Anyone use CI with Nginx?

And if so, are you able to use CI without adding the query string after index.php to view your controller methods?

Looking all over the net, I see instructions on “how to get CodeIgniter to work with Nginx” but that isn’t my problem. CodeIgniter works if I add the query string.

I imagine this is the same problem as ExpressionEngine. I can’t figure out how to configure Nginx to deliver the proper PATH_INFO information.

I’m using Nginx with FastCGI if that helps. Just as with anything in the open source ecosystem, the more I Google and read the more I pick up. Unfortunately I don’t have the man hours to spend on this problem to figure it out all the way.

Other options are to live with the query string. Remove it using the Nginx rewrite module. Or just use Apache like every other sane individual. 😉

Hm, found this thread and apparently this guy did figure out how to remove the query string from the URL. I guess I just have a configuration problem then. Ugh.

Yeah, thanks. That is how I found the thread that I linked to in my second post. I suppose I should have mentioned that. 😉

I really hate configuring web servers. Actually, I think I hate administration in general. I spend more time screwing with servers than I do actually coding.

EDIT:

Something like the following should work (of course you may have to mod for your setup and replace CAPS with proper values - BTW, this was ripped from one of my vhost configs and my main nginx.conf file contains much more general server config):
```
server {
  listen PORT;
  server_name NAME;
  root ROOT;

  location / {
    index index.php;

    if (-e $request_filename) {
      break;
    }

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

  location ~ \.php$ {
    if (!-f $request_filename) {
      return 404;
    }

    fastcgi_pass  127.0.0.1:PORT;
    fastcgi_index index.php;

    include FASTCGI_PARAMS;
  }
}
```
Also, make sure the following is set in your fastcgi_params file or you will get no input file specified (other vars must be set too - but see the manual):
```
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME     $fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT   $document_root;
```
Nginx can seem a bit strange at first if you are coming from Apache, but once you get the hang of it you will be amazed at how easy and intuitive the config is. You can do things really simply that are a pain with Apache. Also, compared to Apache, your RAM consumption will decrease by about 30-40% right off the bat. In any case, you should always RTFM if you want to gain expertise.

I just wanted to update this thread for future peeps looking to do the same thing.

I did figure out how to use URL’s without either the query string or the index.php.

Here is a Slicehost thread where I asked the same there and figured out the issue.

Basically you need to make sure that SCRIPT_FILENAME points directly to your index.php file. The other link mentioned in this thread also seems correct. Not sure why it didn’t work for me until now though.

As both linked areas mentioned, you also need to make the following config.php change.
```
$config['uri_protocol']  = "REQUEST_URI";
```
Here is a basic snippet of my Nginx config file.
```
server {

  server_name domain.com;

    location  /   {
        fastcgi_pass   localhost:8888;
        fastcgi_param SCRIPT_FILENAME
        /home/manofsteel/ci/index.php;
        ...
      }

    location ~ \.(js|ico|gif|jpg|png|css)$ {
      root /home/manofsteel/ci;
      }
}
```

Here’s what I’ve found to work best:

server {
    listen       80;
    server_name  domain.tld <a href="http://www.domain.tld">http://www.domain.tld</a>;
    # redirect to remove www
    if ($host = 'www.domain.tld' ) {
        rewrite  ^/(.*)$  <a href="http://domain.tld$uri">http://domain.tld$uri</a>  permanent;
    }
    location / {
        root /var/www/codeigniter/domain.tld/;
        index index.php index.html;
        # file doesn't exist, let CI handle it
        if (!-f $request_filename) {
            rewrite ^(.*) /index.php?$1 last;
        }
    }
    location ~ \.php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        include /opt/nginx/conf/fastcgi_params;
        fastcgi_param SCRIPT_FILENAME /var/www/codeigniter/domain.tld/index.php;
     }
}

(Tested with Nginx 0.6.3, CodeIgniter 1.7.1)

Will these work with routes and query off? atm i have to use something like this:

location / {
index index.php;
root /path/to/domain.net/httpdocs;

 if (-f $request_filename) {
      expires 30d;
      break;
    }
if (!-e $request_filename) {
      rewrite . /index.php last;
    }

}

location ~ \.php$
{
fastcgi_pass 127.0.0.1:9001;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param  REQUEST_URI      $request_uri;
fastcgi_param SCRIPT_FILENAME /path/to/domain/httpdocs/index.php;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_script_name;
}

For some reason though it causes my other directories like /forums/ to give 404’s, any ideas?

I use the cache system on ci as well if that’s neded.

Hey all, this may be an old post - but it comes up quite high in the google search so I thought I might mention that some of what you guys are doing can now be handled natively by nginx. Pay attention to the location block.

server {
        root /home/deploy/public_html/project/public;

        access_log /log/access.log;
        error_log /log/error.log;

        # the try_files declaration looks for the actual file, and if !exist goes to your fallback.
        location / { try_files $uri $uri/ /index.php; }


        # this is just an external file for all of your fastcgi_params;
        include php;
        
}

Here is the nginx documentation of try_files - http://wiki.nginx.org/NginxHttpCoreModule#try_files

That is exactly the reason why we started CloudIgniter. It let’s developers get back to developing.

This didn’t work for me, but I wanted to use try_files and tested a few options. Here’s what I have so far…

server {
    listen   80;
    server_name  domain;

    location / {
        root /var/www/domain;
        index index.php;
        
        if (-f $request_filename) {
            expires max;
            break;
        }

        try_files /maintenance.html $uri $uri/ @codeigniter;
    }

    location @codeigniter {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_split_path_info ^(.+\.php)(.*)$;
        fastcgi_param SCRIPT_FILENAME /var/www/domain/index.php;
        include fastcgi_params;
        fastcgi_param QUERY_STRING $request_uri;
    }

    location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|xml)$ {
        access_log        off;
        expires           30d;
    }
}

The file /maintenance.html doesn’t usually exist, but if I want to bring the site down temporarily while I work on it, all I have to do is create maintenance.html in the web root and it will be displayed to users until it is removed.

I will go ahead and use the same excuse for posting here 😊

Now i wanted to do a proper config for codeigniter that did not use any Ifs whatsoever, because Ifs are evil, and worked using PATH_INFO to mix segmented URLs and querystrings.

These were made using CodeIgniter 2.0, and haven’t tested them using 1.7.2, but should work

server {
    server_name     _;
    index           index.html;
    root            /var/www/;

    location / {
        try_files $uri $uri/ @codeigniter;
    }
    #Restrict access to application and system folders
    #location /system { #For 1.7.2, uncomment this and comment below to use
    location /(application|system) { #2.0, uncomment this and comment above to use - remember to edit application to your apps folder if changed
        internal;
    }

    #Cache static content
    location ~* ^.+\.(jpg|jpeg|gif|css|png|js|ico|swf|wav)$ {
        expires max;
    }
    location @codeigniter {
        include /etc/nginx/fastcgi_params;
        fastcgi_pass   localhost:9000;
        fastcgi_index  index.php;

        fastcgi_split_path_info ^(/)(.*)$;
        fastcgi_param SCRIPT_FILENAME /var/www/index.php;
        fastcgi_param PATH_INFO $fastcgi_path_info;
        fastcgi_param DOCUMENT_ROOT /var/www/;
        fastcgi_param SERVER_NAME $http_host;
    }
}

I recently switched to nginx and here is how I setup my host -

I also kept the protocol to auto with out any issues.
