### 目的
使用新版本PHP，提高代码执行效率
### 和线下环境的不同
数据库采用RDS服务，本地不需要安装MYSQL
使用缓存服务，需要安装官方的memcached扩展
### 需要安装的扩展
memcached,yar,memcached,apc,mycrypt
### 安装
### 升级php

[root@iZ28vpjayxiZ html]# yum install cyrus-sasl-plain cyrus-sasl cyrus-sasl-devel cyrus-sasl-lib

[root@iZ28vpjayxiZ ~]# cd libmemcached-1.0.16

[root@iZ28vpjayxiZ libmemcached-1.0.16]# make && make install

[root@iZ28vpjayxiZ ~]# wget http://pecl.php.net/get/memcached-2.1.0.tgz
[root@iZ28vpjayxiZ ~]# tar zxvf memcached-2.1.0.tgz
[root@iZ28vpjayxiZ ~]# cd memcached-2.1.0
[root@iZ28vpjayxiZ memcached-2.1.0]# phpize
[root@iZ28vpjayxiZ memcached-2.1.0]# ./configure --with-libmemcached-dir=/usr/local/libmemcached --enable-memcached-sasl
[root@iZ28vpjayxiZ memcached-2.1.0]# make && make install
最后修改php.ini文件（locate找该文件，yum安装的一般在/etc/php.ini 如果系统中有两套PHP环境，需找到使用OCS的PHP环境路径，对应修改之），增加extension=memcached.so
memcached.use_sasl = 1
执行php –m |grep memcached 如显结果有 memcache 表示环境已支持memcache

### yar
~~~
[root@iZ28vpjayxiZ ~]# pecl install channel://pecl.php.net/msgpack-0.5.5
#修改php.ini 增加 extension=msgpack.so
[root@iZ28vpjayxiZ ~]# pecl install yar
yes
#修改php.ini 增加 extension=yar.so
#由于yar需要json支持，所以需要先加载json.so
