nginx默认根在端口80上返回404

尝试通过端口80上的IP访问我的服务器时遇到问题。

如果我去IP我得到nginx 404错误页面。

这是我的默认configuration看起来像：

# You may add here your # server { # ... # } # statements for each of your virtual hosts to this file server { listen 80; ## listen for ipv4; this line is default and implied #listen [::]:80 default ipv6only=on; ## listen for ipv6 # Document root root /var/www/default; index index.html index.htm; # Make site accessible from http://localhost/ server_name localhost; location / { # First attempt to serve request as file, then # as directory, then fall back to index.html try_files $uri $uri/ /index.html; # Uncomment to enable naxsi on this location # include /etc/nginx/naxsi.rules } location /doc/ { alias /usr/share/doc/; autoindex on; allow 127.0.0.1; deny all; } # Only for nginx-naxsi : process denied requests #location /RequestDenied { # For example, return an error code #return 418; #} #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # #error_page 500 502 503 504 /50x.html; #location = /50x.html { # root /usr/share/nginx/www; #} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # #location ~ \.php$ { # 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: # fastcgi_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 # #location ~ /\.ht { # deny all; #} } 

在/var/www/default里面有一个名为index.html的文件。 现在到怪异的部分。 如果我把监听端口改为8888 nginx会正确地提供index.html。 我只有3个网站，其他的是虚拟主机，所以他们没有听指令。 我已经将/var/www/default文件夹设置为chmod 777 ，但仍然在端口80上返回404 。

• Nginx：路由到特定path组件的别名内的index.php
• 覆盖nginx拒绝单个位置块的规则
• 如何使其他nginx服务器前面的nginx反向代理caching失效？
• NGINX – 仅影响Firefox的CORS错误

编辑：我检查了nginx的错误日志，这是说： 2014/04/08 09:30:21 [error] 3349#0: *1 "/etc/nginx/html/index.html" is not found

然后问题是，这个configuration在哪里说/etc/nginx/html/index.html是默认的根？

 listen 80 default_server;
