使用的是本机 ubuntu nginx做web服务器，奈何前段时间一直好好的，突然就无法连接localhost了，查了很多资料也无解。
nginx服务处于开启状态如下:

$ sudo service nginx status * nginx is running

/etc/nginx/nginx.conf是默认的没有动过, 其中的include也对，如下:

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

/etc/nginx/site-available中的default，如下:

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 }

然后访问localhost就如下:

请问是如何解决呢

127.0.0.1也无法访问， 也没有开代理。

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

$ cat /etc/hosts

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

sudo nginx -t sudo service nginx restart
