Performance trouble after migration Squeeze to Wheezy (no replies)

B.R. — Fri, 24 May 2013 17:18:00 -0400

Hello,

First of all I need to emphasize the fact that I know WHeezy is not yet
supported.
What I am trying to determine how WHeezy could impact Nginx (compiled for
Squeeze) performance.

Since I made the upgrade, big files are being served in a slow fashion
(~200 kiB/s).
The directory serving them is configured with AIO and worked perfectly
before system changes.

I know Sergey listed some changes in the
dependencieshttp://mailman.nginx.org/mailman/listinfo/nginx,
but what precisely would explain such a slow-down?
Is there a defect somewhere that I can work on or just be patient and wait
for the release of the Wheezy build of Nginx?

Thanks,
---
*B. R.*

Rewriting and proxy problem (1 reply)

Sergio Belkin — Fri, 24 May 2013 15:08:01 -0400

H folks!

I am completeley newbie to nginx

I have the following config

# Forward request to /demo to tomcat. This is for
# the BigBlueButton api demos.
location /demo {
rewrite ^ /upvc;
proxy_pass http://127.0.0.1:8080;
proxy_redirect default;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

# Allow 30M uploaded presentation document.
client_max_body_size 30m;
client_body_buffer_size 128k;

proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;

proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;

include fastcgi_params;
}

location /upvc {
alias /var/lib/tomcat6/webapps/demo;
index demo3.jsp;
expires 1m;
}

Rewrite is working but nginx is not. proxying to tomcat, because of that
returns the jsp file as a plain text file.

Please could you help me?

Thanks in advance!

прошу помочь с rewrite (1 reply)

Nikolay Grebnev — Fri, 24 May 2013 13:06:01 -0400

Добрый день.

Прошу помочь с конфигурированием, не получается самому написать.
Была программа на php, например login.php . Теперь ее переписали и она
должна работать с другого апстрима и там иметь адрес /account/login. Но
убрать ссылки на login.php не представляется возможным, и на него идут как
GET так и POST запросы. Поэтому идеальное решение было бы такое (только вот
не понимаю как написать)

location /login.php {
proxy_pass http://newupstream;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header Via $http_via;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
rewrite_log on;

rewrite login.php => /account/login (пишу смысл, так не получается
написать правильно :( . Ну или работает GET вариант, а POST не получается
никак)
}

Заранее спасибо.

romanvin — Fri, 24 May 2013 10:26:13 -0400

Есть ли вариант, используя модуль ngx_http_addition_module, указывать в значении URI веб адрес (URL, например http/site.ru/pluscode.html) либо задавать путь к добавочному файлу который лежал бы в универсальном хранилище, например в /root/nginx/pluscode.html

Сейчас как я понимаю, он может лежать только в директории сайта вида
/home/user/public_html/pluscode.html
и ни в каком другом месте.

варианты вида
add_before_body http://site.ru/pluscode.html
add_before_body /home/nginx/pluscode.html

не срабатывают.

Insert Ad's in free internet traffic. (no replies)

hdavy2002 — Fri, 24 May 2013 09:49:22 -0400

Hi folks,

I don't mean to sound evil. I am trying to give free internet to my users and want to insert ad's in the internet traffic. Hoping the revenue will help support free internet. I want to use Nginx as a Cache Proxy instead of Squid. I came across mod_layout in Apache, which I understand, inserts ad's in Header and Footer dynamically. I like Nginx as it feels faster than Apache.

Would appreciate any advice.

Cheers

Socket leak (3 replies)

faskiri.devel — Fri, 24 May 2013 12:52:01 -0400

Hi all

I have been seeing slow but steady socket leak in nginx ever since I
upgraded from 1.0.5 to 1.2.6. I have my custom module in nginx which I was
sure what was the leak. This is how I went about investigating:
1. Configure nginx with one worker
2. strace on the worker process, tracing
read/readv/write/writev/close/shutdown calls
3. Every now and then, for all the open fds (from ls -l /proc//fd),
check the socket that is not available in netstat -pane
4. What I saw was, the leaking socket always had the last operation as
writev which returned an error.
5. Increased the nginx log level to info and verified that nginx was
getting ECONNRESET or EPIPE on writev failure. Which was OK.
6. Traced back in code to see how it is handled, the error translates to
CHAIN_ERROR and eventually causes ngx_http_finalize_request to be called.
This in turn calls ngx_http_terminate_request.

However, in this function, the request is not terminated if
r->write_event_handler is set. This seems to be set if the request handler
is a user module. I think the rationale for the check is, if there is a
module who is handling the request, dont terminate yet, wait for a write
event on the socket and then terminate it (which is why I thought it is
setting r->write_event_handler to ngx_http_terminate_handler).

I tried to repro this w/ empty_gif_handler however, it sends header and
body in one call to writev which I cant get to fail in my test environment.
To reproduce the bug, if I replace the call to ngx_http_send_response with
ngx_http_send_header and ngx_http_output_filter (as used by ngx_upstream or
other modules which dont have the headers and body together), I could
reproduce the leak. I have a client that sends a request and closes the
socket immediately, nginx sees the error, prints the info log, and then it
doesnt close the socket.

I have a small patch attached, the fix I did is basically saying that if
there is a connection error, there is no point setting write_event_handler
as there wont be any activity on the socket, so just terminate it
immediately.

I could be very wrong in the understanding of the code flow. My patch just
fixes this and I am not very sure if this is the right fix. Please let me
know.

I will try to add a testcase to reproduce this in the nginx test framework.

Thank you for your patience.

Regards
+Fasih

Removing port from fastcgi redirects (no replies)

zibralis — Fri, 24 May 2013 07:34:02 -0400

I'm having an issue where some redirects on a website have the proxy-pass port included, rendering them useless. My configuration is as follows:

Physical server 1:

server {
server_name example.com www.example.com;

location / {
proxy_pass http://1.1.1.1:50493;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host "example.com";
}
}

Physical Server 2:

server {
listen 50493;
server_name example.com www.example.com;

set_real_ip_from 1.1.1.1;

root /var/www/example.com;
index index.php index.htm index.html;

location / {
if ($http_host !~ "^example.com"){
set $rule_0 1$rule_0;
}
if ($rule_0 = "1"){
rewrite ^/(.*) http://example.com/$1 permanent;
}
rewrite /[^/]+/([0-9]+)-[^/]+.html http://example.com/showthread.php?t=$1 permanent;
}

location ~ .php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /var/www/example.com$fastcgi_script_name;
include fastcgi_params;
fastcgi_read_timeout 600s;
fastcgi_buffer_size 512k;
fastcgi_buffers 16 512k;
}
}

Generally, browsing works fine. The site is browsable as one expects. However some links that redirect (eg. after a login action), redirect to a link with the port 50493 included. So we get http://example.com:50493/index.php for example. That will not work. My question is, how do I remove the port in such cases?

[ANN] ngx_openresty devel version 1.2.8.5 released (no replies)

agentzh — Thu, 23 May 2013 21:22:01 -0400

Hello guys!

I am happy to announce that the new development version of
ngx_openresty, 1.2.8.5, is now released:

http://openresty.org/#Download

Special thanks go to all our contributors and users for helping make
this release happen!

Below is the complete change log for this release, as compared to the
last (devel) release, 1.2.8.3:

* upgraded LuaNginxModule to 0.8.2.

* feature: added "ngx.HTTP_MKCOL", "ngx.HTTP_COPY",
"ngx.HTTP_MOVE", and other WebDAV request method constants;
also added corresponding support to ngx.req.set_method and
ngx.location.capture. thanks Adallom Roy for the patch.

* feature: allow injecting new user Lua APIs (and overriding
existing Lua APIs) in the "ngx" table.

* bugfix: ngx.req.set_body_file() always enabled Direct I/O
which caused the alert message "fcntl(O_DIRECT) ... Invalid
argument" in error logs on file systems lacking the Direct
I/O support. thanks Matthieu Tourne for reporting this
issue.

* bugfix: buffer corruption might happen in
ngx.req.set_body_file() when Nginx upstream modules were
used later because ngx.req.set_body_file() incorrectly set
"r->request_body->buf" to the in-file buffer which could get
reused by "ngx_http_upstream" for its own purposes.

* bugfix: no longer automatically turn underscores (_) to
dashes (-) in header names for ngx.req.set_header and
ngx.req.clear_header. thanks aviramc for the report.

* bugfix: segmentation fault might happen in nginx 1.4.x when
calling ngx.req.set_header on the "Cookie" request headers
because recent versions of Nginx no longer always initialize
"r->headers_in.cookies". thanks Rob W for reporting this
issue.

* bugfix: fixed the C compiler warning "argument 'nret' might
be clobbered by 'longjmp' or 'vfork'" when compiling with
Ubuntu 13.04's gcc 4.7.3. thanks jacky and Rajeev's reports.

* bugfix: temporary memory leaks might happen when using
ngx.escape_uri, ngx.unescape_uri, ngx.quote_sql_str,
ngx.decode_base64, and ngx.encode_base64 in tight Lua loops
because we allocated memory in nginx's request memory pool
for these methods.

* optimize: ngx.escape_uri now runs faster when the input
string contains no special bytes to be escaped.

* testing: added custom test scaffold t::TestNginxLua which
subclasses Test::Nginx::Socket. it supports the environment
"TEST_NGINX_INIT_BY_LUA" which can be used to add more
custom Lua code to the value of the init_by_lua directive in
the Nginx configuration.

* upgraded SrcacheNginxModule to 0.21.

* bugfix: responses with a status code smaller than all the
status codes specified in the srcache_store_statuses
directive were not skipped as expected. thanks Lanshun Zhou
for the patch.

* feature: applied the invalid_referer_hash patch to the Nginx
core to make the $invalid_referer variable accessible in
embedded dynamic languages like Perl and Lua. thanks Fry-kun for
requesting this.

* updated the dtrace patch for the Nginx core.

* print out more info about the Nginx in-file bufs in the
tapset function "ngx_chain_dump".

The HTML version of the change log with lots of helpful hyper-links
can be browsed here:

http://openresty.org/#ChangeLog1002008

OpenResty (aka. ngx_openresty) is a full-fledged web application
server by bundling the standard Nginx core, lots of 3rd-party Nginx
modules and Lua libraries, as well as most of their external
dependencies. See OpenResty's homepage for details:

http://openresty.org/

We have been running extensive testing on our Amazon EC2 test cluster
and ensure that all the components (including the Nginx core) play
well together. The latest test report can always be found here:

Have fun!

proxy only certain assets based on host header? (2 replies)

We're trying to proxy only certain assets like png|jpg|css only when the host header is a certain DNS name. I tried to do this in the proxy.conf file using something the example below but it doesnt like the if statement. Is there a way to have nginx do what I am looking for?

if ($http_host = dnsname.com) {
location ~ ^/(stylesheets|images|javascripts|tools|flash|components)/ {
proxy_pass http://assethost
}
}

Nginx & Wordpress (1 reply)

alexandruv — Fri, 24 May 2013 02:44:10 -0400

Hello!

I'm having a hard time with nginx & wordpress. Specifically I installed/configured WP on http://www.busybabybook.com/blog/ and all seems to be ok EXCEPT for the fact that in the wp-admin/ I can't see: Media, Posts return an "Invalid post type", there are no Pages (but in fact I have 2: Contact and About).

Also, i would like to redirect www.busybabybook.com to www.busybabybook.com/blog/ but i've got no idea how to make this work without any problems in nginx.

This is my vhost:
http://pastebin.com/ugvLMQYd

Thank you in advance for helping out!

Nginx conf not working all of a sudden. What is the proper way to write this? (1 reply)

ajcr — Fri, 24 May 2013 04:09:47 -0400

First of all, let me state that I am brand new to nginx and I have not yet gotten to that point where I am able to diagnose issues on my own. So I am hoping one of you guys will be able to help me out!

I had a VPS running with nginx and the following file, but then I HAD to delete the installed operating system and reinstall Arch Linux. It was working with THIS EXACT configuration file (nginx.conf) and now after I reinstalled the VPS and reuploaded the same exact conf file (I made a backup of it before reinstalling) it refuses to work. When I "`sudo systemctl restart nginx`", it gives me the following error: `"Job for nginx.service failed. See 'systemctl status nginx.service' and 'journalctl -xn' for details."`

This is the conf file I am referring to:

#user html;
worker_processes 4;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;

events {
worker_connections 1024;
}

http {
include mime.types;
default_type application/octet-stream;

}

location ~ /\.ht {

}
}

include /usr/share/nginx/rescuechurchmiami.com/conf/*;

}

If I remove the following part:

server {
listen 80;
server_name www.brackishmedia.com brackishmedia.com;

#charset koi8-r;

#access_log logs/host.access.log main;

location / {

}

#error_page 404 /404.html;

error_page 500 502 503 504 /50x.html;
location = /50x.html {

}

location ~ \.php$ {
fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
fastcgi_index index.php;
root /usr/share/nginx/brackishmedia.com/html;
include fastcgi.conf;
}

location ~ /\.ht {
deny all;
}
}

include /usr/share/nginx/rescuechurchmiami.com/conf/*;

and do a `sudo systemctl restart nginx`, it works perfectly. However, I need those that other server block in there and that `include /usr/share/nginx/rescuechurchmiami.com/conf/*;` goes to a configuration file that is specifically for a WordPress install.

So these are the issues I am having. Any suggestions on fixing it? I don't even understand why it won't just work like it did on the former VPS anyway.

Thank you,
AJ

nginx conf access rule blocking certain url's (1 reply)

usazelf — Fri, 24 May 2013 04:07:38 -0400

We have url's like this: /demand/change_db_value/18050/13/.80/0/cost

Notice the /.80

In our nginx conf for our site we have this access rule: location ~ /\.ht { deny all; log_not_found off; access_log off; }

This rule produces this error in the logs: error.log: access forbidden by rule, server: oursite.tld, request: "GET /demand/change_db_value/18050/13/.80/0/cost HTTP/1.1"

We want to of course block access to any .htaccess files or files beginning with ".", but how do we make an exception for this particular url structure?

I have some issues with my nginx. It's related to forbidding hotlinking of my images to other websites. Since I host a lot of images I get a lot of my bandwidth leached . I will ask question i proper section. If there is some kind of IRC chat that would be great.

Rewriting (2 replies)

artem — Fri, 24 May 2013 13:00:02 -0400

Hi,
I use opencart with nginx+php-fpm. Sometimes it is necessary to redirect all clients, except admin (190.212.201.0/24), to "Service unavailable" page which is simple index.html file with logo, background image and some text, located in /unav directory.
Below some of nginx.conf

location / {

if ($remote_addr !~ '190\.212\.201\.[0-9]{0,3}') {
rewrite ^/(.*)$ /unav/$1 break;
return 403;
}
try_files $uri $uri/ @opencart;
}

location ^~ /unav {
}

location @opencart {
rewrite ^/(.+)$ /index.php?_route_=$1 last;
}

[...skipped...]

location ~ \.php$ {

try_files $uri =404;
fastcgi_read_timeout 60s;
fastcgi_send_timeout 60s;
include myphp-fpm.conf;

}

Problem is in rewriting.
This rule

rewrite ^/(.*)$ /unav/$1 break;

rewrite ONLY http://mysite.com/ request but in case http://mysite.com/index.php rewrite is none and request processed by location ~ \.php$ rule. Why??

Thanks!

NGINX error log format documentation (1 reply)

Jan Teske — Thu, 23 May 2013 15:32:01 -0400

Hey!

I want to parse NGINX error logs. However, I did not find any
documentation concerning the used log format. While the meaning of some
fields like the data is pretty obvious, for some it is not at all. In
addition, I cannot be sure that my parser is complete if I do not have a
documentation of all the possible fields. Since it seems you can change
the access log format, but not that of the error log, I really have no
idea how to get the information I need.

Is there such documentation?

I also posted this question on StackOverflow:
http://stackoverflow.com/questions/16711573/nginx-error-log-format-documentation/16711684

Thank you!

Объедините бэкенды в апстрим и тогда если один бэкенд упадёт или
вернёт ошибку, то запрос будет повторно отправлен на следующий бэкенд.

How to tell nginx to check dead backend in upstream adaptively? (no replies)

Ryan Chan — Thu, 23 May 2013 11:18:01 -0400

Hi,

Currently nginx will check every fail_timeout (default=10s) which is too
frequent when the backend server dead completely that require manually
replacement and it might take long time.

Definitely we can mark it as down in the config, but that is not an
automatic solution.

Is it possible to config nginx that it check adaptively?
e.g. start from 10s, then 20s, 40s, 60s etc?

Or are there any better approach?

Thanks.

Override Content-Type header with proxied requests (4 replies)

andrea.mandolo — Fri, 24 May 2013 04:58:49 -0400

Hi !!

i have a Nginx server that operates as a reverse proxy to a my bucket in Amazon S3.

Amazon S3 service could deliver contents with wrong Content-Type header,
so i would like to override this header by referring to file extension.

In other servers i have just configured the "types" block with all mime types mapped with file estensions,
but this approach only works when Nginx delivers contents directly (as a origin server).
If the server is a reverse proxy, doesn't add a new Content-Type header, but honors Content-Type (if exists) received by the origin.

Is it possible to override the content-type response header using "types" block? Is there any best practice to override content-type header by file extensions? Is "map" suggested for this purpose or using multiple "location" block is better?

Thanks in advance!!

[nginx] Memcached: stricten header validation. (no replies)

Memcached: stricten header validation.

An invalid memcached reply that started with '\n' could cause
segmentation fault.

An invalid memcached reply "VALUE / 0 2\r?ok\r\nEND\r\n" was
considered as a valid response.

In addition, if memcached reports that the key was not found,
set u->headers_in.content_length_n to 0. This ensures that
ngx_http_memcached_filter() will not be called while previous
code relied on always intercepting 404. Initialization of
ctx->rest was moved to where it belongs.

Apache + FPM load balancer CFG problems. (8 replies)

Renzo Racioppi — Fri, 24 May 2013 09:56:06 -0400

I'm having some problems with apache virtualhosts (vhosts scripts are set
in "/home/vhosts/$VHOST")...

ServerName www.site.com
ProxyPass / fcgi://192.168.56.202:9001/home/vhosts/www.site.com/
ProxyPassReverse / fcgi://192.168.56.202:9001/home/vhosts/www.site.com/
ErrorLog "logs/www.site.com-error_log"
CustomLog "logs/www.site.com-access_log" common

This configuration works, when apache receives a request for domain
"www.site.com" it will forward it to 192.168.56.202 backendserver and this
server finds the proper script at "/home/vhosts/www.site.com".

My problems are concerning load balancing. My configuration is:

ServerName www.site.com

BalancerMember fcgi://192.168.56.204:9001
BalancerMember fcgi://192.168.56.203:9001

ProxyPass / balancer://site/
ErrorLog "logs/www.site.com-error_log"
CustomLog "logs/www.site.com-access_log" common

But it is not working: requests will be forwarded to those backends, but I
can't figure out how to make those BalancerMember backends to point at
"/home/vhosts/www.site.com".
How should I do that?
