Memcached windows 下安裝與測試

   Memcached 是一個高效能的分布式記憶體對象緩衝系統，用於動態Web應用以減輕資料庫負載。它通過在記憶體中快取資料和對象來減少讀取資料庫的次數，從而提供動態、資料庫驅動網站的速度。Memcached基於一個儲存鍵/值對的hashmap。其守護進程（daemon ）是用C寫的，但是用戶端可以用任何語言來編寫，並通過memcached協議與守護進程通訊。但是它並不提供冗餘（例如，複製其hashmap條目）；當某個伺服器S停止運行或崩潰了，所有存放在S上的鍵/值對都將丟失。

下載Windows的Server端

下載地址：http://code.jellycan.com/memcached/

安裝Memcache Server(也可以不安裝直接啟動)

1. 下載memcached的windows穩定版，解壓放某個盤下面，比如在c:\memcached
2. 在CMD下輸入 "c:\memcached\memcached.exe -d install" 安裝.
3. 再輸入："c:\memcached\memcached.exe -d start" 啟動。NOTE: 以後memcached將作為windows的一個服務每次開機時自動啟動。這樣伺服器端已經安裝完畢了。

如果下載的是二進位的版本，直接運行就可以了，可以加上參數來加以設定。

常用設定：
-p <num>          監聽的連接埠
-l <ip_addr>      串連的IP地址, 預設是本機
-d start          啟動memcached服務
-d restart        重起memcached服務
-d stop|shutdown  關閉正在啟動並執行memcached服務
-d install        安裝memcached服務
-d uninstall      卸載memcached服務
-u <username>     以<username>的身份運行 (僅在以root啟動並執行時候有效)
-m <num>          最大記憶體使用量，單位MB。預設64MB
-M                記憶體耗盡時返回錯誤，而不是刪除項
-c <num>          最大同時串連數，預設是1024
-f <factor>       塊大小增長因子，預設是1.25
-n <bytes>        最小分配空間，key+value+flags預設是48
-h                顯示協助

然後就可以用.net 的memcached用戶端來試一下了。
