apache ProxyPass 是否也处理 websocket 的 tls？

  • 772

我是 proxypass 的新手，假设这是我们的配置：

<IfModule mod_ssl.c>
<VirtualHost *:443>
        # 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.
        #ServerName www.example.com

        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf


ServerName www.xzos.net
Include /etc/letsencrypt/options-ssl-apache.conf
ServerAlias xzos.net
SSLCertificateFile /etc/letsencrypt/live/www.xzos.net/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/www.xzos.net/privkey.pem

<LocationMatch "/ray/">
        ProxyPass ws://127.0.0.1:1080/ray/ upgrade=WebSocket
        ProxyAddHeaders Off
        ProxyPreserveHost On
        RequestHeader set Host %{HTTP_HOST}s
        RequestHeader set X-Forwarded-For %{REMOTE_ADDR}s
</LocationMatch>
</VirtualHost>
</IfModule

由于我们将这些提供给 apache

SSLCertificateFile /etc/letsencrypt/live/www.xzos.net/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/www.xzos.net/privkey.pem

我们不应该也需要在运行的 websocket 服务器中使用它们，对ws://127.0.0.1:1080/ray/吗？

即使我们可以做到，但 Apache 处理得对吗？我想，因为这是本地服务器，所以专门做两次是多余的。我认为如果我们这样做，那么ws://127.0.0.1:1080/ray/需要成为wss://127.0.0.1:1080/ray/我们提供相同证书密钥的 websocket 服务器内部。

    使用 proxyPass 代理到本地主机上不安全的侦听器仍然可以暴露攻击面。您是否担心有人在本地主机上嗅探流量？如果我是一个具有适当访问权限的不法分子，我可以在端口 1080 上的环回接口上进行 tcpdump 并读取流量。如果你使用 wss:// 那么这样做会更加困难。我会在两个链接上都使用 TLS，除非有技术原因不这样做，或者如果我正在调试应用程序并需要在该过程中获取更多信息。
