Installing redis using homebrew on Mac

redis_homebrew_installaion

$ brew install redis

To have launchd start redis at login:
$ ln -sfv /usr/local/opt/redis/*.plist ~/Library/LaunchAgents

Then to load redis now:
$ launchctl load ~/Library/LaunchAgents/homebrew.mxcl.redis.plist

Or, if you don't want/need launchctl, you can just run:
$ redis-server /usr/local/etc/redis.conf
