Comparison between PHP7 and HHVM

The performance of PHP7 in real scenarios is indeed comparable to that of HHVM Quite, even surpassing HHVM in some scenarios.

The operation and maintenance of HHVM is complicated and it is a multi-threaded model. This means that if a thread causes a crash, the entire service will hang up, and it will not automatically restart itself.

In addition, it uses JIT, which means that it needs to be warmed up after restarting. Without preheating, the performance will be worse. Moreover, the multi-threaded model is difficult to debug, which is very unsuitable for web services that pursue stability.

Download

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

It is recommended to read the installation help file INSTALL before installation

If the configuration is wrong, you need to install the necessary modules, directly yum to install the dependent libraries together

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

Note: When installing php7beta3, there are several configurations that you just need to yum. This is no longer the case with php-7.0.2.

# yum -y install curl-devel
# yum -y install libxslt-devel

Compile and install

# make &&  make install

Configuration file

# 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

Configuring environment variables

/etc/profile
export PATH=/usr/local/php/bin:$PATH

It should be noted that the www.conf configuration file in php7 configures the port number and other information of phpfpm. If you change the default 9000 The port number needs to be changed here, and then the nginx configuration

Start

#  /etc/init.d/php-fpm
