WordPress is an open source content management system (CMS) for creating and managing websites. It started out as a blog publishing system, but over time has evolved into a powerful platform that can be used to build all types of websites, including personal blogs, commercial websites, online stores, news sites, portfolios, forums, and more. In the process of using WordPress, sometimes you may need to change the domain name, but many friends do not know exactly how it should be done. I today for you to detail the domain name replacement method!

Before you start replacing your domain name, you need to prepare for the following steps:

1. Purchase a new domain name: First, a suitable new domain name needs to be chosen and purchased.
2. Setting up Domain Jumps: After the purchase of a new domain name, in order to allow users who visit the old domain name to automatically transfer to your new domain name, you need to set up a domain name jump (redirection) function at the domain name service provider.
3. Backup Sites: Before officially changing your domain name, it is highly recommended that you backup your WordPress site. In this way, in case any accidents happen during the replacement process, you can quickly restore to the previous state and avoid data loss.

WordPress Steps to Change Domain Name:

1,Modify WordPress Configuration File::

First, log in to the WordPress admin backend. Then, find the file namedwp-config.phpfile (usually this file is located in the root of the WordPress installation directory). Next, open the file using a text editor (e.g. Notepad, Sublime Text, etc.) and find the specific code inside to modify.

define('WP_SITEURL', 'http://' . $_SERVER['HTTP_HOST'] . '/');
define('WP_HOME', 'http://' . $_SERVER['HTTP_HOST'] . '/');

Place the http://和/替换为新的域名 in it:

define('WP_SITEURL', 'https://www.newdomain.com');
define('WP_HOME', 'https://www.newdomain.com');

take note of: If the site is using the HTTPS protocol, set http://替换为https://.

2. Update the website address in the database:

You need to log in to your MySQL database management tool (e.g. phpMyAdmin). From there, find your WordPress database (it may be calledwordpressOr one that starts withwp_(the name at the beginning). Next, open thewp_optionstable and find the fields in this table that contain the site address. These fields typically include things like "Site URL" and "Home Page".

siteurl: option to store the website address, https://www.olddomain.com, replacing it with the new domain name, https://www.newdomain.com.

home: option to store the address of the home page, https://www.olddomain.com/, replacing it with the new domain name, https://www.newdomain.com/.

3,Updated fixed link settings:

Log in to the backend of your WordPress site, find the Settings > Fixed Links page and click "Save Changesbutton, at this time the system will detect the new domain name, and automatically update the fixed link structure, if not automatically updated, you can try to manually select "plain URL" or "article name URL" and other link structure, and then click "Save Changes". Then click "Save Changes".

4,Check if the new domain name is active::

After completing the above steps, try visiting your new domain name and see if the website displays properly. If you encounter any problems, such as page loading errors or abnormal display, you can check the error message given by your browser.

5. Update search engines and external links:

Once you've changed your domain name, don't forget to tell the search engines (e.g. Baidu, Google, etc.) your new website address so they can update the inclusion information. Also, don't forget to update links elsewhere, such as those left in friendship links, forum signatures, etc., to make sure they point to the new domain name.

6. Delete the old domain name resolution:

After confirming that the new domain name can be accessed normally, you need to delete the old domain name resolution records. This will prevent users from being redirected to the new domain name when accessing through the old domain name. The specific operation method may vary depending on the domain name registrar and resolution service used, please follow the corresponding guidelines.
