我正在尝试配置Digital Ocean本机负载平衡器以分配WebSocket流量。我设置了规则:{{3}}
在尝试通过负载均衡器进行连接时,我得到:
VM915:1 WebSocket connection to 'ws://{loadbalancerip}:8443/' failed: Connection closed before receiving a handshake response
。
直接连接就可以了。
那我该如何配置负载均衡器来平衡websocket的流量呢?
答案 0 :(得分:0)
由于Digital Ocean Load Balancer似乎不支持开箱即用,我不得不购买一个小型实例并在其上进行配置 Nginx 以平衡3台本地计算机之间的传入流量
这里是 Nginx 的可能配置,它使您能够平衡wss
从Cloudflare转发到8443端口的流量:
upstream wss {
# Clients with the same IP are redirected to the same backend
# ip_hash;
# Available backend servers
server 228.228.228.1:8443 max_fails=3 fail_timeout=30s;
server 228.228.228.2:8443 max_fails=3 fail_timeout=30s;
server 228.228.228.3:8443 max_fails=3 fail_timeout=30s;
}
server {
listen 8443 ssl default_server;
listen 443 ssl default_server;
listen [::]:8443 ssl default_server;
include snippets/self-signed.conf;
include snippets/ssl-params.conf;
underscores_in_headers on;
root /var/www/html;
index index.html index.htm index.nginx-debian.html;
server_name _;
location / {
# switch off logging
access_log off;
try_files $uri $uri/ =404;
# redirect all HTTP traffic to wss
proxy_pass https://wss;

proxy_pass_request_headers on;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header HTTP_CF_IPCOUNTRY $http_cf_ipcountry;
# WebSocket support (nginx 1.4)
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
# Path rewriting
rewrite /wss/(.*) /$1 break;
proxy_redirect off;
}
}
