I have the following URLs:
1) http://example.com/downloads/
2) http://example.com/downloads/widgets
3) http://example.com/downloads/gadgets
These URLs need to be redirected rewritten to the following:
1) http://example.com/products/
2 & 3 & etc) http://example.com/products/thingies
I'm currently trying the following nginx code:
location ~* ^/downloads/ {
rewrite ^/downloads/$ /products break;
rewrite ^/downloads/(.*)$ /products/thingies break;
}
It's almost working, however my site's document root is /var/www/example.com/public. So after processing the rewrite rules, nginx tries to literally serve /var/www/example.com/public/products/, whereas I want it to just rewrite to http://example.com/products/ (which then proxies to PHP and so on).
Where am I failing? Is there a different, better way to accomplish this?
Thank you for any help.
-- UPDATE --
I got it to work by using the following rules:
rewrite ^/downloads/?$ $scheme://$host/tools last;
location ~* ^/downloads/ {
rewrite ^/downloads/?$ $scheme://$host/products last;
rewrite ^/downloads/(.*)$ $scheme://$host/products/thingies last;
}
IS this the proper way of doing it in nginx? I haven't seen this rewrite rule format anywhere while researching this. It somehow seems odd.
Your update redirects, not rewrites.
Here is how I would do:
location /downloads/ {
rewrite ^ /products/thingies;
}
location = /downloads/ {
rewrite ^ /products/;
}
# uncomment if you need '/downloads' (without trailing slash) act as '/downloads/'
#location = /downloads {
# rewrite ^ /products/;
#}
The correct syntax appears to be:
location ~* ^/downloads/ {
rewrite ^/downloads/?$ /products permanent;
rewrite ^/downloads/(.*)$ /products/thingies permanent;
}

I'm trying to rewrite :
http://example/test/ -> http://example/new/
http://example/test/check -> http://example/new/check
location ~/test/(.*)$ {
rewrite ^/new/$1?$args permanent;
}
What am I doing wrong?
Your rewrite statement is incorrect. See this document for more.
To use rewrite to capture the latter part of the URI, try:
rewrite ^/test/(.*)$ /new/$1 permanent;
Alternatively, to use location to capture the latter part of the URI, try:
location ~ ^/test/(.*)$ {
return 301 /new/$1?$args;
}
I have a nginx rewrite rule like this
location ~* /question\-(.*)\.html$ {
rewrite "^/question-([0-9]+).html$" "/question/$1.html";
rewrite "^/question-([0-9]+).html$" /question.php?id=$1&lm=&pn= break;
}
This rule mean is:
if URI is /question-123456.html so rewrite to /question/123456.html
/question/123456.html is static file, and via question.php to create.
So when I visit http://example.com/question-123456.html HTTP rewrite to http://example.com/question/123456.html if not exist, I want to execute next rewrite rewrite "^/question-([0-9]+).html$" /question.php?id=$1&lm=&pn= break;
Other than return 404 to user.
I would write it this way:
location ~ /question-(.*)\.html$ {
try_files /question/$1.html /question.php?id=$1;
}
I'm using Nginx 1.6.2. I read that if () is evil and it's not good using it so I need a bit help, because I can't do what I want without using if(). I will post the rules I have with if and would ask if somebody could help me and tell me how to not use if () and use something else and get the same result.
# REDIRECT NON-WWW TO WWW.
if ($http_host != "www.site.eu") {
rewrite ^ http://www.site.eu$request_uri permanent;
}
# REMOVE INDEX FILES FROM URL FOR SEO PURPOSE.
if ($request_uri ~ "/index.php") {
rewrite ^ /$1 permanent;
}
# REMOVE ANY MULTIPLE SLASHES IN THE URL.
if ($request_uri ~* "\/\/") {
rewrite ^/(.*) $scheme://$host/$1 permanent;
}
First rule should be replaced with separate server blocks
server {
listen 80 default_server;
return 301 http://www.example.com$request_uri;
}
server {
listen 80;
server_name www.example.com;
# normal config
}
Other ifs usually are not necessary. Just don't generate links with index.php and you will not need to strip it.
In the official wiki introduction it says that there are some cases which are ok. Have a look at this quote:
The only 100% safe things which may be done inside if in location
context are:
return ...; rewrite ... last;
At the end of the introduction there is an example which also features a rewrite command. So your code looks ok, too.
EDIT: You should also have a look at how the if works.
You can replace this block
# REMOVE INDEX FILES FROM URL FOR SEO PURPOSE.
if ($request_uri ~ "/index.php") {
rewrite ^ /$1 permanent;
}
with this
location ~ ^/index.php/(.*[^/])$ { return 301 $scheme://$host/$1/$is_args$args; }
location ~ ^/index.php/(.*)/$ { return 301 $scheme://$host/$1/$is_args$args; }
I also don't think you need to worry about the last rule for double // because nginx by default automatically takes care of that before it even gets to the point of matching location blocks
I'm having a problem with my rewrite rule. It doesn't include folders in the rewrite path. For example:
/randomstring/app.js rewrites to /var/www/CDN/Dev/App/app.js
/randomstring/dashboard/app.js rewrites to /var/www/CDN/Dev/App/app.js but it should rewrite to /var/www/CDN/Dev/App/dashboard/app.js
I don't understand why it doesn't work. (.*) matches everything but a dot if I'm not mistaken so why doesn't it include the dashboard/ part?
location ~* (css|js)$ {
rewrite ^/([^/]*)/(.*).(css|js)$ /$2.$3 ;
root /var/www/CDN/Dev/App;
}
I see no reason to use rewrite here. Alias should be enough
location ~* /[^/]+(/.+\.(css|js))$ {
alias /var/www/CDN/Dev/App/$1;
}
location ~* \.(css|js)$ {
rewrite ^/([^/]+)/(.+)\.(css|js)$ /$2.$3 ;
root /var/www/CDN/Dev/App;
}
I'm completely new to nginx and I was wondering if someone could give me a hand.
What I'm trying to to is turn this:
domain.com/ngu/short.php?t=123
into
domain.com/t/123
If someone could explain to me how it's done, I would be very grateful. I have looked around the site for a similar situation, but I haven't found anything exactly the same so I'm having some difficulty. Thank you for your time :).
the following location block does the rewrite:
location ~ /ngu/short.php {
if ($args_t) {
rewrite ^ http://$host/t/$v? last;
}
}
but that requires you enumerate all possible arguments, if you have lots of potential arguments it's probably easier to do
location ~ /ngu/short.php {
if ($args ~ "([a-z]+)=(\d+)") {
set $p $1;
set $v $2;
rewrite ^ http://$host/$p/$v? last;
}
}
explanation:
we do a location that matches on the /ngu/short.php path
the first code block above checks if we have a t=value argument and if so does the rewrite
the second code block above checks for a more general argument=something. We then need to save the backreferences in variables because a rewrite rule resets the backreferences which prevents using them directly
in either case if the if fails to match a 404 will be returned
$host and $args en $args_ are standard nginx variables see http://wiki.nginx.org/HttpCoreModule#Variables
we add a ? ad the end of the rewrite to keep nginx from readding the url arguments
In case this helps anyone else, this is what I (actually a friend) ended up doing:
location / {
root /home/jim/www;
index index.html index.htm index.php;
if (!-f $request_filename) {
rewrite ^/t/(.+)$ /ngu/short.php?t=$1 last;
rewrite ^/u/(.+)$ /ngu/short.php?u=$1 last;
rewrite ^/s/ /ngu/short.php last;
break;
}
}
I don't understand it, but it works.
