Automatically mount directories in centos / virtualbox

If you try to mount a shared folder in centos, runing under a virtual box, you'll probably have problems trying to fix this directory, mounting automatically each time the system reboots.

In any other distribution, like ubuntu, you just have to go to your /etc/fstab and add this line:

varhtml /var/www/html vboxsf defaults 0 0

The problem is centos is that when the system arrives to this line, the vboxsf module has not been loaded yet.

Installing capistrano in Centos

Very very easy in CentOS, just like it would be in a Debian system:

# yum install ruby -y

# yum install rubygems -y

# gem install capistrano

Really, it couldn't be easier. Next step, just having fun with Capistrano :-)

Accessing centos apache/httpd from vbox host

This is the scenario. You installed vbox in your Mac, windows or Linux computer. Then you´ve installed Centos or Red Hat (or any other Red Hat flavor) in this virtual box.

Next step, installed httpd (apache2) and... even it is running and httpd status confirms it with a "running" message, it cannot be accesible from your host machine.

The problem is on iptables. Red Hat by default denies access to this machine from other (external) machines. Solution? Very easy, open iptables file:

vim /etc/sysconfig/iptables

(vim is my favourite editor for a loooong long time)
