> I can successfully use unlimit -n 65536 to set the limit higher, and then launch nginx manually from the shell and nginx is happy and doesn't complain about the 1024 limit. However when my init.d script launches nginx it still gives that warning about the limit of 1024.
You have 2 solutions:
1) execute unlimit -n 65536 in the init.d script, before starting nginx
2) if you have PAM installed, check /etc/security/limits.conf
(this is the location on Linux Debian):
www-data hard nofile 65536
