如何在Nginx中设置自定义503错误页面，拦截所有请求？

我学会了如何让NGINX返回503客户错误页面，但我找不到如何执行以下操作：
配置文件示例：

location / {
        root   www;
        index  index.php;
        try_files /503.html =503;
    }

    error_page 503 /503.html;
    location = /503.html {
        root   www;
    }

正如您所看到的，根据上面的代码，如果在我的根目录中找到一个名为503.html的页面，站点将把这个页面返回给用户。

但是虽然上面的代码在有人访问我的网站时可以正常工作

使用我的代码，用户仍然可以看到配置文件页面或除index.php之外的任何其他页面。
问题是：
当503.html出现在我的根文件夹中时，如何捕获对站点中所有页面的请求并将其转发到503.html？

nginx

下面的配置适用于接近最新稳定的nginx 1.2.4。我找不到一种方法来启用维护页面与使用if，但显然根据IfIsEvil，这是一个确定的if。

要启用维护touch /srv/sites/blah/public/maintenance.enable。您可以rm要禁用的文件。
错误502将被Map到503，这是大多数人想要的，你不想给予谷歌一个502。
自定义502和503页面。你的应用将生成其他错误页面。

网上还有其他配置，但它们似乎在最新的nginx上不起作用。

server {
    listen       80;
    server_name blah.com;

    access_log  /srv/sites/blah/logs/access.log;
    error_log  /srv/sites/blah/logs/error.log;

    root   /srv/sites/blah/public/;
    index  index.html;

    location / {
        if (-f $document_root/maintenance.enable) {
            return 503;
        }
        try_files /override.html @tomcat;
    }

    location = /502.html {
    }

    location @maintenance {
       rewrite ^(.*)$ /maintenance.html break;
    }

    error_page 503 @maintenance;
    error_page 502 =503 /502.html;

    location @tomcat {
         client_max_body_size 50M;

         proxy_set_header  X-Real-IP  $remote_addr;
         proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_set_header  Host $http_host;
         proxy_set_header  Referer $http_referer;
         proxy_set_header  X-Forwarded-Proto http;
         proxy_pass http://tomcat;
         proxy_redirect off;
    }
}

更新日期：将“if -f”更改为“try_files”。

试试这个：

server {
    listen      80;
    server_name mysite.com;
    root    /var/www/mysite.com/;

    location / {
        try_files /maintenance.html $uri $uri/ @maintenance;

        # When maintenance ends, just mv maintenance.html from $root
        ... # the rest of your config goes here
     }

    location @maintenance {
      return 503;
    }

}

其他的答案都是正确的，但是要补充的是，如果您使用内部代理，您还需要在其中一个代理服务器上添加proxy_intercept_errors on;。
比如说...

proxy_intercept_errors on;
    root /var/www/site.com/public;
    error_page 503 @503;
    location @503 {
       rewrite ^(.*)$ /scripts/503.html break;
    }

多年以后，我现在使用的是完全自定义的错误消息。
HTML错误页存储在网站根目录下的/http-error目录中。
