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 |
|

|
33 |
|
|
<ul> |
34 |

</li> |
37 |

<li> |
38 |
dertobi123 |
1.17 |
If you do not use prebuilt packages, you need at least 300 MB of memory (RAM + |
39 |
sejo |
1.24 |
swap), if you do use prebuilt packages you need at least 64 MB of memory to boot the system. |

Still interested in trying out Gentoo? Well, then it is now time to |
63 |
|
|
choose the installation medium you want to use. Yes, you have the |
64 |
|
|
choice, no, they are not all equal, and yes, the result is always the same: a |
65 |
|
|
Gentoo base system. |
66 |
|
|
</p> |
67 |
|
|
|
68 |
|
|
<p> |
69 |
|
|
The installation media we will describe are: |
70 |
|
|
</p> |
71 |
|
|
|
72 |
|
|
<ul> |
73 |
|
|
<li>Gentoo's Minimal LiveCD</li> |
74 |
|
|
<li>Gentoo's Universal LiveCD</li> |
75 |
|
|
</ul> |
76 |
|
|
|
77 |
|
|
<p> |
78 |
|
|
Every single media has its advantages and disadvantages. We will list |
79 |
|
|
the pros and cons of every medium so you have all the information to |
80 |
|
|
make a justified decision. But before we continue, let's explain our |
81 |
|
|
three-stage installation. |

<title>The Three Stages</title> |

|
Gentoo Linux can be installed using one of three <e>stage</e> tarball files. |
92 |
|
|
The one you choose depends on how much of the system you want to compile |
93 |
|
|
yourself. The <e>stage1</e> tarball is used when you want to bootstrap and |
94 |
|
|
build the entire system from scratch. The <e>stage2</e> tarball is used for |
95 |
|
|
building the entire system from a bootstrapped "semi-compiled" state. |
96 |
|
|
The <e>stage3</e> tarball already contains a basic Gentoo Linux system that has |
97 |
|
|
been built for you. As we will explain later, you can also install |
98 |
|
|
Gentoo without compiling anything (except your kernel and some optional |
99 |
|
|
packages). If you want this, you have to use a <e>stage3</e> tarball. |
100 |
|
|
</p> |
101 |
|
|
|
102 |
|
|
<p> |
103 |
|
|
Now what stage do you have to choose? |
104 |
|
|
</p> |
105 |
|
|
|
106 |
|
|
<p> |
107 |
|
|
Starting from a <e>stage1</e> allows you to have total control over the |
108 |
|
|
optimization settings and optional build-time functionality that is |
109 |
|
|
initially enabled on your system. This makes <e>stage1</e> installs good for |
110 |
|
|
power users who know what they are doing. It is also a great |
111 |
|
|
installation method for those who would like to know more about the |
112 |
|
|
inner workings of Gentoo Linux. |

208 |

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

210 |

and were carefully chosen to enhance performance while maintaining |

Write down (or remember) what stage you want to use. You need this later when |
240 |
|
|
you decide what LiveCD (or other installation medium) you want to use. You might |
241 |
|
|
be interested to know that, if you decide to use different optimization settings |
242 |
|
|
after having installed Gentoo, you will be able to recompile your entire system |
243 |
|

with the new optimization settings. |

The <e>Gentoo LiveCDs</e> are bootable CDs which contain a |
270 |
|
|
self-sustained Gentoo environment. They allow you to boot Linux from the CD. |
271 |
|
|
During the boot process your hardware is detected and the appropriate drivers |
272 |
|
|
are loaded. They are maintained by Gentoo developers. |

274 |
|
|

All LiveCDs allow you to boot, set up networking, initialize your |
277 |
swift |
1.1 |
partitions and start installing Gentoo from the Internet. However, some |
278 |
|
|
LiveCDs also contain all necessary source code so you are able to install |
279 |
|
|
Gentoo without a working network configuration. |

Gentoo's Universal LiveCD is a bootable CD suitable to install Gentoo without |
338 |
|
|
networking. It contains a stage1 and several stage3 tarballs (optimized for the |
339 |
|
|
individual subarchitectures). For example the ppc variant of this CD is called |
340 |
dertobi123 |
1.17 |
<c>install-ppc-universal-2004.2.iso</c> and can be found in the |

If you take a closer look on our mirrors, you will see |
346 |
|
|
that we provide <e>Gentoo Package CDs</e>. This CD (which isn't |
347 |
swift |
1.1 |
bootable) only contains precompiled packages and can be used to install software |
348 |
|
|
after a succesfull Gentoo Installation. To install Gentoo, you only |
349 |
|
|
need the Universal LiveCD, but if you want OpenOffice.org, Mozilla, KDE, GNOME |
350 |
|
|
etc. without having to compile every single one of them, you need the Packages |
351 |

You have chosen to use a Gentoo LiveCD (if not, then you are reading the |
400 |
|
|
wrong section). We'll first start by downloading and burning the chosen |
401 |
|
|
LiveCD. We previously discussed the several available LiveCDs, but where can you |
402 |
|
|
find them? |
403 |
|
|
</p> |
404 |
|
|
|
405 |
|
|
<p> |
406 |
|
|
Visit one of our <uri |
407 |
|
|
link="/main/en/mirrors.xml">mirrors</uri> and go to |
408 |
dertobi123 |
1.17 |
<path>releases/ppc/2004.2/livecd</path>, which is |
409 |
swift |
1.1 |
the path where the LiveCD(s) of your choice are located. Inside that |
410 |
|
|
directory you'll find so-called ISO-files. Those are full CD images |
411 |
|
|
which you can write on a CD-R. |
412 |
|
|
</p> |
413 |
|
|
|
414 |
|
|
<p> |
415 |
|
|
In case you wonder if your downloaded file is corrupted or not, you can |
416 |
|
|
check its MD5 checksum and compare it with the MD5 checksum we provide (such as |
417 |
dertobi123 |
1.17 |
<path>install-ppc-minimal-2004.2.iso.md5</path>). You can check the MD5 checksum |
418 |
swift |
1.1 |
with the <c>md5sum</c> tool under Linux/Unix or <uri |
419 |
neysx |
1.16 |
link="http://www.etree.org/md5com.html">md5sum</uri> for Windows. |
420 |
swift |
1.1 |
</p> |
421 |
|
|
|
422 |
|
|
<p> |
423 |
dertobi123 |
1.17 |
As long as Mac OS X does not support <c>md5sum</c> you have to use the md5 |
424 |
|
|
capability of <c>openssl</c>. Therefore type in Terminal.app: |
425 |
swift |
1.12 |
</p> |
426 |
|
|
|
427 |
dertobi123 |
1.18 |
<pre caption="md5sum with the help of openssl"> |
428 |
dertobi123 |

431 |

|
|
432 |

<p> |
433 |

1.17 |
Now compare this output with the appropriate file found on the server where you |
434 |
|
|
downloaded the ISO (the file will end with .md5). If it is the same, the ISO |
435 |
|
|
image downloaded correctly. Be sure you have not mounted it (e.g. with Disk |
436 |
|
|
Copy) yet! |

To burn the downloaded ISO(s), you have to select raw-burning. How you |
446 |
swift |
1.14 |
do this is highly program-dependent. We will discuss <c>cdrecord</c> and |

<ul> |

<li> |
454 |
|
|
With cdrecord, you simply type <c>cdrecord dev=/dev/hdc</c> (replace |
455 |
|
|
<path>/dev/hdc</path> with your CD-RW drive's device path) followed |
456 |
|

by the path to the ISO file :) |

With k3b, select <c>Tools</c> > <c>CD</c> > <c>Burn Image</c>. Then |
460 |
bennyc |
1.6 |
you can locate your ISO file within the 'Image to Burn' area. Finally click |

On NewWorld machines place the LiveCD in the CD-ROM and reboot the system. When |
476 |
|
|
the system-start-bell sounds, simply hold down the 'C' until the CD loads. |
477 |

<p> |

If you have an OldWorld Mac the bootable portion of the livecd can't be used. |
481 |
|
|
Instead you need to download <uri |
482 |
|
|
link="http://penguinppc.org/projects/bootx/">BootX</uri> and have a working |
483 |
|
|
MacOS installed on your system. You need to copy the <c>BootX Extension</c> from |
484 |
|
|
the unpacked archive-file into the <c>Extensions Folder</c> and make a new |
485 |
|
|
directory called <c>Linux Kernels</c> in the System Folder. In the next step you |
486 |
|
|
need to copy the <c>G3</c> kernel and the <c>initrd.img.gz</c> from the LiveCD |
487 |
|
|
into the <c>Linux Kernels</c> directory. Then reboot the system and wait for |
488 |
|
|
BootX to load. After BootX loaded you still have to set up a few items. In the |
489 |
cam |
1.19 |
options dialog you need to check <c>Use Specified RAM Disk</c> and select the |
490 |
dertobi123 |
1.17 |
<c>initrd.img.gz</c> which you put in the <c>Linux Kernels</c> directory. The |
491 |
|
|
ramdisk size should be set to at least <c>32000</c>. Furthermore the kernel |
492 |
|
|
argument needs to be set to <c>rw init=/linuxrc cdroot</c>. Eventually you are |
493 |
|
|
able to boot the LiveCD when you select Linux on Startup. |
494 |
|
|
</p> |
495 |
|
|
|
496 |
|
|
<p> |
497 |
|
|
After the LiveCD loaded, you will be greeted by a friendly welcome message and a |
498 |
|
|
<e>boot:</e> prompt at the bottom of the screen. |
499 |
swift |

</p> |

<p> |
502 |
|
|
At this prompt you are able to select a kernel for the subarchitecture you use. |
503 |
dertobi123 |
1.17 |
We provide <c>G3</c>, <c>G4</c> and <c>G5</c>. All kernels are built with |
504 |
|
|
support for multiple CPUs, but they will boot on single processor machines as |
505 |
|
|
well. |
506 |
swift |

</p> |
507 |
|
|
|
508 |

You are also able to tweak some kernel options at this prompt. The following |

When the LiveCD boots, it tries to detect all your hardware devices and |
622 |
swift |
1.1 |
loads the appropriate kernel modules to support your hardware. In the |
623 |
dertobi123 |
1.17 |
vast majority of cases, it does a very good job. However, in some cases, it may |
624 |
|
|
not auto-load the kernel modules you need. If the PCI auto-detection missed some |

of your system's hardware, you will have to load the appropriate kernel modules |

If you plan on giving other people access to your installation |
674 |
|
|
environment or you want to chat using <c>irssi</c> without root privileges (for |
675 |
|
|
security reasons), you need to create the necessary user accounts and change |
676 |
|
|
the root password. |
677 |
|
|
</p> |
678 |
|
|
|
679 |
|

<p> |
680 |

To change the root password, use the <c>passwd</c> utility: |
681 |

Re-enter password: <comment>(Re-enter your password)</comment> |

To create a user account, we first enter their credentials, followed by |
691 |
swift |

its password. We use <c>useradd</c> and <c>passwd</c> for these tasks. |
692 |
|
|
In the next example, we create a user called "john". |

If you want to view the Gentoo Handbook (either from-CD or online) during the |
719 |
|
|
installation, make sure you have created a user account (see <uri |
720 |
|
|
link="#useraccouts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to |
721 |
|
|
go to a new terminal and log in. |

|
|
</p> |
723 |

<p> |

If you want to view the documentation on the CD you can immediately run |
726 |
|
|
<c>links2</c> to read it: |

However, it is preferred that you use the online Gentoo Handbook as it will be |
735 |
|
|
more recent than the one provided on the CD. You can view it using <c>links2</c> |
736 |
|
|
as well, but only after having completed the <e>Configuring your Network</e> |
737 |
|

chapter (otherwise you won't be able to go on the Internet to view the |

If you want to allow other users to access your computer during the |
757 |
|
|
Gentoo installation (perhaps because those users are going to help you |
758 |
|
|
install Gentoo, or even do it for you), you need to create a user |
759 |
|
|
account for them and perhaps even provide them with your root password |
760 |
|
|
(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user). |

|
|
</p> |
762 |
|

To fire up the SSH daemon, execute the following command: |
