编辑您网站根目录下面的.htaccess文件，将以下规则添加到文件末尾，如果没有该文件，请创建一个。
（说明： domain.com 就是你要做的域名网址，自己替换就行。）
1.重定向domain.com到www.domain.com
这种重定向旨在使域名唯一，是网站SEO必须要做的，后面重定向www.domain.com到domain.com也是出于同样的原因，只是形式不同。
打开.htaccess文件，加入以下规则。(下面的规则是针对主域名的，子域名要修改)
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www.domain.com$ [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [L,R=301]
RewriteCond %{HTTP_HOST} !^www.domain.com$ [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [L,R=301]
2.重定向www.domain.com到domain.com
RewriteEngine On
RewriteCond %{HTTP_HOST} !^domain.com$ [NC]
RewriteRule ^(.*)$ http://domain.com/$1 [L,R=301]
RewriteCond %{HTTP_HOST} !^domain.com$ [NC]
RewriteRule ^(.*)$ http://domain.com/$1 [L,R=301]
3.重定向olddomain.com到www.newdomain.com
RewriteEngine On
RewriteCond %{HTTP_HOST} !olddomain.com$ [NC]
RewriteRule ^(.*)$ https://www.seozhi.com/wp-content/uploads/$1 [L,R=301]
RewriteCond %{HTTP_HOST} !olddomain.com$ [NC]
RewriteRule ^(.*)$ https://www.seozhi.com/wp-content/uploads/$1 [L,R=301]
4.重定向olddomain.com to newdomain.com
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !olddomain.com$ [NC]
RewriteRule ^(.*)$ https://www.seozhi.com/wp-content/uploads/$1 [L,R=301]
RewriteBase /
RewriteCond %{HTTP_HOST} !olddomain.com$ [NC]
RewriteRule ^(.*)$ https://www.seozhi.com/wp-content/uploads/$1 [L,R=301]
5.重定向domain.com/file/file.php 到 otherdomain.com/otherfile/other.php
RewriteCond %{HTTP_HOST} ^www.domain.com$
RewriteRule ^file/file.php$ https://www.seozhi.com/wp-content/uploads/tdfs=1&s_token=1583460954.0034642875&uuid=1583460954 [R=301,L]
RewriteRule ^file/file.php$ https://www.seozhi.com/wp-content/uploads/tdfs=1&s_token=1583460954.0034642875&uuid=1583460954 [R=301,L]
