Nginx支持php脚本解释需要安装php-fpm进程管理器，在php5.3之前版本，php-fpm需要单独安装，之后版本php-fpm集成到PHP解释器之中，编译PHP解释器时需要特别指定配置，不同的PHP解释器版本编译经常出现兼容错误，在此可以成功编译php 7.2.15版本，其他版本(php 7.2.18)没有测试成功.

1. 下载php 7.2.15

wget php-7.2.15.tar.bz2 http://cn2.php.net/distributions/php-7.2.15.tar.bz2

2. 解压

tar -xjvf php-7.2.15.tar.bz

3. 安装YUM源

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-6.10.repo
yum clean all && yum makecache

4. 安装yum依赖

yum -y install wget vim pcre pcre-devel openssl openssl-devel libicu-devel gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel ncurses ncurses-devel curl curl-devel krb5-devel libidn libidn-devel openldap openldap-devel nss_ldap cmake boost-devel bison automake libevent libevent-devel gd gd-devel libtool* libxslt libxslt-devel readline readline-devel gmp gmp-devel libcurl libcurl-devel openjpeg-devel

5. 配置编译脚本

./configure
–prefix=/usr/local/php
–enable-fpm
–with-config-file-path=/usr/local/php/etc
–enable-mysqlnd
–with-mysqli=mysqlnd
–with-pdo-mysql=mysqlnd
–enable-pdo
–with-iconv-dir
–with-freetype-dir
–with-jpeg-dir
–with-png-dir
–with-zlib
–with-libxml-dir=
–enable-xml
–enable-session
–disable-rpath
–enable-bcmath
–enable-shmop
–enable-sysvsem
–enable-inline-optimization
–with-curl
–enable-mbregex
–enable-mbstring
–enable-intl
–enable-pcntl
–enable-ftp
–with-gd
–with-openssl
–with-mhash
–enable-pcntl
–enable-sockets
–with-xmlrpc
–enable-zip
–enable-soap
–with-gettext
–disable-fileinfo
–enable-opcache
–enable-maintainer-zts
–with-xsl
–enable-tokenizer

6. 编译并安装

make && make install

7.添加www用户

groupadd www
useradd -g www -s /sbin/nologin www

8.复制配置文件

cp php.ini-production /usr/local/php/etc/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

9.修改PHP的session文件存放目录

配置文件：/usr/local/php/etc/php.ini
session.save_path = “/usr/local/php/tmp”

10.修改PHP默认UTC时区改成中国时区

date.timezone = PRC

11.修改 php-fpm 用户组

配置文件：/usr/local/php/etc/php-fpm.d/www.conf
修改如下内容：
user = www
group = www

11.启动 php-fpm 服务

/usr/local/php/sbin/php-fpm

php-fpm服务端口是9000，在/usr/local/php/etc/php-fpm.d/www.conf中配置

12.Nginx配置

在server中添加如下

	root /php_site/;location ~ \.php$ {fastcgi_pass   127.0.0.1:9000;fastcgi_index  index.php;fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;include        fastcgi_params;}

13.修改网站目录属性

chmod -R 777 /php_site
