v117.2 start error

hey, i recently switch for windows vps to a linux centos6.0 cloudvps.

I installed :
java jre and jdk
added policy files to security
mysql
exucted the sql
putted the ip in len file
opened all the ports

But when i launch it it gives me the error :
were unable to connect to login server blah blah....

Any idea ? did i miss something ?

Edited the settings for the IP of the server?

Changed ip in worldgms.properties and in serverconstants.java but still not working. (And channel.properties)
