if you meet a problem like '[ERR] Sorry, can't connect to node ...', 
when you try to create a redis cluster , 
maybe the reason is that the script http://download.redis.io/redis-stable/src/redis-trib.rb don't support the auth , 
you could try this script with parameter [--password] .
    
# redis-trib.rb---password

Adding support parameters  [ --password | host:port:password ] in the script redis-trib.rb
for example：
$ redis-trib.rb check --password foobared 127.0.0.1:6380

脚本redis-trib.rb中新增支持参数--password 或 host:port:password，建议使用参数--password
例子：
$ redis-trib.rb check --password foobared 127.0.0.1:6380
