Apache配置本地访问地址

本地要访问特定文件地址时，如果放在xampp的根目录里，找起来会特别麻烦。
如果将该文件夹映射到localhost里，相信就会方便很多，而且便于集中管理。

比如我的本地文件夹地址是D:\projects\test，在httpd.conf里，添加下面内容：

#映射地址为localhost/z
Alias /z "D:/projects"
&lt;Directory "D:/projects"&gt;
    Options Indexes FollowSymLinks Includes ExecCGI
    #如果不想列出目录则将上面一行换成下面一行
    #Options None 
    AllowOverride All
    Require all granted
&lt;/Directory&gt;

那么，就可以直接访问了。

Symfong Book 2.3 学习过程中遇到的一些问题

问题一

书中P47中，4-7这处的代码：

// src/Acme/DemoBundle/Controller/RandomController.php
namespace Acme\DemoBundle\Controller;
use Symfony\Component\HttpFoundation\Response;
class RandomController
{
public function indexAction($limit)
{
return new Response(
'&lt;html&gt;&lt;body&gt;Number: '.rand(1, $limit).'&lt;/body&gt;&lt;/html&gt;'
);
}
}

应当在前后加入<?php ?>标签

Ubuntu 14.04 环境下配置Symfony 2.3

首先，我们需要安装PHP5

$ sudo apt-get install php5
`</pre>

接下来

<pre>`$ curl -LsS http://symfony.com/installer &gt; symfony.phar
$ sudo mv symfony.phar /usr/local/bin/symfony
$ chmod a+x /usr/local/bin/symfony
`</pre>

接下来，我们需要安装2.3版本的Symfony

<pre>`$ symfony new my_project 2.3
`</pre>

过程可能会比较漫长。

安装提示成功以后，根据提示，输入

<pre>`$ php my_project/app/check.php
`</pre>

检查错误。

* * *

遇到的问题：

1.data.timezone()

运行

<pre>`$ locate php.ini
`</pre>

查找php.ini地址，找到timezone具体行数，将前面的注释取消，输入

<pre>`date.timezone = Asia/Chongqing
`</pre>

具体timezone参考[这里](http://php.net/manual/zh/timezones.asia.php)

2.WARNING  intl extension should be available

          Install and enable the intl extension (used for validators).

输入命令：

<pre>`$ sudo apt-get install php5-intl
`</pre>

3.WARNING  PDO should have some drivers installed (currently available: none)

          Install PDO drivers (mandatory for Doctrine).

输入命令：

<pre>`$ sudo apt-get install php5-mysql

修改Chrome默认搜索引擎为Google.com

关闭所有的Chrome窗口
进入Chrome的用户设置文件夹，对于Windows Vista和Windows 7用户进入已经变为了 %LOCALAPPDATA%\Google\Chrome\User Data\Default\Preferences3. 用记事本打开Preferences文件
找到last_known_google_url和 last_prompted_google_url这两行，修改为Google.com，或者其它你想用的Google本地化搜索域名.
保存文件，重新打开Chrome，即可看到变化.
