Installing Cassandra on Mac OS X
Install Homebrew
Homebrew is a great little package manager for OS X. If you haven't already, installing it is pretty easy:
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
Install Python
Mac OS X has a copy of Python preinstalled, but this makes sure you get the newest version.
brew install python
Install cql
To use cqlsh, the Cassandra query language shell, you need to install cql:
pip install cql
Install Cassandra
This installs Apache Cassandra:
brew install cassandra
Starting/Stopping Cassandra
Use this command to start Cassandra:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.cassandra.plist
Use this command to stop Cassandra:
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.cassandra.plist
On Mavericks, Homebrew failed to move the plist file into LaunchAgents, which gives this error message:
launchctl: Couldn't stat("/Users/<user>/Library/LaunchAgents/homebrew.mxcl.cassandra.plist"): No such file or directory
To fix this just issue the following command. Then, try using the launchctl load
command again:
cp /usr/local/Cellar/cassandra/<version number>/homebrew.mxcl.cassandra.plist ~/Library/LaunchAgents/
