Site Files are Not Working (no replies)

marwan83 — Sun, 19 May 2013 07:10:15 -0400

Hi all,

I wish someone can help me. We have a web server that is running NginX in front of Apache. Clicking some file locations would give NginX 404 error. Below is an example:

http://store.auto-works.cc/image/flags/sa.png

http://store.auto-works.cc/admin/view/image/logo.png

Usually those files were working fine. Anyone can help me please fixing this problem?

For Http range request ie 206 , custom headers are blocked in case of x-redirect chain (no replies)

yogeshorai — Thu, 18 Apr 2013 00:44:23 -0400

I came across this strange behavior when we wanted to get Etag propagated through X-redirect chain as part of Http response for Range request ie Http 206.It seems nginx filters out any additional costume headers / tmp variable as part of final response through x-redirect for non-200 response.
Kindly suggest workaround this issue.

Here's a Log data under debug mode for Normal vs Range request clearing showing custom headers being filter out.

1.3.15 has strange new bug in http_stub_status module (no replies)

_ck_ — Tue, 02 Apr 2013 01:00:25 -0400

Cannot post to nginx trac right now, I think the trac db index is corrupted, so will post here for now.

The http_stub_status module seems broken in 1.3.15 (was fine in 1.3.14)

We were using 1.3.14 without any problems, upgraded to 1.3.15 this past weekend and now see very strange surges in our statistics before they return to normal.

Investigated the output from http-stub-status-module and the numbers are erratic.
The accepts/handled/requests counters are broken.

Here are three reading done in a row, in less than one minute.
NOTE THE SURGE IN THE MIDDLE SET which obviously are incorrect numbers.

nginx - rewrite only www to non-www (no replies)

rnk — Tue, 26 Mar 2013 03:06:26 -0400

I'm trying to redirect `www.example.com` to `example.com` This is my nginx rewrite rule:

server {
listen 80;
server_name www.upinbangalore.com;
return 301 http://upinbangalore.com$request_uri;
}

server {

listen 80;
server_name upinbangalore.com;

[...]

The redirection for **www to non-www** is working fine. But the problem is the other sub domain `mail.example.com` which I've set **CNAME records** to the mail server is also getting redirected to `example.com`

How could I avoid this?

This is my DNS setup in Linode.

A/AAAA Records
Hostname IP Address TTL Options
xxx.xxx.xxx.xxx Default Edit | Remove
www xxx.xxx.xxx.xxx Default Edit | Remove

CNAME Records
Hostname Aliases to TTL Options
mail go.domains.live.com Default Edit | Remove

Thanks!

Nginx URL rewrite changes URL (1 reply)

maxim.dsouza — Fri, 22 Mar 2013 14:56:28 -0400

I need to redirect a URL in nginx. My rule looks like this which actually causes the browser to visibly change the URL, which is not what is expected.

location / {
rewrite ^/dentists/bangalore/indiranagar/$ http://abc.com/doctorsInArea.htm?cID=bangalore&aID=indiranagar break;
}

I read another question here nginx rewrite WITHOUT change url which tells me to remove the http part . I tried

location / {
rewrite ^/dentists/bangalore/indiranagar/$ /doctorsInArea.htm?cID=bangalore&aID=indiranagar break;
}

This one throws a 404 even though http://abc.com/doctorsInArea.htm?cID=bangalore&aID=indiranagar works fine when hit from the browser. Any insights on the problem would be apprreciated.

Nginx_client has masses of files, should a cron job clean it daily? (1 reply)

Sicilian — Wed, 13 Mar 2013 21:53:44 -0400

Over a year ago we had someone install Nginx on our dedicated server that hosts quite a busy Forum.

Cut a long story short I've found the nginx_client has masses of files in the directory.

At the moment I'm trying to empty the directory via terminal: -

root@server [~]# cd /home
root@server [/home]# ls
./ .cpan/ cpeasyapache/ munin/ oeallian/
../ .cpanm/ cpins/ MySQL-install/ quota.user*
aquota.user* .cpcpan/ lost+found/ nginx_client/ worldsat/
root@server [/home]# cd nginx_client
root@server [/home/nginx_client]# rm -rf ./*

The above has been now running for four hours and still not emptied the directory.

I briefly spoke to the guy who installed Nginx (who's not being very helpful now) he tell's there was a cron job in place to clean the directory.

I remember when the guy installed nginx he had to put nginx_client directory in /home, due to it filling /tmp to fast, so I think the cronjob was never setup correctly.

Crontab has the following: -

SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/

# run-parts
01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly

I've found tmpwatch in /etc/cron.daily

flags=-umc
/usr/sbin/tmpwatch "$flags" -x /tmp/.X11-unix -x /tmp/.XIM-unix \
-x /tmp/.font-unix -x /tmp/.ICE-unix -x /tmp/.Test-unix \
-X '/tmp/hsperfdata_*' 240 /tmp
/usr/sbin/tmpwatch "$flags" 720 /var/tmp
for d in /var/{cache/man,catman}/{cat?,X11R6/cat?,local/cat?}; do
if [ -d "$d" ]; then
/usr/sbin/tmpwatch "$flags" -f 720 "$d"
fi
done

I'm no expert coder and am very lost with this. Cleary the above is not going to empty /home/nginx_client.

Please can anybody help me empty the directory nginx_client faster, at the moment its taking hours and still not empty. Also please help me with the correct cron command to clean it daily.

Thank you in advance.

websocket проксирование (no replies)

retailret — Tue, 12 Mar 2013 17:26:44 -0400

Здравствуйте. Я использую nginx 1.2.1 вместе с модулем tcp-proxy-module. Соединения проксируются на nodejs, используется socket.io . Клиент - флэш приложение, соединение через бинарный сокет. В библиотеке socket.io при отсоединении клиента срабатывает событие "disconnect". Я не сильно разбираюсь в тонкостях протоколов, но попытаюсь объяснить. Так вот, если из флэш приложения мы закрываем соединение - socket.close() - по-видимому отправляется пакет который говорит "пока" и соединение закрывается, событие disconnect сразу отрабатывает. Напомню, всё это происходит через nginx. Если у клиента пропало интернет соединение - пакета на закрытие не отправляется (возможно) и событие disconnect не наступает, а нужно, что бы это было сразу определено. Возможно ли отследить отвалившегося клиента и сделать так, что бекэнд корректно отработает закрытие. Я пытаюсь понять как это можно решить и кто (nginx или nodejs) "виноват". Как проксируются такие постоянные соединения? Влияют ли таймауты (и какие) на это всё? Как обстоит c этим дело в новом nginx? Я не тестировал функционал проксирования в новой версии nginx.

ngx_lua - ngx.var.request_body search (no replies)

achuth — Tue, 12 Feb 2013 07:53:29 -0500

Hi All

I am using nginx as a reverse proxy. The reverse proxy works based on the content of the request body. But at times the request body is too huge and hence content searching is taking too much time.

And my requirement is once I find the first occurence of the word in the body, I dont have to search for it. Rather would forward the complete request intended orginal server. So is there any progressive way of searching the content of the request body rather than storing the complete request and then searching which seems to be very time consuming. Even for a 1 KB body was taking around 20 secs.

Also am using the lua plugin for this in nginx.

Any help is much appreciated.

regards
Achuth

Nginx reverse proxy - pretending a different URL (1 reply)

notafake — Mon, 04 Feb 2013 09:20:42 -0500

Hy all

I'm a beginner in nginx reverse proxy things, so excuse the maybe dump questions.

We use a nginx as reverse proxy to access several web applications form unsecure zones.
I type in jira.example.com and it goes through firewall, reverse proxy to the web application. But for internal use we use the different URl jira.example.int (which is defined as baseurl inside the application).
Now atlassian jira takes intensive usage of the baseurl configured, the app will not work as needed if the URL is wrong / does not match the baseurl.

Question: how can I "pretend" the URl jira.example.int although I use jira.example.com?
I thought it'll require something like url rewriting but I'm really not that good in this proxy thing. And our specialist isn't around right now.

thanks in advance for any help or suggestions

client_body_buffer_size 128K;
client_max_body_size 5M;
sendfile on;
send_timeout 900s;
keepalive_timeout 300;

Then error was fixed, but now what is happening while uploading 3-4 Mb size file browser keep uploading the file and after sometime a blank page appears with below error in log files.

[ERROR] 04:58:32 ErrorHandler - Error encountered

HTTP Speed vs. HTTPS Speed (no replies)

deliarmin — Fri, 01 Feb 2013 03:29:31 -0500

Hi,

I installed a testsetup to find the impact of ssl on nginx performance (requests per second)

I don't understand a behaviour with the Testsetup I have here.

The setup:

a nearly naked Ubuntu 12.04 with:
- Apache listening on Port 8080 for HTTP Request serving the standard static welcome page.
- Nginx as a reverse proxy with 2 sites:
- default passing http to apache
- default-ssl playing ssl endpoint for the apache server

the "problem" is: i get nearly double the request per second with ssl compared to simple http. How can it be?

this is my default config:
server {
listen *:80;
location / {
proxy_pass http://localhost:8080;
}
}

this is the default-ssl config:

server {
listen *:443;
ssl on;
ssl_certificate server.crt;
ssl_certificate_key server.key;
location / {
proxy_pass http://localhost:8080;
add_header Front-End-Https on;
}
}

Can anybody explain to me why this happens, or what I am doing wrong?

Armin

edit: I'm using wrk to test:

wrk -t8 -c400 -r10m https://serverip/

external access to owncloud (no replies)

catoutnow — Wed, 30 Jan 2013 05:46:10 -0500

Hi All

I recently installed owncloud which works they way it should when I'm on my own network. However I have difficulties accessing externally:

I set up a dlinkddns account which tracks my ip however I seem to forward to the wrong port. When I use my dlinkddns address, it sends me to my router login page rather than owncloud.

How can I find out which port nginx is using for owncloud?

Any help is much appreciated :)

Optimizing Nginx for serving 1GB files - Finding values for 'directio' & 'output_buffers' (no replies)

jayaraj.k — Tue, 22 Jan 2013 10:02:05 -0500

Hi All,

We have a Nginx web server which is serving files whose size is almost 1GB. We were trying to optimize the configuration with directio & output_buffers directives. but, we couldn't find any calculation/formula with which we can identify suitable values for above mentioned directives.

Server Spec

Processor: Intel E5-2600 Xeon Family (2cpus,16 cores each)
RAM: 32GB
Nginx Version: 1.3.9 (dev)

Could you plz explain how we can find values for 'directio' & 'output_buffers' specific to a server.

Thanks

load balance traffic by nginx (no replies)

ilik1989 — Fri, 28 Dec 2012 04:23:37 -0500

Hi everybody.
I am interested in setting up site with some servers where nginx would work as a balancer but not proxying all requests, as the server where proxy is located can not handle so much network traffic sent by servers back
For example i have 3 servers with weight of each : first server -> 1 weight , second-> 2 weight, third->3 weight
When request comes nginx have to send clients to second server 2 times oftener, third server 3 times oftener than first server and these servers then establish tcp session with clients bypassing nginx proxy server which's function is only to check if the servers are available
Is it possible?

filename resolution error after regex captures & matching if (1 reply)

dweeves — Fri, 30 Nov 2012 08:47:36 -0500

First , i will apologize for the setup i use : cygwin recompilation of nginx 1.2.5 source (not very officially supported) , but i noticed this :
(using --with-debug compilation)

I think i found a bug in the filename construction from regexp (when using a matching if before)

Problematic configuration entry:

location ~ ^/test1/hls/(.*?/*)\.m3u(.)
{
alias //gagarine/poubelle/seb/hls/$1.m3u$2;
if ($hlsexp)
{
expires 0;
}
}

I'll put a "Analyzed debug log" alongside the corresponding config part i suppose it matches

Proxy: Multiple requests for uncached file (no replies)

Killiconn — Thu, 22 Nov 2012 15:36:06 -0500

I am using Nginx as a proxy to cache very large files.

When I make a request for a file that is not in the cache it goes upstream to get it, as it should.

When I make a second request for the same file, the first one still downloading, I see Nginx create another connection upstream to get the file. (all subsequent requests are the same until the file is fully cached).

I would think that there is should be a way for it to know that it already has a connection streaming in this file and be able to use what it is sending. I would think the second file would download around the same speed as a cached file until it catches up to the first request for the file.

Does Nginx already support this and I'm just not configured properly?

Thanks for any help in advance.

nginx sometimes doesn't start (2 replies)

pgm — Thu, 13 Dec 2012 13:31:47 -0500

Hello,

I wondered if you could help? We have a strange intermittent problem.

We use the Phoenix Server pattern[1] which means we throw away our servers and rebuild them from scratch rather than upgrade them. We do this at least once a day. We use Puppet to configure our boxes which run Ubuntu Precise. We run a number of nginx servers for different purposes (one for hosting monitoring dashboards, one for static content etc.), though all are very simple and similar.

Our Puppet config, for nginx, is very simple, we drop in a single nginx.conf (see below) and replace default-site.

What we've noticed is that sometimes nginx is found wanting and we are left with a server without nginx running. This happens about one in every hundred or less deploys so is very,very intermittent.

If we ssh onto the box and start nginx manually it works fine. We've found this happens on boxes with different site configurations (so sometimes the monitoring server, sometimes the static content).

The big problem we have is that there appears to be no log entries anywhere, in syslog or /var/log/nginx which suggest whether nginx started or even if it experienced any problems on startup - we've also found this with 'healthy' nginx installs, nginx doesn't seem to log any application messages anywhere.

On one occasion I was lucky enough to find a single access.log.1 which had a single 400 entry with a timestamp that matched the puppet run. This seems to suggest that nginx did indeed come up for a period of time but decided to go down. I have guessed that this is to do with the ordering of the puppet script which install nginx package, which in turn starts nginx service, puppet then drops config files and tells nginx to restart (using notify => Service[nginx]). I'm suspicious that nginx is sometimes failing to complete the restart (as in it stops but doesn't start up again) but for some reason the init.d is returning a good exit status.

So, two questions really: any ideas why nginx would not be starting? And how do we configure nginx so it gives some log output so we can attempt to diagnose nginx instances that fail to start up?

Many thanks

is it possible to use Nginx to manipulate web content without having to make changes to the web server or content (1 reply)

buzibuzi — Tue, 20 Nov 2012 08:56:30 -0500

Hi, I am doing some research on how to manipulate web content coming from my web servers without having to make any changes to the original content or web servers. what i need is a kind of a "Dynamic Content Proxy".

Can Nginx be a suitable platform for this ? to be a generic intermediate server of the flow of content from the web server to the client ?

I'm guessing as far as performance it's the best way to go since it's already optimized for this kind of flow.

Can anyone direct me on where to start and what would be the best way to work on this ? is this something that can be done by developing a Nginx module ?

Looking forward for your advise.
Thanks

High traffic site running slow (1 reply)

particle — Wed, 05 Dec 2012 02:23:43 -0500

Hi everyone,

I am running a high traffic site with some friends and recently we switched from Apache to Nginx. We're having large problems since then. When we hit like 300 visitors the site loads very slow. It can take about 10+ seconds for a page to load.

It only seems to be pages with PHP that loads slowly. We don't have the samme issue on pages with pure HTML. After searching the Nginx forums we don't seem to be the only ones with this issue, but I haven't found any solution for it when I've searched. Any help with this is really appreciated!

Nginx utilizes a ton of CPU during peak hours (no replies)

robotman321 — Tue, 30 Oct 2012 18:53:52 -0400

Hello, I'm hoping someone would be able to assist in my dillemma, ive searched for a few days on a fix with no success.. I run Nginx in proxy passthrough mode to apache.. (I hope I got the right terminology..), but basically, we've been seeing issues with our Media server, where once we start getting enough requests to make the bandwidth get above 100mbit, we start seeing drops on our cacti graphs.. when i can get online as the time, I notice that Nginx is utilizing a ton of CPU causing the server to slow down considerably.. I'm worried that my configuration has some issues and I would really appreciate the help from the community. Details on the server, brand new dell r515 (6 cores, 16GB RAM, 2 15K SAS drives for the os in a RAID 0, 12 2TB HDDs in a RAID 6 for the media). Average file size is 120MB, they don't deviate more than +/-5% of that size.. so its quite consistent..

Here is the config we use.. We have a custom built CDN that uses nginx, and we can get the same files served over 120mbit with no issues.. so im sure its something i tweaked that is wrong..

nginx_upstream_jvm_route - related (2 replies)

narayanab16 — Sun, 28 Oct 2012 12:34:07 -0400

Hi,

Link ==> http://code.google.com/p/nginx-upstream-jvm-route/

step1) /opt/httpwebserver/nginx_upstream_jvm_route $ patch p0 < jvm_route.patch
step2 /opt/httpwebserver/nginx-1.3.7$ ./configure --add-module=../nginx_upstream_jvm_route
step3)make
step4) make install

Everything is success untill now - life is easy

StepA) i have removed step1 folder i.e nginx_upstream_jvm_route and freshly extracted nginx-upstream-jvm-route-0.1.tar.gz
StepB) /opt/httpwebserver/nginx-1.3.7$ ./configure --add-module=../nginx_upstream_jvm_route
stepC) make
stepD) make install

Build failed i.e stepC & D.

../nginx_upstream_jvm_route/ngx_http_upstream_jvm_route_module.c:477: error: ‘ngx_http_upstream_srv_conf_t’ has no member named ‘lengths’

if i try to apply patch again step1) /opt/httpwebserver/nginx_upstream_jvm_route $ patch p0 < jvm_route.patch

i get this error

FLV Module (no replies)

isbrasil — Sat, 22 Sep 2012 15:25:59 -0400

I installed the module and flv to mp4

mp4 worked perfectly without any problems

FLV he accuses no error, but does not work, start the video according to the defined start.

I saw in some forums that needed within the flv inform the path again, and it also did not work anyway.

location ~ \.flv$ {
flv;
root /home/isb/public_html;
}
location ~ \.mp4$ {
mp4;
}

nginx -V
nginx version: nginx/1.2.3
built by gcc 4.4.6 20120305 (Red Hat 4.4.6-4) (GCC)
TLS SNI support enabled
configure arguments: --with-pcre=/usr/local/src/publicnginx/pcre-8.30 --sbin-path=/usr/local/sbin --conf-path=/etc/nginx/nginx.conf --pid-path=/var/run/nginx.pid --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --with-http_realip_module --with-http_ssl_module --http-client-body-temp-path=/tmp/nginx_client --http-proxy-temp-path=/tmp/nginx_proxy --http-fastcgi-temp-path=/tmp/nginx_fastcgi --with-http_stub_status_module --with-http_flv_module --with-http_mp4_module

my test

test.flv?start=150

it downloads the video from the beginning without respecting the start informed.

--

test.mp4?start=150

works perfectly and starts from where it was set.

the problem only occurs in FLV

Can someone give me a hand? Thank you.
