    # OSX: Run two instances of Redis

    ## Copy and update redis.conf
    The redis configuration file is likely located at /usr/local/etc/redis.conf

    cp /usr/local/etc/redis.conf /usr/local/etc/redis2.conf

    Change the port number from 6379 to something else. I used 6380

    # Accept connections on the specified port, default is 6379.
    # If port 0 is specified Redis will not listen on a TCP socket.
    port 6380

    ## Create a Launch Agent
    The LaunchAgent makes it easy to start the second redis instance

    cp ~/Library/LaunchAgents/homebrew.mxcl.redis.plist ~/Library/LaunchAgents/homebrew.mxcl.redis2.plist

    Edit the LaunchAgent and change the following:

    From: <string>homebrew.mxcl.redis</string>
    To: <string>homebrew.mxcl.redis2</string>

    From: <string>/usr/local/etc/redis.conf</string>
    To: <string>/usr/local/etc/redis2.conf</string>

    From: <string>/usr/local/var/log/redis.log</string>
    To: <string>/usr/local/var/log/redis2.log</string>

    From: <string>/usr/local/var/log/redis.log</string>
    To: <string>/usr/local/var/log/redis2.log</string>

    ## Load the service

    launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.redis2.plist

    ## Start the service

    launchctl start -w ~/Library/LaunchAgents/homebrew.mxcl.redis2.plist

    ## Verify
    Verify that the service is running (Note the port number)

    ## Helpful Hints

    1. redis-cli will default to port 6379. Add the port parameter to use redis-cli with the new database `redis-cli -p 6380`
