Question

Can you help me? I have two servers with all permissions in CentOS, assigned IPs, and a subdomain that pointing to one, where there a static website. But, the other server has a blog on WordPress. The question is how pointing from a folder to another server. Thus:

subdomain.domain.com >> IP: 1.2.3.4
subdomain.domain.com/blog >> ANOTHER: 2.3.4.5

Answer 1

Your best bet is to use something like mod_proxy to reverse proxy requests for blog related resources to your WordPress Server.

So something like:

<VirtualHost *:80>
ServerName subdomain.domain.com
DocumentRoot /whatever
ProxyRequests Off

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

ProxyPass /blog http://2.3.4.5/blog
ProxyPassReverse /blog http://2.3.4.5/blog

#...

</VirtualHost>

One more point to mention, in the example above I reverse proxying to a resource identified by the hosts IP address. I would strongly recommend using a hostname and DNS instead since DNS is a good thing:

ProxyPass /blog http://blog.domain.com/blog
ProxyPassReverse /blog http://blog.domain.com/blog

Obviously you”l need to add 2.3.4.5 to DNS (or host hack accordingly)
