Múltiplos Domínios Nome em um servidor com Nginx

Question

Estou com dificuldades para configurar dois nomes de domínios diferentes no meu servidor dedicado ...

Eu já tenho um DN configurado assim no vhost DOMAIN_1.net.conf:

server {
listen 127.0.0.1:8080;

    server_name DOMAIN_1.net;
    access_log /home/DOMAIN_1/logs/access.log;
    error_log /home/DOMAIN_1/logs/error.log;
    root /home/DOMAIN_1;

    client_max_body_size 30M;

    location / {
        index  index.php index.html index.htm;
        if (!-e $request_filename) {
                rewrite . /index.php last;
        }

    }

        location ~ \.php$ {
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
                fastcgi_pass unix:/var/run/php5-fpm.sock;
                include /etc/nginx/fastcgi_params;
        }
}

Eu também tenho três outros subdomínios desse domínio configurados da mesma maneira.

E eu quero instalar um servidor owncloud no nome de domínio DOMAIN_2.ovh no vhost DOMAIN_2.ovh.conf:

upstream php-handler {
        server 127.0.0.1:9000;
        #server unix:/var/run/php5-fpm.sock;
}

server {
        listen 8080;
        server_name DOMAIN_2.ovh;
        return 301 https://$server_name$request_uri;  # enforce https
}

server {
        listen 8080;
        #listen 443 ssl;
        server_name DOMAIN_2.ovh;

        #ssl_certificate /etc/nginx/certs/owncloud.crt;
        #ssl_certificate_key /etc/nginx/certs/owncloud.key;

        error_log /home/DOMAIN_2.ovh/logs/error.log;
        access_log /home/DOMAIN_2.ovh/logs.access.log;

        # Path to the root of your installation
        #root /var/www/;
        root /home/DOMAIN_2.ovh/www/;

        client_max_body_size 10G; # set max upload size
        fastcgi_buffers 64 4K;

        rewrite ^/caldav(.*)$ /remote.php/caldav$1 redirect;
        rewrite ^/carddav(.*)$ /remote.php/carddav$1 redirect;
        rewrite ^/webdav(.*)$ /remote.php/webdav$1 redirect;

        index index.php;
        error_page 403 /core/templates/403.php;
        error_page 404 /core/templates/404.php;

        location = /robots.txt {
            allow all;
            log_not_found off;
            access_log off;
        }

        location ~ ^/(?:\.htaccess|data|config|db_structure\.xml|README) {
                deny all;
        }

        location / {
                # The following 2 rules are only needed with webfinger
                rewrite ^/.well-known/host-meta /public.php?service=host-meta last;
                rewrite ^/.well-known/host-meta.json /public.php?service=host-meta-json last;

                rewrite ^/.well-known/carddav /remote.php/carddav/ redirect;
                rewrite ^/.well-known/caldav /remote.php/caldav/ redirect;

                rewrite ^(/core/doc/[^\/]+/)$ $1/index.html;

                try_files $uri $uri/ index.php;
        }

        location ~ \.php(?:$|/) {
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
                include fastcgi_params;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                fastcgi_param PATH_INFO $fastcgi_path_info;
        #        fastcgi_param HTTPS on;
                fastcgi_pass php-handler;
        }

        # Optional: set long EXPIRES header on static assets
        location ~* \.(?:jpg|jpeg|gif|bmp|ico|png|css|js|swf)$ {
                expires 30d;
                # Optional: Don't log access to assets
                access_log off;
        }

}

Mas quando eu reinicio o Nginx, recebo este erro:

nginx: [avisar] nome do servidor conflitante "DOMAIN_2.ovh" em 0.0.0.0:8080, ignorado nginx.

Meu arquivo nginx.conf:

user www-data;
worker_processes 4;
pid /var/run/nginx.pid;

events {
        worker_connections 768;
        # multi_accept on;
}

http {

        ##
        # Basic Settings
        ##

        sendfile on;
        tcp_nopush on;
        tcp_nodelay on;
        keepalive_timeout 65;
        types_hash_max_size 2048;
        server_tokens off;

        # server_names_hash_bucket_size 64;
        # server_name_in_redirect off;

        include /etc/nginx/mime.types;
        default_type application/octet-stream;

        ##
        # Logging Settings
        ##

        access_log /var/log/nginx/access.log;
        error_log /var/log/nginx/error.log;

        ##
        # Gzip Settings
        ##

        gzip on;
        gzip_disable "msie6";

        ##
        # Virtual Host Configs
        ##

        include /etc/nginx/conf.d/*.conf;
        include /etc/nginx/sites-enabled/*;
}

Eu encontrei muitos assuntos sobre esse erro, mas não consegui resolver ... Se alguém puder me ajudar, será um ótimo presente de natal;) oh oh oh
