# General Setup
|
|
|
|
## Follow the Gentoo Handbook for installing Gentoo
|
|
|
|
[Gentoo Handbook](http://www.gentoo.org/doc/en/handbook/)
|
|
|
|
Generally, you can just use the amd64 version of Gentoo, as most servers now are 64-bit compatible
|
|
|
|
[amd64 handbook](http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml)
|
|
|
|
1. When getting the two tarballs for stage3 and portage, I recommend first retrieving the tarball, then retrieving portage, before extracting either. This way you only have to use links once.
|
|
|
|
1. run `links http://www.gentoo.org/main/en/mirrors.xml`
|
|
2. Go to releases -> amd64 -> autobuilds and select an appropriate stage3. Hardened is recommended for a server.
|
|
3. Go up until you reach the first mirror directory. Go to the `snapshots` folder and download `portage-latest.tar.bz2`
|
|
4. Extract the stage3 tarball : `tar xvjpf stage3-*.tar.bz2`
|
|
5. Extract portage `tar xvjf /mnt/gentoo/portage-latest.tar.bz2 -C /mnt/gentoo/usr`
|
|
|
|
|
|
|
|
2. In your `/etc/make.conf` file, I recommend the following for [compile options](http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?part=1&chap=5#doc_chap4):
|
|
* `CFLAGS="-0s -pipe -march=native -pthread""`
|
|
* Set the MAKEOPTS property to 2x the number of processors/cores, eg, dual core would be `MAKEOPTS="-j4"`
|
|
|
|
3. [Set your profile](http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?part=1&chap=6#doc_chap2) to a server profile, optionally, set it to a hardened server profile.
|
|
4. Compile the kernel using [genkernel](http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?part=1&chap=7#doc_chap4), as it's less involved than manually configuring everything for the kernel.

|
### Install LLVM/Clang (Optional)
|
|
|
|
Clang is a faster compiler than the default GCC. It produces binary as fast, or faster than GCC. To set up clang,
|
|
|
|
run `emerge llvm clang`
|
|
|
|
and add these to lines to the top of your `/etc/make.conf` file
|
|
|
|
CC=/usr/bin/clang
|
|
CXX=/usr/bin/clang++
|
|
|
|
If a package fails to compile with clang, you can comment out those lines, and recompile the package with GCC.
