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 ~]# yum remove php  php-bcmath php-cli php-common  php-devel php-fpm    php-gd php-imap  php-ldap php-mbstring php-mcrypt php-mysql   php-odbc   php-pdo   php-pear  php-pecl-igbinary  php-xml php-xmlrpc

[root@iZ28vpjayxiZ ~]# rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm

[root@iZ28vpjayxiZ ~]# yum install php55w  php55w-bcmath php55w-cli php55w-common  php55w-devel php55w-fpm    php55w-gd php55w-imap  php55w-ldap php55w-mbstring php55w-mcrypt php55w-mysql   php55w-odbc   php55w-pdo   php55w-pear  php55w-pecl-igbinary  php55w-xml php55w-xmlrpc php55w-opcache php55w-intl php55w-pecl-memcache

[root@iZ28vpjayxiZ ~]# service httpd restart

[root@iZ28vpjayxiZ ~]# wget https://launchpad.net/libmemcached/1.0/1.0.16/+download/libmemcached-1.0.16.tar.gz

[root@iZ28vpjayxiZ ~]# tar zxvf libmemcached-1.0.16.tar.gz

[root@iZ28vpjayxiZ ~]# cd libmemcached-1.0.16

[root@iZ28vpjayxiZ libmemcached-1.0.16]# ./configure --prefix=/usr/local/libmemcached --enable-sasl

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

[root@iZ28vpjayxiZ ~]# yum install zlib-devel

[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
