以 wordpress 作为子目录的 Nginx 在帖子中返回 404

Question

在Wordpress子目录下添加各种配置后，WP首页可以正常访问，但是还是进不了帖子，返回404。

www.test.com/blog - WP homepage, works perfectly fine

www.test.com/blog/test-post-for-blog - WP Post, 404

配置如下：

server {
  listen 80;
  listen [::]:80;

  server_name www.test.com;

  location ^~ /media {
    alias /var/local/test/static/media;
  }

  location ^~ /icons {
    alias /var/local/test/static/icons;
  }

  location /blog {
    alias /var/www/html;
    index  index.html index.htm index.php;
    try_files $uri $uri/ /blog/index.php?$args /blog/index.php?q=$uri&$args;
    # try_files $uri $uri/ /blog/index.php?q=$uri$args;

    location ~ \.php$ {
      try_files $uri =404;
      include fastcgi_params;
      fastcgi_intercept_errors on;
      fastcgi_index index.php;
      fastcgi_pass blog-test:9000;
      fastcgi_split_path_info ^(/blog)(/.*)$;
      fastcgi_param SCRIPT_FILENAME $request_filename;
      fastcgi_param PATH_INFO $fastcgi_path_info;
    }
  }
}

和日志：

2022/02/09 14:47:25 [error] 32#32: *45 open() "/etc/nginx/html/index.php" failed (2: No such file or directory), client: 10.10.10.10, server: www.test.com, request: "GET /blog/test-post-for-blog/ HTTP/1.1", host: "www.test.com", referrer: "https://www.test.com/blog/"

查看日志，好像查错了地方，就是/etc/nginx/html/index.php，但如果我在 php 位置块中添加别名，那么主页也会停止工作，这让我有点困惑。

目前不太确定是不是博客块中的alias问题（nginx建议不要同时使用alias try_files，显然是由于错误）或其他原因。如果确实是别名指令，我会尝试添加root，以及一些重写规则以避免修改文件结构。

我真的花了很多时间才弄明白，但仍然无法真正理解这里可能存在的问题。

更新 1：

这非常奇怪。使用以下博客配置，将 php 位置与博客分开，可以访问 WP 帖子，但不能访问主页和管理，返回 404:

  location /blog {
    alias /var/www/html;
    try_files $uri $uri/ /index.php?$args;
  }

  location ~ \.php$ {
    alias /var/www/html;
    try_files $uri =404;
    include fastcgi_params;
    fastcgi_intercept_errors on;
    fastcgi_index index.php;
    fastcgi_pass blog-test:9000;
    fastcgi_split_path_info ^(/blog)(/.*)$;
    fastcgi_param SCRIPT_FILENAME $request_filename;
    fastcgi_param PATH_INFO $fastcgi_path_info;
  }

更新 2：

现在可以使用了（可以访问博客和帖子），但管理员似乎进入了重定向循环：

  location /blog {
    alias /var/www/html;
    index index.php;
    try_files $uri $uri/ /blog/index.php?q=$uri&$args;
  }

  location ~ \.php$ {
    alias /var/www/html;
    try_files $uri $uri/ /index.php?$args;
    include fastcgi_params;
    fastcgi_intercept_errors on;
    fastcgi_index index.php;
    fastcgi_pass blog-test:9000;
    fastcgi_param SCRIPT_FILENAME $request_filename;
  }

更新 3 和修复：

这显然有效，但配置似乎真的很不愉快且未优化。如果我尝试将 php 位置嵌套到博客块中，那么 php 文件将下载而不是呈现。如果我尝试使用别名而不是 root，某些页面将不会显示，导致 404。无论如何，这似乎是有效的：

  root /var/www/html; 
  index index.php;

  location /blog {
    rewrite ^/blog(.*)$ / break;
    try_files $uri $uri/ /blog/index.php?$args;
  }
          
  location ~ \.php$ {
    rewrite ^/blog(.*)$  break;
    fastcgi_pass blog-test:9000;
    fastcgi_index index.php;
    include fastcgi_params;
    fastcgi_split_path_info ^(/blog)(/.*)$;
    fastcgi_param SCRIPT_FILENAME $request_filename;
    fastcgi_param PATH_INFO $fastcgi_path_info;
  }

Answer 1

在 /blog 目录之外，您可能还有 php 个文件。应该有一个单独的块用于具有相同设置的 wordpress 安装，但是用于博客目录。

这可能是 wordpress 的块（在 Docker 中测试）

  location /blog {
    try_files $uri $uri/ /blog/index.php?$args;
    
    location ~ \.php$ {
      fastcgi_split_path_info ^/blog/(.+\.php)(/.+)$;
      fastcgi_pass wp:9000;
      fastcgi_index index.php;
      include fastcgi_params;
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
      fastcgi_param SCRIPT_NAME $fastcgi_script_name;
    }
  }

所以你完整的 nginx 配置应该是这样的：

server {
  listen 80;
  listen [::]:80;

  server_name www.test.com;
  root /var/www/html; 
  index index.php; 

  location ^~ /media {
    alias /var/local/test/static/media;
  }

  location ^~ /icons {
    alias /var/local/test/static/icons;
  }

  # This is for Wordpress
  location /blog {
    try_files $uri $uri/ /blog/index.php?$args;
    
    location ~ \.php$ {
      fastcgi_split_path_info ^/blog/(.+\.php)(/.+)$;
      fastcgi_pass wp:9000;
      fastcgi_index index.php;
      include fastcgi_params;
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
      fastcgi_param SCRIPT_NAME $fastcgi_script_name;
    }
  }

  # This is for php files in the root. If there is no php to be parsed there you could leave these blocks out.
  location / {
    try_files $uri $uri/ /index.php?$args;
  }
  
  location ~ \.php$ {
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass wp:9000;
    fastcgi_index index.php;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param SCRIPT_NAME $fastcgi_script_name;
  }
}

更新：我在 nginx 服务器配置中添加了 root 和 index 属性。
