After many unsuccessful attempts to install MySQL using MacPorts, I gave up and tried something much simpler. Go to the MySQL downloads page (http://dev.mysql.com/downloads/mysql/) and download the latest DMG (http://dev.mysql.com/downloads/mirror.php?id=408354). The DMG will come with two packages, the application and a package to make MySQL run on startup. Also install MySQL.prefPane to have a nice interface to stop/start mysql daemon. To start, just go to your system preferences and click the MySQL icon to start. And that's it, go to command line and type:

/usr/local/mysql/bin/mysql

I have recently been using Amazon Web Services to setup an array of different servers for use with gearmand, memcached, etc. There are some dependencies but yum makes it easy to grab these and get them installed. The gearmand version below maybe out of date, so please check launchpad.net for the latest version.

Out of the box the Node Import module doesn't play nice with the Organic Groups module. When trying to configure nodes to be posted into a group after the content import, two Drupal database tables are important: og_access_post and og_ancestry. The og_access_post table has two columns, nid and og_public. The og_public field should either 0 or 1 depending on whether you want the post to be public or not. The og_ancestry table also has two columns, nid and group_nid. After importing content, it is import to update these two tables with the appropriate data.

.code {
background: #ffffd0; margin: 12px 12px 12px 12px; padding: 3px 3px 3px 3px;
}

//$form['#field_info'] contains information about cck fields
function _cck_form_array($type) {
module_load_include('inc', 'node', 'node.pages');
global $user;
$form_state = array();
$node = array('type' => $type, 'uid' => $user->uid, 'name' => $user->name);
$form = drupal_retrieve_form($type.'_node_form',$form_state,$node);
drupal_prepare_form($type.'_node_form', $form, $form_state);
return $form;
}

I was unable to import node reference fields that were autocomplete fields. To make this work, I had to change the node reference field to a select field. Then in the csv, use the Title of the node to import that reference. Also, when trying to import a field that is a single on/off checkbox, I wasn't able to import the on value. I kept receiving an invalid value error. To fix this I had to change the single on/off value to a regular select field.

When trying to install Drupal and entering database credentials, the page just reloads with no error messages displayed. The problem is because the default.settings.php file was renamed instead of copied. You must copy this file and rename the copy.
