Different MongoDB Version with homebrew

descrizione.markdown

Homebrew non supporta l'installazione scegliendo la versione da installare.

Il mio caso è stato : Ho installato mongodb2.0 ma ho bisogno di mongodb1.8

brew create http://fastdl.mongodb.org/osx/mongodb-osx-x86_64-1.8.4.tgz

Questo crea un file ruby: /user/local/Library/Formula/mongodb-osx-x86_64.rb

Per aprire questo file (homebrew chiama formula) :

brew edit mongodb-osx-x86_64

(allegato sotto)

per capire che comandi bisgona fare all'interno ho controllato con il mongodb2.0 già installato :

brew edit mongodb

(allegato sotto)

infine

brew install mongodb-osx-x86_64-1.8.4

ed ho due versioni di mongo installate con homebrew..

Utile questa guida di homebrew https://github.com/mxcl/homebrew/wiki/Formula-Cookbook
