Convert .htaccess rules to nginx.conf - .htaccess

Question

Hello I am trying to covert the following .htaccess lines so that arrowchat can work in my nginx server. The location of my arrowchat folder is like this /usr/share/nginx/html/arrowchat/ where /usr/share/nginx/html/ is the root folder for my website. My VPS has only one website, www.jukpac.com hosted on it. Below is the .htaccess code
<IfModule mod_rewrite.c>
Options +FollowSymlinks
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^chatroom ^/../public/chatroom/ [L]
RewriteRule ^cron ^/../public/cron/ [L]
RewriteRule ^debug ^/../public/debug/ [L]
RewriteRule ^list ^/../public/list/ [L]
RewriteRule ^mobile ^/../public/mobile/ [L]
RewriteRule ^popout ^/../public/popout/ [L]
RewriteRule ^video ^/../public/video/ [L]
</IfModule>
<IfModule mod_headers.c>
<FilesMatch "\.(gif|jpg|png|css|swf)$">
Header add "Expires" "Mon, 28 Jul 2014 23:30:00 GMT"
Header add "Cache-Control" "max-age=31536000"
</FilesMatch>
</IfModule>
<IfModule mod_expires.c>
ExpiresActive On
ExpiresDefault A604800
ExpiresByType text/css A604800
ExpiresByType image/gif A604800
ExpiresByType image/png A604800
ExpiresByType image/jpeg A604800
ExpiresByType application/x-shockwave-flash A604800
</IfModule>
I tried a few online .htaccess converter but it didn't work can some one please let me know how to fix this?
My current default.conf file for nginx looks like this
#
# The default server
#
server {
listen 80;
server_name jukpac.com;
return 301 http://www.jukpac.com$request_uri;
}
server {
listen 80;
server_name www.jukpac.com;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root /usr/share/nginx/html;
index index.php index.html index.htm;
}
error_page 404 /404.html;
location = /404.html {
root /usr/share/nginx/html;
}
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}

Ok with the Help of a friend, in Serverfault I managed to get the correct configuration as shown below
server { #redirecting server
listen 80;
server_name jukpac.com;
return 301 http://www.jukpac.com$request_uri;
}
server {
listen 80;
server_name www.jukpac.com;
root /usr/share/nginx/html; #move the root to server level
index index.php # move index to server level
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location / {
try_files $uri $uri/ =404;
}
location ~* \.(?:ico|css|js|gif|jpe?g|png|swf)$ {
expires 30d;
add_header Pragma public;
add_header Cache-Control "public";
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
location ~ /\.ht {
deny all;
}
}
