PHP7和HHVM比较
PHP7的在真实场景的性能确实已经和HHVM至关, 在一些场景甚至超过了HHVM。HHVM的运维复杂, 是多线程模型, 这就表明着若是一个线程致使crash了, 那么整个服务就挂了, 而且它不会自动重启。另外它采用JIT, 那么意味着, 重启之后要预热, 没有预热的状况下, 性能较为糟糕。而且多线程模型调试困难, 这对于追求稳定来讲的Web服务来讲, 是很是不适合的。javascript

Nginx以及PHP7.0以前的版本能够参考此文:Linux环境Nginx安装与调试以及PHP安装php


PHP7.0正式版已经在2015年11月份左右发布,目前是PHP7.0.2版本,本人最先是从2015年8月php7的第一个测试版跟起,如今正式版发布。css

linux版本:64位CentOS 6.6html

Nginx版本:nginx1.8.0java

php版本:php-7.0.2mysql


下载linux

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


建议安装以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

若是配置错误,须要安装须要的模块,直接yum一并安装依赖库git
# yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel MySQL pcre-develgithub



注意:安装php7beta3的时候有几处配置不过去,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
d013f104035e486ca1d08a32.jpg


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,若是你修改默认的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()

很明显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得到较好的 性能:
  1. opcache.memory_consumption=128
  2. opcache.interned_strings_buffer=8
  3. opcache.max_accelerated_files=4000
  4. opcache.revalidate_freq=60
  5. opcache.fast_shutdown=1
  6. opcache.enable_cli=1
复制代码
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以前,必须通过严格测试。 由于上述配置存在一个已知问题,它会引起一些框架和应用的异常, 尤为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

  4. OCP - Opcache Control Panel (aka Zend Optimizer+ Control Panel for PHP)
  5. Author: _ck_ (with contributions by GK, stasilok)
  6. Version: 0.1.6
  7. Free for any kind of use or modification, I am not responsible for anything, please share your improvements
  8.   
  9. * revision history
  10. 0.1.6 2013-04-12 moved meta to footer so graphs can be higher and reduce clutter
  11. 0.1.5 2013-04-12 added graphs to visualize cache state, please report any browser/style bugs
  12. 0.1.4 2013-04-09 added "recheck" to update files when using large revalidate_freq (or validate_timestamps=Off)
  13. 0.1.3 2013-03-30 show host and php version, can bookmark with hashtag ie. #statistics - needs new layout asap
  14. 0.1.2 2013-03-25 show optimization levels, number formatting, support for start_time in 7.0.2
  15. 0.1.1 2013-03-18 today Zend completely renamed Optimizer+ to OPcache, adjusted OCP to keep working
  16. 0.1.0 2013-03-17 added group/sort indicators, replaced "accelerator_" functions with "opcache_"
  17. 0.0.6 2013-03-16 transition support as Zend renames product and functions for PHP 5.5 (stasilok)
  18. 0.0.5 2013-03-10 added refresh button (GK)
  19. 0.0.4 2013-02-18 added file grouping and sorting (click on headers) - code needs cleanup but gets the job done
  20. 0.0.2 2013-02-14 first public release
  21.   
  22. * known problems/limitations:
  23. Unlike APC, the Zend OPcache API
  24. - cannot determine when a file was put into the cache
  25. - cannot change settings on the fly
  26. - cannot protect opcache functions by restricting execution to only specific scripts/paths
  27.   
  28. * todo:
  29. Extract variables for prefered ordering and better layout instead of just dumping into tables
  30. File list filter

PHP7和HHVM比较
PHP7的在真实场景的性能确实已经和HHVM至关, 在一些场景甚至超过了HHVM。HHVM的运维复杂, 是多线程模型, 这就表明着若是一个线程致使crash了, 那么整个服务就挂了, 而且它不会自动重启。另外它采用JIT, 那么意味着, 重启之后要预热, 没有预热的状况下, 性能较为糟糕。而且多线程模型调试困难, 这对于追求稳定来讲的Web服务来讲, 是很是不适合的。
Nginx以及PHP7.0以前的版本能够参考此文: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月份左右发布,目前是PHP7.0.2版本,本人最先是从2015年8月php7的第一个测试版跟起,如今正式版发布。
linux版本:64位CentOS 6.6
Nginx版本:nginx1.8.0
php版本:php-7.0.2

若是配置错误,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的时候有几处配置不过去,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
d013f104035e486ca1d08a32.jpg


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,若是你修改默认的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()

很明显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得到较好的 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以前,必须通过严格测试。 由于上述配置存在一个已知问题,它会引起一些框架和应用的异常, 尤为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


若是上图不太明白,能够使用文末Opcache 状态测试代码(https://gist.github.com/ck-on/4959032)进行演示:

  6. Version: 0.1.6
  7. Free for any kind of use or modification, I am not responsible for anything, please share your improvements
  8.   
  9. * revision history
  10. 0.1.6 2013-04-12 moved meta to footer so graphs can be higher and reduce clutter
  11. 0.1.5 2013-04-12 added graphs to visualize cache state, please report any browser/style bugs
  12. 0.1.4 2013-04-09 added "recheck" to update files when using large revalidate_freq (or validate_timestamps=Off)
  13. 0.1.3 2013-03-30 show host and php version, can bookmark with hashtag ie. #statistics - needs new layout asap
  14. 0.1.2 2013-03-25 show optimization levels, number formatting, support for start_time in 7.0.2
  15. 0.1.1 2013-03-18 today Zend completely renamed Optimizer+ to OPcache, adjusted OCP to keep working
  16. 0.1.0 2013-03-17 added group/sort indicators, replaced "accelerator_" functions with "opcache_"
  17. 0.0.6 2013-03-16 transition support as Zend renames product and functions for PHP 5.5 (stasilok)
  18. 0.0.5 2013-03-10 added refresh button (GK)
  19. 0.0.4 2013-02-18 added file grouping and sorting (click on headers) - code needs cleanup but gets the job done
  20. 0.0.2 2013-02-14 first public release
  21.   
  22. * known problems/limitations:
  23. Unlike APC, the Zend OPcache API
  24. - cannot determine when a file was put into the cache
  25. - cannot change settings on the fly
  26. - cannot protect opcache functions by restricting execution to only specific scripts/paths
  27.   
  28. * todo:
  29. Extract variables for prefered ordering and better layout instead of just dumping into tables
  30. File list filter
