use if you need to run a traditional DJing setup with multiple mics for the DJ plus guests (skype is supported amongst others) and have two decks with which to crossfade and pitch correct mp3s into the mix. In addition it all integrates with jackd so you can output whatever you need to wherever you need it. It's been rock solid for me so far and i can't reccomend it enough. You can read about it here http://idjc.sourceforge.net/

Configure postfix for Drupal development

Submitted by steev on

Drupal sends a lot of email given half a chance. Especially with modules like messaging and notifications its possible to send email when new content is generated, when taxonomy terms are updated etc. It is generally considered 'poor practice' to send your user base test emails from your dev machine 'Testing from dev machine' sent to 50 000 users, wins you no friends and may lose you clients!

How to Nginx 0.8.54, php-fpm 5.2.17, mariadb and drupal 6.19

Submitted by steev on

The cloud has led to many improvements in LAMP architecture. No client wants to throw tin at performance problems anymore. seems there is always a way to work smarter. So my acronyms may be screwed (who want's to install a LNMPC?) - but if Carlsberg made software stacks for CMS, they'd probably use this...

Ushahidi for Ubuntu 10.4 php5.2 and Mcrypt

Submitted by steev on

For a few days in my offtime i've been meaning to play with Ushahidi and the Ushahidi platform. All was going swimmingly until the installer complained about a missing php5 mcrypt module. There are a host of issues regarding php 5.3 and luckily i had already downgraded to php 5.2 on a test server, but strangely i was still getting this error.


$ sudo apt-get install php5-mcrypt
