15 The Quick install guide covers the Gentoo install process in a
16 non-verbose manner. Users should already have prior experience with
17 installing Gentoo Linux if they want to follow this guide.

31 <p>
32 Download a CD from one of our <uri link="/main/en/mirrors.xml">mirrors</uri>.
33 You can find the ISOs in
34 <path>releases/&lt;architecture&gt;/&lt;release&gt;/installcd</path>. The
35 <e>minimal</e> installation cd is only useful for internet-based installations;
36 with the <e>universal</e> installation cd you can perform a networkless
37 installation as well.
38 </p>
39
40 <p>
41 <uri link="/doc/en/faq.xml#isoburning">Burn</uri> the CD and boot it. Press
42 <c>F2</c> at the boot screen to find out what boot options exist. Once booted,
43 you need to start the <c>pcmcia</c> init script if you need PCMCIA support.
44 </p>
45
46 <p>
47 The installation cds allow you to start an <c>sshd</c> server, add additional
48 users, run <c>irssi</c> (a command-line chat client) and surf the web using
49 <c>lynx</c> or <c>links2</c>.

54 <section>
55 <title>Network Configuration</title>
56 <body>
57
58 <p>
59 If your network does not work already, you can use <c>net-setup</c> to configure
60 your network. You might need to load support for your network card using
61 <c>modprobe</c> prior to the configuration. If you have ADSL, use
62 <c>adsl-setup</c> and <c>adsl-start</c>. For PPTP support, first edit
63 <path>/etc/ppp/chap-secrets</path> and <path>/etc/ppp/options.pptp</path> and
64 then use <c>pptp &lt;server&nbsp;ip&gt;</c>.
65 </p>
66
67 <p>
68 For wireless access, use <c>iwconfig</c> to set the wireless parameters and then
69 use eiter <c>net-setup</c> again or run <c>ifconfig</c>, <c>dhcpcd</c> and/or
70 <c>route</c> manually.
71 </p>
72
73 <p>
74 If you are behind a proxy, do not forget to initialise your system using
75 <c>export http_proxy</c>, <c>ftp_proxy</c> and <c>RSYNC_PROXY</c>.
76 </p>

81 <title>Preparing the Disks</title>
82 <body>
83
84 <p>
85 Use <c>fdisk</c> or <c>cfdisk</c> to create your partition layout. You need at
86 least a swap partition (type 82) and one Linux partition (type 83).
87 </p>
88
89 <p>
90 Use <c>mke2fs</c>, <c>mke2fs -j</c>, <c>mkreiserfs</c>, <c>mkfs.xfs</c> and
91 <c>mkfs.jfs</c> to create file systems on your Linux partitions. Initialise your
92 swap partition using <c>mkswap</c> and <c>swapon</c>.
93 </p>
94
95 <p>
96 Mount the freshly created file systems on <path>/mnt/gentoo</path>. Create
97 directories for the other mount points (like <path>/mnt/gentoo/boot</path>) if
98 you need them.

104 <title>Setting Up The Stage</title>
105 <body>
106
107 <p>
108 First make sure your date is set correctly using <c>date MMDDhhmmYYYY</c>. Next,
109 download a stage from one of our <uri link="/main/en/mirrors.xml">mirrors</uri>
110 or use the one available on the installation CD
111 (<path>/mnt/cdrom/stages</path>). Go to <path>/mnt/gentoo</path> and unpack the
112 stage using <c>tar&nbsp;-xvjpf&nbsp;&lt;stage&nbsp;tarball&gt;</c>.
113 </p>
114
115 <p>
116 Install a Portage snapshot if you are performing a networkless installation: go
117 to <path>/mnt/gentoo/usr</path> and run
118 <c>tar&nbsp;-xvjf&nbsp;/mnt/cdrom/snapshots/&lt;snapshot&gt;</c>. Other users
119 can download a portage snapshot and install it likewise.
120 </p>
121
122 <p>
123 Edit <path>/mnt/gentoo/etc/make.conf</path> to suit your needs (USE flag, CFLAGS
124 and CXXFLAGS). You can use the <c>nano</c> editor for this.
125 </p>
126
127 </body>
128 </section>
129 <section>
130 <title>Installing the Gentoo Base System</title>
131 <body>
132
133 <p>
134 Mount the <path>/proc</path> file system first and then chroot into your Gentoo
135 environment.
136 </p>
137
138 <pre caption="Preparing and chrooting">
139 # <i>mount -t proc none /mnt/gentoo/proc</i>
140 # <i>chroot /mnt/gentoo /bin/bash</i>
141 # <i>env-update</i> &amp;&amp; <i>source /etc/profile</i>
142 </pre>
143
144 <p>
145 If you are not running a networkless installation, issue <c>emerge --sync</c> to
146 update your Portage tree.
147 </p>
148
149 <p>
150 Next, make sure <path>/etc/make.profile</path> points to the right profile. The
151 default one should suffice for most users; subprofiles are available for
152 different kernels (like <path>2.4/</path> for 2.4-kernel based profiles). Change
153 the profile using <c>ln -sf</c>.
154 </p>
155
156 <ul>
157 <li>
158 Bootstrapping (not available for networkless installations) happens using
159 <c>scripts/bootstrap.sh</c> in the <path>/usr/portage</path> directory.
160 </li>
161 <li>
162 System installation (not available for networkless installations) happens
163 using <c>emerge&nbsp;-e&nbsp;system</c> (or <c>-N</c> if you haven't
164 altered the default CFLAGS/CXXFLAGS).
165 </li>
166 </ul>
167
168 <p>
169 Stage3 users (except those performing a networkless installation) need to
170 upgrade the baselayout package:
171 </p>
172
173 <pre caption="Upgrading baselayout">
174 # <i>CONFIG_PROTECT="-*" emerge baselayout</i>
175 </pre>

179 <section>
180 <title>Kernel Configuration</title>
181 <body>
182
183 <p>
184 Set your time zone information by changing the <path>/etc/localtime</path>
185 symbolic link to the correct location in <path>/usr/share/zoneinfo</path> using
186 <c>ln -sf</c>.
187 </p>
188
189 <p>
190 Install a kernel source (<c>gentoo-sources</c> and <c>vanilla-sources</c> are
191 available for networkless installations) and configure it using <c>make
192 menuconfig</c> followed by <c>make&nbsp;&amp;&amp;make&nbsp;modules_install</c>
193 inside <path>/usr/src/linux</path>. Copy the <path>arch/i386/bzImage</path> file
194 over to <path>/boot</path>. You can also <c>emerge&nbsp;genkernel</c>
195 and use <c>genkernel&nbsp;--udev&nbsp;all</c>.
196 </p>
197
198 <p>
199 Genkernel users will need to <c>emerge&nbsp;coldplug</c> and
200 <c>rc-update&nbsp;add&nbsp;coldplug&nbsp;default</c>.

206 <title>Configuring the System</title>
207 <body>
208
209 <p>
210 Edit your <path>/etc/fstab</path>; an example follows:
211 </p>
212
213 <pre caption="Example fstab">
214 /dev/hda1 /boot ext2 defaults,noatime 1 2
215 /dev/hda2 none swap sw 0 0
216 /dev/hda3 / ext3 noatime 0 1
217 none /proc proc defaults 0 0
218 none /dev/shm tmpfs nodev,nosuid,noexec 0 0
219 /dev/cdroms/cdrom0 /mnt/cdrom auto noauto,user 0 0
220 </pre>
221
222 <p>
223 Edit <path>/etc/conf.d/hostname</path> and <path>/etc/conf.d/domainname</path>,
224 run <c>rc-update&nbsp;add&nbsp;domainname&nbsp;default</c> and edit
225 <path>/etc/conf.d/net</path> and <path>/etc/resolv.conf</path> to configure your network. Add the <c>net.eth0</c>
226 initscript to the default runlevel. If you have multiple NICs, symlink them
227 to the <c>net.eth0</c> init script and add them to the default runlevel as well.
228 </p>
229
230 <p>
231 Edit <path>/etc/hosts</path>; examples are given below:
232 </p>

246 Emerge <c>pcmcia-cs</c> and add it to the default runlevel if you need it.
247 </p>
248
249 <p>
250 Set the root password using <c>passwd</c>.
251 </p>
252
253 <p>
254 Set the necessary system configuration in <path>/etc/rc.conf</path>,
255 <path>/etc/conf.d/rc</path>, <path>/etc/conf.d/keymaps</path>,
256 <path>/etc/conf.d/clock</path>.

267 <c>emerge&nbsp;devfsd</c>.
268 </p>
269
270 <p>
271 Install a system logger like <c>syslog-ng</c> and add it to the default
272 run level. Do the same for a cron daemon like <c>vixie-cron</c> (optional).
273 </p>
274
275 <p>
276 Install the necessary file system tools (<c>xfsprogs</c>, <c>reiserfsprogs</c>
277 or <c>jfsutils</c>) and networking tools (<c>dhcpcd</c> or <c>rp-pppoe</c>).
