与nginx搭配使用的php，有三个配置文件：php.ini、php-fpm.conf、www.conf。
php.ini是php运行时的核心配置。cli形式、php-fpm模式下的php进程，都读取php.ini中的配置项。  （推荐学习：php视频教程）
php-fpm.conf 是php-fpm管理下的php进程的配置文件。该模式下运行的php进程，除读取php.ini中的配置项外，
还读取php-fpm.conf中的配置项。
www.conf 是 php-fpm.conf 的补充。
php.ini中的重要配置
######避免php信息暴露在http头中expose_php = off######避免暴露php错误信息display_errors = off######在关闭display_errors后开启php错误日志（路径在php-fpm.conf中配置）log_errors = on######设置php的扩展库路径extension_dir = "/usr/local/php7/lib/php/extensions/no-debug-non-zts-20141001/"######设置php的opcache和mysql动态库zend_extension=opcache.soextension=mysqli.soextension=pdo_mysql.so######设置php的时区date.timezone = prc######开启opcache[opcache]; determines if zend opcache is enabledopcache.enable=1######设置php脚本允许访问的目录（需要根据实际情况配置）;open_basedir = /usr/share/nginx/html;
php-fpm.conf中的重要配置
;php运行日志error_log=log/php-fpm.log;fpm使用的事件机制events.mechanism = epoll;php-fpm.conf的补充文件www.conf的路径include=/usr/cg/lnmp/php-7.0.13/etc/php-fpm.d/*.conf
www.conf的重要配置
