Die Leistung von PHP7 in realen Szenarien ist tatsächlich mit der von HHVM vergleichbar und übertrifft in einigen Szenarien sogar die von HHVM. Der Betrieb und die Wartung von HHVM sind komplex und es handelt sich um ein Multithread-Modell. Das bedeutet, dass der gesamte Dienst hängen bleibt und nicht automatisch neu gestartet wird. Darüber hinaus verwendet es JIT, was bedeutet, dass es nach dem Neustart aufgewärmt werden muss. Ohne Vorheizen wird die Leistung schlechter. Darüber hinaus ist das Multithread-Modell schwer zu debuggen, was für Webdienste, die Stabilität anstreben, sehr ungeeignet ist.

Für Versionen vor Nginx und PHP7.0 lesen Sie bitte diesen Artikel: Installation und Debugging von Nginx in der Linux-Umgebung und PHP-Installation

Die offizielle Version von PHP7.0 wurde etwa im November 2015 veröffentlicht. und ist derzeit die PHP7.0.2-Version. Ich habe im August 2015 erstmals damit begonnen, die erste Beta-Version von PHP7 zu verfolgen, und jetzt ist die offizielle Version veröffentlicht.

Linux-Version: 64-Bit CentOS 6.6

Nginx-Version: nginx1.8.0

PHP-Version: php-7.0.2

Download

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

Es wird empfohlen, die Installationshilfedatei INSTALL zu lesen

Entpacken und installieren

# tar zxvf php-7.0.2.tar.gz

# cd php-7.0.2

Zuerst die Installationshilfe prüfen

# ./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

Wenn die Konfiguration falsch ist, müssen Sie die erforderlichen Module direkt installieren Installieren Sie die abhängigen Bibliotheken zusammen

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

Hinweis: Es gibt mehrere Konfigurationen, bei denen dies nicht möglich ist muss bei der Installation von php7beta3 konfiguriert werden. Dies ist bei php-7.0.2 nicht mehr der Fall.

# yum -y install curl-devel

# yum -y install libxslt-devel

Kompilieren und installieren

# make && make install



Konfigurationsdatei

# 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

Es ist zu beachten, dass die Konfigurationsdatei www.conf in php7 die Portnummer und andere Informationen von phpfpm konfiguriert. Wenn Sie die Standardportnummer 9000 ändern, müssen Sie diese hier ändern , und ändern Sie dann die Nginx-Konfiguration

Start

# /etc/init.d/php-fpm

Vergleich der Leistungsanalyse von PHP7 und PHP5

<?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);
    }
?>
Nach dem Login kopieren
Generieren Sie ein Array mit 600.000 Elementen und bestimmen Sie, ob der Schlüssel vorhanden ist durch die Suche nach dem Schlüssel.



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

Offensichtlich ist die Leistung von PHP7 die von PHP5 dreimal!

Opcache konfigurieren

Offizielle Website-Adresse: http://php.net/opcache

Verwenden Sie die folgenden empfohlenen Einstellungen, um eine bessere Leistung zu erzielen:

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
Nach dem Login kopieren

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
