CentOS7 安装VirtualBox
安装vagrant
yum install -y https://releases.hashicorp.com/vagrant/2.1.2/vagrant_2.1.2_x86_64.rpm
选择 2
安装失败
git clone https://github.com/chef/bentocd bento/ubuntupacker build ubuntu-16.04-amd64.json# adjust for your environmentvagrant box add ../builds/ubuntu-16.04.virtualbox.box --name bento/ubuntu-16.04
使用root用户执行成功
下载Vagrant 脚本 and bash 脚本
$ git clone https://github.com/hyperledger/indy-node.git
$ cd indy-node/environment/vagrant/training/vb-multi-vm
$ git checkout stable建立Indy验证器节点集群
当前目录下的 Vagrantfile，包含了 vagrant说明，virtualbox指令会在你的虚拟机中执行，另外，它指示Vagrant执行 bash文件scripts/validator.sh，在每个虚拟机上来检查验证必要的软件，它还提供了三个代理vm的配置说明，以及一个用作CLI客户端的指令，其中包含了所需的bash配置文件。
该脚本假定在您的pc中可以创建10.20.30.00/24虚拟网络，而不需要与外部网络配置相冲突。将要供应的vm的地址将从这个网络的地址范围中获取。它假设你在美国：Mountain timezone。可以使用文本编辑器对Vagrantfile内容进行更改。您可以按原样运行这个脚本，或者您可能想要：
1）修改时区。对于一个候选列表，请参考/usr/share/zoneinfoon一个Ubuntu系统。
2）修改VM的ip地址
* 修改Vagrantfile中validator、agent中的ip地址
* 修改scripts/validator.sh 第48行对应的validator IP地址列表
* 在etc/hosts文件中更改模板主机文件中的IP地址
配置文件有正确的设置之后，提供验证器和CLI客户机节点：

Vagrant is currently configured to create VirtualBox synced folders with
the `SharedFoldersEnableSymlinksCreate` option enabled. If the Vagrant
guest is not trusted, you may want to disable this option. For more
information on this option, please refer to the VirtualBox manual:
https://www.virtualbox.org/manual/ch04.html#sharedfolders
This option can be disabled globally with an environment variable:
VAGRANT_DISABLE_VBOXSYMLINKCREATE=1
or on a per folder basis within the Vagrantfile:
config.vm.synced_folder '/host/path', '/guest/path', SharedFoldersEnableSymlinksCreate: false

Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.
If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.
If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.
If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.解决：
编辑Vagrantfile ，添加如下文件
config.ssh.username = "vagrant" config.ssh.password = "vagrant"
然后重启vagrant 重新加载配置文件
vagrant halt vagrant upvagrant destory
阿里云本身就是虚拟系统，不能再安装 virtualBox了
