background - Why, dows 'neo4j console' work, and 'neo4j start' doesn't? -

i want use neo4j. installed neo4j-community 2.3.2-1 archlinux aur , when ise neo4j consoleeverything works fine. when want start server in background neo4j startthe server won't start error message:

warning: max 1024 open files allowed, minimum of 40 000 recommended. see neo4j manual. starting neo4j server...process [20559]... waiting server ready... failed start within 120 seconds. neo4j server may have failed start, please check logs. 

the server did not try start or 120 seconds, more 2 seconds. in addition callot find log-files anywhere. google told me tryout neo4j start-no-wait when command:

warning: max 1024 open files allowed, minimum of 40 000 recommended. see neo4j manual. starting neo4j server...process [21088]...started server in background, returning... 

but nothing started , webclient doesn't work when use neo4j console.

so basic question is: why neo4j consolework , neo4j startdoes not? , how can start neo4j in background , stop again without killing process?

edit: console.log says:
