1.获取编译工具下面要用来编译源代码，如果已经安装可跳过这步

  [bash] sudo apt-get install build-essential [/bash]

 2.安装PEAR and memcached

  [bash] sudo apt-get install php-pear memcached [/bash]

 3.编译libmemcached

  到 https://launchpad.net/libmemcached/+download 下载最新的libmemcached源代码，解压编译安装步骤如下：

  Extract the files with your preferred method, or type:

  [bash] tar -xzf libmemcached-0.37.tar.gz [/bash]

  Move into the extracted directory:

  [bash] cd libmemcached-0.37/ [/bash]

  Configure the package.

  [bash] ./configure –with-memcached [/bash]

  Make.

  [bash] make [/bash]

  Make install. Note this probably will require sudo rights.

  [bash] sudo make install [/bash]

 4.PECL

  [bash] sudo pecl install memcached [/bash]

  When this process completed, you should see something like this:

  [bash]

  Build process completed successfully

  Installing ‘/usr/lib/php5/20060613+lfs/memcached.so’

  install ok: channel://pecl.php.net/memcached-1.0.0

  Extension memcached enabled in php.ini

  [/bash]

 5.修改PHP.INI添加扩展

  [bash] sudo vi /etc/php5/fpm/php.ini [/bash] 

  在php.ini 中添加“extension = memcached.so”

  重启PHP-FPM服务

  [bash] sudo service php5-fpm restart [/bash]
