Create/configure vagrant user

Login as root.

Enable networking:

# ifup eth0

Create vagrant user:

# useradd vagrant
# passwd vagrant (vagrant)

Configure sudo via visudo:

# visudo

• Disable requiretty:

    # Defaults    requiretty
  

• Add PATH, SSH_AUTH_SOCK to env_keep:

    Defaults    env_keep += "PATH SSH_AUTH_SOCK"
  

• Enable group wheel:

    %wheel  ALL=(ALL)       ALL
  

• Enable user vagrant:

    vagrant ALL=(ALL)       NOPASSWD: ALL
  

• Write file and exit

    <ESC>
    :w
    :q
  

Test login via ssh from separate terminal (may have to temporarily adjust port forwarding to use port other than 2222 if vagrant box is already in use).

$ ssh -p 2222 [email protected]

Setup networking:

$ cat /etc/sysconfig/network-scripts/ifcfg-eth0 && \
sudo sed -i -r -e 's/^(ONBOOT=("?))no/\1yes/' /etc/sysconfig/network-scripts/ifcfg-eth0 && \
cat /etc/sysconfig/network-scripts/ifcfg-eth0

$ cat /etc/sysconfig/network && \
sudo sed -i -r -e 's/^(HOSTNAME=)localhost\.localdomain/\1vagrant-centos-64/' /etc/sysconfig/network && \
cat /etc/sysconfig/network

$ sudo hostname vagrant-centos-64

Install VirtualBox Guest Additions

Devices > Install Guest Additions… (⌘D).

Install packages required for guest additions:

$ sudo yum -y update # note: this step is time consuming
$ sudo reboot # activate new kernel if kernel is updated
$ sudo yum -y install man nano wget which bzip2 gcc make kernel-devel-`uname -r` autoconf

Mount CDROM & run installation script (ignore error related to Window System drivers):

$ sudo sh -c "mount /dev/cdrom /media
sh /media/VBoxLinuxAdditions.run"

Verify presence of kernel module:

$ lsmod | grep vboxsf

vboxsf                 37454  1 
vboxguest             243989  2 vboxsf

Take snapshot (⌘T): Installed VirtualBox Guest Additions

Configure SSH

Configure ~/.ssh:

$ mkdir -m 0700 ~/.ssh && cd ~/.ssh && \
curl -k https://raw.github.com/mitchellh/vagrant/master/keys/vagrant.pub > authorized_keys && \
chmod 0644 authorized_keys

Configure /etc/ssh/sshd_config:

$ FILE=/etc/ssh/sshd_config && \
sudo sh -c "cat \"$FILE\"
sed -i -r -e 's/^#(UseDNS\s)yes/\1no/' \"$FILE\"
cat \"$FILE\""

Restart sshd daemon:

$ sudo /sbin/service sshd restart
