Legacy! : This is a very old post transfered from my previous blog.  Information presented here may or may not be true! If there is interest  in the topic let me know so i'll update it :-)

I am often asked about proper rewrite rules for concrete 5 when using  nginx web server. I have found the rules below to be equivalent with  the default apache2 rewrite rules:

Inside an nginx site config file:

server {
listen 80;
server_name yoursitename.com
root /path/to/your/web/folder;
index index.php;
error_log /path/to/your/error.log;
location /{
try_files $uri $uri/ /index.php$request_uri;
}
location ~ .php($|/) {
set $script $uri;
if ($uri ~ “^(.+.php)(/.+)”) {
set $script $1;
}
fastcgi_split_path_info ^(.+.php)(/.+)$;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$script;
fastcgi_temp_file_write_size 10m;
fastcgi_busy_buffers_size 512k;
fastcgi_buffer_size 512k;
fastcgi_buffers 16 512k;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
fastcgi_intercept_errors on;
fastcgi_next_upstream error invalid_header timeout http_500;
fastcgi_pass 127.0.0.1:port or your fastcgi socket file
}
}

Please note that this is not meant to be a copy paste solution,  neither a perfect one. You should inspect and adjust the parameters  above to your paths and desired values. The above can be used both for  fastcgi and FPM.I suggest that you create a separate fpm pool for each website as  its more secure and less troublesome than running all your virtual hosts  as the same php user. Perhaps one day i will publish a step by step  guide to setup an nginx+php5-fpm multiuser + mysql webserver. Let me  know if you are interested.
