nginx second site configuration

Please help me!!!!!!!!! I am trying to setup a second site using nginx but looks like all requests are going to the same place. I mean to this site here "institutoprana.com.br"

If you type in www.agencialojavirtual.br it goes to www.institutoprana.com.br.

What can I do to make the appropriate requests to go correctly to each domain?

server {
listen 80;


root /var/www/prana;
index index.php index.html index.htm;

server_name institutoprana.com.br;

location / {
try_files $uri $uri/ /index.php?q=$uri&$args;
}

error_page 404 /404.html;

error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/www;
}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9$
location ~ \.php$ {
#fastcgi_pass 127.0.0.1:9000;
# With php5-fpm:
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
}

location /phpmyadmin {
root /usr/share/;
index index.php index.html index.htm;
location ~ ^/phpmyadmin/(.+\.php)$ {
try_files $uri =404;
root /usr/share/;
#fastcgi_pass 127.0.0.1:9000;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
#include /etc/nginx/fastcgi_params;
include fastcgi_params;
}
location ~* ^/phpmyadmin/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
root /usr/share/;
}
}
location /phpMyAdmin {
rewrite ^/* /phpmyadmin last;
}
}

server {
listen 80;
root /var/www/retiroaybrasilia;
index index.php index.html index.htm;
server_name agencialojavirtual.com.br;
location / {
try_files $uri $uri/ /index.php?q=$uri&$args;
}


Thank you
