PHP7和HHVM比較
PHP7的在真实场景的性能确实已经和HHVM相当, 在一些场景甚至超过了HHVM。

HHVM的运维复杂, 是多线程模型, 这就代表着假设一个线程导致crash了, 那么整个服务就挂了, 而且它不会自己主动重新启动。

另外它採用JIT, 那么意味着, 重新启动以后要预热, 没有预热的情况下, 性能较为糟糕。而且多线程模型调试困难, 这对于追求稳定来说的Web服务来说, 是非常不适合的。


Nginx以及PHP7.0之前的版本号能够參考此文:Linux环境Nginx安装与调试以及PHP安装


PHP7.0正式版已经在2015年11月份左右公布。眼下是PHP7.0.2版本号,本人最早是从2015年8月php7的第一个測试版跟起,如今正式版公布。

linux版本号:64位CentOS 6.6

Nginx版本号:nginx1.8.0

php版本号:php-7.0.2


下载

# wget  http://php.net/get/php-7.0.2.tar.gz/from/a/mirror


建议安装之前先看看安装帮助文件INSTALL

解压安装
# tar zxvf php-7.0.2.tar.gz
# cd php-7.0.2
首先查看安装帮助
# ./configure   --help
# ./configure --prefix=/usr/local/php \

 --with-freetype-dir \
 --with-gd \

 --with-libxml-dir \

假设配置错误,须要安装须要的模块,直接yum一并安装依赖库

# yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel mysql pcre-devel


注意:安装php7beta3的时候有几处配置只是去,须要yum一下。如今php-7.0.2已经不用这样了。

# yum -y install curl-devel
# yum -y install libxslt-devel

编译安装
# make &&  make install

配置文件
cp php.ini-development /usr/local/php/lib/php.ini
# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
# cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
# cp -R ./sapi/fpm/php-fpm /etc/init.d/php-fpm

须要注意的是php7中www.conf这个配置文件配置phpfpm的端口号等信息,假设你改动默认的9000端口号需在这里改,再改nginx的配置
启动
#  /etc/init.d/php-fpm

查看phpinfo()

php7和php5性能分析比較
<?php
//time /usr/local/php5/bin/php search_by_key.php
$a = array();
    for($i=0;$i<600000;$i++){
        $a[$i] = $i;
        }

    foreach($a as $i)
    {
        array_key_exists($i, $a);
    }
?>
生成一个 60 万元素的数组,通过查找key 的方式。来确定key是否存在。



PHP 5.4.44 版
[root@localhost www5.4.44]# time /usr/local/php5.4.44/bin/php search_by_key.php

real    0m0.351s
user    0m0.300s

PHP 5.5.28 版
[root@localhost www]# time /usr/local/php/bin/php search_by_key.php
real    0m0.361s
user    0m0.304s
sys     0m0.057s

PHP 7.0.0 版
[root@localhost www7]# time /usr/local/php7/bin/php search_by_key.php
real    0m0.114s
user    0m0.097s
sys     0m0.017s

非常明显php7的性能是php5的3倍。

配置opcache
官网地址:http://php.net/opcache

使用下列推荐设置来获得较好的 性能:

opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=60
opcache.fast_shutdown=1
opcache.enable_cli=1

你也能够禁用 opcache.save_comments 而且启用 opcache.enable_file_override

须要提醒的是,在生产环境中使用上述配置之前。必须经过严格測试。 由于上述配置存在一个已知问题。它会引发一些框架和应用的异常。 尤其是在存在文档使用了备注注解的时候。 



vim /usr/local/php7/etc/php.ini
# 增加
zend_extension=/usr/local/php7/lib/php/extensions/no-debug-non-zts-20141001/opcache.so

重新启动

# killall php-fpm

#  /etc/init.d/php-fpm
