javascript - Can't access to socket.io.js on Raspberry Pi with Lighttpd [Node.JS & Socket.IO] -


i'm new node.js , socket.io since yesterday.

i try make node.js , socket.io work on raspberry pi doesn't seem to. i can't access <myip>:1337/socket.io/socket.io.js. have followed this tutorial lighttpd.conf file seems so:

$http["host"] == "<myurltomywebsite>" {     proxy.server = (" " => ((         "host" => "<myip>",         "port" => 1337)     ) )

my server.js so:

var http = require('http');  httpserver = http.createserver(function(req, res) {     res.end('hello world!'); });  httpserver.listen(1337);  var io = require('socket.io').listen(httpserver); var clients = 0;  io.sockets.on('connection', function(socket) {     ++clients;      socket.on('disconnect', function(data) {         --clients;         io.sockets.emit('disusr', clients);     });      io.sockets.emit('newusr', clients); });

and bind disusr , newusr events in client.js display number of connected users in div.

everything looks fine on localhost but, in production environment, cannot link socket.io.js file on 1337 port. honest, i'm not sure address use? (url of website appended :1337, localhost, other address have created?)

any appreciated. thanks!

i resolved problem!

i linked socket.io.js : <script type="text/javascript" src="/socket.io/socket.io.js"></script>

i used haproxy instead of lighttpd mod_proxy specified in this question

here conf file (amend <...> per configuration):

# config needs haproxy-1.1.28 or haproxy-1.2.1  global   log  127.0.0.1  local0   log  127.0.0.1  local1 notice   maxconn  4096   uid  99   gid  99   daemon  defaults   log   global   mode  http   option  httplog   option  dontlognull   retries  3   option http-use-proxy-header   option  redispatch   option  http-server-close   maxconn  2000   contimeout  5000   clitimeout  50000   srvtimeout  50000  frontend public   bind *:80   acl is_example hdr_end(host) -i <url.toyourwebsite.com>   acl is_websocket hdr(upgrade) -i websocket   acl is_websocket path_beg -i /websockets   use_backend ws if is_websocket is_example   default_backend www  backend ws     balance roundrobin     option forwardfor # sets x-forwarded-for     timeout queue 5000     timeout server 86400000     timeout connect 86400000     server apiserver localhost:<port> weight 1 maxconn 1024 check

and made lighttpd listened 8080 port (otherwise haproxy wouldn't start).

remind there no need use mod_proxy known not compatible websockets. use haproxy instead.
