Hello,
I am new to nginx and I am having trouble converting htaccess rewrite to nginx rewrite. Please help me convert the following mod_rewrites with a brief explanation. And should I put the nginx rewrite back into the .htaccess file or is there a designated config file to put the nginx location blocks?

<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>

RewriteEngine On

# Redirect Trailing Slashes...
RewriteRule ^(.*)/$ /$1 [L,R=301]

# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>

Caching fastcgi url (3 replies)

Hello,

I am looking for advice. I am using nginx to terminate SSL and forward the
request to php via fastcgi. Of all of requests I am forwarding to fastcgi
there is one particular URL that I want to cache, hopefully bypassing
communication with the fastcgi and php processes altogether.

- Would I need to define a separate location stanza for the URL I want to
cache and duplicate all of the fastcgi configuration that is normally
required? Or is there a way to indicate that of all the fastcgi requests
only the one matching /xyz is to be cached?

- If multiple request for the same URL arrive at around the same time, and
the cache is stale, they will all wait on the one request that is
refreshing the cache, correct? So I should only see one request for the
cached location per worker per minute on the backend?

- Since my one URI is fairly small, can I indicate that no file backing is
needed?

502 Error Issue (1 reply)

Hi All,

We recently migrated from apache to nginx.

OS - CetnOS 6
Nginx - 1.62 (4 CPU 8 GB RAM)
PHP-FPM (php 5.4.37) (4 CPU 8 GB RAM)
APC (Code Cache APC 3.1.13 beta)
Memcache (data cache)

I have upstream of 4 php servers for php-fpm service.

I am facing two issues:

1. I am getting 502 status code in access log means nginx generating 502 bad gateway error

2. Randomly connections got pile up on nginx up to 2500 and on php-fpm servers we do not see any load in top only 1-2 process seems to be running during that time and without taking any restart after 2-3 minutes it starts working normally and connections goes down to normal without taking any restart.


Please check nginx configuration in-line

Hi,

When compiling modsec, I came across the following -

"configure: WARNING: APR util was not compiled with crypto support. SecRemoteRule will not support the parameter 'crypto'"

Basically the rhel6 apr-devel rpm does not have crypto support. Trying to determine what are the ramifications are here.

Might anyone know what this means? Am having difficulty finding what this SecRemoteRule is.

Nginx support fot Weedfs !! (no replies)

Hi,

We're deploying WeedFS distributed filesystem for thumbs storage and
scalabilty. Weedfs is composed of two layers (Master, Volume). Master
server does all metadata mapping to track the corresponding volume server
against user requested file whereas volume server is the actual storage to
serve those requested files back to user via HTTP. Currently, weedfs
default webserver is being used as HTTP but it would be better to have
nginx webserver on volume servers for its low foot prints, stability and
robust response time for static .jpg files.

So we need to know if we can use nginx with weedFS ? Following is the
github we found, but need to confirm if it will fulfill our needs ?

https://github.com/medcl/lua-resty-weedfs

Thanks in advance.

Regards.

uWSGI - upstream prematurely closed connection while reading response header from upstream (1 reply)

June 24, 2015, 6:07 pm

Hi,

I have a script which runs for 70 seconds. I have NGINX connecting to it via uWSGI.

I have set "uwsgi_read_timeout 90;". However, NGINX drops the connection exactly at 60 seconds -

"upstream prematurely closed connection while reading response header from upstream"

My script continues to run and completes after 70 seconds, however my browser connection has died before then (502 error).

The option "uwsgi_read_timeout" does its job for anything less than 60 seconds (ie uwsgi_read_timeout 30;) and terminates with a 504 error as expected.

I don't quite understand what is catching the 502 bad gateway error even though I have instructed nginx to permit a uwsgi read timeout of 90

Other -

I also have set "keepalive_timeout 300 300;"

Any ideas as to the cause? I see numerous posts on the internet advising to use "uwsgi_read_timeout"

Thanks

Dash in request url messes up regex? (1 reply)

I am requesting the url /magento-check.php and it gives me the php
code instead of running it through fpm. Other php files work just
fine. Seems like the dash is screwing with the php regex location and
going through root location with try_files, serving the php code.

location ~* \.php(/.*)?$
{
if (!-e $request_filename) { return 404; }

fastcgi_pass unix:/var/run/php-fpm/blah.sock;
fastcgi_split_path_info ^(.*\.php)(/.*)?$;
include fastcgi.conf;

location /

try_files $uri $uri/ =404;

Using threads and poll in nginx module (no replies)

June 26, 2015, 3:08 am
$

Dear all,

I run into following problem when writing a module for nginx under Linux.

Within my module I have to use a library which internally uses multiple threads (pthreads) as well as poll.

When using/calling methods of this library in main initialization handler of my nginx module everything works fine.

Problem: But when I try to execute same code within other handling methods then the library is no longer working and method calls that internally use poll and threads seems to hang forever.

So my questions are:

1) Is it possible to use a library in an nginx module that internally uses poll and multiple threads?
2) If not, is there any approach to use such a library within a nginx module?

Thanks for your help.
Best regards Kline

Requests are not concurrent with SPDY and proxy_cache modules (1 reply)

Hi all,

I'm experiencing a strange behaviour on my SPDY tests.

I use nginx as a reverse proxy of a node.Js application.

I enabled spdy module and proxy_cache (nginx.conf file bellow) and I actually see no difference in requests speed. Requests are well handed by SPDY protocol (one TCP connection and multiple streams catched with tcpdump), but they should be concurrent and they actually are sequentials like without SPDY support.

Here are two screenshots of the waterfalls to see the behaviour
1) With proxy_cache support and SPDY not enabled :

Malware in /tmp/nginx_client (1 reply)

The software maldet, discovered some malware in the the /tmp/nginx_client directory, like this:

> {HEX}php.cmdshell.unclassed.357 : /tmp/nginx_client/0050030641
> {HEX}php.cmdshell.unclassed.357 : /tmp/nginx_client/0060442670

I did some research, and found out that indeed, there were some malicious code in them.

I did a extensive search in the sites, and nothing malicious was found, including the code that appeared in the tmp files.

Around the time the files were created, there were similar requests, to non existent Worpress plugins, and to a file of the Worpres backend.

Digging up a little, I found this: blog.inurl.com.br/2015/03/wordpress-revslider-exploit-0day-inurl.html

Basically an exploit for a Wordpress plugin vulnerability, (it doesn't affect my sites, though), that do similar requests to the ones I found.

One of those, is a post request that includes an attacker's php, file that thanks to this vulnerability will be uploaded to the site and it can be run by the attacker.

So what it seems to be happenning is that nxing is caching post requests with malicious code, that later is found by the antimalware software.

Could this be the case? I read and seems that Nginx does't cache post request by default, so it seems odd.

Is there a way to know if that tmp files are caching internal or external content?

I will be thankful for any info about it.

Nginx is working as reverse proxy only.


This is a bit of another file that was marked as malware:

Documentation of buf struct (no replies)

I am not very clear on the purpose of different data members within the buf structure.(appended below)

After looking through the code, I can figure out the purpose of 

- pos,last (sliding window) 

- file_pos, file_last, start, end ,(data start and end)

- tag, (which module owns this buf)

- file (name of the file if any associated with the data)

- memory(cannot be released by any module that processes the buf).

- mmap (buf is memory map)

- last_in_chain(last in the chain of bufs)

- last_buf(last in the response)

- For temporary: can the temporary buffer be released by any module that processes it or can it be released by only the module that owns it as indicated in the tag



It will be good if the purpose of other data members is described also. Thanks for any inputs


struct ngx_buf_s {    u_char          *pos;    u_char          *last;    off_t            file_pos;    off_t            file_last;

I have created a reverse proxy for 2 web servers both are running about 10 sites each, they use to be on seperate external IP's but now need to be behind the same one.

Using Nginx I setup a reverse proxy on a seperate VM, Its seems to work but one site is refusing to go to the correct server.

I have nothing in /conf.d/ I am using /sites-available and /sites-enabled, each site has its own config file. Im using proxy_pass with the servers IP address. What am I doing wrong?

server {

location / {
proxy_pass http://10.0.0.110/;

Can thread pool improve performance for such scenario (3 replies)

Hi All:
I am using Nginx as a reverse proxy which provide a web API (HTTP GET
) to client.
and the backend application will get request from nginx and do some
time-consuming processing (1-2 seconds) then response result to nginx,
Nginx return result to client.
I think this is synchronize operation.

As I know, Nginx import thread pools feature, so is it useful for my
scenario and improve performance?

Rejoice,I Desire!

slow response times (no replies)

We are currently using nginx/1.7.10 @Ubuntu12.04 for serving high load
webapp with about 12-15k QPS mostly tiny requests / HTTP/1.1 keep-alive
mode. Nginx is used as proxy for http backends. From time to time we
are noticing traffic gaps and during this time nginx answers very slowly
(up to 20-25s) across all virtual hosts. There are no any error
messages in general error log and also server has much of resources
available. The nature of service is that http backends have very low
read/connect proxy timeout value (40ms) and nginx should be able to send
static file during error interception, those timeout happen very often
(2-3k during a second) But unfortunately we cant make it stable enough
to provide fast static answer during backend slowness periods since it
hangs and answers very slow

Location configuration:

access_log off;

error_page 500 501 502 503 504 408 404 =200 /file.dat;

include proxy_params;
proxy_intercept_errors on;
proxy_cache off;
proxy_redirect off;
proxy_pass_request_body on;
proxy_pass_request_headers on;
proxy_next_upstream off;
proxy_read_timeout 40ms;
proxy_connect_timeout 40ms;
proxy_send_timeout 40ms;

set $args src=g2;
proxy_pass http://upstream/;
proxy_http_version 1.1;
proxy_set_header Connection "";
}




Stub_status during normal operation:
Active connections: 831
server accepts handled requests
919758 919758 945641607
Reading: 0 Writing: 44 Waiting: 787

I can share any needed debug/stats info for sure.

Thank you for your cooperation

Static content (3 replies)

Hi,
I have NGinx 1.8.0 installed successfully and configured NGinx... with upstream servers provided. NGinx and Services are deployed on separate machines. Now, when an request is made via NGinx, the service is invoked resulting in UI with no static content loaded.

I have tried root, rewrite directives... to specify the static content path on another server (workspace.corp.test.no), which didn't helped. I might be wrong with configuration. Pls. assist


server {
listen 80;
server_name workspace.corp.test.no;

location ~"*\.(js|jpg|png|css)$" {
root /workspace/WEB-INF/classes/static;
expires 30d;
}

location /{
proxy_pass http://workspace.corp.test.no/workspace/agentLogin/;
}
}


And, the above configuration is expecting static content on the server where NGinx is installed, when an request is made. But, I expect the static content to be expected from remote server.



Best regards,
Maddy
