利用Vagrant安裝Oracle RAC（默認(rèn)為non-CDB模式），生成2臺虛機(jī)，耗時(shí)約1小時(shí)。

可以看到vagrant生成了node1和node2兩臺虛機(jī)：

Current machine states:

node2                     running (virtualbox)
node1                     running (virtualbox)

This environment represents multiple VMs. The VMs are all listed
above with their current state. For more information about a specific
VM, run `vagrant status NAME`.

兩臺虛機(jī)啟動后，32G的電腦內(nèi)存占用由29%升至69%，消耗內(nèi)存約13G。

空間方面，兩臺虛機(jī)剛生成時(shí)，新增空間占用為vagrant目錄下的113G（共享存儲）加虛機(jī)目錄下的6.13G（各自的操作系統(tǒng)），總共約120G。

存儲使用了ASM：

[grid@node1 ~]$ asmcmd
ASMCMD> lsdg

如果要使用SQL Developer管理此兩RAC示例，則需要連接此兩主機(jī)的公共IP或SCAN IP，例如192.168.56.111和192.168.56.121。他們定義在文件vagrant.yml中：

$ pwd

$ ls
setup.env  vagrant.yml

$ cat vagrant.yml

有幾個(gè)地方可以表明其為RAC。見下圖，RAC #1表明其為集群中的節(jié)點(diǎn)1：

然后就是“數(shù)據(jù)庫狀態(tài)”中，可以看到有2個(gè)實(shí)例，即DB193H11和DB193H12：
