WordPress站点.htaccess配置：主页映射至main子目录，其余页面保留根目录

Got it, let's work through this .htaccess setup to get exactly what you need: serving your new /main WordPress homepage at example.com (no URL redirect) while keeping all other pages like example.com/about-us pointing to your root WordPress site.

Step 1: Update Root .htaccess #

First, replace or modify your root directory's .htaccess file with these rules. This will prioritize the new homepage forward while letting all other requests fall back to your existing root site:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

# Serve the new homepage from /main (internal rewrite, no URL change)
RewriteRule ^$ /main/ [L]

# Default WordPress rules for all other requests (uses root site)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

Step 2: Fix WordPress Configuration in /main #

To make sure your new /main WordPress site loads resources (CSS, JS, images) correctly without pointing to /main in URLs, add these lines to your /main/wp-config.php file (right before the line that says /* That's all, stop editing! Happy publishing. */):

define('WP_HOME','https://example.com');
define('WP_SITEURL','https://example.com/main');

This tells the /main WordPress installation that its public-facing URL is the root domain, even though its core files live in the subdirectory.

Step 3: Test and Verify #

• Visit example.com: You should see your new /main homepage, with the URL still showing example.com (no redirect to /main).
• Visit example.com/about-us (or any other existing page): You should land on your original root WordPress site's page.
• Check the new homepage's source code to ensure all asset links (CSS, JS) point to https://example.com/wp-content/... instead of including /main (the wp-config.php changes take care of this).

Key Notes #

• Make sure your server has mod_rewrite enabled (most Apache hosts have this on by default, but if not, you may need to contact your host or enable it via cPanel).
• If you have existing custom rules in your root .htaccess, merge these carefully—keep the homepage rewrite rule above the default WordPress index.php rule.
