HAProxy
HAProxy 是一个广为人知的高性能反向代理。 现代的 HAProxy(2.x 及更新版本)只要设置较长的 timeout tunnel 就能透明地转发 Owncast 的 WebSocket 聊天,因此不需要单独的 WebSocket 后端。
下面的 haproxy.cfg 在端口 80 和 443 上终止 TLS,并将流量转发到 Owncast 的 8080 端口。 它期望你的证书链和私钥被合并为位于 /etc/haproxy/certs/owncast.pem 的单个 PEM 文件。 使用 Let's Encrypt,你可以用 cat fullchain.pem privkey.pem > /etc/haproxy/certs/owncast.pem 来生成该文件。 更改证书路径和 127.0.0.1:8080 后端地址以匹配你的设置。
