</div>All of them set RLIMIT_NOFILE (man 2 setrlimit).<br>
If there is worker_rlimit_nofile directive in nginx.conf, nginx master process<br>
sets RLIMIT_NOFILE for new workers processes. This works no matter how<br>
you start nginx.<br>
ulimit -n in init script will works if nginx is started by init script.<br>
limits.conf is used by pam_limits, so it works for:<br>
% grep pam_limits /etc/pam.d/*<br>
/etc/pam.d/atd:session required pam_limits.so<br>
/etc/pam.d/cron:session required pam_limits.so<br>
/etc/pam.d/login:session required pam_limits.so<br>
/etc/pam.d/sshd:session required pam_limits.so<br>
/etc/pam.d/su:# session required pam_limits.so<br>
<br>
atd, cron, login, sshd processes and their child processes,<br>
for example when you login locally or via ssh.<br>

</div>limits.conf will not work if init script is started on system boot.<br>
