问题描述
Ubuntu 16.04 升级后，Apache 将 PHP 文件呈现为文本。
Apache 已安装并正在运行。\nPHP7 正在运行。当我执行以下命令时，我得到正确的输出：
php -r 'echo "\n\nYour PHP installation is working fine.\n\n\n";'
但是，当我访问 http://localhost/info.php 或任何其他 php 文件时，我得到的是文件内容而不是页面。
大多数在线帮助都是针对旧版本的 Ubuntu 和 PHP，因此我不确定它们是否可靠。
更新：\n安装 libapache2-mod-php7.0 并启用 php7.0 后，Apache 将无法启动。查看输出：
douglas@douglas-acer:~$ sudo service apache2 restart
douglas@douglas-acer:~$ sudo apt-get install libapache2-mod-php

关于错误 Apache is running a threaded MPM, but your PHP Module is not compiled to be threadsafe. You need to recompile PHP 我确实在 https://wiki.archlinux.org/index.php/Apache_HTTP_Server 中找到了有关此问题的一些帮助，但是文件路径与 Ubuntu 中的文件路径不匹配，因此我没有尝试应用建议的修复。
最佳回答
php 命令由 Ubuntu 16.04 上的 php7.0-cli 软件包提供。运行 CLI 与 Web 服务器配置正交。
您需要安装并配置 Web SAPI 之一 – apache2、fpm 或 cgi。最简单的是安装apache2 SAPI。
-
要安装 apache2 SAPI，请运行
apt-get install libapache2-mod-php(这将拉取默认的 PHP 版本，当前为libapache2-mod-php7.0)。该软件包应自行启用并切换到 apache2 prefork MPM，这是唯一受支持的 MPM。如果没有，请尝试运行a2enmod php7.0并查找错误。安装应该自动从事件 MPM 切换到预分叉 MPM，但如果没有，您可以通过执行sudo a2dismod mpm_event和sudo a2enmod mpm_prefork来手动切换。 -
要安装 FPM SAPI，请运行
apt-get install php-fpm，然后通过运行a2enconf php7.0-fpm启用 FPM。 FPM SAPI 更安全，但更难正确配置。 -
要安装 CGI SAPI，请运行
apt-get install php-cgi，然后通过运行a2enconf php7.0-cgi启用 CGI。请注意，不推荐使用 CGI 来运行 PHP，但它在特殊部署中可能会派上用场。
