Before we start, we first list what hardware requirements you need to |
18 |
|
|
successfully install Gentoo on your box. This of course depends on your |
19 |
|
|
architecture. |

Check the following requirements before you |
30 |
|
|
continue with the Gentoo installation: |
31 |
|
|
</p> |
32 |
|
|
|
33 |
|
|
<ul> |
34 |
|
|
<li> |
35 |
|
|
You need at least 1 Gb of free disk space |
36 |
|
|
</li> |
37 |
|
|
<li> |
38 |
|
|
If you do not use prebuilt packages, you need at least 300 Mb of memory (RAM + |
39 |
|
|
swap) |
40 |
|
|
</li> |
41 |
|
|

Still interested in trying out Gentoo? Well, then it is now time to |
58 |
|
|
choose the installation medium you want to use. Yes, you have the |
59 |
|
|
choice, no, they are not all equal, and yes, the result is always the same: a |
60 |
|
|
Gentoo base system. |
61 |
|
|
</p> |
62 |
|
|
|
63 |
|
|
<p> |
64 |
|
|
The installation media we will describe are: |
65 |
|
|
</p> |
66 |
|
|
|
67 |
|
|
<ul> |
68 |
|
|
<li>Gentoo's Minimal LiveCD</li> |
69 |
|
|
<li>Gentoo's Universal LiveCD</li> |
70 |
|
|
</ul> |
71 |
|
|
|
72 |
|
|
<p> |
73 |
|
|
Every single media has its advantages and disadvantages. We will list |
74 |
|
|
the pros and cons of every medium so you have all the information to |
75 |
|
|
make a justified decision. But before we continue, let's explain our |
76 |
|
|
three-stage installation. |

<title>The Three Stages</title> |

|
|
<body> |

|

|

<p> |

|
|
Gentoo Linux can be installed using one of three <e>stage</e> tarball files. |
87 |
|
|
The one you choose depends on how much of the system you want to compile |
88 |
|
|
yourself. The <e>stage1</e> tarball is used when you want to bootstrap and |
89 |
|
|
build the entire system from scratch. The <e>stage2</e> tarball is used for |
90 |
|
|
building the entire system from a bootstrapped "semi-compiled" state. |
91 |
|
|
The <e>stage3</e> tarball already contains a basic Gentoo Linux system that has |
92 |
|
|
been built for you. As we will explain later, you can also install |
93 |
|
|
Gentoo without compiling anything (except your kernel and some optional |
94 |
|
|
packages). If you want this, you have to use a <e>stage3</e> tarball. |
95 |
|
|
</p> |
96 |
|
|
|
97 |
|
|
<p> |
98 |
|
|
Now what stage do you have to choose? |
99 |
|
|
</p> |
100 |
|
|
|
101 |
|
|
<p> |
102 |
|
|
Starting from a <e>stage1</e> allows you to have total control over the |
103 |
|
|
optimization settings and optional build-time functionality that is |
104 |
|
|
initially enabled on your system. This makes <e>stage1</e> installs good for |
105 |
|
|
power users who know what they are doing. It is also a great |
106 |
|
|
installation method for those who would like to know more about the |
107 |
|
|
inner workings of Gentoo Linux. |

Choosing to go with a <e>stage3</e> allows for the fastest install of Gentoo |
181 |
|

Linux, but also means that your base system will have the optimization |

settings that we chose for you (which to be honest, are good settings |
183 |
|
|
and were carefully chosen to enhance performance while maintaining |

Write down (or remember) what stage you want to use. You need this later when |
209 |
|
|
you decide what LiveCD (or other installation medium) you want to use. You might |
210 |
|
|
be interested to know that, if you decide to use different optimization settings |
211 |
|
|
after having installed Gentoo, you will be able to recompile your entire system |
212 |
|
|
with the new optimization settings. |

The <e>Gentoo LiveCDs</e> are bootable CDs which contain a |
227 |
|
|
self-sustained Gentoo environment. They allow you to boot Linux from the CD. |
228 |
|
|
During the boot process your hardware is detected and the appropriate drivers |
229 |
|
|
are loaded. They are maintained by Gentoo developers. |
230 |
|
|
</p> |
231 |
|
|
|
232 |
|
|
<p> |
233 |
|
|
All LiveCDs allow you to boot, setup networking, initialize your |
234 |
|
|
partitions and start installing Gentoo from the Internet. However, some |
235 |
|
|
LiveCDs also contain all necessary source code so you are able to install |
236 |
|
|
Gentoo without a working network configuration. |
237 |
|
|
</p> |
238 |
|
|
|
239 |
|
|
<p> |
240 |

Now what do these LiveCDs contain? |

This is a small, no-nonsense, bootable CD which sole purpose is to boot the |
251 |
|
|
system, prepare the networking and continue with the Gentoo installation. It |
252 |
|
|
does not contain any stages (or, in some cases, a single stage1 file), |
253 |
|
|
source code or precompiled packages. For example the sparc64 variant of this |

LiveCD can be found in the <path>sparc64/</path> subdirectory and is called |

Gentoo's Universal LiveCD is a bootable CD suitable to install Gentoo without |
295 |
|
|
networking. It contains a stage1 and stage3 tarballs (optimized for the |
296 |
|
|
sparc architecture). For example the sparc64 variant of this CD is called |
297 |
swift |
1.6 |
<c>install-sparc64-universal-2004.1.iso</c> and can be found in the |
298 |
swift |
1.1 |
<path>sparc64/</path> subdirectory. |

<p> |
302 |
|
|
If you take a closer look into the directories you will see |
303 |
|
|
that we provide a <e>Gentoo Package CD</e>. This CD (which isn't |
304 |
|
|
bootable) only contains precompiled packages and can be used to install software |
305 |
|
|
after a succesfull Gentoo Installation. To install Gentoo, you only |
306 |
|
|
need the Universal LiveCD, but if you want OpenOffice.org, Mozilla, KDE, GNOME |
307 |
|
|
etc. without having to compile every single one of them, you need the Packages |
308 |
|
|
CD too. Such a Packages CD for sparc64 is called |
309 |
swift |
1.6 |
<c>packages-sparc64-2004.1.iso</c>. |

In case you wonder if your downloaded file is corrupted or not, you can |
367 |
|
|
check its MD5 checksum and compare it with the MD5 checksum we provide (such as |
368 |
swift |
1.6 |
<path>install-sparc64-minimal-2004.1.iso.md5</path>). You can check the MD5 |
369 |
swift |
1.1 |
checksum with the <c>md5sum</c> tool under Linux/Unix or <uri |
370 |
|
|
link="http://www.md5summer.org">md5summer</uri> for Windows. |

To burn the downloaded ISO(s), you have to select raw-burning. How you |
375 |
|
|
do this is highly program-dependent. We will discuss a couple of popular |
376 |
|
|
tools on how to do this. |
377 |
|
|
</p> |
378 |

|
|
379 |
|
|
<ul> |
380 |
|
|
<li> |
381 |
|
|
With EasyCD Creator you select <c>File</c>, <c>Record CD |
382 |
|
|
from CD image</c>. Then you change the <c>Files of type</c> to <c>ISO image |
383 |
|
|
file</c>. Then locate the ISO file and click <c>Open</c>. When you click on |
384 |
|
|
<c>Start recording</c> the ISO image will be burned correctly onto the CD-R. |
385 |
|
|
</li> |
386 |
|
|
<li> |
387 |
|
|
With Nero Burning ROM, select <c>File</c>, <c>Burn CD image</c>. Set the |
388 |
|
|
type of file to <c>*.*</c> and select the ISO file. Older versions of Nero |
389 |
|
|
will tell you they don't recognize the format -- confirm here, it does |
390 |
|
|
recognize it but doesn't know it yet :) In the next dialog, set the |
391 |
|
|
following parameters: |
392 |
|
|
<ul> |
393 |
|
|
<li>Type of image: <c>Data Mode 1</c></li> |
394 |
|
|
<li>Block size: <c>2048 bytes</c></li> |
395 |
|
|
<li>File precursor and length of the image trailer: <c>0 bytes</c></li> |
396 |
|
|
<li>Scrambled: <c>no</c></li> |
397 |
|
|
<li>Swapped: <c>no</c></li> |
398 |
|
|
</ul> |
399 |
|
|
Now click on <c>OK</c> and then <c>Burn</c> (the CD-R) |
400 |
|
|
</li> |
401 |
|
|
<li> |
402 |
|
|
With cdrecord, you simply type <c>cdrecord dev=/dev/hdc</c> (replace |
403 |
|
|
<path>/dev/hdc</path> with your CD-RW drive's device path) followed |
404 |
|
|
by the path to the ISO file :) |

With K3B, select <c>Tools</c> > <c>CD</c> > <c>Burn Image</c>. Then |
408 |
|
|
you can locate your ISO file within the 'Image to Burn' area. Finally click |
409 |
swift |
1.2 |
<c>Start</c>. |

If you are an advanced user, you might want to tweak the IDE hard disk |
488 |

|
performance using <c>hdparm</c>. With the <c>-tT</c> options you can |
489 |

test the performance of your disk (execute it several times to get a |
490 |

If you want to allow other users to access your computer during the |
561 |
|
|
Gentoo installation (perhaps because those users are going to help you |
562 |
|
|
install Gentoo, or even do it for you), you need to create a user |
563 |
|
|
account for them and perhaps even provide them with your root password |
564 |
|
|
(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user). |
