Thinking about ways to improve the performance of some of my web servers
I\'ve begun to toy with Memcached. These notes are to remind me how to
set it up (I\'m using Mac OS X 10.5, Apache 2 and PHP 5.2.10, as
provided by Apple). Erik\'s blog post [Memcached with PHP on Mac OS
X](http://af-design.com/blog/2008/10/18/memcached-with-php-on-mac-os-x/)
has a step-by-step guide, based on the post [Setup a Memcached-Enabled
MAMP Sandbox
Environment](http://www.lullabot.com/articles/setup-memcached-mamp-sandbox-environment)
by Nate Haug, and I\'ve basically followed the steps they outline.  

1.  **Install the Memcached service on Mac OS X:** Follow the
    instructions in Nate Haug\'s
    [post](http://www.lullabot.com/articles/setup-memcached-mamp-sandbox-environment).

2.  **Install Memcache PHP Extension:** Apple\'s PHP doesn\'t come with
    the PECL package for memcache so [download
    it](http://pecl.php.net/package/memcache). To compile it go:  

        phpize
        ./configure
        make
        sudo make install

      
    One important point. If you are running 64-bit Mac OS X (as I am),
    ./configure by itself won\'t build a usable extension. However, [a
    comment by
    Matt](http://af-design.com/blog/2008/10/18/memcached-with-php-on-mac-os-x/#comment-719)
    on Erik\'s original post provides the solution. Instead of just
    ./configure, type this at the command prompt:  

    ::: {style="font-family:Courier;font-size:12px;"}
      
    MACOSX_DEPLOYMENT_TARGET=10.5 CFLAGS=\"-arch ppc -arch ppc64 -arch
    i386 -arch x86_64 -g -Os -pipe -no-cpp-precomp\" CCFLAGS=\"-arch ppc
    -arch ppc64 -arch i386 -arch x86_64 -g -Os -pipe\" CXXFLAGS=\"-arch
    ppc -arch ppc64 -arch i386 -arch x86_64 -g -Os -pipe\"
    LDFLAGS=\"-arch ppc -arch ppc64 -arch i386 -arch x86_64
    -bind_at_load\" ./configure
    :::

      
      
    Then follow the rest of Erik\'s instructions for adding the
    extension to your copy of PHP.

3.  **Restart Apache:** You can do this by restarting Web sharing in
    System preferences. Use the
    [phpinfo();]{style="font-family:Courier;"} command to check that the
    extension is working. You should see something like this:  

    ::: {style="text-align:center;"}
    ![memcache.png](http://lh3.ggpht.com/_Gct8lVAxKqQ/Stm5R4EuiFI/AAAAAAAAAkc/jlbYMibXRYQ/memcache.png?imgmax=800){border="0"
    width="380"}
    :::

      
    If you don\'t see this, something\'s gone wrong. The Apache web log
    may help (for example, that\'s where I discovered that I had the
    problem reported by several people who commented on [Erik\'s
    post](http://af-design.com/blog/2008/10/18/memcached-with-php-on-mac-os-x/).

4.  You can start the memcached daemon like this:  

        # /bin/sh
        memcached -m 1 -l 127.0.0.1 -p 11211 -d

  
Now, I just need to explore how to actually use this\...
