我的系统操作系统是MacOS10.13. 默认的 PHP 版本是7.1.16.
我phpbrew用来管理 PHP 版本。我安装了 php5.6。当我使用命令时phpbrew switch php5.6。然后我使用命令php -v
然后它输出：
PHP 5.6.30 (cli) (built: May 14 2019 18:30:16)
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
然后我使用命令php-fpm -v
输出：
PHP 7.1.16 (fpm-fcgi) (built: Mar 31 2018 03:00:16)
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2018 Zend Technologies
终端中的php版本是php5.6，web中的版本是php7.1
php-fpm 默认路径在/usr/sbin.
当我尝试替换php-fpm时，网页是404。nginxerror.log在这里。
