您选择了新数据库，然后在表上运行一些sql更新和替换命令，尤其是wp\\u options、wp\\u posts、wp\\u postmeta。

UPDATE wp_options SET option_value = replace(option_value, \'https://livesite.com\', \'http://localhost/sitename\') WHERE option_name = \'home\' OR option_name = \'siteurl\';

UPDATE wp_posts SET guid = replace(guid, \'https://livesite.com\',\'http://localhost/sitename\');

UPDATE wp_posts SET post_content = replace(post_content, \'https://livesite.com\', \'http://localhost/sitename\');

UPDATE wp_postmeta SET meta_value = replace(meta_value, \'https://livesite.com\', \'http://localhost/sitename\');
