Nginx, location, alias and php - nginx

We are moving from lighttpd to nginx for HTTP/2.0 and having hard time configuring something which was so simple in lighttpd.
alias.url = ("/api" => "/web/myserver.com/develapi/")
We do this as we version control api and then just point url to appropriate folder. We do not want to use file links as well. Moreover, it's an one line command in lighttpd.
Here is how we are trying to achieve the same in NGINX.
location /api {
alias /web/myserver.com/develapi;
location ~ \.php$ {
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
}
}
However, this does not work as nginx passes /web/myserver.com/develapi as $document_root and /api/index.php as $fastcgi_script_name and hence resulting SCRIPT_FILENAME is wrong.
We then tried to use root
location /develapi {
root /web/myserver.com;
location ~ \.php$ {
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
}
}
This works as nginx passes /web/myserver.com as $document_root and /develapi/index.php $fastcgi_script_name and hence resulting SCRIPT_FILENAME is correct.
However, using root means either we have change existing structure or url. For this situation, using alias is the right solution but the way nginx implementing it, makes it tricky to use alias.
May be we are missing something trivial, any pointers will be appreciated.

I think problem is commonly answered/documented way to return SCRIPT_FILENAME
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
Reading more docs reveals $request_filename is a better way to go and works in both root and alias
fastcgi_param SCRIPT_FILENAME $request_filename;

It has been 3+ years... hope you have found the answer by now!
Here is a solution, for similar problem where I wanted to rewrite the fastcgi_script_name stripping off "wiki/" in front of them.
location /wiki {
alias C:/opt/mw/mediawiki-1.36.1;
index index.html index.php index.htm;
location ~ ^/wiki(/.*\.php(?:\?.*)?)$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$1;
include fastcgi_params;
}
}
Got the inspiration from: How to remove a path segment from NGiNX fastcgi_script_name?

How to write an NGINX rewrite which strips out everything from the URL after /filters/

We're running a Symfony application, which has a route of:
domain.tld/main-category/category/
For SEO purposes, they want to include filters in the URL like this:
domain.tld/main-category/category/filters/price:0-100
So basically we want the URL in the browser to remain the same, but in Symfony it should strip out everything after and including /filters/. So the route should remain "domain.tld/main-category/category/".
I tried this which does work, however I need it to work using Symfony routes but could not get it to work.
rewrite ^/.*/filters/.* /test.html last;
NGINX config:
location ~ ^/index\.php(/|$) {
include fastcgi_params;
fastcgi_pass php_project:9000;
fastcgi_read_timeout 600s;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT $realpath_root;
internal;
}
DISCLAIMER: This is a bit of a guess and might not work for you
PHP applications such as index.php often use the REQUEST_URI parameter to determine the "route". This is defined within your fastcgi_params file as:
fastcgi_param REQUEST_URI $request_uri;
One solution could be to manipulate this value using a map directive.
For example:
map $request_uri $myroute {
default $request_uri;
~*^(?<newroute>/.*)/filters/ $newroute;
}
server {
...
location ~ ^/index\.php(/|$) {
include fastcgi_params;
fastcgi_pass php_project:9000;
fastcgi_read_timeout 600s;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT $realpath_root;
fastcgi_param REQUEST_URI $myroute;
internal;
}
}
Note that the map must be placed outside of the server block.
You do not need to edit the fastcgi_params file, simply ensure that the fastcgi_param statements appear in the location block after the include statement.

install postfixadmin in a subfolder of a domain in nginx

I need to install postfixadmin as a subfolder of a domain hosted in nginx.
In other words, I'm trying to access postfixadmin using http://example.com/postfixadmin
Physically, the contents of the sites are stored this way:
example.com site in /var/www/example
Postfixadmin files in /var/www/postfixadmin
I've tried adding this within the server section of example.com:
location ~ /posfixadmin/ {
root /var/www;
index index.php;
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php5-fpm.sock;
}
The above works partially, php scripts are executed correctly, but css and image files found under /var/www/postfixadmin/css and /var/www/postfixadmin/images are not loaded.
I've checked at the generated html code and the links to css and image files in postfixadmin are called using relative paths, like this:
href="css/default.css"
I think nginx tries to get the css files from http://example.com/css instead of http://example.com/postfixadmin/css, that's why it's failing, I've tried something like this:
location /postfixadmin/css/ {
root /var/www/postfixadmin;
}
but the above doesn't work.
Any idea about how to fix this? Thanks in advance!
I know it's an old topic, but still: do not use "root" in a "location" block. Source: https://www.nginx.com/resources/wiki/start/topics/tutorials/config_pitfalls/
This works for me at the moment with the current PostfixAdmin 3.2 (which moved all the public facing stuff into the "public" subdirectory). Mind that I have defined the fastcgi_pass elsewhere, so this bit is not directly applicable.
location /postfixadmin {
alias /usr/local/www/postfixadmin/public;
location ~ ^(.+\.php)(.*)$ {
fastcgi_pass php;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $request_filename;
include fastcgi_params;
fastcgi_split_path_info ^(.+\.php)(.*)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
fastcgi_read_timeout 180;
fastcgi_buffers 4 256k;
fastcgi_buffer_size 128k;
}
location ~ \.php {
include /usr/local/etc/nginx/fastcgi_params;
fastcgi_param SCRIPT_FILENAME $request_filename;
fastcgi_pass php;
fastcgi_index index.php;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
location ~ /\.ht {
deny all;
}
}

fastcgi - passing information to scripts

I`m new with nginx and I dont know even what should I look for. My task is to force (I think it is) fastcgi to pass information (PATH_INFO) to the scripts. I have been told that I should add something in block after location ~ .php$ . Adding before fastcgi_pass xxx;
fastcgi_param PATH_INFO $fastcgi_path_info;
would made that happened ?
My location part config file looks like that:
location ~ ^/backend\.php/(.*)$ {
try_files $uri /backend.php?$1;
}
location ~ \.php$ {
# Zero-day exploit defense.
# http://forum.nginx.org/read.php?2,88845,page=3
# Won't work properly (404 error) if the file is not stored on this server, which is entirely possible with php-fpm/php-fcgi.
# Comment the 'try_files' line out if you set up php-fpm/php-fcgi on another machine. And then cross your fingers that you won't get hacked.
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
include fastcgi_params;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_pass xxx;
}

Configuration for lithium on nginx

I would like to deploy lithium on nginx server, however there are configurations provided only for Apache and IIS.
I've successfully written several nginx server configurations for various applications in past, but I'm struggling with this one.
Already asked this question on nginx and lithium forums, no luck.
This is best of what I've made so far.
root /var/servers/my_app/app/webroot;
location / {
index index.php;
try_files $uri $uri/ index.php;
}
location ~ \.php {
fastcgi_pass unix:/tmp/php.socket;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME /var/servers/my_app/$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_script_name;
}
Problem is on / (root page) every link gets index.php prepended, e.g. instead of
www.example.com/something
I get
www.example.com/index.php/something
Not sure if this even is nginx configuration related or rather something, that lithium does when it cannot detect Apache/IIS environment. Either way I cannot solve it.
Another thing, that when I access "www.example.com/test" (via direct URL input), the page renders correctly, however "www.example.com/test/" (with trailing slash) and "www.example.com/test/anything_here" is broken - all links gets appended to current URL e.g. pressing the same link creates this:
www.example.com/test/
www.example.com/test/test
www.example.com/test/test/test
EDIT: Updated configuration
(Sorry for much delayed edit, but I'm still stuck and recently restarted solving this)
root /var/server/my_app/app/webroot/;
index index.php index.html;
try_files $uri $uri/ /index.php?$args;
location ~ \.php {
fastcgi_pass unix:/tmp/php.socket;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME /var/servers/my_app/$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_script_name;
}
location ~/\.ht {
deny all;
}
}
As I mentioned in comments this now causes all links to have index.php included, it looks like:
www.example.com/index.php/something
www.example.com/index.php/stylesheet.css
I think your problem is that the try_files shouldn't be inside a location block.
Try the configuration shown here: http://li3.me/docs/manual/configuration/servers/nginx.wiki
I helped define it and have been using it locally and in production. It shouldn't cause any of the issues you're reporting.
Copying it below:
server {
listen IP_ADDRESS_HERE:80;
server_name DOMAIN.COM;
root /var/www/DOMAIN.COM/webroot/;
access_log /var/log/DOMAIN.com/access.log;
error_log /var/log/DOMAIN.com/error.log warn;
index index.php index.html;
try_files $uri $uri/ /index.php?$args;
location ~ \.php$
{
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include /etc/nginx/fastcgi_params;
}
location ~ /\.ht {
deny all;
}
}
As I suspected the problem was that Lithium relies on some environment variables, in this case - link generation, it uses PHP_SELF, which happened to be incorrect.
Solution:
fastcgi_param PATH_INFO $fastcgi_path_info;
Instead of previously incorrect:
fastcgi_param PATH_INFO $fastcgi_script_name;
So final configuration:
root /var/server/my_app/app/webroot/;
index index.php index.html;
try_files $uri $uri/ /index.php?$args;
location ~ \.php {
fastcgi_pass unix:/tmp/php.socket;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME /var/servers/my_app$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
location ~/\.ht {
deny all;
}

using .asmx using lighttpd and mono fastcgi

I have deployed a web service to a ubuntu server running lighttpd and fastcgi-mono-server2. The .asmx page loads correctly but when I test the method I get a 404.
My web service is called Import.asmx and my method is called download and the 404 comes back saying import.asmx/download does not exist
Using xsp2 the same service works perfectly
I assume it is something to do with how the /download gets served by lighttpd/fastcgi but cannot work out how to fix it.
Solved the 404 error... but now I have a 500.
Actually I was getting this error on every MyService.asmx/SomeMethod post calls. The solution [NOT REALLY] I've figured it out:
location ~ \.(aspx|asmx|ashx|asmx\/(.*)|asax|ascx|soap|rem|axd|cs|config|dll)$ {
fastcgi_pass 127.0.0.1:9001;
index index.html index.htm default.aspx Default.aspx;
fastcgi_index Default.aspx;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include /etc/nginx/fastcgi_params;
}
I've change it from only asmx to asmx/()*. Ok no 404 but now a 500: System.Web.HttpException: Method 'POST' is not allowed when accessing file '/Services/MyService.asmx/MyMethod'.
This findings give me some clues that nginx don't handle properly this kind of requests. After googling for almost 2 hours I've found a solution:
location ~ \.asmx(.*) {
fastcgi_split_path_info ^(.+\.asmx)(.*)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
include /etc/nginx/fastcgi_params;
fastcgi_index Default.aspx;
fastcgi_pass 127.0.0.1:9001;
}
I wasn't to far from it. Just add this location rule before the current you have and works fine.
I had the very same issue. Turned out to be default directive for serving 404 when not finding assets. Removed the following line:
try_files $uri $uri/ =404;
And add PATH_INFO as fastcgi param in /etc/nginx/fastcgi_params:
fastcgi_param PATH_INFO $fastcgi_path_info;
That fixed it for me. Hope it helps.
