php7发布已经有一段时间了,运行性能与HHVM不相上下,甚至在某些环境下超越了HHVM。鸟哥是php7的主要开发者之一,关于php7的来龙去脉大家可以看这篇文章:鸟哥:写在PHP7发布之际一些话。php7的新特性看这篇文章:migration70.new-features
准备工作
安装一些依赖库文件
yum groupinstall "Development tools"
yum install libxml2-devel gd-devel libmcrypt-devel libcurl-devel openssl-devel
安装php7
可以在php的官网上找到不同的版本下载链接。
//下载
wget http://cn2.php.net/distributions/php-7.0.5.tar.gz
//解压
tar -zxvf php-7.0.5.tar.gz
cd php-7.0.5
配置,安装在/usr/local/php7这个路径
./configure --prefix=/usr/local/php7 \
--with-curl \
--with-freetype-dir \
--with-gd \
--with-gettext \
--with-iconv-dir \
--with-kerberos \

编译
make
安装
make install
安装成功后,可以看到类似下面的输出

You may want to add: /usr/local/php/lib/php to your php.ini include_path
/tmp/php-7.0.5/build/shtool install -c ext/phar/phar.phar /usr/local/php/bin
ln -s -f phar.phar /usr/local/php/bin/phar
Installing PDO headers: /usr/local/php/include/php/ext/pdo/
可以查找一下libphp7.so文件,看看是否生成
[root@hellojammy ~]# find / -name *php7*.so
/usr/lib64/httpd/modules/libphp7.so
[root@hellojammy ~]# php -version
PHP 7.0.5 (cli) (built: Apr 12 2016 13:30:14) ( NTS )
Copyright (c) 1997-2016 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies
with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies
可见已经生成了libphp7.so。查看版本也是php7.0.5。
配置
配置文件。在php的编译目录,执行以下命令。
cp php.ini-development /usr/local/php7/lib/php.ini
查看apache的配置文件是否已经开启关联(一般情况下,安装完php后,会开启,假如没有开启则开启)
vim /usr/local/apache/conf/httpd.conf
LoadModule php5_module /usr/lib64/httpd/modules/libphp7.so
加入以下代码:
<FilesMatch \.php$>
SetHandler application/x-httpd-php
</FilesMatch>
更改一下代码:
DirectoryIndex index.html index.shtml index.cgi index.php index.phtml index.php3
找到AddType处,并添加以下2行:
AddType application/x-httpd-php .php .php3 .phtml .inc
AddType application/x-httpd-php-source .phps
注意事项
编译php7可能遇到的问题之一是无法生成libphp7.so文件,这可以做以下检查:
1、检查configure是不是缺少一个 --with-apxs2 ,添加一下
2、然后确认apache配置文件httpd.conf中是否含有以下配置:
<FilesMatch .php$>
SetHandler application/x-httpd-php
</FilesMatch>
如果有,则进行第3�步,不然添加一下
3、重新 ./configure + 参数 make make install,重新安装安装一下,记得加--with-apxs2。
无法生成libphp7.so的解决方案,参考了知乎的这篇文章
