1.分別把memcached和libevent下載回來，放到自己下載的目錄下：

# wget http://www.danga.com/memcached/dist/memcached-1.2.5.tar.gz
# wget http://www.monkey.org/~provos/libevent-1.2.tar.gz

# tar zxvf libevent-1.2.tar.gz
# cd libevent-1.2
# ./configure -prefix=/usr      #這是安裝到的目錄
# make
# make install

# ls -al /usr/lib | grep libevent
 

# tar zxvf memcached-1.2.0.tar.gz
# cd memcached-1.2.0
# ./configure -with-libevent=/usr     #這是安裝到的目錄
# make
# make install

5.測試是否成功安裝memcached：

ls -al /usr/local/bin/memcached

2.下載到指定的目錄並進行解壓然後進入解壓後的目錄

3.用phpize生成configure配置檔案

/phpstudy/server/php/bin/phpize

./configure -enable-memcache --with-php-config=/phpstudy/server/php/bin/php-config --with-zlib-dir
make     編譯
make install   安裝

/phpstudy/server/php/lib/php/extensions/no-debug-non-zts-20121212/
 

extension_dir = “/phpstudy/server/php/lib/php/extensions/no-debug-non-zts-20121212/”

extension=memcache.so
