Need help with converting this htaccess to nginx rewrite

brianzimmer · February 13, 2009, 10:56pm

I'm really interested in utilizing Nginx on my Slicehost account, but my main holdout is understanding how to adjust .htaccess files so that my site can function properly on Nginx.

I've made an attempt, but I'm just not a regular expressions guy and am new to this part altogether. Unfortuantely, I'm having a difficult time moving over to Nginx rewrite rules. I'll post my attempt at the Nginx rewrite rules, but first I'm going to post the mod_rewrite rules of my Symphony CMS site, so we have the direct comparison. If anyone knows Nginx... your help is much appreciated!!!

Here's the regular mod_rewrite for the index.php in document root folder for Symphony...

Original Symphony 2 `.htaccess`

### DO NOT APPLY RULES WHEN REQUESTING "favicon.ico"
RewriteCond %{REQUEST_FILENAME} favicon.ico [NC]
RewriteRule .* - [S=14]

### IMAGE RULES
RewriteRule
^image\/3\/([0-9]+)\/([0-9]+)\/([1-9])\/([a-fA-f0-9]{3,6})(\/(0|1))?\/(.+)\.(jpg|gif|jpeg|png|bmp)$
/symphony/image.php?param=3:$1:$2:$3:$4:$6:$7.$8 [L]
RewriteRule
^image\/2\/([0-9]+)\/([0-9]+)\/([1-9])(\/(0|1))?\/(.+)\.(jpg|gif|jpeg|png|bmp)$
/symphony/image.php?param=2:$1:$2:$3:0:$5:$6.$7 [L]
RewriteRule
^image\/1\/([0-9]+)\/([0-9]+)(\/(0|1))?\/(.+)\.(jpg|gif|jpeg|png|bmp)$
/symphony/image.php?param=1:$1:$2:0:0:$4:$5.$6 [L]
RewriteRule ^image(\/(0|1))?\/(.+)\.(jpg|gif|jpeg|png|bmp)$
/symphony/image.php?param=0:0:0:0:0:$2:$3.$4 [L]

### CHECK FOR TRAILING SLASH - Will ignore files
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !/$
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ /$1/ [L,R=301]

### MAIN REWRITE - This will ignore directories
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)\/$ /index.php?page=$1&%{QUERY_STRING} [L]

My Nginx attempt

I don't think this is right, but would love to get some input.

location / {
    if ($request_filename="favicon.ico") {
        rewrite  ^(.*)$  break;
    }

    ### IMAGE RULES
    rewrite
^image\/3\/([0-9]+)\/([0-9]+)\/([1-9])\/([a-fA-f0-9]{3,6})(\/(0|1))?\/(.+)\.(jpg|gif|jpeg|png|bmp)$
/symphony/image.php?param=3:$1:$2:$3:$4:$6:$7.$8 last;
    rewrite
^image\/2\/([0-9]+)\/([0-9]+)\/([1-9])(\/(0|1))?\/(.+)\.(jpg|gif|jpeg|png|bmp)$
/symphony/image.php?param=2:$1:$2:$3:0:$5:$6.$7 last;
    rewrite
^image\/1\/([0-9]+)\/([0-9]+)(\/(0|1))?\/(.+)\.(jpg|gif|jpeg|png|bmp)$
/symphony/image.php?param=1:$1:$2:0:0:$4:$5.$6 last;
    rewrite ^image(\/(0|1))?\/(.+)\.(jpg|gif|jpeg|png|bmp)$
/symphony/image.php?param=0:0:0:0:0:$2:$3.$4 last;

    ### CHECK FOR TRAILING SLASH - Will ignore files
    if (!-f $request_filename) {
        rewrite ^/(.+)$ /$1/ permanent;
    }

    ### MAIN REWRITE - This will ignore directories
    if (!-d $request_filename) {
        rewrite ^/(.+)$ /index.php?url=$1 last;
    }
}

I think you’re pretty close.

Try

location / {
if ($request_filename ~ “favicon.ico$”) {
rewrite ^(.*)$ last;
}

### IMAGE RULES
rewrite

^/image/3/([0-9]+)/([0-9]+)/([1-9])/([a-fA-f0-9]{3,6})(/(0|1))?/(.+).(jpg|gif|jpeg|png|bmp)$
/symphony/image.php?param=3:$1:$2:$3:$4:$6:$7.$8 last;
rewrite
^/image/2/([0-9]+)/([0-9]+)/([1-9])(/(0|1))?/(.+).(jpg|gif|jpeg|png|bmp)$
/symphony/image.php?param=2:$1:$2:$3:0:$5:$6.$7 last;
rewrite
^/image/1/([0-9]+)/([0-9]+)(/(0|1))?/(.+).(jpg|gif|jpeg|png|bmp)$
/symphony/image.php?param=1:$1:$2:0:0:$4:$5.$6 last;
rewrite ^/image(/(0|1))?/(.+).(jpg|gif|jpeg|png|bmp)$
/symphony/image.php?param=0:0:0:0:0:$2:$3.$4 last;

### CHECK FOR TRAILING SLASH - Will ignore files
if (!-f $request_filename) {
    rewrite ^/(.+)$ /$1/ permanent;
}

### MAIN REWRITE - This will ignore directories
if (!-d $request_filename) {
    rewrite ^/(.+)$ /index.php?url=$1 last;
}

}

I’m not sure this will work but clearly you are missing some forward
slashes in the image rules. Good luck!

However, I do not understand what this part is intended for:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !/$
RewriteCond %{REQUEST_URI} !(.)/$
RewriteRule ^(.)$ /$1/ [L,R=301]

MAIN REWRITE - This will ignore directories

RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /index.php?page=$1&%{QUERY_STRING} [L]

Probably this may be served something else better than ugly:

 location / {
     if (!-d $request_filename) {
         rewrite ^/(.+)$ /index.php?url=$1 last;
 }

Jim and Igor -

Thank you both for your help and input. Unfortunately, I need to spend
more time in a local environment trying to learn how to get this up and
running.

I kept getting Server Errors (500) when even running phpinfo(); just to
test php. I couldn’t get it running ever.

NGINX is really impressive. It would be nice to have a “NGINX for
dummies” tutorial that goes step by step, even showing the basic setup
to get PHP up and running properly. I followed the “Perfect setup
tutorial”,
http://www.mensk.com/webmaster-toolbox/perfect-ubuntu-hardy-nginx-mysql5-php5-wordpress/.
As well as some in the English wiki. Everyone, I kept getting 500
errors. Or I’d get “no valid input” notification.

Again, I’m sure it’s something I’m doing. But if y’all know of the
simplest “NGINX for dummies” tutorial to get PHP working and basic
virtual host setup for PHP. That would be helpful.

Again, thank you both for your quick replies. It was very helpful!

I’d be interested in that. Thanks Jim for replying and for your help.
Also, Igor, thank you for your help!

Isnt that the same what the wiki (http://wiki.codemongers.com/Main) is
for?

brianzimmer · February 15, 2009, 7:29pm

No. A wiki is a wiki and a forum is a forum. They each have a place and
a
purpose.

See Wiki - Wikipedia and
Internet forum - Wikipedia.

Like I said, I’m more than happy to donate the space, bandwidth, and
vBulletin license if there’s enough interest.

People can contact me privately if they prefer.
