Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.

Elasticsearch: updating the mappings and settings of an existing index

Note: This was written using elasticsearch 0.9.

Elasticsearch will automatically create an index (with basic settings and mappings) for you if you post a first document:

$ curl -X POST 'http://localhost:9200/thegame/weapons/1' -d \

After upgrading to OSX Lion, I discovered that both PEAR and PECL had gone missing. It turns out that you have to re-install them, but luckily it's quite simple. I found this quick guide from Ruggero De Pellegrini on Google+, and thought I would share the info to save you the confusion:

1. Download the installer curl http://pear.php.net/go-pear.phar > go-pear.php
2. Start the installation procedure with sudo sudo php -q go-pear.php
3. Select a new installation base ($prefix) e.g. /usr/local
4. Proceed with the install.
5. If there is no /etc/php.ini file yet, copy the default sudo cp /etc/php.ini.default /etc/php.ini
6. Edit /etc/php.ini and change the line ;include_path = ".:/php/includes" to include_path = ".:/usr/local/share/pear"
7. Add /usr/local/bin/ to your path if you haven't already, e.g. in .profile
