此配置的编译参数是：
./configure --prefix=/opt/php7.2.3 --with-openssl --with-zlib --with-curl --enable-ftp --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --enable-mbstring --with-libxml-dir --enable-soap --enable-sockets --with-xmlrpc --with-iconv-dir=/opt/libiconv --with-xsl --with-mysqli --with-pdo-mysql --enable-zip --enable-fpm --with-fpm-user=USER --with-fpm-group=GRP
php的配置文件：
[root@cairui php]# cd etc/ [root@cairui etc]# ls pear.conf php-fpm.conf.default php-fpm.d
注：对apache来说php是没有进程的，它只是一个模块，在服务配置文件中配置模块支持就可以了，但对于nginx来说，php是有进程的，而它是依靠fastcgi来运行，所以配置和apache的不同。

php官网的推荐安装：
Unix 系统下的 Nginx 1.4.x
本文档包括使用 PHP-FPM 为 Nginx 1.4.x HTTP 服务器安装和配置 PHP 的说明和提示。
本指南假定您已经从源代码成功构建 Nginx，并且其二进制文件和配置文件都位于 /usr/local/nginx。 如果您使用其他方式获取的 Nginx，请参考 » Nginx Wiki 并对照本文档完成安装。
本文档仅包含 Nginx 服务器的基本配置，它将通过 80 端口提供 PHP 应用的处理能力。 如果您需要超出本文档范围的安装配置指导，建议您查阅 Nginx 和 PHP-FPM 的文档。
需要注意的是，本文档一律使用 'x' 来表示版本号，请根据实际情况将 'x' 替换为对应的版本号。
建议您访问 Nginx Wiki » 安装 页面以获取并在您的系统上安装 Nginx。
获取并解压 PHP 源代码:
tar zxf php-x.x.x
配置并构建 PHP。在此步骤您可以使用很多选项自定义 PHP，例如启用某些扩展等。 运行 ./configure --help 命令来获得完整的可用选项清单。 在本示例中，我们仅进行包含 PHP-FPM 和 MySQL 支持的简单配置。
cd ../php-x.x.x
./configure --enable-fpm --with-mysql
make
sudo make install
创建配置文件，并将其复制到正确的位置。
cp php.ini-development /usr/local/php/php.ini
cp /usr/local/etc/php-fpm.conf.default /usr/local/etc/php-fpm.conf
cp sapi/fpm/php-fpm /usr/local/bin
需要着重提醒的是，如果文件不存在，则阻止 Nginx 将请求发送到后端的 PHP-FPM 模块， 以避免遭受恶意脚本注入的攻击。
将 php.ini 文件中的配置项 cgi.fix_pathinfo 设置为 0 。
打开 php.ini:
vim /usr/local/php/php.ini
定位到 cgi.fix_pathinfo= 并将其修改为如下所示：
cgi.fix_pathinfo=0
在启动服务之前，需要修改 php-fpm.conf 配置文件，确保 php-fpm 模块使用 www-data 用户和 www-data 用户组的身份运行。
vim /usr/local/etc/php-fpm.conf
找到以下内容并修改：
; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
; will be used.
user = www-data
group = www-data
然后启动 php-fpm 服务：
/usr/local/bin/php-fpm
本文档未涵盖对 php-fpm 进行进一步配置的信息，如果您需要更多信息，请查阅相关文档。
配置 Nginx 使其支持 PHP 应用：
vim /usr/local/nginx/conf/nginx.conf
修改默认的 location 块，使其支持 .php 文件：
location / {
root html;
index index.php index.html index.htm;
}
下一步配置来保证对于 .php 文件的请求将被传送到后端的 PHP-FPM 模块， 取消默认的 PHP 配置块的注释，并修改为下面的内容：
location ~* .php$ {
fastcgi_index index.php;
fastcgi_pass 127.0.0.1:9000;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
}
重启 Nginx。
sudo /usr/local/nginx/sbin/nginx -s stop
sudo /usr/local/nginx/sbin/nginx
创建测试文件。
rm /usr/local/nginx/html/index.html
echo "<?php phpinfo(); ?>" >> /usr/local/nginx/html/index.php
打开浏览器，访问 http://localhost，将会显示 phpinfo() 。
通过以上步骤的配置，Nginx 服务器现在可以以 SAPI 模块的方式支持 PHP 应用了。 当然，对于 Nginx 和 PHP 的配置，还有很多可用的选项， 请在对应的源代码目录执行 ./configure --help 来查阅更多配置选项。
