Installing Cassandra on Mac OS X
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)"
Mac OS X has a copy of Python preinstalled, but this makes sure you get the newest version.
brew install python
To use cqlsh, the Cassandra query language shell, you need to install cql:
pip install cql pip install cassandra-driver
This installs Apache Cassandra:
brew install cassandra
At the end of the install, brew will tell you about two ways to launch Cassandra. The first will launch it when the computer restarts, but this isn't recommended because you may not want to always run Cassandra. Instead use this command:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.cassandra.plist
Or even easier:
launchctl start homebrew.mxcl.cassandra
and to stop:
launchctl stop homebrew.mxcl.cassandra
On Mavericks, Homebrew failed to move the plist file into LaunchAgents. Which gives this error message:
launchctl: Couldn't stat("/Users/MNCH/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/2.1.2/homebrew.mxcl.cassandra.plist ~/Library/LaunchAgents/
Cassandra file locations
Finally cqlsh should connect to cassandra:
$> cqlsh Connected to Test Cluster at 127.0.0.1:9042. [cqlsh 5.0.1 | Cassandra 2.1.2 | CQL spec 3.2.0 | Native protocol v3] Use HELP for help. cqlsh> cqlsh>
Have fun with Cassandra!
