Ubuntu top-level domain names direct to second-level domain names

The www.a.com website is OK and a.com is required to be opened.

I checked some information and modified the. htaccess file. However, for efficiency, we decided to use the 301 permanent jump method.

First, create the text file a.com in the/etc/apach2/sites-available Directory (which can be any name) as follows:

<Virtualhost *: 80> servername A. comredirectmatch permanent ^/(. *) http://www.a.com/#1 </virtualhost>

Run

A2ensite a.com/etc/init.d/apache2 reload

It should be said that it is OK, but the test fails, but no problem is found?

No matter how it works. Restart Apache to check whether it is executed.

/Etc/init. d/apache2 restart

This test is OK. Why? It's not very clear. It's probably the difference between restart and reload. Ubuntu version: 10.04

The above is for your reference!
