Introduction to Apache Two-level domain name implementation method _linux

Second, after opening the mod_rewrite in httpd.conf, at the end of httpd.conf, add the following:
Rewriteengine on
Rewritemap lowercase Int:tolower
Rewritemap Vhost Txt:/usr/local/etc/apache/vhost.map
Rewritecond ${lowercase:%{server_name}} ^ (. +) $
Rewritecond ${vhost:%1} ^ (/.*) $
Rewriterule ^/(. *) $%1/$1

The/usr/local/etc/apache is the path to your Apache server configuration file, which is changed according to the actual situation.

Then, create a file in the directory that contains the path: Vhost.map content is:
Www.domain.com/usr/local/www/data-dist/domain
Bbs.domain.com/usr/local/www/data-dist/bbs
Anyname.domain.com/usr/local/www/data-dist/anyname

The above parts are: "Domain name + space + absolute path" form.


Finally, under your site root directory/usr/local/www/data-dist, create the corresponding directory:
Domain, BBS, anyname and so on, theoretically can be unlimited.

In this way, through the browser, access to www.domain.com, the actual access is the/usr/local/www/data-dist/domain directory of files. Similarly, the access bbs.domain.com actually accesses the files in the/usr/local/www/data-dist/bbs directory. Also, you can change vhost.map at any time to add, remove, and modify your level two domain name and the actual path you point to, without restarting Apache.
