In /etc/sysctl.conf or a conf file in /etc/sysconfig.d

fs.file-max = 1000000

and run /etc/sysctl -p  /etc/sysctl.conf

in /etc/security/limits.conf

www-data       soft    nofile  500000
www-data       hard    nofile  800000

( assuming nginx is running as www-data ).

However, check your figures... setting max to a million open files, then
trying to set rlimit_nofile to 8 million is never going to work! I
suggest 800k should be plenty.
