hi,

I have installed nginx on linux and started it successful with default  
config file.  
but I can’t open my website. the error message in the IE is the  
connection has been interrupt.  
and there is nothing in the access log and error log.

here is information of strace:

rt\_sigtimedwait([ALRM IO RT\_11 RT\_12], {si\_signo=SIGRT\_11, si\_code=0x1,  
si\_pid=65, si\_uid=7, si\_value={int=16, ptr=0x10}}, 0, 8) = 43  
write(10, “2012/05/04 17:51:59 [debug] 1628”…, 68) = 68  
write(10, “2012/05/04 17:54:59 [debug] 1628”…, 57) = 57  
write(10, “2012/05/04 17:54:59 [debug] 1628”…, 68) = 68  
write(10, “2012/05/04 17:54:59 [debug] 1628”…, 50) = 50  
write(10, “2012/05/04 17:54:59 [debug] 1628”…, 53) = 53  
rt\_sigtimedwait([ALRM IO RT\_11 RT\_12],

please help me investigate it.

Thanks,  
Rock

Hi there,

I suggest you check non-nginx things like routers, firewalls, and other  
access control devices.

When I try to access something on that public host (currently  
210.82.101.77), the only tcp traffic I see back is a repeated syn-ack,  
followed after 5 minutes by a reset.

It looks like plain ack packets are not getting through to your  
service. It is unlikely that there is anything nginx can do about that.

If this mail makes no sense to you, ask your system- or  
network-administrator about firewalls or iptables that might be between  
your server and the internet.

Good luck with it,

Hi Francis D.,

Thanks for your time and your response.

I also ever thought the problem is about iptables and so on. but when I  
stop iptables service the problem also is there.  
and when I stop nginx and start a web server with port 80 the web  
service is working fine.

so it is very strange. Any ideas about that.

Best Regards,

Rock

rock, if you are using RedHat EL and when nginx is listening on port 80  
there is no problem, my first idea is that SELinux is denying that  
access, try with this:

grep nginx /var/log/audit/audit.log | audit2allow -m nginx \> nginx.te

and check if there are rules granting access to nginx … if that’s true,  
you can fix it with this:

grep nginx /var/log/audit/audit.log | audit2allow -M nginx  
semodule -i nginx.pp

then restart nginx and check if it is working… or you can check if it  
is trying to
