Linux环境如何安装PHP7.0

本篇文章给大家介绍一下Linux环境安装PHP7.0的方法。有一定的参考价值，有需要的朋友可以参考一下，希望对大家有所帮助。

PHP7和HHVM比较

PHP7的在真实场景的性能确实已经和HHVM相当, 在一些场景甚至超过了HHVM。HHVM的运维复杂, 是多线程模型, 这就代表着如果一个线程导致crash了, 那么整个服务就挂了, 并且它不会自动重启。另外它采用JIT, 那么意味着, 重启以后要预热, 没有预热的情况下, 性能较为糟糕。并且多线程模型调试困难, 这对于追求稳定来说的Web服务来说, 是非常不适合的。

Nginx以及PHP7.0之前的版本可以参考此文：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，本人最早是从2015年8月php7的第一个测试版跟起，现在正式版发布。

linux版本：64位CentOS 6.6

Nginx版本：nginx1.8.0

php版本：php-7.0.2

下载

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

建议安装之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

# ./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

如果配置错误，需要安装需要的模块，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，需要yum一下，现在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

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这个配置文件配置phpfpm的端口号等信息，如果你修改默认的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()

php7和php5性能分析比较

<?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);
    }
?>

生成一个 60 万元素的数组，通过查找key 的方式，来确定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获得较好的 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

重启

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

如果上图不太明白，可以使用文末Opcache 状态测试代码(https://gist.github.com/ck-on/4959032)进行演示：
