Force linking to static archives during make? (4 replies)

This should be my last build question.

$ ./auto/configure --with-http_ssl_module ...
--with-cc-opt="-I/usr/local/ssl/include"
--with-ld-opt="-L/usr/local/ssl/lib /usr/local/ssl/lib/libssl.a
/usr/local/ssl/lib/libcrypto.a -ldl"
....
$ make
....

Results in the following. Note that OpenSSL is still dynamically linked:

$ ldd objs/nginx
linux-vdso.so.1 => (0x00007fffd0dfe000)
libdl.so.2 => /lib64/libdl.so.2 (0x0000003ebf600000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x0000003ebfa00000)
libcrypt.so.1 => /lib64/libcrypt.so.1 (0x0000003ed3e00000)
libpcre.so.1 => /lib64/libpcre.so.1 (0x0000003ec0a00000)
libssl.so.1.0.0 => not found
libcrypto.so.1.0.0 => not found
libz.so.1 => /lib64/libz.so.1 (0x0000003ebfe00000)
libc.so.6 => /lib64/libc.so.6 (0x0000003ebf200000)
/lib64/ld-linux-x86-64.so.2 (0x0000003ebea00000)
libfreebl3.so => /lib64/libfreebl3.so (0x0000003ec7a00000)

*****

Adding -Bstatic does not help even though its clearly on the link command line:

$ ./auto/configure --with-http_ssl_module ...
--with-cc-opt="-I/usr/local/ssl/include" --with-ld-opt="-Bstatic
-L/usr/local/ssl/lib /usr/local/ssl/lib/libssl.a
/usr/local/ssl/lib/libcrypto.a -ldl"
....
$ make
....
objs/src/http/modules/ngx_http_upstream_keepalive_module.o \
objs/ngx_modules.o \
-Bstatic -L/usr/local/ssl/lib /usr/local/ssl/lib/libssl.a
/usr/local/ssl/lib/libcrypto.a -ldl -lpthread -lcrypt -lpcre -lssl
-lcrypto -lz
....
$ ldd objs/nginx
linux-vdso.so.1 => (0x00007fffd4fc6000)
libdl.so.2 => /lib64/libdl.so.2 (0x0000003ebf600000)
...
libssl.so.1.0.0 => not found
libcrypto.so.1.0.0 => not found

*****

Omitting -L/usr/local/ssl/lib results in a failed configure.

How does one force nginx to use static linking for a library?

Thanks in advance.

checking for OpenSSL library ... not found

../auto/configure: error: SSL modules require the OpenSSL library.
You can either do not enable the modules, or install the OpenSSL library
into the system, or build the OpenSSL library statically from the source
with nginx by using --with-openssl=<path> option.
</snip>

*****

I believe OpenSSL is present (I just built it from sources):

$ ls /usr/local/ssl/
bin certs include lib man misc openssl.cnf private

$ ls /usr/local/ssl/lib/
engines libcrypto.a libssl.a pkgconfig

*****

Here was my configure. $THIS_USER and $THIS_GROUP was set properly to
my login and group.

../auto/configure --with-debug --with-http_ssl_module
--prefix="$THIS_DIR/ac" --http-proxy-temp-path="$THIS_DIR/ac/temp"
--user="$THIS_USER" --group="$THIS_GROUP"
--with-cc-opt="-I/usr/local/ssl/include"
--with-ld-opt="/usr/local/ssl/lib/libcrypto.a
/usr/local/ssl/lib/libssl.a /usr/local/ssl/lib/libcrypto.a

*****

I believe --with-cc-opt and --with-ld-opt is the preferred (required?)
way to do things for local/custom OpenSSL
(http://mailman.nginx.org/pipermail/nginx/2010-April/019644.html).

Does anything look out of place?

nginx misbehaviour in conjunction with non-ASCII characters (2 replies)

December 19, 2013, 6:19 am
$
0
0
Found a bug in implementation of MOVE and COPY (webdav) methods. It happens if destination header contains non-ASCII characters (that need to be escaped with "%").

An example:

Rename (=MOVE) file "<www-root>/TheCore.ogm" to "<www-root>/The_Core.ogm":

Request header:
--> MOVE http://andinas/TheCore.ogm HTTP/1.1
--> Destination: http://andinas/The_Core.ogm
Response header:
--> HTTP/1.1 204 No Content
--> Server: nginx/1.5.6
Result: File renamed to "The_Core.ogm". Fine!

Now rename (=MOVE) file "<www-root>/andinas/The_Core.ogm" to "<www-root>/andinas/The_ Core.ogm" (notice the blank after the underscore, but the same is true for äöüß and the like!):

Request header:
--> MOVE http://andinas/The_Core.ogm HTTP/1.1
--> Destination: http://andinas/The_%20Core.ogm
Response header:
--> HTTP/1.1 204 No Content
--> Server: nginx/1.5.6
Result: File renamed to "The_%20Core.ogm". Not so fine!

The escaped blank is treated by nginx MOVE as if it was not escaped!


Found a similar issue with this config-file line:
--> if ( $http_destination ~ https?://[^/]+/(.*) ) { set $httpdest http://localhost:8008/$remote_user/$1; }

(for this (working!) code that makes the destination header ready for proxy_pass to another webdav server with user dependent base folders (pyWebDav allows only one user :-/):
--> proxy_set_header Destination $httpdest;
--> proxy_pass http://127.0.0.1:8008/$remote_user$request_uri;
).

Here again, if $http_destination contains the perfectly correct escaped characters from the webdav client, the resulting $httpdest will additionally escape the "escape" characters.

Example:
Destination File = "<www-root>/The_ Core.ogm"
$http_destination = "http://andinas/The_%20Core.ogm" (correct)
$httpdest = "http://andinas/The_%2520Core.ogm" (wrong!)

Obviously here the highly undesirable transformation happens during the regex matching. But why? Can I switch that off somehow?

Workaround: Use perl function to replace "%25" by "%". Use the undocumented "r->variable()" for that!


If you are still reading :-): There are two very funny things about the
--> proxy_pass http://127.0.0.1:8008/$remote_user$request_uri;
line:
1) You cannot use localhost here. nginx needs a resolver as soon as there is a variable in the string. And at least I didn't manage to find a resolver that can resolve localhost.
2) Nowhere on the internet it's been said, that you need to add $request_uri to that line, but you do need! And it even must not be $uri, because that one has the same escaping issues like the other things I mentioned above.


OK, now I'm done ;-). Please help!

Hi

I'm using proxy_cache to mirror my files with the configuration below

proxy_cache_path  /var/cache/nginx/image levels=1:2 keys_zone=one:10m inactive=7d     max_size=100g;

Our backend server has the expires header set to 600secs

Is that posibble for us to also delete the cache files located at /var/cache/nginx/image depends on the backend expire header?

[PATCH] SPDY: support for SPDY v3 (no replies)

Hi,

We have just implemented the support for SPDY v3 in nginx, with flow
control (upload and download), and a switch option between SPDY v2 and
SPDY v3.

This patch is for Nginx-1.5.8.

The directives we added are:

spdy_version
syntax: spdy_version [2|3]
default: spdy_version 3
context: http, server
Specify the version of current SPDY protocol.

spdy_flow_control
syntax: spdy_flow_control on|off
default: spdy_flow_control on
context: http, server
Turn on or off with SPDY flow control.

spdy_init_recv_window_size
syntax: spdy_init_recv_window_size size
default: spdy_init_recv_window_size 64k
context: http, server
Specify the receiving window size for SPDY. By default, it's 64K. It
will send a WINDOW UPDATE frame when it receives half of the window
size data every time.

Hope this patch is helpful. Have fun :-)

Thank you.

trying to understand fastcgi (no replies)

I was trying to understand the fastcgi forwarding. The example shows:

server {
server_name .website.com;
listen 80;
root /home/website/www;
index index.html;
location / {
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_script_name;
include fastcgi_params;
}
}

in SCRIPT_FILENAME, does $document_root == root /home/website/www; ?
and what value is usually stored in (SCRIPT_NAME)
$fastcgi_script_name? i don't understand what script SCRIPT_NAME
refers to. Am i suppose to set it or does it set itself?

It also says QUERY_STRING $query_string; is needed for configuring
fastcgi. But this example clearly hasn't used it?

Is the idea to have fastcgi_param for only the variables i want to
include? or is this config simply defining them with a value by
default?

Redirect loop fixed, I need a better rule format (no replies)

Hello everyone,

I have a little problem on hand, related to redirect loop for a specific location:
server {
listen 192.168.1.2:443 spdy ssl default_server;
...
location ^~ /alpha {
return 301 https://www.domain.com$request_uri;
}
...
}
I would like to redirect URL's of this format:
https://www.domain.com/alpha/delta/[more of $request_uri]
To:
https://www.domain.com/delta/[more of $request_uri]

I can access fine the https://www.domain.com/delta/... directory. When the GET is performed on https://www.domain.com/alpha/, it tries to use the old REQUEST URI which is obviously wrong. I solved the issue this way:
location ^~ /alpha {
location /alpha {
return 301 https://www.domain.com/;
}
location ~ ^/alpha/(.+)$ {
return 301 https://www.domain.com/$1;
}
}

Is there a better (more compact) way to achieve the same results?
With the rules listed above, I tell Nginx to redirect /alpha or /alpha/ to /.
If the $request_uri contains something after /alpha, I grab the part of $request_uri after /alpha and push it to /.

Thank you for helping me make this configuration part better.

Redirect loop in combination with https and apache (no replies)

December 23, 2013, 2:08 am
$

Hi,

We have a setup with tomcat/apache and nginx.

When a redirect occurs from the application from https to http, the nginx
gets trapped in a redirect loop.

In the apache configuration we have this setting:

<IfModule mod_expires.c>
ExpiresActive On
ExpiresDefault "access plus 1 month"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
..... more mimetypes

The nginx configuration has this location

location / {
proxy_pass http://def-t-site1/;
proxy_http_version 1.1;
proxy_hide_header Expires;
proxy_hide_header Last-Modified;
proxy_redirect off;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_cache http_def;
proxy_cache_key $scheme://$host$uri$is_args$args;
# proxy_cache_key "$scheme://$host$request_uri";
proxy_cache_valid 200 302 10m;
proxy_cache_valid 404 1m;
add_header Cache-Control "public";
add_header X-Cache-Status $upstream_cache_status;
add_header X-Via $hostname;
}

a similar setting we have for 443 port (https).

If we remove ExpiresDefault "access plus 1 month" from apache, the redirect
loop does not occur. The cache of nginx uses a TTL of 1 month after the
redirect occurs. This causes a redirect loop, since the https request is
cached as well.


So far, we tried several things
- proxy_cache_valid 200 301 0m;
No change in the TTL. The redirect loop is not solved, and the TTL is still
a month.

Then we tried to configure the expire headers in nginx. That solves the
redirect, but unfortunately
the expire headers are not set. We tried for instance:

if ($upstream_http_content_type ~ "image/jpeg") {
expires 2m;
}

or
map $upstream_http_content_type $new_cache_control_header_val {
default $upstream_http_cache_control;
"~*image/jpeg" "max-age=120, must-revalidate";
}

but these settings did not have any effect on the TTL of the images.

So, is there a way to avoid the redirect loop and set the expire header per
mimetype in nginx ?

Thanks!

Serving default error pages with 'proxy_intercept_errors on' (2 replies)

Hello,

I'm running nginx v1.4.1 on OpenBSD 5.4 and I'd like to use
'proxy_intercept_errors on' directive without providing my own error
pages. In other words, instead of forwarding page content from the
backend server, just use the error pages that nginx generates by
default.

This isn't supported normally, however the following configuration
seems to achieve the desired result (though you have to list the error
codes explicitly):

error_page 403 404 ... @error;
location @error { return 444; }

I didn't actually know what this would do until I tried it. I assume
that when a matching error code is received from the backend server,
nginx closes the proxy connection without reading the body and creates
a new internal request to @error, which is immediately closed without
a response. Thus, there is no body to send to the client, so it falls
back to the default behavior.

The question is whether this behavior is an accident and may change in
a future version, or if it's an acceptable way of intercepting errors
without providing custom error pages?

How do I disable DNS Caching and DNS Reverse Lookup in Nginx ? (3 replies)

Hello all

Ive been assigned a task to set up an ipv6 to ipv4 reverse proxy for my company. I decided to use nginx to do the job. I found the following article online which describes how to configure nginx as a reverse proxy :

http://www.kutukupret.com/2011/05/02/nginx-as-reverse-proxy-ipv6-to-ipv4-website/

So this is how i set up my reverse proxy. First off I installed RHEL 6.5 on a VM and installed nginx on it. Second off I set up an AAAA record in our DNS as a test FQDN so that I could use that FQDN to connect through the proxy to an IPV4 website. For example, the FQDN is ipv6.mycoolsite.com and the IPv4 website is www.yourcoolsite.com. I set up the default.conf file as such:

<quote>

server {
listen [::]:80 default ipv6only=on;
server_name ipv6.mycoolsite.com;

#charset koi8-r;
access_log /var/log/nginx/log/ipv6.mycoolsite.com.access.log main;
error_log /var/log/nginx/log/ipv6.mycoolsite.com.error.log;
location / {
# root /usr/share/nginx/html;
# index index.html index.htm;
proxy_pass http://www.yourcoolsite.com;
proxy_redirect default;
proxy_set_header X-Real-Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_read_timeout 120;

}

}

</quote>

Here are the issues that I am currently having:

When I run the nginx service and I test the FQDN on an ipv6 enabled computer, I am able to access the IPV4 website www.yourcoolsite.com. But when I change the proxy_pass FQDN to a different IPV4 website in the config file and reload the service, ipv6.mycoolsite.com still connects to www.yourcoolsite.com and not to the new IPV4 FQDN. I think its loading a cached copy of www.yourcoolsite.com instead of loading the new IPV4 FQDN. When it finallly does load the new site, it does so REALLY slowly. I think this is due to reverse DNS lookup occuring!

Now what I am trying to figure out here is what is causing the caching to occur and the slow loading times? How do I go about disabling DNS caching as well as the reverse DNS lookup? I want to be able to connect the IPV4 website specified in the default.conf file when ever I change the file and reload the service. I dont want to connect to a cached copy of the previous IPV4 entry !

any help will be greatly appreciated!!




Oh and when I check the access logs after I test the proxy, this is what I see:

I have setup a wildcard subdomain server(many subdomains)
server {
listen 80;
server_name ~(?<subdomain>.*).localhost;
...
...
}

I want to make the subdomain apart of the query in the backend

when we visit http://clothes.localhost/
backend query
http://localhost/script.php?sd=clothes

or we visit http://jackets.localhost/large/blue/
backend query
http://localhost/script.php?sd=jackets&size=large&colour=blue

I have tried for 5 hours now, Modifying rewrite and return as many ways possible, Multiple errors such as

rewrite ^ http://$subdomain.localhost/script.php?x=$subdomain permanent;

http://clothes.localhost/script.php/script.php/script.php/script.php/script.php/script.php/script.php/script.php/?sd=clothes?sd=clothes&sd=clothes?sd=clothes&sd=clothes?sd=clothes&sd=clothes?sd=clothes&
or
http://localhost/localhost/localhost/localhost/localhost

etc etc(I have tried many more tweaks but didnt record all as I went along)

Thanks in advance for any intention to help or answers given.

problems setting ttl on single image... (2 replies)

I'm trying to enable a 10 minute autorefresh for my webcam which you can
see at http://www.diamondharbour.org.nz/Local-Weather.html

Server runs nginx 1.4.4 ( and an ancient CMS called Etomite ).

Here's the WPT result http://www.webpagetest.org/result/131229_HV_MK2/

Here's a snippet of my config...

location = /assets/Photo\ Gallery/Weather/current\.jpg {
expires 10m;
log_not_found off;
}

location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
expires max;
log_not_found off;
}

Why is is not setting a 10 minute expiry - the webpagetest report should
pick up on it??? I'm sort of expecting that it may have something to do
with the space in the URL?

Any pointers gratefully received (:
