无法从IP访问nginx服务器

所以2天前，我可以看到那个页面，它说：“欢迎使用nginx”，但是到现在，当我试图访问它，它说404页面没有find…为什么这是？ 在我的网站启用文件夹我有一个名为默认的文件，它有以下内容：

# You may add here your # server { # ... # } # statements for each of your virtual hosts server { listen 80; server_name 127.0.0.1; access_log /var/log/nginx/localhost.access.log; location / { root /var/www/nginx-default; index index.html index.htm; } location /doc { root /usr/share; autoindex on; allow 127.0.0.1; deny all; } location /images { root /usr/share; autoindex on; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # #error_page 500 502 503 504 /50x.html; #location = /50x.html { # root /var/www/nginx-default; #} # 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$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/nginx-default$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; } } # another virtual host using mix of IP-, name-, and port-based configuration # #server { #listen 8000; #listen somename:8080; #server_name somename alias another.alias; #location / { #root html; #index index.html index.htm; #} #} # HTTPS server # #server { #listen 443; #server_name localhost; #ssl on; #ssl_certificate cert.pem; #ssl_certificate_key cert.key; #ssl_session_timeout 5m; #ssl_protocols SSLv2 SSLv3 TLSv1; #ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP; #ssl_prefer_server_ciphers on; #location / { #root html; #index index.html index.htm; #} #} 

这是我的nginx.conf文件：

 user www-data; worker_processes 4; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; events { worker_connections 1024; # multi_accept on; } http { include /etc/nginx/mime.types; access_log /var/log/nginx/access.log; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; tcp_nodelay on; gzip on; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } # mail { # # See sample authentication script at: # # http://wiki.nginx.org/NginxImapAuthenticateWithApachePhpScript # # # auth_http localhost/auth.php; # # pop3_capabilities "TOP" "USER"; # # imap_capabilities "IMAP4rev1" "UIDPLUS"; # # server { # listen localhost:110; # protocol pop3; # proxy on; # } # # server { # listen localhost:143; # protocol imap; # proxy on; # } # } 

我在这里做错了什么？ 我有其他的虚拟主机设置在网站启用以及…

更新：

• 麻烦nginx和从同一个域下的多个目录服务
• 在域名（不带端口号）上启动Tornado App
• 有了nginx，我怎么做所有www站点到非www站点的质量redirect
• nginx虚拟主机不工作，所有的虚拟主机都转到默认主机
• 将nginx限制在一个目录下

server_name指令是：-admin.api.frapi
-api.frapi
-默认
-example.com
-php.example.com

 server { # The default/fallback server must have 'default' in the listen line: listen 80 default; # Catch all non-matching requests server_name _; access_log /var/log/nginx/localhost.access.log; location / { root /var/www/nginx-default; index index.html index.htm; } #etc ... }
