Mod_rewrite 已启用但不起作用

我已经阅读了一段时间，但无法让它发挥作用。

mod_rewrite 在 Apache 中启用，我已将 AllowOverride 更改为 all

我的 .htaccess 看起来像这样：

Options +FollowSymLinks
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ profile.php/?username=$1 [L]

我的 apache2 默认文件如下所示： ServerAdmin webmaster@localhost

    DocumentRoot /var/www
    <Directory />
            Options FollowSymLinks
            AllowOverride all
    </Directory>
    <Directory /var/www/>
            Options Indexes FollowSymLinks MultiViews
            AllowOverride all
            Order allow,deny
            allow from all
    </Directory>

    ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
    <Directory "/usr/lib/cgi-bin">
            AllowOverride None
            Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
            Order allow,deny
            Allow from all
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log

    # Possible values include: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel warn

    CustomLog ${APACHE_LOG_DIR}/access.log combined

在我的网站上，我收到 500 内部服务器错误消息。请帮忙！

尝试将您的代码更改为：

Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ profile.php/?username=$1 [L]

即转动MultiViews选项关闭。

PS:查看您的 error.log 看起来您之前的 .htaccess 中有一些特殊字符RewriteEngine关键词。
