本地开发设置中 Apache 虚拟主机的连接被拒绝 [重复]

我需要使用特定版本的 PHP (7.1) 设置本地 LAMP。在全新安装的 18.04 中，我首先安装了 Apache 和 MySQL。然后我按照本指南从 ppa:ondrej/php 安装 PHP 并完成安装 phpMyAdmin，它工作正常。

我的 php 安装是

sudo apt install php7.1 libapache2-mod-php7.1 php7.1-mysql php7.1-mbstring

对于我的站点测试，我运行了一个在 16.04 上对我有用的虚拟主机脚本。一切看起来都有效，除了手动必须 chown public_html 目录。我的问题是，尝试在 info.dev 访问我的测试文件会返回页面错误info.dev refused to connect.和ERR_CONNECTION_REFUSED.

PHP 似乎正在工作，因为我成功地infophp()从 apache 测试页面调用。

有人可以提出一些建议吗？
