Nginx download problem css / images

Question

I configured NGINX and now it works with php and html files. But it cannot load images, * .js and * .css files. Here are my configuration files for NGINX.

This is my nginx.conf file

user nginx; worker_processes 1; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; keepalive_timeout 65; #gzip on; include /etc/nginx/conf.d/*.conf; } 

Here is the default.conf file, which can be located at /etc/nginx/conf.d

  server { listen 80; server_name localhost; #charset koi8-r; #access_log /var/log/nginx/log/host.access.log main; location / { root /home/username/www; index index.php index.html index.htm; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root /home/username/www; } # proxy the PHP s to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # proxy_pass http://127.0.0.1; #} ## Images and static content is treated different location ~* ^.+\.(jpg|jpeg|gif|css|png|js|ico|xml)$ { access_log off; expires max; root /home/username/www; } # pass the PHP s to FastCGI server listening on 127.0.0.1:9000 # location ~ \.php$ { fastcgi_split_path_info ^(.+\.php)(.*)$; fastcgi_pass backend; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /home/username/www$fastcgi_script_name; include fastcgi_params; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_intercept_errors on; fastcgi_ignore_client_abort off; fastcgi_connect_timeout 60; fastcgi_send_timeout 180; fastcgi_read_timeout 180; fastcgi_buffer_size 128k; fastcgi_buffers 4 256k; fastcgi_busy_buffers_size 256k; fastcgi_temp_file_write_size 256k; } # deny access to .htaccess files, if Apache document root # concurs with nginx one # location ~ /\.ht { deny all; } } upstream backend { server 127.0.0.1:9000; }
