本文详细介绍了在Apache2中使用别名(alias)时，如何正确配置.htaccess以避免404错误。通过添加RewriteBase和调整选项设置，确保重写规则正常工作。

当在apache2中使用别名时，配置.htaccess会遇到404错误。
比如以下的alias配置：

Alias /htdocs /home/faund/yiidev/htdocs/wwwroot/
<Directory /home/faund/yiidev/htdocs/wwwroot/>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
Allow from all
Require all granted
</Directory>

在/home/faund/yiidev/htdocs/wwwroot/下创建.htaccess内容如下：

<ifModule mod_rewrite.c>
# Turn on the engine:
RewriteEngine on

# Don't perform redirects for files and directories that exist:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# For everything else, redirect to index.php:
RewriteRule ^(.*)$ index.php/$1
</ifModule>

结果会出现404错误。

Not Found

The requested URL /home/faund/yiidev/htdocs/wwwroot/index.php/site/login was not found on this server.

此时需要RewriteBase, 后面跟上Alias的web路径，如下面粗体部分：

<ifModule mod_rewrite.c>
# Turn on the engine:
RewriteEngine on
RewriteBase /htdocs

# Don't perform redirects for files and directories that exist:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# For everything else, redirect to index.php:
RewriteRule ^(.*)$ index.php/$1
</ifModule>

如果此时仍旧出现错误，可以到apache的log中查看原因。如果出现402禁止访问的错误，可以在error_log中查看到这样的错误：

[Sat Apr 12 19:05:37.417862 2014] [rewrite:error] [pid 12639] [client ::1:53474] AH00670: Options FollowSymLinks and SymLinksIfOwn

这果需要在.htaccess文件中增加“Options +FollowSymlinks”

Options +FollowSymlinks
<ifModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

#RewriteBase /yiidev

RewriteRule ^(.*)$ /yiidev/webapp/larry_book/public_html/index.php/$1
</ifModule>
