nginx反向代理websocket wss或ws端口

1.直接上nginx配置文件

注意：

后端端口使用wss：proxy_pass https://wss_8;
后端端口使用ws ：proxy_pass http://wss_8;

upstream wss_8{
    server 127.0.0.1:8004;
}
 
###

server {
    listen       8104 ssl;
    server_name  bbxx.ios.xxx.com;

    #ssl on;
    ssl_certificate ssl/xxx.com.crt;
    ssl_certificate_key  ssl/xxx.com.key;
    ssl_protocols  TLSv1 TLSv1.1 TLSv1.2 SSLv2 SSLv3;
    ssl_ciphers  ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;

    access_log  /var/log/nginx/wss_8_forward_port_8104.access.log;
    error_log  /var/log/nginx/wss_8_forward_port_8104.error.log;

    location / {
        add_header Access-Control-Allow-Origin *;
        proxy_redirect off;
        proxy_pass https://wss_8;
        proxy_set_header Host $host;
        proxy_set_header X-Real_IP $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr:$remote_port;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;  
        proxy_set_header Connection "Upgrade";  
    }
    error_page   500 502 503 504  /50x.html;
}
