我最近开始在 ubuntu 上进行 Web 开发。
最初，我在 Ubuntu 12.04.3 LTS 上安装了 Zend 服务器。但后来我决定使用“lamp-server”，因此我通过运行以下命令卸载了 Zend 服务器
/usr/local/zend/bin/uninstall.sh
如图所示 http://files.zend.com/help/Zend-Server-6/content/deb_uninstalling_zend_server.htm
现在我想通过运行以下命令使用 taskel 安装 lamp 服务器
sudo tasksel install lamp-server
但我在安装时遇到了问题。当我在浏览器中访问 localhost 时，出现了错误页面。
任何帮助将不胜感激。

编辑2 看来 lamp-server 已正确安装，但是当我转到 localhost 时出现此错误“无法连接 Firefox 无法与 localhost 的服务器建立连接。”
我尝试重新启动 apache2，但sudo service apache2 restart只遇到此错误：

您必须按照以下顺序运行安装：
sudo apt-get updatesudo apt-get install taskselsudo tasksel install lamp-server
答案2
卸载 apache2 并重新安装。看来您的 apache2 配置文件有问题。运行以下命令：
sudo apt-get purge apache2 apache2-utils apache2.2-bin apache2-common
sudo apt-get autoremove
要确认它已被删除，请运行：which apache2它应该返回一个空白行，或者运行sudo service apache2 start它应该返回“apache2：无法识别的服务”
现在重新安装它，再次运行：
sudo apt-get install apache2
Localhost 现在应该可以正常工作。
