WordPress网站未连接到非www上的数据库

Question

I'm having an issue with my WordPress site where it's unable to connect to the database on the non-www domain. I'm trying to rewrite all non-www requests as www with the following rule, but it's had no effect:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

On my server, I currently have two .htaccess files–one in the root directory, which redirects the naked domain into a sub-directory that contains my website (see below), and another in this sub-directory, which rewrites some default WordPress URLs.

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP_HOST} ^(www.)?domain.com$
RewriteCond %{REQUEST_URI} !^/sub-directory/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /sub-directory/$1
RewriteCond %{HTTP_HOST} ^(www.)?domain.com$
RewriteRule ^(/)?$ sub-directory/index.php [L]
</IfModule>

For DNS, I have an A record that points @ to my server's IP address, and a CNAME that points www to @ .

My wp-config.php file includes the following condition for reading database credentials:

if($_SERVER['SERVER_NAME'] !== 'www.domain.com') {
  include(dirname(__FILE__) . '/wp-config-local.php');
  define('WP_LOCAL', true);
}else {
  // Production credentials
}

I understand that domain.com fails to connect to my database because its $_SERVER['SERVER_NAME'] becomes domain.com instead of www.domain.com , but instead of adding both in the credentials condition, I thought the .htaccess rewrite would get around this. I'm struggling to determine where exactly the issue is. Thanks in advance

Answer 1

The issue was that the non-www rule was executed after the sub-directory redirect. Once placed before, everything worked as expected.
