실제 시나리오에서 PHP7의 성능은 실제로 HHVM과 비슷하며 일부 시나리오에서는 HHVM을 초과하기도 합니다. HHVM의 운영 및 유지 관리는 복잡하며 다중 스레드 모델입니다. 즉, 하나의 스레드가 충돌을 일으키면 전체 서비스가 중단되고 자동으로 다시 시작되지 않습니다. 또한 JIT를 사용하는데, 이는 다시 시작한 후 예열이 필요하다는 것을 의미합니다. 예열하지 않으면 성능이 저하됩니다. 게다가 멀티스레드 모델은 디버깅이 어려워 안정성을 추구하는 웹 서비스에는 매우 부적합하다.

Nginx 및 PHP7.0 이전 버전은 다음 기사를 참조할 수 있습니다: Linux 환경 Nginx 설치 및 디버깅 및 PHP 설치

PHP7.0의 공식 버전은 2015년 11월쯤 출시되었습니다. 현재는 PHP7.0.2 버전입니다. 2015년 8월 php7의 첫 번째 베타 버전을 시작으로 이제 정식 버전이 출시되었습니다.

linux 버전: 64비트 CentOS 6.6

Nginx 버전: nginx1.8.0

php 버전: php-7.0.2

Download

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

설치하기 전에 설치 도움말 파일을 읽는 것이 좋습니다

압축을 풀고 설치하세요

# tar zxvf php-7.0.2.tar.gz

# cd php-7.0 .2

먼저 설치 도움말을 확인하세요

# ./configure --help

# ./configure --prefix=/usr/local/php
--with-curl
--with-freetype-dir
- -with-gd
--with-gettext
--with-iconv-dir
--with-kerberos
--with-libdir=lib64
--with-libxml-dir
--with-mysqli
--with -openssl
-- with-pcre-regex
--with-pdo-mysql
--with-pdo-sqlite
--with-pear
--with-png-dir
--with-xmlrpc
--with -xsl
-- with-zlib
--enable-fpm
--enable-bcmath
--enable-libxml
--enable-inline-optimization
--enable-gd-native-ttf
--enable-mbregex
--enable- mbstring
--enable-opcache
--enable-pcntl
--enable-shmop
--enable-soap
--enable-sockets
--enable-sysvsem
--enable-xml
- -enable-zip

구성이 잘못된 경우 필요한 모듈을 설치하고 yum

# yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2로 직접 종속 라이브러리를 설치해야 합니다. libxml2-devel mysql pcre-devel

참고: php7beta3을 설치할 때 구성할 수 없는 몇 가지 구성이 있습니다. php-7.0.2에서는 더 이상 그렇지 않습니다.

# yum -y install 컬-devel

# yum -y install libxslt-devel

컴파일 및 설치

# make && make install



구성 파일

# 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

php7의 www.conf 구성 파일은 phpfpm의 포트 번호 및 기타 정보를 구성한다는 점에 유의해야 합니다. 기본 9000 포트 번호를 수정하려면 변경해야 합니다. 여기에서 nginx로 변경하세요. Configuration

Startup
# /etc/init.d/php-fpm

php7과 php5 성능 분석 비교

<?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);
    }
?>

600,000개 요소의 배열을 생성하고, 키를 검색하여 키가 존재하는지 확인합니다.

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

real 0m0.351s
user 0m0.300s
sys 0m0 . 050s


PHP 버전 5.5.28
[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 버전
[root@localhost www7]# time /usr/local/php7/bin/php search_by_key.php
real 0m0.114s
user 0m0.097s
sys 0m0.017s

성능이 확실한 것은 php7은 php5 3번입니다!

opcache 구성
공식 웹사이트 주소: http://php.net/opcache

더 나은 성능을 얻으려면 다음 권장 설정을 사용하세요.

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

你也可以禁用 opcache.save_comments 并且启用 opcache.enable_file_override。 需要提醒的是,在生产环境中使用上述配置之前,必须经过严格测试。 因为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
# 加入
zend_extension=/usr/local/php7/lib/php/extensions/no-debug-non-zts-20141001/opcache.so

重启

# killall php-fpm

#  /etc/init.d/php-fpm

OCP - Opcache Control Panel (aka Zend Optimizer+ Control Panel for PHP)
Author: _ck_ (with contributions by GK, stasilok)
Version: 0.1.6
Free for any kind of use or modification, I am not responsible for anything, please share your improvements
 
* revision history
0.1.6 2013-04-12 moved meta to footer so graphs can be higher and reduce clutter
0.1.5 2013-04-12 added graphs to visualize cache state, please report any browser/style bugs
0.1.4 2013-04-09 added "recheck" to update files when using large revalidate_freq (or validate_timestamps=Off)
0.1.3 2013-03-30 show host and php version, can bookmark with hashtag ie. #statistics - needs new layout asap
0.1.2 2013-03-25 show optimization levels, number formatting, support for start_time in 7.0.2
0.1.1 2013-03-18 today Zend completely renamed Optimizer+ to OPcache, adjusted OCP to keep working
0.1.0 2013-03-17 added group/sort indicators, replaced "accelerator_" functions with "opcache_"
0.0.6 2013-03-16 transition support as Zend renames product and functions for PHP 5.5 (stasilok)
0.0.5 2013-03-10 added refresh button (GK)
0.0.4 2013-02-18 added file grouping and sorting (click on headers) - code needs cleanup but gets the job done
0.0.2 2013-02-14 first public release
 
* known problems/limitations:
Unlike APC, the Zend OPcache API
- cannot determine when a file was put into the cache
- cannot change settings on the fly
- cannot protect opcache functions by restricting execution to only specific scripts/paths
 
* todo:
Extract variables for prefered ordering and better layout instead of just dumping into tables
File list filter
