Andrey Zentavr's questions

I have apache as a backend and nginx as a frontend. Some content is password-protected by Apache (HTTP Auth).

When I access it directly - everything works fine, bur when I try it through nginx - seems like nginx doesn't forward or cache the responses from Apache. So inside nginx log I see:

89.21.92.0 - - [17/May/2012:22:13:42 +0200]  GET / HTTP/1.1 | upstream_address x.x.x.x:80 | upstream_status 401 | upstream_response_time 0.026 | msec 1337285622.757 | request_time 0.026
89.21.92.0 - zentavr [17/May/2012:22:13:44 +0200]  GET / HTTP/1.1 | upstream_address - | upstream_status - | upstream_response_time - | msec 1337285624.151 | request_time 0.000

On Apache's side:

y.y.y.y - - [17/May/2012:22:13:42 +0200] "GET / HTTP/1.0" 401 652 "-" "Mozilla/5.0 (Windows NT 6.1; rv:12.0) Gecko/20100101 Firefox/12.0" "89.21.92.0"

What could be the issue?

I try to increase open file limit for certain user on CentOS 5.5 Linux. I added a new line to /etc/security/limits.conf:

seed     hard    nofile          10240

Then do test:

runuser -s /bin/bash - seed -c "ulimit -S -c 0>/dev/null 2>&1; ulimit -a"
0
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 8185
max locked memory       (kbytes, -l) 32
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 10240
cpu time               (seconds, -t) unlimited
max user processes              (-u) unlimited
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

And as you can see - open file limit is still 1024. If I set up the limit as 1000, it will be applied. So, I cannot setup the limit more than 1024.

How can I do that?? I need to set up the settings only for 1 user, not system-wide.
