    Installing memcached on Mac with Homebrew and Lunchy

This is a quick guide for installing memcached on a Mac with Homebrew, and starting and stopping it with Lunchy. I hope this tutorial will get your memcached up and running in no time.
Step 1 — Install Homebrew

Installing Homebrew is super easy. Just paste this in your terminal —
$ ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
You should also make sure your Homebrew is up-to-date. Use update and doctor commands to update and fix any issues it may have.
$ brew update
$ brew doctor
Step 2 — Install memcached

Installing anything with Homebrew is a breeze. All you need is
$ brew install memcached
When you installed memcached, it put a file named homebrew.mxcl.memcached.plist in /usr/local/Cellar/memcached/$version/; you copy that file into ~/Library/LaunchAgents and then tell launchd to start it with launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.memcached.plist.
If you were watching the console carefully during the brew install command, it should have said something about doing these exact steps. If you run brew info it’ll re-print this information, e.g. brew info memcached.
Step 3 — Install Lunchy

But why remember this long location to start memcached every time? Lunchy is a gem that simplifies the command line interface to launchctl. To install Lunchy, do
$ gem install lunchy
Step 4 — Start/Stop memcached

Now we configure lunchy to start/stop memcached using simple lunchy commands.
$ mkdir ~/Library/LaunchAgents
$ cp /usr/local/Cellar/memcached/$version/homebrew.mxcl.memcached.plist ~/Library/LaunchAgents/
$ lunchy start memcached
$ lunchy stop memcached
Lines 1 and 2 copy the plist file to LaunchAgents. The lines 3 and 4 start and stop memcached. Since lunchy takes care of the long commands we talked about in Step 2, we don’t have to use the launchctl command to launch anymore.
Verify the Installation

Verify that you have successfully installed Memcached.
$ memcached -V
Using the Memcached Telnet Interface
You can connect to the Memcached server with Telnet.
telnet localhost 11211
To test if everything is working correctly, set a cache item.
set foo 0 900 5
hello
To retrieve the cache item.
get foo
To exit the Telnet session.
quit
For more information on using Memcached Telnet commands.
Invalidate All Cache Items

To flush the contents of your Memcached server. Useful in a development environment.
echo 'flush_all' | nc localhost 11211
That's it.
