WordPress固定链接URL重定向及自建站点配置与域名变更问题咨询

Hey there! Let's break down your two questions step by step—they're both super common when migrating from WordPress.com to a self-hosted setup, so I’ve got you covered.

First, let’s cover the most likely scenario: you’re setting up a self-hosted WordPress site (since you mentioned a PHP environment, which WordPress runs on). If you’re building a custom PHP site instead, I’ve included that too.

If You’re Using Self-Hosted WordPress #

• Log into your WordPress admin dashboard.
• Navigate to Settings → Permalinks.
• WordPress.com’s default permalink structure is the Day and name option, which looks like https://yourdomain.com/2024/05/20/your-post-title/. Just select that radio button and click Save Changes.
• If you used a custom structure on WordPress.com (like just the post name: https://yourdomain.com/your-post-title/), choose the Post name option or paste your exact custom structure into the Custom Structure field (e.g., /%postname%/).
• Pro tip: WordPress will usually update your .htaccess file automatically. If it can’t, you’ll see a code snippet on the Permalinks page—copy that and paste it into your site’s root .htaccess file to make the permalinks work.

If You’re Building a Custom PHP Site #

If you’re not using WordPress, you’ll need to set up URL rewriting via your server config. For Apache (the most common server for PHP sites), edit or create a .htaccess file in your site’s root:

• To mimic WordPress.com’s Day and name structure (/year/month/day/post-name/), add these rules:

RewriteEngine On
RewriteBase /
RewriteRule ^([0-9]{4})/([0-9]{2})/([0-9]{2})/([^/]+)/?$ index.php?year=$1&month=$2&day=$3&post=$4 [L,QSA]

• To mimic the Post name structure (/post-name/), use:

RewriteEngine On
RewriteBase /
RewriteRule ^([^/]+)/?$ index.php?post=$1 [L,QSA]

• You’ll then need to update your PHP code to read the query parameters (year, month, day, post) and load the correct content.

Yes, you can absolutely redirect exact URLs like www.olddomain.com/aze/123 to www.newdomain.com/aze/123. Permanent 301 redirects are best here—they preserve your SEO and tell browsers/search engines the content has moved permanently.

Option 1: Apache Server (Using .htaccess) #

Add these lines to your old site’s .htaccess file (or the new site’s if you’ve already migrated the content):

RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.olddomain.com$ [NC]
RewriteRule ^(.*)$ https://www.newdomain.com/$1 [R=301,L]

• The (.*) captures everything after the old domain, and $1 inserts that exact path into the new URL. If you don’t use www, adjust the RewriteCond to ^olddomain.com$ and the new URL to https://newdomain.com/$1.

Option 2: Nginx Server #

If your server runs Nginx, add this to your server block for the old domain:

server {
    listen 80;
    listen [::]:80;
    server_name www.olddomain.com olddomain.com;
    return 301 https://www.newdomain.com$request_uri;
}

• The $request_uri variable grabs the full path and query string, so every exact URL gets redirected perfectly.

Option 3: WordPress Plugin (For Self-Hosted WP) #

If you’re using self-hosted WordPress, you can use a plugin like Redirection to set up precise redirects. This is handy if you need to handle individual URL exceptions, but server-level redirects (above) are more efficient for full domain migrations.
