My nginx config looks like this

server {
        listen       80;
        server_name  localhost;

        location / {
           root /var/www;
           index index.php index.html;
           autoindex on; 
        }

        location /folder1 {
           root   /var/www/folder1;
           index  index.php index.html index.htm;
           try_files $uri $uri/ index.php?$query_string;
        }

        location /folder2 {
           root   /var/www/folder2;
           index  index.php index.html index.htm;
        }

        location ~ \.php$ {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            include        fastcgi_params;
            fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}

The problem with the above setup is that i am not able to execute php files. Now as per my understanding of nginx config rules, when i am in my webroot(/) which is /var/www the value of $document_root becomes /var/www so when i request for localhost/hi.php the fastcgi_param SCRIPT_FILENAME becomes /var/www/hi.php and that is the actual path of the php script. But when i actully go to the url localhost/hi.php i get a message File not found. But when I go to the url localhost/hi.html i can see the html output of the page. So this means that there is a problem with the location block of php.

Similarly when i request for localhost/folder1/hi.php the $document_root becomes /var/www/folder1 because this is specified as the root in folder's location block so again the fastcgi_param SCRIPT_FILENAME becomes /var/www/folder1/hi.php. But when i actully go to the url localhost/folder1/hi.php i get a message File not found. But when I go to the url localhost/folder1/hi.html i can see the html output of the page. So again php are not being executed.

Please help?

I have been trying to get lithium running with Nginx with no success. The directory structure of lithium is like this

lithium
  |-> app libraries .htaccess
      |-> webroot .htacess --other directories
           |-> index.php .htaccess --other files

I copied the lithium folder into my /var/www/. The path of lithium is /var/www/lithium/

Now I set up the rewrite rules this way in my nginx.conf

server {
        listen       80;
        server_name  localhost;
        root /var/www/;

    location /lithium {
       rewrite ^/$ /app/webroot/ break;
       rewrite ^(.*)$ /app/webroot/$1 break;
    }

    location /lithium/app {
       rewrite ^/$ /webroot/ break;
       rewrite ^(.*)$ /webroot/$1 break;
     }

    location /lithium/app/webroot {
       if (!-e $request_filename){
        rewrite ^(.*)$ /index.php?url=$1 break;
        }
     }
 ...then my php and other configurations

But nginx always throws a 404 error. Why is that happening?

I also tried this

server {
            listen       80;
            server_name  localhost;
            root /var/www/;

location /lithium {
        if (!-e $request_filename) {
            rewrite ^/lithium/(.+)$ /lithium/app/webroot/$1 last;
            break;
            }
        }

        location /lithium/app/webroot {
        if (!-e $request_filename) {
            rewrite ^/lithium/app/webroot/(.+)$ /lithium/app/webroot/index.php?url=$1 last;
            break;
        }
    }
...then my php and other configurations

But again there is a 404 error.

Edit

As suggested i changed my server's root to /var/www/lithium/app/webroot so my nginx conf looks like this

server {
        listen   80;
        server_name localhost;

        root   /var/www/lithium/app/webroot;
        access_log /var/log/lithium/access.log;
        error_log /var/log/lithium/error.log warn;

        index  index.php index.html;

        try_files $uri $uri/ /index.php?$args;

        location ~ \.php$
        {
          .. ...
           ......

}

now i can see lithium's home but when i go to lithium's test dashboard which is http://localhost/test it again shows lithium's home instead of the test dashboard.When i use apache and go to url http://localhost/test it shows me the test dashboard. So the nginx rewrite rules are still not completely correct.More if i point root to lithium's webroot i cannot access other directories in my /var/www/

EDITED AGIAN

This is my complete server block

server { 
    server_name  lithium;
    root   /var/www/lithium/app/webroot;
    access_log  /var/log/nginx/lith.access.log;
    error_log   /var/log/nginx/lith.error.log;

    listen       127.0.0.2:80;
    rewrite_log on;

    # rewrite rules for lithium
    location / {
            index  index.php index.html;

            try_files $uri $uri/ /index.php?url=$uri&$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;
            fastcgi_param SERVER_NAME $host;
    }

    location ~ /\.ht {
            deny  all;
    }
}

I am using php 5.4.3. as php-fpm. I tried doing whats mentioned at lithium's official site here but i dont get this line

cp -f sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

which location is sapi referring to? Any ideas?

i had a project in which i had to redirect all not found files to the index.php. I did this in apache with placing a .htaccess file in my project folder. the file's contents are--

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [L]

now i wanted the same in nginx. here is how my nginx.conf looks like

root   /usr/local/apache2/htdocs;
index  index.php index.html index.htm;
location /project/ {
            root   /usr/local/apache2/htdocs;
            index  index.php index.html index.htm;
            try_files $uri $uri/ index.php;
}

now whenever i make a request like http://localhost/project/hello then this request should go to http://localhost/project/index.php but this says File not found.

Now why i thought this would work is because since the root directive inside the location block overrides the root directive outside the block (though there values are same), the rewrite module would look for /usr/local/apache2/htdocs/project/index.php. What am i missing here?

UPDATE

This configuration works

root   /usr/local/apache2/htdocs;
location /project/ {
            index  index.php index.html index.htm;    #effectively root here is /usr/local/apache2/htdocs
            try_files $uri $uri/ /project/index.php;
 }

But i dont see why this should work because as pointed out in the docs here directory matched in the location block is appended to the value of root directive

I installed php 5.3.8 from source on Ubuntu 10.10 and now i need mcrypt. I also installed mcrypt from source and restarted apache but still i am not able to see it in my php configuration. I understand i would need a mcrypt.so in my php extensions directory. I have installed a lot of extensions and like xdebug and apc and dont want to go through the pain of installing them again. Now how can i install mcrypt without re-installing php and passing mcrypt as a parameter to configure?

i tried elgg 1.8.0.1 on windows XP and it installed successfully but when i tried on fedora 12 it is not able to install. here is what happens i extracted the zip file for elgg 1.8.0.1 in /var/www/html now when i use firefox to go to the url http://localhost/elgg-1.8.0.1 it asks me whether i want to open or save install.php ,but when i open it with a text editor or if i save it and then open it its an empty file. The size of file is 0 bytes. And when i use Konqueror to do the above it displays a timeout error instantly(at the moment i press enter).

i checked the error log of apache and it displays the following line

child pid 2147 exit signal Segmentation Fault(11)

I was able to install elgg 1.7.11 on fedora successfully,also i am able to run other php files nicely.I wonder what can go wrong *because elgg 1.8.0.1 installs successfully in windows XP. (Note:I have the appropriate permissions for reading writing and executing scripts in the elgg 1.8.0.1 directory)

UPDATE: i tried strace php install.php and i got a long trace of which i am only showing the last few lines

mmap2(NULL, 11905, PROT_READ, MAP_SHARED, 3, 0) = 0xb77cb000
munmap(0xb77cb000, 11905)               = 0

time(NULL)                              = 1317422887

access("/var/www/html/elgg-1.8.0.1/engine/settings.php", R_OK) = -1 ENOENT (No such file or directory)
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV (core dumped) +++
Segmentation fault (core dumped)

Now any idea why there is this segmentation fault? I have read that infinite recursive function calls can cause seg faults but if that was the problem it wouldnt have run on windows. If i try to include a lot of files with include or require or require_once can it lead to php causing a segmentation fault?
