Apache mod_rewrite to Nginx rewrite rules - apache

My site is running on Nginx and I am trying to add a software in the sub-directory of the site that uses Apache's mod_rewrite rules. E.g. www.mydomain.com/mySubfolder
Here is the Apache .htaccess
#Options -Indexes
<ifModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/system.*
RewriteRule ^(.*)$ index.php?/$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ index.php?/$1 [L]
</ifModule>
So far I managed to get the main page to work but when requesting the login page, it is causing a URL redirect loop. E.g. www.myDomain.com/login
With this:
location /mySubfolder {
if (!-e $request_filename) {
rewrite ^(.*)$ /mySubfolder/index.php?q=$1 last;
break;
}
}
I have been reading and trying to learn how to convert Apache to Nginx and even used the .htaccess to Nginx converter I found at http://winginx.com/htaccess but the tool doesn't seem to recognize the %{REQUEST_URI} ^/system.* part. Upon my research and study, I came up with:
location /mySubfolder {
if ($request_uri ~ "^/(system.*)$") {
rewrite ^/(.*)$ index.php?/$1 last;
}
if (!-e $request_filename) {
rewrite ^(.+)$ /mySubfolder/index.php?q=$1 last;
break;
}
}
I am a complete noob at this and was even wondering if I am even close to accomplish this conversion to work. Please help.
Thank you.

You've basically taken the wrong approach to use in Nginx.
Although it is kind of natural to assume that the rewrite rules in Apache would be mapped to the rewrite in Nginx, they aren't. Instead they are mostly mapped to the location rules.
Your block for mySubfolder should look like:
location ^/mySubfolder {
try_files /mySubfolder/index.php?$args =404;
}
You aren't actually rewriting anything - you are just telling nginx that any requests that start with /MySubfolder should be served by the files listed in try_files. btw you have to tell Nginx to pass the query string through which is what the args is doing.
You can append the original URL (i think) though it may be easier just to use $_SERVER['REQUEST_URI'] inside your script.
I believe the rewrite rule you have to the same start URI is causing the /mySubFolder to keep matching.
In Nginx rewriting is only used when you want to make external URL paths be served by different internal urls, and normally the rewrite rule is not inside a location block.
For example I have a file server, that serves up images and other files. I have these rewrite rules in the server block:
rewrite ^/image/(\d+)/(\w+)/(.+)\.([^\.]*)$ /proxy/proxyImage.php?typeID=$1&mode=$2&imagePath=$3.$4&resizeAllowed=TRUE&type=image last;
rewrite ^/image/(\d+)/(.+)\.([^\.]*)$ /proxy/proxyImage.php?typeID=$1&imagePath=$2.$3&resizeAllowed=TRUE last;
rewrite ^/file/(\d+)/(.+)\.([^\.]*)$ /proxy/proxyFile.php?typeID=$1&imagePath=$2.$3&resizeAllowed=FALSE last;
to make the external URLs look nice. But then they are all served by the location block:
location ~* ^/proxy {
try_files $uri =404;
fastcgi_pass unix:/opt/local/var/run/php54/php-fpm-images.sock;
include /documents/projects/intahwebz/intahwebz/conf/fastcgi.conf;
}
The location block doesn't need to know about the URL rewrites because they are done before the location block is encountered.

How to convert rewrites from advanced .htaccess to nginx conf rules

Recently switched to nginx from Apache. This works under apache perfectly fine, but don't know how to add it for nginx. Have tried htaccess to nginx converters, but they get me redirect loop.
I have WordPress in root and custom code under subdirectory.
This is the working .htaccess file on Apache:
# rewrite engine on and setting up base
RewriteEngine On
RewriteBase /leffa/
# replace + with _
RewriteRule ^(.+?)\+(.+)$ $1-$2 [R=301,L,NE]
# external redirect from action URL to pretty one
RewriteCond %{THE_REQUEST} /index(?:\.php)?\?q=([^\s&]+)&(kuvauksesta)= [NC]
RewriteRule ^ %1/%2? [R=302,L,NE]
RewriteCond %{THE_REQUEST} /index(?:\.php)?\?q=([^\s&]+)\s [NC]
RewriteRule ^ %1? [R=302,L,NE]
# skip all files and directories from rewrite rules below
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ - [L]
# internal forward from pretty URL to actual URL (extra parameter)
RewriteRule ^([^/.]+)/([^/.]+)?$ index.php?q=$1&$2=1 [L,QSA]
# internal forward from pretty URL to actual URL
RewriteRule ^(.+)/?$ index.php?q=$1 [L,QSA]
This rewrites all the urls like http://www.rollemaa.org/leffa/index.php?q=the+boy to pretty ones like http://www.rollemaa.org/leffa/the-boy.
The situation is, I have main file set up like this:
server {
listen 80;
access_log /var/log/nginx/rollemaa.access.log;
error_log /var/log/nginx/rollemaa.error.log;
root /var/www/rollemaa.org/public_html;
index index.html index.htm index.php;
server_name rollemaa.org www.rollemaa.org;
include hhvm.conf;
include global/wordpress.conf;
# Ensure requests for pagespeed optimized resources go to the pagespeed
# handler and no extraneous headers get set.
location ~ "\.pagespeed\.([a-z]\.)?[a-z]{2}\.[^.]{10}\.[^.]+" { add_header "" ""; }
location ~ "^/ngx_pagespeed_static/" { }
location ~ "^/ngx_pagespeed_beacon" { }
# Static File Caching
location ~* .(jpg|jpeg|png|gif|ico|css|js)$ {
expires 365d;
}
#location /leffa/ {
#try_files $uri $uri/ /leffa/index.php?q=$args;
#rewrite ^/leffa/(.+?)\+(.+)$ /leffa/$1-$2 redirect;
#rewrite ^/leffa/(.*)$ /leffa/%1/%2? redirect;
#rewrite ^/leffa/(.*)$ /leffa/%1? redirect;
#if (-e $request_filename){
# rewrite ^/leffa/([^/.]+)/([^/.]+)?$ /leffa/index.php?q=$1&$2=1 break;
#}
#rewrite ^/leffa/(.+)/?$ /leffa/index.php?q=$1 break;
#}
}
As you can see, I have commented out the rewrite part, because it's not working.
Any nginx gurus out there who could help me with this? Much appreciated in advance!
You can use the following rewrite rule.
location /leffa/ {
index index.php index.html;
rewrite ^/leffa/([^/]*)/?$ /leffa/index.php?q=$1;
}
It will rewrite URLs like /leffa/the-boy/ and /leffa/the-boy to /leffa/index.php?q=the-boy. URLs with sub-subdirectories such as /leffa/the-boy/something-here will be ignored.
Note: + in the URL is not converted to a space (as it would be when directly accessing /leffa/index.php?q=the+boy). Accessing /leffa/the+boy/ will result in the query parameter q being "the+boy".
If you want to use spaces in the query string, you will have to use the %20 URL encoded format for spaces. /leffa/the%20boy and /leffa/the%20boy/ will result in the query parameter q being "the boy".

How to rewrite nginx to execute a php file before serving static content?

I am trying to do this in nginx but I just cannot get it to work:
# protect images
RewriteCond %{REQUEST_FILENAME} \.(bmp|gif|ico|jpe|jpeg|jpg|png)$
RewriteRule .* /path-to-file.php [L,QSA]
Tried it with try_files and rewrite, any advice is appreciated!
To rewrite all image URIs to a specific PHP script, you could use a regex location and an internal rewrite:
location ~* \.(bmp|gif|ico|jpe|jpeg|jpg|png)$ {
rewrite ^ /path/to/file.php;
}

Convert htaccess rules to nginx rules

I have these apache (htaccess) rules and I want to convert them to nginx rules. I have tried a lot of combinations but in vain.
You have the rules below:
RewriteRule ^candybooru/_images/([0-9a-f]{2})([0-9a-f]{30}).*$ /candybooru/images/$1/$1$2
RewriteRule ^candybooru/_thumbs/([0-9a-f]{2})([0-9a-f]{30}).*$ /candybooru/thumbs/$1/$1$2
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^candybooru/(.*)$ /candybooru/index.php?q=$1&%{QUERY_STRING}
Maybe you could use this page to convert the rules: http://winginx.com/en/htaccess
The converted rule is:
# nginx configuration
location / {
rewrite "^/candybooru/_images/([0-9a-f]{2})([0-9a-f]{30}).*$" /candybooru/images/$1/$1$2;
rewrite "^/candybooru/_thumbs/([0-9a-f]{2})([0-9a-f]{30}).*$" /candybooru/thumbs/$1/$1$2;
}
location /candybooru {
rewrite ^/candybooru/(.*)$ /candybooru/index.php?q=$1&$query_string;
}
Check out try_files. I haven't tested this, but it should work (or come close):
location /candybooru/ {
location ~ "^/candybooru/_(images|thumbs)/([0-9a-f]{2})([0-9a-f]{30})" {
try_files /candybooru/$1/$2/$2$3 /candybooru/index.php?q=$2&$query_string;
}
}

Nginx rewrite equivalent of apache rewrite

I am trying to change the configuration on my new Nginx server so it matches my current Apache settings.
At the moment I am using this htaccess file:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*) index.php?url=$1 [L,QSA]
I have found a converter that could "translate" this into the Nginx equivalent. I have tried the following:
location / {
if (!-e $request_filename){
rewrite ^/(.*) /index.php?url=$1 break;
}
try_files $uri $uri/ =404;
}
But when I try to set a url query like this http://domain.tld/something my php file gets returned and downloaded and that ain't supposed to happen.
What I expect to happen is when a url like http://domain.tld/something is entered it gets treated like http://domain.tld/index.php?url=something
Can someone tell me what I am doing wrong?
Unlike Apache, nginx doesn't come out-of-the-box ready to run PHP. You need to setup a handler to deal with php files, otherwise nginx will serve them up just like any regular file.
See: Nginx downloads php instead of running it
Also: review the NGINX documentation on using fast-cgi to run php.

Nginx, rewrite multiple subfolders

I try to move my server from Apache towards a Nginx based setting. However, I get into problems getting a part of my htaccess Apache magic to work in Nginx.
The .htaccess code I would like to transfer is:
RewriteRule ^([a-zA-Z0-9_]+)/$ /index.php?page=$1 [L,QSA]
RewriteRule ^([a-zA-Z0-9_]+).html$ /index.php?page=$1 [L,QSA]
RewriteRule ^([a-zA-Z0-9_]+)/([0-9]+)/.*/([a-zA-Z0-9_]+)$ /index.php?page=$1&id=$2&sub=$3 [L,QSA]
RewriteRule ^([a-zA-Z0-9_]+)/([0-9]+)/.*$ /index.php?page=$1&id=$2 [L,QSA]
I used an online converter that gave me the following location block:
location / {
rewrite ^/([a-zA-Z0-9_]+)/$ /index.php?page=$1 break;
rewrite ^/([a-zA-Z0-9_]+).html$ /index.php?page=$1 break;
rewrite ^/([a-zA-Z0-9_]+)/([0-9]+)/.*/([a-zA-Z0-9_]+)$ /index.php?page=$1&id=$2&sub=$3 break;
rewrite ^/([a-zA-Z0-9_]+)/([0-9]+)/.*$ /index.php?page=$1&id=$2 break;
}
Sadly, I'm only able to get a single location rewrite to be working at a time (the one I put "last;" behind). I don't seem to be able to do this dynamic rewriting of a multiple subfolder URL into arguments for a single PHP script.
Any help on this? What is the Nginx way of doing such a rewrite? I tried using several location's for different subfolders but I would rather have a generic solution that work no-matter what url's are thrown at it.
Use a different location block for each rule:
location ~ ^/[a-zA-Z0-9_]+/$ {
rewrite ^/([a-zA-Z0-9_]+)/$ /index.php?page=$1 last;
}
location ~ ^/[a-zA-Z0-9_]+.html$ {
rewrite ^/([a-zA-Z0-9_]+).html$ /index.php?page=$1 last;
}
location ~ ^/[a-zA-Z0-9_]+/[0-9]+/.*/[a-zA-Z0-9_]+$ {
rewrite ^/([a-zA-Z0-9_]+)/([0-9]+)/.*/([a-zA-Z0-9_]+)$ /index.php?page=$1&id=$2&sub=$3 last;
}
location ~ ^/[a-zA-Z0-9_]+/[0-9]+/.*$ {
rewrite ^/([a-zA-Z0-9_]+)/([0-9]+)/.*$ /index.php?page=$1&id=$2 last;
}
location = /index.php {
# your proxy rules here...
}
The rewrite rules above use the last option, which is explained in the nginx docs:
last
stops processing the current set of ngx_http_rewrite_module
directives and starts a search for a new location matching the
changed URI;
