people i must produce a second site within the same webserver which i curently have my first site. i,m unsure how i'm able to do that, i wouldn't enjoy having to alter all of the url which i have previously produced. i believed on setting up another joomla within the folder where's the first. the url is going to be www.myweb1.com/joomla2, that's something which i wouldn't like it is possible to way by my dns will be able to change that www.myweb1.com/joomla2, to www.joomla2.com

Among the finest to produce a new joomla site within the same webserver which i curently have one joomla site. I,m using apache2 with opensuse. the very first site curently have a vhost to handle https rewrite conditions.

Any recomendation.

You should use the proxy functionality of Apache HTTPD.

Such configuration might seem like:

<VirtualHost *>
ServerName www.joomla2.com

ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>

ProxyPass / http://www.myweb1.com/joomla2
ProxyPassReverse / http://www.myweb1.com/joomla2
<Location />
Order allow,deny
Allow from all
</Location>
</VirtualHost>
