apache2反向代理配置

Question

我有一个侦听 TCP 127.0.0.1:81 的应用程序。我想完成以下重定向：

www.example.com/?requestid=123456 --> http://127.0.0.1:81/?requestid=123456
www.example.com/ANYTHING_ELSE --> MY_IP_THAT_APACHE_LISTENS_ON

我的理解是，如果我不显式重写某些内容，它将遵循通往 /var/www/html 的常规路径。

我的 /etc/apache2/sites-enabled/000-default.conf 配置：

<VirtualHost *:80>
        ServerName example.com
        ServerAdmin example@example.com
        DocumentRoot /var/www/html
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

    <Location />
        RewriteEngine On
        RewriteRule ^/?requestid(.*)$ http://127.0.0.1:81/ [P]
        ProxyPassReverse http://127.0.0.1:81/
        Order allow,deny
        Allow from all
    </Location>

</VirtualHost>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

为什么重写不正常一直打正常补丁？

来自RewriteRule Directive：

In VirtualHost context, The Pattern will initially be matched against the part of the URL after the hostname and port, and before the query string (e.g. "/app1/index.html"). This is the (%-decoded) URL-path.

If you wish to match against the hostname, port, or query string, use a RewriteCond with the %{HTTP_HOST}, %{SERVER_PORT}, or %{QUERY_STRING} variables respectively.

因此，您将需要这样的东西：

RewriteEngine On
RewriteCond %{QUERY_STRING} requestid=(.+)
RewriteRule ^/$ http://127.0.0.1:81/?requestid=%1 [P]
