How to forward a domain to a Vagrant VM with Apache on OSX
January 27, 2015
I do a lot of my development work using Virtual Machines and Vagrant. This provides an easy way for me to get a working environment up and running locally on the many projects I work on daily. However, one of the problems with this is that these VMs aren't accessible externally. This can be a problem when you need to show your work or use a third party service that needs access to the site.
I've solved this problem by using a dynamic domain name service together with Apache's mod_proxy. Essentially the domain name points to my Macbook and Apache forwards the traffic to the Vagrant VM.
Here's how it is done. Imagine I have a dynamic domain name of
andrew.dyn.dns.com pointing at my macbook, and a website
devsite.andrew.dyn.dns.com running on the Vagrant VM (with the IP address 192.168.56.10). Apache2 is installed on the Macbook (by default).
/etc/apache2/http.conf and uncomment the following line:
LoadModule proxy_module libexec/apache2/mod_proxy.so
Add the following to
<VirtualHost *:80> ServerName devsite.andrew.dyn.dns.com ProxyPreserveHost On ProxyPass / http://192.168.56.10/ ProxyPassReverse / http://192.168.56.10/ </VirtualHost>
Note: I had issues with Firefox timing out with a Proxy Error until I added the
ProxyPreserveHost On line to the VirtualHost.
Finally, restart Apache:
sudo apachectl restart
Test it by visiting http://devsite.andrew.dyn.dns.com and you should see your website.
