Vagrant+VirtualBox安装CentOS

自从用了VirtualBox+Vagrant组合，本地使用虚拟机不知道有多爽。

安装VirtualBox

Oracle VM VirtualBox 是免费的，用起来很顺手。
下载地址：https://www.virtualbox.org/wiki/Downloads
傻瓜式安装。

安装Vagrant

下载地址：https://developer.hashicorp.com/vagrant/downloads
本地新建目录D:\develop\VirtualBox VMs\centos\node01，进入cmd命令
官网镜像：https://app.vagrantup.com/boxes/search
第三方镜像：www.vagrantbox.es。

vagrant init qarham/CentOS7.5-350GB --box-version 1.0

本次使用的官网镜像，速度上很快。第三方镜像需要执行如下命令：

 $ vagrant box add {title} {url}
 $ vagrant init {title}
 $ vagrant up

等待执行完成后，修改目录中的vagrant文件

# All Vagrant configuration is done below. The "2" in Vagrant.configure
# configures the configuration version (we support older styles for
# backwards compatibility). Please don't change it unless you know what
# you're doing.
Vagrant.configure("2") do |config|
  # The most common configuration options are documented and commented below.
  # For a complete reference, please see the online documentation at
  # https://docs.vagrantup.com.

  # Every Vagrant development environment requires a box. You can search for
  # boxes at https://vagrantcloud.com/search.
  config.vm.box = "qarham/CentOS7.5-350GB"
  config.vm.box_version = "1.0"

  # Disable automatic box update checking. If you disable this, then
  # boxes will only be checked for updates when the user runs
  # `vagrant box outdated`. This is not recommended.
  # config.vm.box_check_update = false

  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine. In the example below,
  # accessing "localhost:8080" will access port 80 on the guest machine.
  # NOTE: This will enable public access to the opened port
  # config.vm.network "forwarded_port", guest: 80, host: 8080

  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine and only allow access
  # via 127.0.0.1 to disable public access
  # config.vm.network "forwarded_port", guest: 80, host: 8080, host_ip: "127.0.0.1"

  # Create a private network, which allows host-only access to the machine
  # using a specific IP.
  config.vm.network "private_network", ip: "192.168.33.11"

  # Create a public network, which generally matched to bridged network.
  # Bridged networks make the machine appear as another physical device on
  # your network.
  # config.vm.network "public_network"

  # Share an additional folder to the guest VM. The first argument is
  # the path on the host to the actual folder. The second argument is
  # the path on the guest to mount the folder. And the optional third
  # argument is a set of non-required options.
  # config.vm.synced_folder "../data", "/vagrant_data"

  # 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 = false
	 
	 vb.cpus=2
  
     # Customize the amount of memory on the VM:
     vb.memory = "1024"
  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
  # Ansible, Chef, Docker, Puppet and Salt 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
end

可以把本地文件中的内容和上面的对比。

网络设置

本地执行ipconfig（windows环境）

D:\develop\VirtualBox VMs\centos\node01>ipconfig

可以看到地址，只要不重复，对应修改就可以了。

内存和CPU

	 vb.cpus=2  # 设置cpu核数
  
     # Customize the amount of memory on the VM:
     vb.memory = "1024"  # 设置内存（单位：M）

启动

 $ vagrant up

默认创建了用户vagrant，密码vagrant。

重启

修改配置，需要重启

 $ vagrant reload

关闭

修改配置，需要重启

 $ vagrant halt

其他命令可以去官网自行查看。
