如何强制将所有 404(或每个页面，无论是否无效)重定向到主页?

问题描述

目前每个无效页面都是 500(内部服务器错误)，因为我可能搞砸了我的服务器块配置.

Currently every invalid page is 500 (Internal Server Error) because I probably messed up with my server block configuration.

不久前我决定关闭我的网站并创建了一个简单的单页感谢主页.然而，旧链接和外部站点仍在尝试访问该站点的其他部分，这些部分不再存在.

I decided to shut down my website a while ago and created a simple one-page, thank-you homepage. However old links and external sites are still trying to access other parts of the site, which no longer exists.

如何强制将所有非主页(任何无效 URL)重定向到主页?

How do I force redirect all non-homepage (any invalid URL) to the homepage?

我尝试了以下块，但没有奏效:

I tried with the following block, but it didn't work:

location / {
    try_files $uri $uri/ $document_uri/index.html;
}

我当前的配置是(我现在甚至不提供 PHP 文件，即主页是简单的 html):

My current configuration is (I don't even serve PHP files right now, ie homepage is simple html):

server {
    server_name www.example.com example.com;
    access_log /srv/www/example.com/logs/access.log;
    error_log /srv/www/example.com/logs/error.log;
    root /srv/www/example.com/public_html;
    index index.php index.html;

    location / {
        try_files $uri $uri/ $document_uri/index.html;
    }

    # Disable favicon.ico logging
    location = /favicon.ico {
        log_not_found off;
        access_log off;
    }

    # Allow robots and disable logging
    location = /robots.txt {
        allow all;
        log_not_found off;
        access_log off;
    }

    # Enable permalink structures
    if (!-e $request_filename) {
        rewrite . /index.php last;
    }

    # Handle php requests
    location ~ .php$ {
        try_files $uri = 404;
        include /etc/nginx/fastcgi_params;
        fastcgi_pass  127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_send_timeout 900;
        fastcgi_read_timeout 900;
        fastcgi_connect_timeout 900;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    # Disable static content logging and set cache time to max
    location ~* .(jpg|jpeg|gif|png|css|js|ico|xml)$ {
        access_log off;
        log_not_found off;
        expires max;
    }

    # Deny access to htaccess and htpasswd files
    location ~ /.ht {
        deny  all;
    }

    # Deny access to hidden files (beginning with a period)
    location ~ /. {
        access_log off; log_not_found off; deny all;
    }
}

推荐答案

像这样设置错误页面到首页

Setting the error page to the home page like this

error_page 404 /index.html;

有个小问题，首页的状态码会是404 not found"，如果你想加载带有200 ok"状态码的首页，你应该这样做

has a small problem, the status code of the home page will be "404 not found", if you want to load the home page with a "200 ok" status code you should do it like this

error_page 404 =200 /index.html;

这会将404 not found"错误代码转换为200 ok"代码，并加载主页

This will convert the "404 not found" error code to a "200 ok" code, and load the home page

@jvperrin 提到的第二种方法也不错，

The second method which @jvperrin mentioned is good too,

try_files $uri $uri/ /index.html;

但您需要记住一件事，因为它是 location/ 任何与另一个位置不匹配且未找到的资产也将加载 index.html，例如缺少图像、css、js 文件，但在您的情况下，我可以看到您已经有另一个与资产扩展名匹配的位置，因此您不应该遇到这个问题.

but you need to keep 1 thing in mind, since it's the location / any asset that doesn't match another location and is not found will also load the index.html, for example missing images, css, js files, but in your case I can see you already have another location that's matching the assets' extensions, so you shouldn't face this problem.
