[PHP] Detailed explanation of Alibaba Cloud upgrading PHP to 5.5

Purpose

Use the new version of PHP to improve code execution efficiency

Difference from the offline environment

The database uses RDS service, there is no need to install MYSQL locally

To use the cache service, you need to install the official memcached extension

Required to install Extensions

memcached,yar,memcached,apc,mycrypt

Install

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

[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

   * VCS checkout:              no

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

[root@iZ28vpjayxiZ libmemcached-1.0.16]# cd ../
[root@iZ28vpjayxiZ ~]# yum install zlib-devel
Loaded plugins: security
Setting up Install Process
Package zlib-devel-1.2.3-29.el6.x86_64 already installed and latest version
Nothing to do

[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
