打开终端

brew install redis

如下

~ w$ brew install redis
==> Downloading https://homebrew.bintray.com/bottles/redis-3.0.0.yosemite.bottle

==> Pouring redis-3.0.0.yosemite.bottle.tar.gz
==> Caveats
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
==> Summary
🍺  /usr/local/Cellar/redis/3.0.0: 9 files, 892K

安装成功，启动redis
