# Chapter 9 - System Configuration
|
||||
## Sections 9.1 - System V Init
|
||||
This section describes the system init that LFS, the tasks it makes to complete the boot process, and various run levels.
|
||||
## Section 9.2 - LFS Init Scripts
|
||||
LFS comes with some pre-configured scripts that work with this init process at boot time.
|
||||
> Installed scripts:
|
||||
> checkfs, cleanfs, console, functions, halt, ifdown, ifup, localnet, modules, mountfs, mountvirtfs, network, rc, reboot, sendsignals, setclock, ipv4-static, swap, sysctl, sysklogd, template, udev, and udev_retry
|
||||
> Installed directories:
|
||||
> /etc/rc.d, /etc/init.d (symbolic link), /etc/sysconfig, /lib/services, /lib/lsb (symbolic link)
|
||||
This has its own sources, and is installed with `make`.
|
||||
```
|
||||
make install
|
||||
```
|
||||
## Section 9.3 - Device and Kernel Modules
|
||||
Just light reading ...
|
||||
## Section 9.4 - Setting Up for Devices
|
||||
Create rules for naming network devices.
|
||||
```
|
||||
bash /usr/lib/udev/init-net-rules.sh
|
||||
```
|
||||
## Section 9.5 - General Network Configuration
|
||||
We need to setup the anticipated network interface.
|
||||
```
|
||||
cd /etc/sysconfig/
|
||||
cat > ifconfig.eth0 << "EOF"
|
||||
ONBOOT=yes
|
||||
IFACE=eth0
|
||||
SERVICE=ipv4-static
|
||||
IP=192.168.2.250
|
||||
GATEWAY=192.168.2.1
|
||||
PREFIX=24
|
||||
BROADCAST=192.168.2.255
|
||||
EOF
|
||||
```
|
||||
Create our `resolve.conf` file,
|
||||
```
|
||||
cat > /etc/resolv.conf << "EOF"
|
||||
# Begin /etc/resolv.conf
|
||||
|
||||
domain home.lan
|
||||
nameserver 192.168.2.22
|
||||
nameserver 192.168.2.1
|
||||
|
||||
# End /etc/resolv.conf
|
||||
EOF
|
||||
```
|
||||
our hostname,
|
||||
```
|
||||
echo lfs > /etc/hostname
|
||||
```
|
||||
and also our `hosts` file,
|
||||
```
|
||||
cat > /etc/hosts << "EOF"
|
||||
# Begin /etc/hosts
|
||||
|
||||
127.0.0.1 localhost.localdomain localhost
|
||||
127.0.1.1 lfs.home.lan lfs
|
||||
::1 localhost ip6-localhost ip6-loopback
|
||||
ff02::1 ip6-allnodes
|
||||
ff02::2 ip6-allrouters
|
||||
|
||||
# End /etc/hosts
|
||||
EOF
|
||||
```
|
||||
## Section 9.6 - Bootscript Usage and Configuration
|
||||
We need to configure SysVinit
|
||||
```
|
||||
cat > /etc/inittab << "EOF"
|
||||
# Begin /etc/inittab
|
||||
|
||||
id:3:initdefault:
|
||||

|

6:2345:respawn:/sbin/agetty tty6 9600
|
||||
|
||||
# End /etc/inittab
|
||||
EOF
|
||||
```
|
||||
setting the system clock,
|
||||
```
|
||||
cat > /etc/sysconfig/clock << "EOF"
|
||||
# Begin /etc/sysconfig/clock
|
||||
|
||||
UTC=1
|
||||
|
||||
# Set this to any options you might need to give to hwclock,
|
||||
# such as machine hardware clock type for Alphas.
|
||||
CLOCKPARAMS=
|
||||
|
||||
# End /etc/sysconfig/clock
|
||||
EOF
|
||||
```
|
||||
and configuring the console.
|
||||
```
|
||||
cat > /etc/sysconfig/console << "EOF"
|
||||
# Begin /etc/sysconfig/console
|
||||
|
||||
UNICODE="1"
|
||||
FONT="Lat2-Terminus16"
|
||||
|
||||
# End /etc/sysconfig/console
|
||||
EOF
|
||||
```
|
||||
## Section 9.7 - Configuring Locale
|
||||
This locale stuff seems really annoying .. but it's necessary. These commands use glibc to determine locale information.
|
||||
```
|
||||
LC_ALL=en_US locale language
|
||||
LC_ALL=en_US locale charmap
|
||||
LC_ALL=en_US locale int_curr_symbol
|
||||
LC_ALL=en_US locale int_prefix
|
||||
```
|
||||
Which can be used in our bash profile,
|
||||
```
|
||||
cat > /etc/profile << "EOF"
|
||||
# Begin /etc/profile
|
||||
|
||||
for i in $(locale); do
|
||||
unset ${i%=*}
|
||||
done
|
||||
|
||||
if [[ "$TERM" = linux ]]; then
|
||||
export LANG=C.UTF-8
|
||||
else
|
||||
export LANG=en_US.ISO-8859-1
|
||||
fi
|
||||
|
||||
# End /etc/profile
|
||||
EOF
|
||||
```
|
||||
## Section 9.8 - Readline's `etc/inputrc/ File
|
||||
This file is needed to support shells, such as `bash`, interpret keyboard input.
|
||||
```
|
||||
cat > /etc/inputrc << "EOF"
|
||||
# Begin /etc/inputrc
|
||||
# Modified by Chris Lynn <roryo@roryo.dynup.net>
|
||||
|
||||
# Allow the command prompt to wrap to the next line
|
||||
set horizontal-scroll-mode Off
|
||||
|
||||
# Enable 8-bit input
|
||||
set meta-flag On
|
||||
set input-meta On
|
||||
|
||||
# Turns off 8th bit stripping
|
||||
set convert-meta Off
|
||||
|
||||
# Keep the 8th bit for display
|
||||
set output-meta On
|
||||
|
||||
# none, visible or audible
|
||||
set bell-style none
|
||||
|
||||
# All of the following map the escape sequence of the value
|
||||
# contained in the 1st argument to the readline specific functions
|
||||
"\eOd": backward-word
|
||||
"\eOc": forward-word
|
||||
|
||||
# for linux console
|
||||
"\e[1~": beginning-of-line
|
||||
"\e[4~": end-of-line
|
||||
"\e[5~": beginning-of-history
|
||||
"\e[6~": end-of-history
|
||||
"\e[3~": delete-char
|
||||
"\e[2~": quoted-insert
|
||||
|
||||
# for xterm
|
||||
"\eOH": beginning-of-line
|
||||
"\eOF": end-of-line
|
||||
|
||||
# for Konsole
|
||||
"\e[H": beginning-of-line
|
||||
"\e[F": end-of-line
|
||||
|
||||
# End /etc/inputrc
|
||||
EOF
|
||||
```
|
||||
## Seciton 9.9 - Set Options for Shells
|
||||
This shells available on the system must be identified.
|
||||
```
|
||||
cat > /etc/shells << "EOF"
|
||||
# Begin /etc/shells
|
||||
|
||||
/bin/sh
|
||||
/bin/bash
|
||||
|
||||
# End /etc/shells
|
||||
EOF
|
||||
```
