Can't access localhost?

Use is the native Ubuntu nginx do Web server, but the previous period of time has been good, suddenly can not connect localhost, check a lot of data also no solution.
The Nginx service is enabled as follows:

$ sudo service nginx status * nginx is running

/etc/nginx/nginx.confIs the default is not moved, one of which is include also, as follows:

### Virtual Host Configs##include /etc/nginx/conf.d/*.conf;include /etc/nginx/sites-enabled/*;

/etc/nginx/site-availableThe default in, as follows:

server {    listen 80 default_server;    listen [::]:80 default_server ipv6only=on;    root /usr/share/nginx/html;    index index.html index.htm;    server_name localhost;    location / {        # First attempt to serve request as file, then        # as directory, then fall back to displaying a 404.        try_files $uri $uri/ =404;        # Uncomment to enable naxsi on this location        # include /etc/nginx/naxsi.rules    }    location ~ \.php$ {        fastcgi_split_path_info ^(.+\.php)(/.+)$;        # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini        # With php5-cgi alone:        fastcgi_pass 127.0.0.1:9000;        # With php5-fpm:        # kfastcgi_pass unix:/var/run/php5-fpm.sock;        fastcgi_index index.php;        include fastcgi_params;    }    # deny access to .htaccess files, if Apache's document root    # concurs with nginx's one}

Then visit localhost as follows:

How is it solved?

127.0.0.1 also cannot access or open an agent.

Nginxubuntuunder the schema differs from centos or, the windows usual nginx all-site configuration is placed in the /etc/nginx/site-availabl directory, but note that this is only a usable configuration, if you want to open the configuration of the MO-site such as ( www.test.com ), you need to /etc/nginx/site-enabled create软连接

$ pwd/etc/nginx/site-enabled$ sudo ln -s /etc/nginx/site-availabl/www.test.com www.test.com

Soft connect created well after Chongqing NG ,

Find out if there's 127.0.0.1 locahost.
No, No.

# echo "127.0.0.1 locahost" >> /etc/hosts

Solved, but not quite understood;
I site-available default copied a copy of the file into/etc/nginx/conf.d/default.conf
And then

sudo nginx -tsudo service nginx restart

You can do it. Is it /etc/nginx/conf.d /etc/nginx/site-available OK to write the configuration file in any directory with them?

Is it a firewall setup problem?
