将 nginx conf 转换为 proxypass 的 apache conf

Question

我需要将此 nginx conf 转换为 apache conf。正如我试图转换，但未能得到它。

upstream apiUpstream {

  # 1. Set your port here
  server 127.0.0.1:8080;
  keepalive 64;
}

server {
  listen 80;
  listen 443 ssl;

  # 2. Set your API domain name here
  server_name yourdomain.com;

  location / {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; # RequestHeader set X-Forwarded-Port "443"
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $http_host;

    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_pass http://apiUpstream/;  
    proxy_redirect off;
    proxy_read_timeout 240s;
  }

  # 3. SSL certificate set below
  # Here is added a sample certificate format of letsencrypt
  # You are free to remove it and configure yours here
  ssl_certificate /etc/letsencrypt/live/yourdomain.com/fullchain.pem;
  ssl_certificate_key /etc/letsencrypt/live/yourdomain.com/privkey.pem;
  include /etc/letsencrypt/options-ssl-nginx.conf;
  ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
}

到 apache conf。

  ProxyRequests On
  ProxyPass   http://apiUpstream/ timeout=240
  ProxyPassReverse http://apiUpstream.com

但它不起作用，请帮我使它可行。而且我不明白什么是顶级上游 conf 以及如何将其转换为 apache。

编辑：

我收到了这个错误

peerjs.min.js:52 WebSocket connection to 'wss://api.example.com/peer/peerjs?key=peerjs&id=6yqD1MoKzkK&token=kp8g8w6pj2l' failed: Error during WebSocket handshake: 'Connection' header is missing

我已经尝试像这样更改域的 cpanel conf。

<Proxy balancer://apiUpstream/>

 BalancerMember http:// 127.0.0.1:8080;
 keepalive 64;
 ProxySet lbmethod=byrequests
</Proxy>

ProxyRequests On
ProxyPass / balancer://apiUpstream/
ProxyPassReverse / balancer://apiUpstream/

保存后，我无法从 WHM 重新启动 apache。它的说法就像无法加载平衡器成员一样。我不知道如何解决它。

首先你需要加载模块的apache：

• mod_proxy
• mod_proxy_http
• mod_proxy_wstunnel（在 httpd 2.4.5 及更高版本中可用）docs

在 ubuntu 中，您可以通过以下方式启用此功能：

a2enmod proxy
a2enmod proxy_http
a2enmod proxy_wstunnel

您正在尝试连接到您需要连接到节点应用程序的 websocket 的 WebSocket。

试试这样的：

<VirtualHost *:443>
  ServerName example.com
      
  ProxyPreserveHost On
  RewriteEngine On
     
  # If header Upgrade: websocket found, proxy to ws
  RewriteCond %{HTTP:Upgrade} =websocket [NC]  
  RewriteRule /(.*)           ws://localhost:8080/$1 [P,L]  
  
  # If header not found use http
  RewriteCond %{HTTP:Upgrade} !=websocket [NC]
  RewriteRule /(.*)           http://localhost:8080/$1 [P,L]

  
  # SSL config
  ...
  
</VirtualHost>
