+# 从零开始学习RISCV-Lab和 LINUX-Lab基础
+> 作者: 周子棠
+> 日期: 2022.11.29
+## 简介
+这系列文章是学习RISCV-Lab 和 LINUX 基础
+
+RISCV-Lab主要是学习应用开发的
+
+LINUX-Lab主要是学习linux内核的
+
+首先，我们要运行操作系统
+## 实验准备
+准备一个泰晓科技的实验盘（在淘宝搜索泰晓科技就可以查询到）
+## RISCV-Lab操作系统的运行
+# 下载RISCV-Lab
+```
+$ git clone https://gitee.com/tinylab/cloud-lab.git
+
+$ cd cloud-lab
+```
+# 运行RISCV-Lab
+```
+$ tools/docker/run riscv-lab
+LOG: Init docker environment ...
+INFO: Resume the stopped riscv-lab
+INFO: Run host side init for riscv-lab
+INFO: Start riscv-lab-25651-4a9553
+riscv-lab-25651-4a9553
+INFO: Wait for lab launching
+INFO: Wait for lab resuming...
+INFO: Please choose one of the login methods:
+
+ 1 bash
+ 2 vnc
+ 3 ssh
+ 4 webssh
+ 5 webvnc
+
+```
+# 选择登录方式
+```
+INFO: Choose the login method: 1
+
+ 1 bash
+
+INFO: Available login methods:
+
+ bash vnc ssh webssh webvnc
+
+INFO: Switch to another method:
+
+ tools/docker/login LOGIN_METHOD
+
+INFO: Running '/home/ubuntu/Develop/cloud-lab/tools/docker/bash'
+```
+# 在里面输入命令
+```
+
+ubuntu@riscv-lab:/labs/riscv-lab$ ls
+COPYING README.en.md README.md
+ubuntu@riscv-lab:/labs/riscv-lab$ uname -a
+Linux riscv-lab 5.15.0-27-generic #28-Ubuntu SMP Thu Apr 14 04:55:28 UTC 2022 riscv64 riscv64 riscv64 GNU/Linux
+ubuntu@riscv-lab:/labs/riscv-lab$ man uname
+This system has been minimized by removing packages and content that are
+not required on a system that users do not log into.
+
+To restore this content, including manpages, you can run the 'unminimize'
+command. You will still need to ensure the 'man-db' package is installed.
+```
+这样我们就成功运行了riscv-lab操作系统了
+## linux-Lab操作系统的运行
+# 首先是要运行
+```
+$ tools/docker/run linux-lab
