使用ssh访问 virtualbox，端口转发

前提环境 ubuntu 1804

安装并开启sshd

apt install openssh-server

service start sshd

设置端口转发

使用ssh -p 12345 root@localhost 访问即可

到此为止下面是牢骚

本来WSL都能搞定大部分场景，但是会把环境搞乱，虽说重装wsl也不麻烦

决定用docker来做实验环境，但发现业界都转k8s了？

不过docker确实很好用，准备用一用，但是wsl仅在hyper-v条件下才支持docker server daemon，基于这个条件，可以server命令启动，也可以安装docker for windows来导入，连接有很多就不列举了

有个issue 解释了半天也没说（或者我没看明白）不用hyper-v能不能用docker，所以只能搞虚拟机，还要在开个窗口麻烦，所以搞个转发wsl访问

这个问题困扰我这工作日最后一天。由于搜索姿势不对怎么也没搜到解决办法。最后琢磨出方法之后，也看到了两个帖子。。

第一个帖子的评论解决了我得问题。

过于全知全能以及轮回视角显得肥肠俗套

还有一篇mvcc 待看 http://openinx.github.io/2015/12/13/ft-mvcc/

本文从工程实现角度解析TokuDB的索引结构－－分形树。 详细描述了ft-index的磁盘存储结构，ft-index如何实现Point-Query, Range-Query, Insert/Delete/Update操作, 并在描述过程中，试图从各个角度和InnoDB的B+树做详细对比。
