在上一篇文章中，我写了使用VAGRANT 快速安装ORACLE DATABASE 18C。在这篇文章中，我们将学习如何使用Vagrant访问Oracle 18c数据库。首先我们需要检查VM的状态。使用上篇文章用到的Vagrant global-status命令。
PS G:\VM DATA\vagrant-boxes\OracleDatabase\18.3.0> vagrant global-status id name provider state directory ---------------------------------------------------------------------------------------------- b1be299 oracle-18c-vagrant virtualbox running G:/VM DATA/vagrant-boxes/OracleDatabase/18.3.0 The above shows information about all known Vagrant environments on this machine. This data is cached and may not be completely up-to-date (use "vagrant global-status --prune" to prune invalid entries). To interact with any of the machines, you can go to that directory and run Vagrant, or you can use the ID directly with Vagrant commands from any directory. For example: "vagrant destroy 1a2b3c4d"
接下来我们可以打开Virtual Box虚拟机看一下状态。通过上一篇文章我们的操作系统自动创建了一个叫oracle-18c-vagrant的虚拟机。
然后我们可以使用vagrant ssh命令登陆进主机。
PS G:\VM DATA\vagrant-boxes\OracleDatabase\18.3.0> vagrant ssh

切换到Oracle用户之后，我们就可以执行一系列的命令来玩Oracle 18c了。
[oracle@oracle-18c-vagrant ~]$ ps -ef | grep pmon

我们安装VM，默认在oracle用户的home目录下。有个setPassword.sh的脚本。这个脚本是给sys,system,pdb_admin设置密码的。
[oracle@oracle-18c-vagrant ~]$ ls -lrt
total 4
-rwxr-xr-x. 1 root root 784 Oct 1 23:21 setPassword.sh

exit;

要想从虚拟机中退出来，输入exit就行了。
[oracle@oracle-18c-vagrant ~]$ exit logout [vagrant@oracle-18c-vagrant ~]$ exit logout Connection to 127.0.0.1 closed.
输入vagrant halt就关闭虚拟机了，如果你要删除整个虚拟机，运行vagrant destroy命令。
PS G:\VM DATA\vagrant-boxes\OracleDatabase\18.3.0> vagrant halt ==> oracle-18c-vagrant: Attempting graceful shutdown of VM...
当然我们还能运行一些命令查看配置情况，例如vagrant port可以查看端口情况，vagrant ssh-config可以查看ssh配置信息。
PS G:\VM DATA\vagrant-boxes\OracleDatabase\18.3.0> vagrant port
The forwarded ports for the machine are listed below. Please note that
these values may differ from values configured in the Vagrantfile if the
provider supports automatic port collision detection and resolution.

5500 (guest) => 5500 (host)
