将Wordpress数据库更新到新域

Posted 2021-02-25

If you've got a Wordpress install that's changed domain or you're making a local or development copy, you'll need to update the Wordpress DB tables with the new URL. The first step is the options table, with siteurl and homeurl. The posts also store the URL, but if the main options are correct WP will figure it out, though I update them too just in case.

-- change wp_ to your database's table prefix
-- change oldurl, newurl
-- oldurl is the one in the database already
-- newurl might be your localhost or development address
 
UPDATE wp_options SET option_value = REPLACE (option_value, 'http://oldurl','http://newurl');
 
UPDATE wp_posts SET guid = REPLACE (guid,'http://orldurl','http://newurl');
