//enable mod rewrite urls. 0=disabled, 1=enabled for SEO Friendly URLS
$Gbl["ManualModRewrite"] = 1;

The original rewrite rule (Apache) for the script are as follows :

RewriteEngine On
#PAGES
RewriteRule ^([^/]*)/$ index.php?p=$1 [L]
# CATEGORY
RewriteRule ^([^/]*)/([^/]*)/$ index.php?p=$1&i=$2 [L]
# CATEGORY PAGES
RewriteRule ^([^/]*)/([^/]*)/([^/]*)/$ index.php?p=$1&i=$2&pg=$3 [L]

You have to add your custom rewrite rule to nginx base on the Apache rewrite rule above. But don’t worry because I already do that for you. All you have to do is open your nginx.conf file or your virtual host configuration and add the following rule to the section location /.

if (!-e $request_filename){
                rewrite ^/([^/]*)/$ /index.php?p=$1 last;
                rewrite ^/([^/]*)/([^/]*)/$ /index.php?p=$1&i=$2 last;
                rewrite ^/([^/]*)/([^/]*)/([^/]*)/$ /index.php?p=$1&i=$2&pg=$3 last;
        }

Once added, save the configuration file and close your text editor. Now restart nginx with the following command.

/etc/init.d/nginx restart

Congratulation you have clean url on your OSWallpaper script now.

nano /etc/nginx/nginx.conf

But if you set up a virtual host, you should open the virtual host configuration for the host where you install wordpress. If you are using Debian, the configuration files is located at /etc/nginx/sites-available/. The following command should do that.

nano /etc/nginx/sites-available/example.com

Now find the section location / . Add the following code inside the curly brackets {}.

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

Below is virtual host sample configuration after adding the code above.

server {
    listen       80;
    server_name  example.com;

    error_log   logs/error-example.log;
    access_log  logs/access-example.log;

    location / {
        root   /var/www/example.com;
        index  index.html index.htm index.php;

        #error_page 404 = /index.php?q=$request_uri;
         if (!-e $request_filename) {
                rewrite ^/(.*)$ /index.php?q=$1 last;
                break; }
    }
    location ~ .php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_param SCRIPT_FILENAME /var/www/example.com$fastcgi_script_name;
        fastcgi_index index.php;
        include /usr/local/nginx/conf/fastcgi_params;
    }

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

Now save the file and close the text editor. The changes will not take effect until you restart nginx. It’s totally different from Apache where you can edit .htaccess and don’t need to restart Apache in order to apply the change. So run the following command the restart nginx.

/etc/init.d/nginx restart

Now you can log in to your wordpress blog and customize your permalinks to your liking.

Below is the rewrite rule in the .htaccess for Apache :

Options +FollowSymlinks

RewriteEngine On
RewriteRule ^category/([0-9A-Za-z\+\_\-]+)/$ /categories.php?Category=$1 [nc]
RewriteRule ^category/([0-9A-Za-z\+\_\-]+)/([0-9]+)/$ /categories.php?Category=$1&page=$2 [nc]
RewriteRule ^wallpaper/([0-9A-Za-z\_\-]+)/$ /details.php?Title=$1 [nc]
RewriteRule ^images/wmwallpapers/(.+)$ /watermark.php?k=$1 [nc]

To apply the same rewrite rules to nginx. Paste the following rule to your nginx.conf or in your nginx virtual host configuration file.

if (!-e $request_filename) {
rewrite ^/category/([0-9A-Za-z\+\_\-]+)/$ /categories.php?Category=$1 last;
rewrite ^/category/([0-9A-Za-z\+\_\-]+)/([0-9]+)/$ /categories.php?Category=$1&page=$2 last;
rewrite ^/wallpaper/([0-9A-Za-z\_\-]+)/$ /details.php?Title=$1 last;
rewrite ^/images/wmwallpapers/(.+)$ /watermark.php?k=$1 last;
}

You should put it inside the location / {} section. Below is my virtual host configuration file after applying the rewrite rule.

server {
listen       80;
server_name  wallpapers.com;

error_log   logs/error-wallpapers.log;
access_log  logs/access-wallpapers.log;

location / {
root   /var/www/wallpapers.com;
index  index.html index.htm index.php;

if (!-e $request_filename) {
rewrite ^/category/([0-9A-Za-z\+\_\-]+)/$ /categories.php?Category=$1 last;
rewrite ^/category/([0-9A-Za-z\+\_\-]+)/([0-9]+)/$ /categories.php?Category=$1&page=$2 last;
rewrite ^/wallpaper/([0-9A-Za-z\_\-]+)/$ /details.php?Title=$1 last;
rewrite ^/images/wmwallpapers/(.+)$ /watermark.php?k=$1 last;
}
}

location ~ .php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME /var/www/wallpapers.com$fastcgi_script_name;
fastcgi_index index.php;
include /usr/local/nginx/conf/fastcgi_params;
}

# redirect server error pages to the static page /50x.html
#
error_page   500 502 503 504  /50x.html;
location = /50x.html {
root   html;
}

location ~ /\.ht {
deny all;

Congratulation, you will now have a Wallpaper Site Creator script work on nginx web server. If you need any help or want to add any suggestion please do not hesitate to leave your comments.
