WordPress站点如何更换域名？ WordPress网站搬家整站迁移教程

一、进入数据库

以宝塔面板为例，在“对应数据库-管理”，用phpMyAdmin进入数据库。

二、执行SQL语句

在phpMyAdmin数据库管理面板找到SQL，然后执行下面的SQL语句

<span class="hljs-keyword"><span class="pln">UPDATE</span></span><span class="pln"> wp_options </span><span class="hljs-keyword"><span class="pln">SET</span></span><span class="pln"> option_value </span><span class="pun">=</span> <span class="hljs-keyword"><span class="pln">replace</span></span><span class="pun">(</span><span class="pln">option_value</span><span class="pun">,</span><span class="hljs-string"><span class="str">'旧域名'</span></span><span class="pun">,</span><span class="hljs-string"><span class="str">'ixxx.com'</span></span><span class="pun">);</span>

UPDATE wp_options SET option_value = replace(option_value,'旧域名','ixxx.com');
UPDATE wp_posts SET post_content = replace(post_content,'旧域名','xxx0.com');
UPDATE wp_posts SET post_excerpt= replace(post_excerpt,'旧域名','xxx.com');
UPDATE wp_comments SET comment_author_url = replace(comment_author_url,'旧域名','xxxcom');
UPDATE wp_postmeta SET meta_value = replace(meta_value,'旧域名','ixxx.com');

把语句中的“旧域名”替换成之前的域名，“idxxxx.com”替换为更换后的域名。

确认无误后点击右下角的执行按钮。

总结

这种方法步骤少，而且操作也是非常简单。执行5段SQL语句即可将数据库中配置、文章内容、文章摘要、评论者URL地址、自定义字段中的旧域名全部更换为新域名了。
