在全新安装上安装 PHP 5

Question

我全新安装了Ubuntu 10.10 (Maverick Meerkat)，我想让 PHP 工作。我试过了

sudo apt-get install apache2
sudo apt-get install php5
sudo apt-get install libapache2-mod-php5
sudo /etc/init.d/apache2 restart

但是当我导航到http://localhost/ 时，我看到的只是 Firefox 错误页面，上面写着“无法连接”。

此外，当我尝试http://localhost/test.php 时，浏览器会询问我是否要下载该文件，而不是执行 PHP 文件。

这是 error.log 文件内容：

Answer 1

您可以运行一个命令来安装LAMP：

安装中的tasksel

选择 LAMP 服务器，

按照安装过程进行。

安装完成后，您可以按照您的方式测试您的本地主机。

检查 PHP 是否正常工作

sudo   gedit  /var/www/info.php

并粘贴此 PHP 信息代码：

<?php
    phpinfo();
?>

保存并退出。

重启 Apache 2：

sudo /etc/init.d/apache2  restart

您可以测试运行 info.php 文件的 PHP：

http://localhost/info.php

Answer 2

http://netbeans.org/kb/docs/php/configure-php-environment-ubuntu.html中列出的步骤正是我所需要的。我全新安装了 Ubuntu，运行

sudo tasksel 安装灯服务器

然后按照故障排除部分中的步骤即

apt-get --purge 删除 php5-common

apt-get install php5 phpmyadmin
