Linux環境下PHP7.0的安裝方法

這篇文章將為大家詳細講解有關Linux環境下PHP7.0的安裝方法，小編覺得挺實用的，因此分享給大家做個參考，希望大家閱讀完這篇文章后可以有所收獲。

PHP7和HHVM比較
PHP7的在真實場景的性能確實已經和HHVM相當, 在一些場景甚至超過了HHVM。HHVM的運維復雜, 是多線程模型, 這就代表著如果一個線程導致crash了, 那么整個服務就掛了, 并且它不會自動重啟。另外它采用JIT, 那么意味著, 重啟以后要預熱, 沒有預熱的情況下, 性能較為糟糕。并且多線程模型調試困難, 這對于追求穩定來說的Web服務來說, 是非常不適合的。

Nginx以及PHP7.0之前的版本可以參考此文：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月份左右發布，目前是PHP7.0.2版本，本人最早是從2015年8月php7的第一個測試版跟起，現在正式版發布。

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

建議安裝之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

如果配置錯誤，需要安裝需要的模塊，直接yum一并安裝依賴庫

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，需要yum一下，現在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

需要注意的是php7中www.conf這個配置文件配置phpfpm的端口號等信息，如果你修改默認的9000端口號需在這里改，再改nginx的配置
啟動

/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); } ?>

生成一個 60 萬元素的數組，通過查找key 的方式，來確定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
[root@localhost www7]# time /usr/local/php7/bin/php search_by_key.php
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獲得較好的 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
你也可以禁用 opcache.save_comments 并且啟用 opcache.enable_file_override。 需要提醒的是，在生產環境中使用上述配置之前，必須經過嚴格測試。 因為上述配置存在一個已知問題，它會引發一些框架和應用的異常， 尤其是在存在文檔使用了備注注解的時候。

vim /usr/local/php7/etc/php.ini

加入

zend_extension=/usr/local/php7/lib/php/extensions/no-debug-non-zts-20141001/opcache.so

重啟

killall php-fpm

/etc/init.d/php-fpm

Opcache 狀態測試代碼(https://gist.github.com/ck-on/4959032)進行演示：

* 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
