After some research I found that there is a Win32 binary version of memcached available here.

So go there and download win32 binary version to your computer. When downloaded, extract the file to folder memcahced on your C partition.

You should get only one file named memcached.exe. Now we need to install this as a service, as memCached is daemon and should be run only as service.

To install Memcached as a service, follow these steps (please change all forward slashes to backslashes):

1. If you’re running Vista, you should set memcached.exe to Run as administrator
2. Install the service using the command:

   1	c:/memcached/memcached.exe  -d install

   from the command prompt

3. Start the server from the Services or by running one of the following commands:

   1	c:/memcached/memcached.exe -d  start

   or

   1	net start "memcached Server"

That is it, now your memcached server is installed and is listening to port 11211. There is one more thing left to do. By default, server is set to 64Mb memory limit, which is too small. To correct, go to Registry Editor and find key

1	HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/memcached  Server .

Change the ImagePath entry to:

1	“C:/memcached/memcached.exe” -d runservice -m 512

This way you will use 512 Mb memory limit for your server.

If you are using WAMP, then just turn on php_memcache extension in it. Now we are ready to go testing.

The simplest test is to write something to memcache that will expire in 30 seconds, and then try to retrieve the value from cache.

So write this into your test file:

01

<?php

02	$memcache = new Memcache; // instantiating memcache extension class

03	$memcache->connect("localhost",11211); // try 127.0.0.1 instead of localhost

04	// if it is not working

05

06	echo "Server's version: " . $memcache->getVersion() . "<br />\n";

07

08	// we will create an array which will be stored in cache serialized

09	$testArray = array('horse', 'cow', 'pig');

10	$tmp       = serialize($testArray);

11

12	$memcache->add("key", $tmp, 30);

13

14	echo "Data from the cache:<br />\n";

15	print_r(unserialize($memcache->get("key")));

16

?>

If everything went ok, you should see your array written out of memcache. Now you can use this powerful caching mechanism to develop really fast PHP applications. If you need to know more, go to PHP manual Memcached page

Memcached的基本設置

-p 監聽的端口
-l 連接的IP地址, 默認是本機
-d start 啓動memcached服務
-d restart 重起memcached服務
-d stop|shutdown 關閉正在運行的memcached服務
-d install 安裝memcached服務
-d uninstall 卸載memcached服務
-u 以的身份運行 (僅在以root運行的時候有效)
-m 最大內存使用，單位MB。默認64MB
-M 內存耗盡時返回錯誤，而不是刪除項
-c 最大同時連接數，默認是1024
-f 塊大小增長因子，默認是1.25
-n 最小分配空間，key+value+flags默認是48
-h 顯示幫助
