关于apache2的443端口进行转发遇到的问题

Question

1.问题，我目前有多个docker容器，那么假如都需要用80端口访问，当80:80进行映射，导致这个80端口被占用，因此在宿主机，我装了一个apache2进行端口转发。

过程如下:外网对于80端口，我通过宿主机的apache2转发至8880端口，然后通过dokcer的端口映射8880:80访问容易内部的服务，至此，并未出现问题。但是当外网访问443端口，即https访问，页面报错400,检查了很久也没找到原因，求助。

宿主机的配置如下:

<VirtualHost *:80>
    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.

外网访问80端口，转发到本地的8880然后再映射给docker，便可以访问。但是这个443端口，映射确报400错误，求助！！

Answer 1

    ProxyPass / http://127.0.0.1:8883/ timeout=600 Keepalive=On
    ProxyPassReverse / http://127.0.0.1:8883/ timeout=600

估计问题出现在这， 如果你的docker 8883端口下采用https协议，那也要相应地改成

    ProxyPass / https://127.0.0.1:8883/ timeout=600 Keepalive=On
    ProxyPassReverse / https://127.0.0.1:8883/ timeout=600
