Nginx load balancer websocket issue -


i'm new in nginx , websocket systems per project requirements need check complex things finish.

i'm trying create 1 example using nginx, handles websocket (port: 1234) , http requests (port: 80) using same url (load balancer url).

i'm using 3 nginx server, 1 load balancer (10.0.0.163) , other 2 application server have installed real apis, 10.0.0.152 , 10.0.0.154 respectively. right now, have configured websocket on application servers.

as per above configuration, requests pass on 10.0.0.163 (load balancer) , it's proxy setting pass request (http/websocket) application server (10.0.0.152/154).

note : each application server contain separate nginx, php, websocket

here default (location : /etc/nginx/sites-available/) file 10.0.0.154 server, handles websocket , http requests on same domain.

server{     listen 80;         charset utf-8;         root /var/www;         index index.html index.htm index.php         server_name localhost 10.0.0.154 ;     location ~ \.php$ {         fastcgi_split_path_info ^(.+\.php)(/.+)$;         fastcgi_pass 127.0.0.1:9000;         fastcgi_index index.php;         include fastcgi_params;     }     location / {             try_files $uri $uri/ @proxy;    autoindex on;     }     location @proxy{         proxy_pass http://wb1;     }     location =/ {                 proxy_pass http://wb;                        proxy_http_version 1.1;                 proxy_buffers 8 16k;                 proxy_buffer_size 32k;                 proxy_set_header upgrade $http_upgrade;                  proxy_set_header connection "upgrade";                 proxy_set_header host $host;                 proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;         proxy_set_header        referer                 $http_referer;         proxy_redirect off;          }  }

following default file (location : /etc/nginx/sites-available/) load balancer @ 10.0.0.163.

upstream wb{     server 10.0.0.154;     server 10.0.0.152; }  server{     listen 80;         charset utf-8;         root /var/www;         index index.html index.htm index.php         server_name 10.0.0.163 ;      location / {             try_files $uri $uri/ @proxy;    autoindex on;     }     location @proxy{         proxy_pass http://wb;     }     location =/ {                 proxy_pass http://wb;                        proxy_http_version 1.1;                 proxy_buffers 8 16k;                 proxy_buffer_size 32k;                 proxy_set_header upgrade $http_upgrade;                  proxy_set_header connection "upgrade";                 proxy_set_header host $host;                 proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;         proxy_set_header        referer                 $http_referer;         proxy_redirect off;          }  }

i found that, load balancer working http requests it's unable proceed websocket requests application server.

i don't know i'm missing here .. if guys can me out great appriciate

i seen configuration looks proper. think should check load balancer & application server configuration or versions. maybe problem of incompatibility.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
