htaccess redirect from www to non-www

问题

I am new to this.

Code from my .htaccess file goes like this:

RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L] 

RewriteCond %{HTTP_HOST} ^www\.(.+) [NC]
RewriteRule ^(.*) http://%1/$1 [R=301,NE,L]

Redirect 301 /abc/ /abcnew/

I want this to redirect from www to non-www i.e., from http://www.example.com to http://example.com

I copied:

RewriteCond %{HTTP_HOST} ^www\.(.+) [NC]
RewriteRule ^(.*) http://%1/$1 [R=301,NE,L]

this code from here Generic htaccess redirect www to non-www.

I also checked in /etc/apache2/mods-enabled folder on my linux server. There "rewrite.load" this module is present.(I think this might mean that rewrite is enabled on my server, but correct me if I am wrong.)

Redirect 301 /abc/ /abcnew/

and just FYI this above code works fine(its redirecting my old links to new links).

I also tried this.

RewriteCond %{HTTP_HOST} ^www\.example\.com [NC]
RewriteRule ^(.*)$ http://example.com/$1 [L,R=301]

Doesn't work for me.

Please help. Thanks in advance...

Edit:

this link I found this. But not sure what should be edited. Can anyone please point out.?

You need to place external (full) redirect rules before internal rewrite ones and also make sure to use mod_rewrite rules only.

Try this:

RewriteEngine on
RewriteBase /

RewriteCond %{HTTP_HOST} ^www\.(.+) [NC]
RewriteRule ^(.*) http://%1/$1 [R=301,NE,L]

RewriteRule ^abc/?$ /abcnew/ [L,NC,R=301]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]
