How to change domain name in wordpress

Whether it is a personal website or a corporate website, generally we do not recommend changing the domain name of the website, because this will not only affect the ranking of the website in search engine results, It reduces website traffic and also leaves a bad impression among website users. However, in some cases, we also have to change domain names. For example, we purchased a more suitable domain name; or we forgot to renew the previous domain name and had to change it to a new domain name; or we used a temporary domain name during the website registration period and switched to our own domain name after registration; or we built a website for a customer and the test was completed Then switch to the official domain name and so on.

Let’s take the demo website at hand as an example to introduce how to change the domain name of the WordPress website from the old domain name www.mydomain.com to the new domain name www.newdomain.com .

The first step, before starting, please back up the website, website database and website files. Especially the database must be backed up to prevent errors during the operation. We can use the backed up database to re-operate.

The second step is to resolve and bind the new domain name. Resolving a new domain name means pointing the domain name to the IP address of the server, usually at the domain name provider; binding the new domain name, usually at the space provider, means adding the new domain name on the server and ensuring that the website directory and the old domain name are The website directory is consistent.

After completing the above two steps, you need to confirm that the new domain name is effective before continuing with the following operations. After the new domain name is set for resolution, it usually takes a while to be transmitted to the local network. The effective time is not consistent in different places. It usually takes a few minutes or a few hours, and it will not exceed 48 hours at most. You can use the ping command to check to see if the new domain name is effective. If the IP address pinged is the IP just set, then the resolution will take effect.

After the new domain name takes effect, you can open the original website by entering the new domain name and the old domain name in the browser at this time. If the old domain name is no longer valid, for example, has expired, or has been resolved to another place, etc., then although the website can be opened, the web page will look messy; this is because the web page cannot load the WordPress theme style sheet normally.

The third step is to log in to the host management system, enter phpmyadmin, and select the database used by the WordPress website. If you are not sure which database WordPress is using, you can check the wp-config.php configuration file in the WordPress directory to see the DB_NAME setting.

After selecting the database, click SQL and enter the following code:

UPDATE wp_options SET option_value = replace(option_value, 'www.mydomain.com','www.newdomain.com') ;
UPDATE wp_posts SET post_content = replace(post_content, 'www.mydomain.com','www.newdomain.com') ;
UPDATE wp_comments SET comment_content = replace(comment_content, 'www.mydomain.com', 'www.newdomain.com') ;
UPDATE wp_comments SET comment_author_url = replace(comment_author_url, 'www.mydomain.com', 'www.newdomain.com') ;

In the above code, www.mydomain.com represents the original domain name, and www.newdomain.com represents the new domain name. The domain name must be entered completely; if you use a second-level domain name like blog.newdomain.com, it is also ok, just enter the complete domain name.

Modify the WordPress website domain name in phpmyadmin

Then click the [Execute] button in the lower right corner, and that’s it. phpmyadmin will return the results and tell you how many places were modified in each line of command. In this way, we have perfectly switched the WordPress domain name to the new domain name.

Compared with modifying the domain name directly in the WordPress management background, the method introduced today has two advantages:

1. Even if the old domain name has expired, you can still change it to a new domain name; because During the entire operation, there is no need to log in to the WordPress management backend.

2. The replacement is relatively complete. Not only the domain name of the website has been changed, but also the links within the article, the addresses and links of media files such as pictures, audio and video, and links in comments, etc. have also been changed.

Therefore, through the above operations, you can perfectly change the WordPress website domain name. Now, try using the new domain name to access your WordPress website. Are there any problems?
