一、memcached 的編譯安裝
準備:
Memcached下載地址：http://www.danga.com/memcached/
libevent下載地址: http://monkey.org/~provos/libevent/

1.分別把memcached和libevent下載回來，放到 /tmp 目錄下：
# cd /tmp
# wget http://www.danga.com/memcached/dist/memcached-1.2.0.tar.gz
# wget http://www.monkey.org/~provos/libevent-1.2.tar.gz

2.先安裝libevent：
# tar zxvf libevent-1.2.tar.gz
# cd libevent-1.2
# ./configure –prefix=/usr
# make
# make install

3.測試libevent是否安裝成功：
# ls -al /usr/lib | grep libevent
lrwxrwxrwx 1 root root 21 11?? 12 17:38 libevent-1.2.so.1 -> libevent-1.2.so.1.0.3
-rwxr-xr-x 1 root root 263546 11?? 12 17:38 libevent-1.2.so.1.0.3
-rw-r–r– 1 root root 454156 11?? 12 17:38 libevent.a
-rwxr-xr-x 1 root root 811 11?? 12 17:38 libevent.la
lrwxrwxrwx 1 root root 21 11?? 12 17:38 libevent.so -> libevent-1.2.so.1.0.3
還不錯，都安裝上了。

4.安裝memcached，同時需要安裝中指定libevent的安裝位置：
# cd /tmp
# tar zxvf memcached-1.2.0.tar.gz
# cd memcached-1.2.0
# ./configure –with-libevent=/usr
# make
# make install
如果中間出現報錯，請仔細檢查錯誤信息，按照錯誤信息來配置或者增加相應的庫或者路徑。
安裝完成后會把memcached放到 /usr/local/bin/memcached ，

5.測試是否成功安裝memcached：
# ls -al /usr/local/bin/mem*
-rwxr-xr-x 1 root root 137986 11?? 12 17:39 /usr/local/bin/memcached
-rwxr-xr-x 1 root root 140179 11?? 12 17:39 /usr/local/bin/memcached-debug

?

安裝步驟:
1. 下載libevent & memcached 源碼包

???? libevent-1.3.tar.gz
???? memcached-1.2.2.tar.gz

2. 解壓縮 libevent-1.3.tar.gz ，編譯安裝

???? # tar zxvf?? libevent-1.3.tar.gz
???? # cd libevent-1.3?
???? # ./configure --prefix=/usr/local/libevent
???? # make ; make install

3. 解壓縮 memcached-1.2.2.tar.gz, 編譯安裝

???? # tar zxvf memcached-1.2.2.tar.gz?
???? # cd memcached-1.2.2?
???? # ./configure --prefix=/usr/local/memchached --with-libevent=/usr/local/libevent?
???? # make;make install

4. 作軟連接，否則運行memcached的時候將找不到libevent模塊

???? # ln -s /usr/local/libevent/lib/libevent-1.3.so.1 /usr/lib

5.啟動memcached

???? # /usr/local/memcached/bin/memcached -d -m 256 -p 11211 -u root

OK ！！！ 搞定！ ^^

二、php的memcached模塊

# tar vxzf memcache-1.5.tgz
# cd memcache-1.5
# /usr/local/php/bin/phpize
# ./configure --enable-memcache --with-php-config=/usr/local/php/bin/php-config --with-zlib-dir
# make
# make install

安裝完后會有類似這樣的提示：

Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20050922/

把這個記住，然后修改php.ini，把

extension_dir = "./"

修改為

extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20050922/"

并添加一行

extension=memcache.so

3、測試腳本

自己寫一個PHP程序測試一下吧

<?php
???? $memcache = new Memcache; //創建一個memcache對象
???? $memcache->connect('localhost', 11211) or die ("Could not connect"); //連接Memcached服務器
???? $memcache->set('key', 'test'); //設置一個變量到內存中，名稱是key 值是test
???? $get_value = $memcache->get('key'); //從內存中取出key的值
???? echo $get_value;
?>
