问题
Is it possible to access my Apache server from outside the VirtualBox on Google Chrome browser? Its running on CentOS 7 on VirtualBox. I have tried connecting to the ip address of the CentOS virtual machine but it didn't work. Its using 'Bridged Adapter' networking in the VM settings and i checked the ip address using the 'ip addr' command. Thanks.

Of course you can. Though you need to add a tunnel to allow access to your Centos 7 machine web service from the host machine.
For example, my VM's bridge IP address (the interface that connects to the world) is 192.168.1.38 and its interface is enp0s3. Let's say I'm running the web service on my second interface, enp0s8 with IP 192.168.100.101 on port 8000. Here's how you create the tunnel:
iptables -t nat -A PREROUTING -p tcp -i enp0s3 --dport 80 -j DNAT --to-destination 192.168.100.101:8000
services iptables save
That's it. You should be able to go to your host's Chrome browser and type in the url 192.168.1.38 and be presented with your web service. If it's still not working I'd suggest looking into your iptables rules to see if any is blocking this traffic.
