Did you correctly set id,pw for mysql and setup database for rAthena yet?
Try follow this guide maybe it's help if you miss some step: https://github.com/rathena/rathena/wiki/Install-on-Centos
Not sure but you can try
\src\map\script.cpp >> lines 11187. (Copy/Look at this line of code)
Then go to channel src files.
Try to check it's trade channel and announce it.
Are you using git programs to download rAthena? If yes just press fetch & pull then see the conflict and solve them.
If not you need to manualy update it.
