For Http range request ie 206 , custom headers are blocked in case of x-redirect chain

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

_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

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!

Re: Nginx URL rewrite changes URL

voodooKobra — Fri, 22 Mar 2013 14:56:28 -0400

rewrite ^/dentists/([a-z]+)/([a-z]+)/?$ /doctorsInArea.htm?cID=$1&aID=$2;

Does this work? You don't want to use http:// for rewrite

Nginx URL rewrite changes URL

maxim.dsouza — Thu, 21 Mar 2013 07:20:44 -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.

Re: Nginx_client has masses of files, should a cron job clean it daily?

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

I've done some more investigation and now not even sure if the guy who originally installed Nginx removed it at a later date. If I do 'top' command I see no nginx process running at all.

Going by this site http://library.linode.com/web-servers/nginx/configuration/basic there should be nginx configuration in /opt/, but there is not.

How can I check if the nginx_directory was just been left over?
How can I check if nginx is still installed or not?

Nginx_client has masses of files, should a cron job clean it daily?

Sicilian — Wed, 13 Mar 2013 21:45:22 -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

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

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

You solve this with an internal DNS system, which is very simple to do, talk to your network administrators.

Nginx reverse proxy - pretending a different URL

notafake — Mon, 04 Feb 2013 08:19:26 -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

Trow this "org.apache.commons.fileupload SizeLimitExceededException" into google, plenty of solutions.

Thanks for the reply...
Is there any settings in tomcat for enabling File upload or file limit.

As i tested the same on my windows machine with same setup and no blank page is displaying.....It just show the above mentioned error on the browser where as in Linux [CentOS 6.2 x64] it shows blanks page and the error is displaying in log file.

This looks like a tomcat error and not a nginx issue.

Hello,

We have a application is jsp which is running on tomcat and using nginx as a front. Now what was happening while uploading the file using application the error thrown by nginx on web browser was "413 Request Entity Too Large". So what i did i add below lines in virtual host file.

client_body_in_file_only clean;
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

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

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'

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
Jayaraj

load balance traffic by nginx

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?

index.php work. index.php&login=true dont work

t3ch — Thu, 27 Dec 2012 08:23:32 -0500

Hello all,

I have problem with accessing index.php&login=true. It gives 404 error. But when i try to access only index.php it works.

here is config: sites-available/localhost.conf

server {
listen 80;
server_name localhost;
access_log /var/log/nginx/localhost.access.log;
error_log /var/log/nginx/localhost.error.log;

root /home/user/www/localhost/htdocs;
#autoindex on;

location /pma {
index index.php;
}

location / {
index index.php;
}

location ~ \.php$ {
# Filter out arbitrary code execution
#location ~ \..*/.*\.php$ {return 404;}

include fastcgi_params;
fastcgi_pass localhost:9000;
#fastcgi_pass unix:/var/run/php5-fpm.socket;
#fastcgi_pass localhost;
}
}

Make sure you stop the apache2 service and remove apache2 during the automated fresh install phase.

Re: nginx sometimes doesn't start

pgm — Mon, 10 Dec 2012 08:39:59 -0500

I have discovered that nginx returns a status code 0 when the init.d script fails to start.

If I force an error I see output in /var/log/nginx/error.log so I'm not sure why we're not getting any output there. Any clues?

Below I have the output of a fresh, default installation of nginx but something is already running on port 80 causing the startup to fail. However, as you can see the status code is 0.

Nope. I upgraded from 1.1.19 back then to 1.2.4 and now 1.3.9 and I am still facing the problem.
My system is running under Ubuntu 3.5.0-19 and apparmor is running. Keep me posted if you find something.
