How to set up a new centos 7 VM on MacOS (2019 Winter Holiday Edition)

How to set up a new centos 7 VM on MacOS

⚠️ As of Jan 13, 2020, there is a compatibility issue between VirtualBox and Vagrant, and thus, you need to use VirtualBox ver 6.0 rather than the latest ver 6.1.

Environments

Host

  • MacOS 10.15.2
  • Homebrew 2.2.1
  • VirtualBox 6.0.14
  • Vagrant 2.2.6

Guest

  • CentOS 7
    • Memory: 4GB
    • Change the setting at vb.memory = "4096" in Vagrantfile if you need

Install Xcode

$ xcode-select --install

Install Homebrew

$ sudo chgrp -R admin /usr/local
$ sudo chmod -R g+w /usr/local
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Install VirtualBox

Install Vagrant

$ brew cask install vagrant

Install Vagrant plugins

$ vagrant plugin install vagrant-vbguest

Install CentOS 7 VM Box

$ vagrant box add centos/7
Select N (VirtualBox)
$ mkdir CentOS7; cd CentOS7
$ vagrant init centos-VAGRANTSLASH-7

Prepare VM Settings

Start VM

$ vagrant up --provider=virtualbox

SSH to VM

$ vagrant ssh

How to sync files with VM

  • Host's CentOS7 folder is sync'ed with Guest's /vagrant folder

Stop VM

$ vagrant halt

Uninstall Homebrew

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

# Provider-specific configuration so you can fine-tune various
# backing providers for Vagrant. These expose provider-specific options.
# Example for VirtualBox:
#
config.vm.provider "virtualbox" do |vb|
# # Display the VirtualBox GUI when booting the machine
# vb.gui = true
#
# # Customize the amount of memory on the VM:
vb.memory = "4096"
end
#
# View the documentation for the provider you are using for more
# information on available options.
# Enable provisioning with a shell script. Additional provisioners such as
# Puppet, Chef, Ansible, Salt, and Docker are also available. Please see the
# documentation for more information about their specific syntax and use.
# config.vm.provision "shell", inline: <<-SHELL
# apt-get update
# apt-get install -y apache2
# SHELL
config.vm.provision "shell", path: "Vagrant_provision.sh"
