Nginx with worpress as sub-directory returning 404 in posts-CodePudding

After adding various configurations into the Wordpress subdirectory, I can access without any issues the WP homepage, but I'm still not able to access the posts, returning 404.

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

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

Here is the config:

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;
    }
  }
}

And the log:

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/"
10.10.10.10 - admin [09/Feb/2022:14:47:25  0000] "GET /blog/test-post-for-blog/ HTTP/1.1" 404 187 "https://www.test.com/blog/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.87 Safari/537.36"

Checking the logs, it seems to look into the wrong place, which is /etc/nginx/html/index.php, but if I add the alias in the php location block, then the homepage will stop working as well, which gets me a bit confused.

Currently, I'm not quite sure if the problem is the alias in the blog block ( nginx recommends not using alias together with try_files, apparently due to a bug ), or anything else. If it is indeed the alias directive, I'll try to add root, together with some rewrite rules to avoid modifying the file structure.

It really took me more than it should to figure it out, and still can not actually understand what might be the issue here.

UPDATE:

This is extremely odd. With the following blog config, separating the php location from the blog, the WP posts are accesible, but not the homepage and admin, returning 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;
  }

CodePudding user response：

Outside the /blog dir you might also have php files. There should be a separate block for the wordpress install that has the same settings, but then for the blog dir.

This could be the block for wordpress (tested in Docker)

  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;
    }
  }

So your complete nginx config would look like this:

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;
  }

  # 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;
  }
}
