《胡须Linux教程》#1 课程介绍

Linux Sysadmin Basics -- Course Introduction

嗨 我是Dave
Hey, I’m Dave,
这是一套关于Linux的视频课程
and this is a Linux video course.
其实 我一开始做这个课程是为了一个朋友
I started making this for a friend,
但是后来我想 或许其他人也能从课程中受益
but I figured other people could benefit.
我准备花点时间说说Linux
And if I’m gonna take time to really cover Linux from, sort of,
这些基础将通向中等或者高级管理者的水平
the basics all the way to an intermediate/advanced administrator level,
我觉得别人也会从中受益
I just figured it’s something that other people could benefit from.
那么为什么一定是Linux呢
Why Linux? Well,
首先 Linux非常酷 它有庞大的社区
Linux is cool, it’s got a huge community,
它是一种很前沿的 而且有很多难以想象的东西运行在Linux上面
it’s sort of cutting-edge…an unbelievable amount of stuff runs on Linux.
因此比如说 就万维网所占的比例而言
So if you, like, in terms of percentage of the world’s websites,
或者邮箱服务器 或者这些所有运行在Linux上的服务
or mail servers, or just all these services runs on Linux.
并且越来越多 还包括客户端系统
And more and more, also client systems, so,
终端用户系统 也就是说甚至是商业人士和职员
end-user systems, that is even business people and stuff,
也在使用运行着Linux系统的电脑
are using computers that are running Linux.
他非常棒 而且学起来也很不错 很有趣
It’s great work, it’s awesome to learn, it’s fun to do.
它也恰好成为一个不错的事业
It also happens to be a great career,
而且工资很高
and really well paid.
你也可以的 而且基本上不会在意你的文凭
You can do it, basically, regardless of your formal qualifications,
这意味着 你不需要学着成为一个系统管理者
that is, you don’t need to study to become a system administrator,
或者从此开始你的职业生涯
or start your career in this.
你不需要一个学位
You don’t need a degree,
一般来说 人们只是为了学习系统使用的技能
generally, people are just looking for skill,
学习系统的相关知识
knowledge about the systems,
有一些使用工具的经验 应用于生产环境下
and some experience in using the tools, that are used in production,
还有一些在Linux上的程序之类的东西
so the programmes and stuff in Linux.
所以这是一个很棒的事情
So, this is a great thing to do,
如果你只是想找一个很酷的东西来学习或者改变职业
if you’re just looking for a cool thing to learn, or a career change,
或者想去理解更多关于计算机和安全的知识
or, to understand more about computers and security.
这都可以让你做一些很酷的事情
It allows you to do cool stuff,
甚至你不需要对关于Linux的职业感兴趣
even if you’re not interested in a career in Linux,
只是在家运行一大堆服务 也是很有乐趣的
like, just running a bunch of services at home, it’s a lot of fun to have, like,
比如搭一个BT种子服务器 当然 种子得是合法的
a torrent server that’s always downloading the torrents, legal torrents, of course.
因为你从不该去做违法的事情
Because you would never do anything illegal.
或是 为你的朋友家人
Or things like, setting up a streaming movie server,
搭建一个流影片服务器
for your friends, or your family at your house.
他们和运行Linux没关系
Doesn’t matter if they’re running Linux,
我的意思是 他们不需要知道 这些服务器运行在Linux上
I mean, they don’t have to know, that the server’s running Linux.
所以他们可以在家的任何角落里看电影电视节目
So they could stream movies or TV shows from anywhere in the house,
你也可以搭建一个邮箱服务器来保护你的隐私
you could set up a mail server to protect your privacy,
或者你家人的隐私
or the privacy of your family.
你可以在家运行网站论坛或者博客
You could run websites, or forums, or a blog from your house.
你可以构建一个程序运行环境
You could set up a programming environment,
或者学习一些关于安全的知识
or you could learn stuff like security,
或者你知道的所谓的黑客
or you know, quote unquote hacking,
这只是个误称 但是之后我们将会涉及那些
which is a misnomer, but we’ll get into that later.
所以最后 这些课程是怎么学习的呢
So basically how this course works,
这需要要你花费一些精力
it requires a small commitment from you, and that is,
这意味着真的从这些课程中得到所有的价值 你得保证去做
to really get the full value out of this course, you have to commit to it,
就像我们说的 如果你在30天里每天都看这些视频
just, let’s say, for 30 days if you watch these videos every day.
并且你按照我制作的顺序看
And you watch it in the order that I create the videos in.
在家尝试了所有的内容
You try everything at home,
因为仅仅是看是并不够的
just watching these isn’t going to be enough.
为了给你一个扎实的理解
To give you a solid understanding,
你的手指得去敲这些我敲过的命令
your fingers have to type these things that I’m typing,
你得反复使用它们
and you have to play around with them,
即便是在视频结束后
even once the video ends.
在家尝试不要害怕弄坏什么东西
So experiment at home, and don’t be afraid to break stuff.
我们会用一个虚拟机运行Linux
We’re going to use a virtual machine to run Linux in,
因此 这是你的一个小实验环境
so you have a little play environment,
甚至如果你是Mac OS X或者Windows系统
even if you’ve got Mac OS X or, Windows,
都可以运行Linux
you can run some Linux,
就像运行其他应用程序一样
just like any other application,
这样可以随便做实验
and experiment around.
就算被你破坏了 也没事
And if you blow it away, then it’s ok,
你可以开始乱来一下而不会对剩下的系统有伤害
you could just start from scratch without hurting the rest of your system.
这非常的安… 变得非常安全
It’s very sa…it’s become very safe.
老天才知道我学这些东西的时候
God knows when I was learning this stuff,
我破坏了父母的机器好多次
I blew away my parents’ machines so many times and,
我觉得我弄丢了所有的数据 我指的是所有东西都不在了
I think I lost our data once, I mean just everything was gone.
你现在不需要再有什么风险了
You don’t need to run that risk anymore,
计算机现在非常强大
computers are so powerful now,
你可以在一个操作系统中再运行一个操作系统
that you can run operating systems inside of other operating systems.
所以尤其是在这门课所涉及的东西
So, what’s covered in this course, specifically,
如果你上完了这门课
If you go through this course,
我的承诺是帮你理解Linux如何工作
my commitment is to help you understand how Linux works,
而不仅仅是表面皮毛
not just on the surface.
在家运行Linux
You know, Linu…running Linux at home,
在这10年已经变得难以置信的简单
has become incredibly easy over the last ten years.
如果你仅仅想在家里运行Linux
You know, you never have to look at a command line utility,
其实根本就用不上命令行工具
if you just want to run Linux at home.
这当然很好
And it’s great for that, like,
就像我在我奶奶电脑上安装的软件一样
it’s what I would install on my grandmother’s computer,
因为
because, you know,
使用默认配置的话很安全 也很容易
it’s going to be the most secure and simple-to-use thing by default,
对于只使用像Email和Facebook
for people who just use things like email and Facebook,
还有上网的人来说
and, and, you know, like, browse the web,
现在这几乎是所有人的都应该会的
which is almost everyone these days.
但我们教的并不是这些
But this isn’t that,
这不仅仅是一个在家运行Linux桌面系统的教程
this is not a guide to running, like, a Linux desktop at home.
这是一个对Linux系统的深入探索
This is a deep dive into the Linux system itself,
这真的会帮助你理解操作系统
it’s really going to help you understand the operating system.
这也会允许你做所有事情
And that will allow you to do all kinds of things,
这是一个比只是在家运行一个桌面系统更酷的方式
that are way, way cooler than just running a desktop system at home.
这门课将会有很多命令行操作
This course is going to be command line heavy.
关于… 我想说出所有的
About…I want to say everything,
但是你知道我会有时候不小心违背承诺
but, you know, I, I know I’m going to break that promise at some point, but,
但是我将给你展示的东西的百分之99
like 99% of what I’m going to show you,
都会是在Shell中完成的
is done, in the Shell.
所以这些就是你在这个环境中看到的
So, in this environment that you’re seeing here.
我们将会帮你成为一个命令行达人
We’re going to, help you become a command line wiz.
现在我会聚焦于最常见的Shell
Right now I’m going to be focusing on the most common Shell,
在最流行的Linux发行版中非常常见
commonly found in the most popular Linux distributions.
这就是Bash Bourne Again SHell的缩写
And that’s Bash, the Bourbe Again SHell.
我们会谈到启动进程和在其中的系统
We’re going to talk about the boot process and the system in it.
这是Linux内核和用户空间的起点
So the start up of a Linux Kernel and Userland stuff.
我们会说到访问控制和root身份
We’re going to talk about access control, and root,
也就是最高权限
or God powers.
我们会说到文件系统怎么被设定
We’re going to talk about how the file system is laid out,
以及所有东西 如何运行
where everything is, how it works.
我们会说到进程控制
We’re going to talk about process control,
控制运行的进程或应用
so, controlling the processes or applications as they run.
我们会尽快地
And then we’re going to get, as quickly as possible,
学习常见系统 管理员任务
into common sys(tem) admin(istrator) tasks.
管理用户 管理内存
So, managing users, managing storage,
管理安装包 安全补丁
managing packages, and security patches,
以及软件更新
updating software.
我们会涉及到最常见的远程工具
We’re going cover the most common remote tools,
用来远程控制系统管理
for remote system administration.
比如SSH – 安全Shell
Just like SSH, Secure Shell,
这是一个带密码的安全Shell 你可以
which is a cryptographically secure, Shell, that you can,
从一个计算机连接到其他计算机 并且就好像在本地使用
connect from one computer to the other, and work on it as if it were local.
还有比如说备份 可以使用那些工具
And, things like backup, that use those tools.
我们都会涉及 比如说
We’re going to cover, sort of,
基本问题的解决和故障排除的方法
basic problem-solving and troubleshooting methodology,
还有其他的比如 log文件在哪
and other things, like, just, you know, where the log files are,
这种
and sort of, good to know stuff like that.
应用配置当然也在其中
Application configuration, of course, is part of this.
你想运行的常见服务
Common services that you would want to run,
或者在生产系统中运行
or would be running in a production system.
通过专业级的设置
So, in a professional setting, like,
甚至是在家
the…or even at home,
真的 我指文件共享 web 像这些你都能在家运行
really, I mean, file sharing, web, like these are all things what you can run from home.
我们还会说安全性
But we’ll also talk security,
会讲授比在家使用更加专业的方式
in a way that’s a little bit more professional than perhaps, you would need at home.
当然这对家用也很有帮助
But, it’s obviously still useful for home use.
我们也会谈论Linux内核本身
We’ll talk about the Linux Kernel itself.
其实 Linux只是
Now Linux really, is just,
一个操作系统的内核
the Kernel, which is the very core of the operating system,
还有操作系统本身
and the operating system itself.
大多数在Linux上使用的软件
But most of the software you’re going to use on Linux is,
是GNU软件
it’s GNU software, so.
这确实是个术语
It’s actually the real term,
还有一个很大的哲学争论在上面
there’s like huge philosophical battles over this,
就是GNU/Linux不仅仅是Linux
but it’s GNU/Linux, not just Linux.
GNU的人听到你只说Linux时 他们会很生气
The GNU people get very angry when you call it just, Linux.
应该是一个Linux内核加上GNU的用户空间系统
So it’s a Linux Kernel and GNU Userland system,
我们会说内核
but we’ll, we’ll talk about the Kernels, so,
在所有东西之下的Linux本身
Linux itself, underneath all there,
我们会看到完整的机器
we’re going to basically peek up the skirt of this whole machine,
看到它是怎么工作的
and see how it all works.
然后那些变成现实
And that’s, that’s starting to get into real,
那已经很多了
that’s in the weeds, basically,
这是非常非常偏技术性的东西
that’s pretty, pretty heavy technical stuff then.
但是到那时你就能理解了
But you be able to understand it by the time we, we get to it.
我们也会谈到网络的基础知识
And that’s also when we’ll cover networking basics,
TCP/IP网络
so TCP/IP networking.
这是Internet工作的基础
Which is, the way the Internet works, basically.
以及那些层结构
And the layers of that,
他们如何交互
and how they interact.
我甚至会涉及一些高级网络和安全知识
And I will even cover some advanced networking and security.
以及一些网络应用程序
So, also some of the networking applications that run,
比如在Internet上路由如何工作
like how routing works on the Internet.
DNS即域名系统如何工作
How DNS, the Domain Name System works,
还有一些
and some,
我还会说一些安全知识
some security knowledge I’ll also cover.
然后我们甚至会关注
And then, we’ll even get into some,
更高级的网络和安全概念
more advanced networking and security concepts,
比如在Internet上路由如何工作
like, routing, how routing works on the Internet.
DNS即Domain Name System
DNS, so the Domain Name System,
入侵检测
intrusion detection,
漏洞扫描
vulnerability scanning,
如果你能掌握的话 就能检查自己的机器
checking your machines to…see if you can get into them,
看看这些是不是容易受到攻击的东西
seeing if they’re vulnerable of things.
然后提供一些更加深入的资料
And then, some resources for going further down that road.
我们不会做破解 入侵测试等
We’re not going to go down, like, the hacking, pen(etration)Testing road,
那些太远了
too far.
但是这的确会给你你确实需要的基础知识
But this certainly will give you the foundation you absolutely need,
如果你曾可能想那样做
if you ever want to do that.
因为你确实不会对任何人有利
Because you’re absolutely no good to anyone,
就像 一个雇佣的黑客 也就是
as, like, a hacker for hire, that is, you know,
一种 做渗透测试的人
sort of, a, a penetration tester,
如果你不知道 我还会告诉你关于TCP/IP的
if you don’t know, like, the fundamentals of TCP/IP Networking,
网络知识
and that’s what I’ll give you here.
如果你们想通过这门课来找到工作
I’ll also, just for those of you who are interested in getting work,
作为一个Linux或Unix系统管理员
as Linux or Unix system administrators,
这是一个非常棒的职业
it’s a phenomenal career.
这是我选择的职业
It is my chosen career.
我会告诉你们一些关于找工作的事
I’ll give you some words on, like, job hunting,
证书也许有用
certifications that might be useful,
像那种额外的技能你也可能需要
additional skills that you might need, that kind of thing.
所以如果你真的跟着这门课的话
So if you really stick with this,
并且投入时间
and you commit to going through this course,
你会学到很多Linux的知识
you’re going to learn a lot about Linux,
这是我给你们的承诺
that is my commitment to you.
好 但是基本上你的奶奶不可能坐下来听这门课的
Good, but, basically, your grandma cannot sit down and take this course.
情况是这样
Here’s the deal,
如果你已经精通了一台电脑
if your already reasonably proficient on a computer,
比如说你知道什么是CPU
like, you know what a CPU is,
你知道那是个处理器
and you know that that’s a processor, and,
你知道随机存储器
you know the difference between memory RAM,
和硬盘空间的区别
and hard drive space,
你也知道什么是命令行什么是Shell
and you know what a command line or shell is,
或者至少听说过这些
or have at least heard of these things,
那你就可以上这门课了
then, you can, you can take this course.
如果你不知道这些东西
If you don’t know these things,
如果你真的是一个电脑新手
if you have real…if you’re sort of a computer newbie,
这门课不适合你
this course is not for you.
你得首先了解一些基础知识
You need to get some basic knowledge first,
然后你就可以听这门课了
and then you can do this.
这门课从中级到高级的计算机用户
This is sort of, starting to be intermediate to advanced computer users,
现在 我会讲这些基础知识
now, I’ll cover the basics,
我会说到非常基础的shell命令
I will cover very basic shell commands,
比如说在Shell中移动文件
like moving around the file system on the Shell.
如果你从来没有在Shell中操作过
So even if you’ve never worked on the Shell before,
或仅仅只是在shell中复制粘贴
or very little, or you’ve only copy and pasted things in there,
尝试做过这些
to try to get things working.
这也没问题 我会说到你需要了解的
That’s fine, we’ll cover what you need to know.
但是我不会说的特别详细
But, I’m not going to cover it in huge detail.
所以你知道的越少
So, the less you know,
你会要做更多的事来赶上我们的进度
the more, kind of, work you’ll have to do to get caught up to where we start.
希望这节课给了大家一个清晰的思路
So, I hope that gives you a good idea of where we’re going,
这门课可以为你做什么
and what this course can do for you.
耶 我们开始吧
Yeah, let’s get started.
刚才是大致的概述
Just general outline,
大部分视频 我会尽可能的简洁
most videos…I’m going to try and keep the videos as short as possible.
这可能会是个相当长的视频
This will hopefully be, a fairly long video,
就根据基础知识视频而言
in terms of the basic set of videos.
但是我们接着会学到更多高级的话题
But then as we get to more advanced topics,
这些显然会花费更多的时间来学习
they’ll obviously require more time to cover, so,
我们会把视频控制在15-20分钟
you know, we’ll get back into the 15 minute to 20 minute video range.
但是对于所有系统管理的东西
But, certainly for all the basics, for all the basic sys admin stuff,
那些我会讲到 每次一个话题
I’m going to cover, really, one topic at a time,
每一个视频一个话题
one topic per video.
我们会一点点积累
And we’re going to built it up,
按顺序了解需要知道的
in the way that we…in the order that we need to know it.
我会做6分钟的视频
I’m aiming for, like, 6 minute videos.
我们看看能差多少
So, we’ll see how close I get, but,
加油
enjoy.
但愿你准备好了
I hope you’re ready,
因为我们就要把你变成可怕的黑客了
we’re going to turn you into a freaking hacker.
