Linux環境PHP7.0安裝

PHP7和HHVM比較
PHP7的在真實場景的性能確實已經和HHVM至關, 在一些場景甚至超過了HHVM。HHVM的運維複雜, 是多線程模型, 這就表明着若是一個線程致使crash了, 那麼整個服務就掛了, 而且它不會自動重啓。另外它採用JIT, 那麼意味着, 重啓之後要預熱, 沒有預熱的狀況下, 性能較爲糟糕。而且多線程模型調試困難, 這對於追求穩定來講的Web服務來講, 是很是不適合的。

 

Nginx以及PHP7.0以前的版本能夠參考此文：Linux環境Nginx安裝與調試以及PHP安裝

 

PHP7.0正式版已經在2015年11月份左右發佈，目前是PHP7.0.2版本，本人最先是從2015年8月php7的第一個測試版跟起，如今正式版發佈。

linux版本：64位CentOS 6.6

Nginx版本：nginx1.8.0

php版本：php-7.0.2

 

下載

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

 

建議安裝以前先看看安裝幫助文件INSTALL

 

解壓安裝

# tar zxvf php-7.0.2.tar.gz

# cd php-7.0.2

首先查看安裝幫助

# ./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

 

若是配置錯誤，須要安裝須要的模塊，直接yum一併安裝依賴庫

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

 

注意：安裝php7beta3的時候有幾處配置不過去，須要yum一下，如今php-7.0.2已經不用這樣了。

# yum -y install curl-devel

# yum -y install libxslt-devel

 

編譯安裝

# 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

 

須要注意的是php7中www.conf這個配置文件配置phpfpm的端口號等信息，若是你修改默認的9000端口號需在這裏改，再改nginx的配置

啓動
#  /etc/init.d/php-fpm

 

查看phpinfo()





php7和php5性能分析比較

[php] view plain copy

1. <?php  
2. //time /usr/local/php5/bin/php search_by_key.php  
3. $a = array();  
4.     for($i=0;$i<600000;$i++){  
5.         $a[$i] = $i;  
6.         }  
7.   
8.     foreach($a as $i)  
9.     {  
10.         array_key_exists($i, $a);  
11.     }  
12. ?>  

生成一個 60 萬元素的數組，經過查找key 的方式，來肯定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
sys     0m0.050s

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

real    0m0.114s
user    0m0.097s
sys     0m0.017s

 

很明顯php7的性能是php5的3倍！

 

配置opcache
官網地址：http://php.net/opcache

使用下列推薦設置來得到較好的 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

你也能夠禁用 opcache.save_comments 而且啓用 opcache.enable_file_override。 須要提醒的是，在生產環境中使用上述配置以前，必須通過嚴格測試。 由於上述配置存在一個已知問題，它會引起一些框架和應用的異常， 尤爲是在存在文檔使用了備註註解的時候。 

 

 

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

重啓

# 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
