warning: `sys_nerr' is deprecated;

This is normal: nginx has to use the deprecated sys_errlist[] and sys_nerr in signal handlers because strerror() and strerror_r() functions are not Async-Signal-Safe.

I tried to see which version is nginx.net using right now..

HTTP/1.1 200 OK
Server: nginx/0.6.31
Date: Fri, 06 Feb 2009 08:21:44 GMT
Content-Type: text/html
Content-Length: 5675
Last-Modified: Mon, 02 Feb 2009 11:03:48 GMT
Connection: keep-alive
Accept-Ranges: bytes

I think there’s no such a security upgrade since 0.6.31 to 0.6.35.. But if you want to make sure, please see the changelog

I actually have implement nginx + vbseo on the forum that I maintained. You can see them here and here

How to create a nginx rewrite rule that is working for vBulletin and vbSEO plugins?

This’s the nginx configuration that’s working for vBulletin and vbSEO

location / {
rewrite ^/((urllist|sitemap_).*\.(xml|txt)(\.gz)?)$ /vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 last;

if ($request_filename ~ “\.php$” ) {
rewrite ^(.*)$ /vbseo.php last;
}

if (!-e $request_filename) {
rewrite ^/(.*)$ /vbseo.php last;
}

}

Any comments please welcome

By default they only giving us the rewrite rules for Apache

Default nginx rewrite rules without WP Super Cache plugin

rewrite ^.*/files/(.*) /wp-content/blogs.php?file=$1;
if (!-e $request_filename) {
rewrite ^.+?(/wp-.*) $1 last;
rewrite ^.+?(/.*\.php)$ $1 last;
rewrite ^ /index.php last;
}

WP Super Cache plugin will not able to run with that rewrite rules. So now the question is, How can we make nginx rewrite rule to work with WP Super Cache plugin ?

Here’s my nginx config that’s running very well

if (-f $request_filename) {
break;
}

if (-d $request_filename) {
break;
}

rewrite ^.*/files/(.*) /wp-content/blogs.php?file=$1;

if (!-e $request_filename) {
rewrite ^.+/?(/wp-.*) $1 last;
rewrite ^.+/?(/.*\.php)$ $1 last;
rewrite ^(.+)$ /index.php?q=$1 last;
}

set $supercache_file ”;
set $supercache_uri $request_uri;

if ($request_method = POST) {
set $supercache_uri ”;
}

if ($query_string) {
set $supercache_uri ”;
}

if ($http_cookie ~* “comment_author_|wordpress|wp-postpass_” ) {
set $supercache_uri ”;
}

if ($supercache_uri ~ ^(.+)$) {
set $supercache_file /wp-content/cache/supercache/$http_host/$1index.html;
}

if (-f $document_root$supercache_file) {
rewrite ^(.*)$ $supercache_file break;
}

Congratulations that you have successfully make your nginx to work with WP Super Cache plugin

But I don’t know why it’s not appear on search engine.

You can read more about how to install/recompile nginx to support upstream hash module

This’s how to recompile nginx with upstream hash module

We need to recompile nginx to support upstream hash module. Because debian based nginx, doesn’t have this module loaded. And we need to download the module from here

First of all, we need to install the software that’s needed to recompile a .deb packages

apt-get install build-essential debhelper fakeroot

Then go to /usr/local/src directory

cd /usr/local/src

Now we need to download the source package of nginx

apt-get source nginx

apt-get build-dep nginx

Before we go to the next step, we need to patch nginx with the patch given

cd /usr/local/src/nginx-0.6.32/

patch -p0 < /path/to/upstream/hash/directory/nginx.patch

Then we go to nginx directory

cd /usr/local/src/nginx-0.6.32/debian

Edit rules to add upstream hash module

vim rules

Add –add-module=/path/to/upstream/hash/directory

Go back to nginx directory

cd ..

Now it’s time for us to compile nginx and take a glass of coffee while waiting

dpkg-buildpackage -rfakeroot

If you found error like

(WARNING: Failed to sign .dsc and .changes file)

That means normal. Just ignore the error msg

Now go back to /usr/src directory

cd /usr/src

You should see a file called nginx_0.6.32-3_i386.deb

Then install our new compiled nginx package

dpkg -i nginx_0.6.32-3_i386.deb

Then lastly we add “fair” module on our nginx.conf

Example

upstream backend {
server server1;
server server2;
hash $http_cookie_username;
}

Congratulations that you have install nginx with fair proxy module on your debian

If you don’t want to do that installation, you can download directly precompiled debian nginx package that’s already patched for upstream hash module ]]> http://lumanau.web.id/2008/10/18/building-nginx-package-with-upstream-hash-module-on-debianubuntu.html/feed 1 http://lumanau.web.id/2008/10/17/building-a-nginx-package-with-fair-proxy-module-on-debianubuntu.html http://lumanau.web.id/2008/10/17/building-a-nginx-package-with-fair-proxy-module-on-debianubuntu.html#comments Fri, 17 Oct 2008 09:09:07 +0000 admin http://www.lumanau.web.id/?p=59 This’s how to recompile nginx with fair proxy module
