node.js - socket.io redis store on openshift -

i'm trying set socket.io on node.js use redisstore can comunicate pubsub multiple node on opeshift platform, can't manage connect redis server. i'm using this cartridge. tried connect with

var pub    = redis.createclient(process.env.openshift_redis_db_port,                                 process.env.openshift_redis_db_host); 

but doesn't work (and found out why: createclient() accept ip addresses) , fallback default port , host, ran rhc port-forward:

$ rhc port-forward appname checking available ports ... done forwarding ports ... address in use - bind(2) while forwarding port 8080. trying local port 8081  connect service running on openshift, use local address  service         local                openshift --------------- --------------- ---- ---------------------------------------------- haproxy         127.0.0.1:8080   =>  127.5.149.130:8080 haproxy         127.0.0.1:8081   =>  127.5.149.131:8080 s_redis_db_host 127.0.0.1:54151  =>  blabla.appname.rhcloud.com:54151  press ctrl-c terminate port forwarding 

so tought doing wrong , had set port this:

var pub = redis.createclient(process.env.openshift_redis_db_port); 

but this

info: socket.io started events.js:72      throw er; // unhandled 'error' event            ^ error: redis connection 127.0.0.1:54151 failed - connect econnrefused  @ redisclient.on_error (/var/lib/openshift/532c3790e0b8cd9bb000006b/app-root/runtime/repo/node_modules/socket.io/node_modules/redis/index.js:149:24)  @ socket.<anonymous> (/var/lib/openshift/532c3790e0b8cd9bb000006b/app-root/runtime/repo/node_modules/socket.io/node_modules/redis/index.js:83:14)  @ socket.eventemitter.emit (events.js:95:17)  @ net.js:426:14  @ process._tickcallback (node.js:415:13)  debug: program node server.js exited code 8 

i tried connect via

telnet $openshift_redis_db_host $openshift_redis_db_port 

and works fine... have suggestions? doing wrong? (i'm still new redis , socket.io) (i omitted rest of code 'cause know works, have no problem on local machine, can't connection...) lot

but doesn't work (and found out why: createclient() accept ip addresses) , fallback default port , host

it support host, createclient uses net.createconnection(port, host); support hostname.

the following code find issue:

console.log(process.env); var pub    = redis.createclient(process.env.openshift_redis_db_port,                                 process.env.openshift_redis_db_host, {auth_pass: process.env.openshift_redis_db_password}); pub.on('error', console.log.bind(console)); pub.on('ready', console.log.bind(console, 'redis ready')); 

does openshift redis instance requires auth ?
