关于socket.io 负载均衡问题，参考官网Using multiple nodes:http://socket.io/docs/using-multiple-nodes/, 我设置如下：
var io = require('socket.io').listen(8891); var port=6379; var host='localhost'; var pwd = '******'; var redis = require('redis').createClient; var adapter = require('socket.io-redis'); var pub = redis(port, host, { auth_pass: pwd }); var sub = redis(port, host, { detect_buffers: true, auth_pass: pwd }); io.adapter(adapter({ pubClient: pub, subClient: sub })); 关于这个adapter 总是报错：
io.adapter(adapter({ pubClient: pub, subClient: sub })); ^ TypeError: undefined is not a function at Object.<anonymous> (/home/team/project/ylx/sync-svc/sync-server_8891.js:18:4) at Module._compile (module.js:462:26) at Object.Module._extensions..js (module.js:480:10) at Module.load (module.js:357:32) at Function.Module._load (module.js:312:12) at Function.Module.runMain (module.js:503:10) at startup (node.js:132:16) at node.js:817:3 我的socket.io版本0.9.17，其他版本见下方：
