wordpress更改域名之后无法访问的完美解决办法

wordpress又更换域名了，之前是在http://www.iisp.com/注册的.top域，现在打算全部换到name.com上的.com域名， 更改如下：

1. 从wordpress后台修改WordPress Address (URL)和Site Address (URL)
2. 修改菜单里的Login超链接
3. 修改数据库：
   
   UPDATE wp_options SET option_value = replace(option_value, 'rainyday.top','www.meaninglive.com'); UPDATE wp_posts SET post_content = replace(post_content, 'rainyday.top','www.meaninglive.com'); UPDATE wp_posts SET guid = replace(guid, 'http://rainyday.top', 'https://www.meaninglive.com' ); UPDATE wp_comments SET comment_content = replace(comment_content, 'rainyday.top', 'www.meaninglive.com'); UPDATE wp_comments SET comment_author_url = replace(comment_author_url, 'rainyday.top', 'www.meaninglive.com');

   UPDATE wp_options SET option_value = replace(option_value, 'rainyday.top','www.meaninglive.com'); UPDATE wp_posts SET post_content = replace(post_content, 'rainyday.top','www.meaninglive.com'); UPDATE wp_posts SET guid = replace(guid, 'http://rainyday.top', 'https://www.meaninglive.com' ); UPDATE wp_comments SET comment_content = replace(comment_content, 'rainyday.top', 'www.meaninglive.com'); UPDATE wp_comments SET comment_author_url = replace(comment_author_url, 'rainyday.top', 'www.meaninglive.com');

   
   rainyday.top为旧域名， www.meaninglive.com为新域名
