记录blfs书籍前几个章节的配置内容。

bash shell启动文件章节

1.切换root用户

su

2.创建/etc/profile文件

cat > /etc/profile << "EOF"

# Begin /etc/profile

# Written for Beyond Linux From Scratch

# by James Robertson <jameswrobertson@earthlink.net>

# modifications by Dagmar d'Surreal <rivyqntzne@pbzpnfg.arg>

# System wide environment variables and startup programs.

# System wide aliases and functions should go in /etc/bashrc.  Personal

# environment variables and startup programs should go into

# ~/.bash_profile.  Personal aliases and functions should go into

# ~/.bashrc.

# Functions to help us manage paths.  Second argument is the name of the

# path variable to be modified (default: PATH)

pathremove () {

        local IFS=':'

        local NEWPATH

        local DIR

        local PATHVARIABLE=${:-PATH}

        for DIR in ${!PATHVARIABLE} ; do

                if [ "$DIR" != "$1" ] ; then

                  NEWPATH=${NEWPATH:+$NEWPATH:}$DIR

                fi

        done

        export $PATHVARIABLE="$NEWPATH"

}

pathprepend () {

        pathremove $ $

        local PATHVARIABLE=${:-PATH}

        export $PATHVARIABLE="$1${!PATHVARIABLE:+:${!PATHVARIABLE}}"

}

pathappend () {

        pathremove $ $

        local PATHVARIABLE=${:-PATH}

        export $PATHVARIABLE="${!PATHVARIABLE:+${!PATHVARIABLE}:}$1"

}

export -f pathremove pathprepend pathappend

# Set the initial path

export PATH=/bin:/usr/bin

if [ $EUID -eq  ] ; then

        pathappend /sbin:/usr/sbin

        unset HISTFILE

fi

# Setup some environment variables.

export HISTSIZE=

export HISTIGNORE="&:[bf]g:exit"

# Set some defaults for graphical systems

export XDG_DATA_DIRS=${XDG_DATA_DIRS:-/usr/share/}

export XDG_CONFIG_DIRS=${XDG_CONFIG_DIRS:-/etc/xdg/}

export XDG_RUNTIME_DIR=${XDG_RUNTIME_DIR:-/tmp/xdg-$USER}

# Setup a red prompt for root and a green one for users.

NORMAL="\[\e[0m\]"

RED="\[\e[1;31m\]"

GREEN="\[\e[1;32m\]"

if [[ $EUID ==  ]] ; then

  PS1="$RED\u [ $NORMAL\w$RED ]# $NORMAL"

else

  PS1="$GREEN\u [ $NORMAL\w$GREEN ]\$ $NORMAL"

fi

for script in /etc/profile.d/*.sh ; do

        if [ -r $script ] ; then

                . $script

        fi

done

unset script RED GREEN NORMAL

# End /etc/profile

EOF

3.创建/etc/profile.d 放置各个初始化脚本的目录

install --directory --mode= --owner=root --group=root /etc/profile.d

4.创建/etc/profile.d/bash_completion.sh脚本

cat > /etc/profile.d/bash_completion.sh << "EOF"

# Begin /etc/profile.d/bash_completion.sh

# Import bash completion scripts

for script in /etc/bash_completion.d/*.sh ; do

        if [ -r $script ] ; then

                . $script

        fi

done

# End /etc/profile.d/bash_completion.sh

EOF

5.确保该目录存在

install --directory --mode= --owner=root --group=root /etc/bash_completion.d

6.创建/etc/profile.d/dircolors.sh脚本

cat > /etc/profile.d/dircolors.sh << "EOF"

# Setup for /bin/ls and /bin/grep to support color, the alias is in /etc/bashrc.

if [ -f "/etc/dircolors" ] ; then

        eval $(dircolors -b /etc/dircolors)

fi

if [ -f "$HOME/.dircolors" ] ; then

        eval $(dircolors -b $HOME/.dircolors)

fi

alias ls='ls --color=auto'

alias grep='grep --color=auto'

EOF

7.创建/etc/profile.d/extrapaths.sh脚本

cat > /etc/profile.d/extrapaths.sh << "EOF"

if [ -d /usr/local/lib/pkgconfig ] ; then

        pathappend /usr/local/lib/pkgconfig PKG_CONFIG_PATH

fi

if [ -d /usr/local/bin ]; then

        pathprepend /usr/local/bin

fi

if [ -d /usr/local/sbin -a $EUID -eq  ]; then

        pathprepend /usr/local/sbin

fi

# Set some defaults before other applications add to these paths.

pathappend /usr/share/man  MANPATH

pathappend /usr/share/info INFOPATH

EOF

8.创建/etc/profile.d/readline.sh脚本

cat > /etc/profile.d/readline.sh << "EOF"

# Setup the INPUTRC environment variable.

if [ -z "$INPUTRC" -a ! -f "$HOME/.inputrc" ] ; then

        INPUTRC=/etc/inputrc

fi

export INPUTRC

EOF

9.创建/etc/profile.d/umask.sh脚本

cat > /etc/profile.d/umask.sh << "EOF"

# By default, the umask should be set.

if [ "$(id -gn)" = "$(id -un)" -a $EUID -gt  ] ; then

  umask

else

  umask

fi

EOF

10.创建用于语言支持的脚本

cat > /etc/profile.d/i18n.sh << "EOF"

# Set up i18n variables

export LANG=en_US.utf8

EOF

11.创建/etc/bashrc文件

cat > /etc/bashrc << "EOF"

# Begin /etc/bashrc

# Written for Beyond Linux From Scratch

# by James Robertson <jameswrobertson@earthlink.net>

# updated by Bruce Dubbs <bdubbs@linuxfromscratch.org>

# System wide aliases and functions.

# System wide environment variables and startup programs should go into

# /etc/profile.  Personal environment variables and startup programs

# should go into ~/.bash_profile.  Personal aliases and functions should

# go into ~/.bashrc

# Provides colored /bin/ls and /bin/grep commands.  Used in conjunction

# with code in /etc/profile.

alias ls='ls --color=auto'

alias grep='grep --color=auto'

# Provides prompt for non-login shells, specifically shells started

# in the X environment. [Review the LFS archive thread titled

# PS1 Environment Variable for a great case study behind this script

# addendum.]

NORMAL="\[\e[0m\]"

RED="\[\e[1;31m\]"

GREEN="\[\e[1;32m\]"

if [[ $EUID ==  ]] ; then

  PS1="$RED\u [ $NORMAL\w$RED ]# $NORMAL"

else

  PS1="$GREEN\u [ $NORMAL\w$GREEN ]\$ $NORMAL"

fi

unset RED GREEN NORMAL

# End /etc/bashrc

EOF

12.创建/etc/ske目录

mkdir /etc/ske

13.创建/etc/skel/.bash_profile配置文件

cat > /etc/skel/.bash_profile << "EOF"

# Begin ~/.bash_profile

# Written for Beyond Linux From Scratch

# by James Robertson <jameswrobertson@earthlink.net>

# updated by Bruce Dubbs <bdubbs@linuxfromscratch.org>

# Personal environment variables and startup programs.

# Personal aliases and functions should go in ~/.bashrc.  System wide

# environment variables and startup programs are in /etc/profile.

# System wide aliases and functions are in /etc/bashrc.

if [ -f "$HOME/.bashrc" ] ; then

  source $HOME/.bashrc

fi

if [ -d "$HOME/bin" ] ; then

  pathprepend $HOME/bin

fi

# Having . in the PATH is dangerous

#if [ $EUID -gt 99 ]; then

#  pathappend .

#fi

# End /etc/skel/.bash_profile

EOF

14.创建/etc/skel/.profile配置文件

cat > /etc/skel/.profile << "EOF"

# Begin ~/.profile

# Personal environment variables and startup programs.

if [ -d "$HOME/bin" ] ; then

  pathprepend $HOME/bin

fi

# Set up user specific i18n variables

#export LANG=<ll>_<CC>.<charmap><@modifiers>

# End /etc/skel/.profile

EOF

15.创建/etc/skel/.bashrc文件

cat > /etc/skel/.bashrc << "EOF"

# Begin ~/.bashrc

# Written for Beyond Linux From Scratch

# by James Robertson <jameswrobertson@earthlink.net>

# Personal aliases and functions.

# Personal environment variables and startup programs should go in

# ~/.bash_profile.  System wide environment variables and startup

# programs are in /etc/profile.  System wide aliases and functions are

# in /etc/bashrc.

if [ -f "/etc/bashrc" ] ; then

  source /etc/bashrc

fi

# Set up user specific i18n variables

#export LANG=<ll>_<CC>.<charmap><@modifiers>

# End /etc/skel/.bashrc

EOF

16.创建/etc/skel/.bash_logout文件

cat > /etc/skel/.bash_logout << "EOF"

# Begin ~/.bash_logout

# Written for Beyond Linux From Scratch

# by James Robertson <jameswrobertson@earthlink.net>

# Personal items to perform on logout.

# End /etc/skel/.bash_logout

EOF

17.复制配置文件至root用户下

cp /etc/skel/.* ~/

18.创建/etc/dircolors文件

dircolors -p > /etc/dircolors

19.创建/etc/issue文件内容自定义，下面贴出书中反斜杠后每个字符的意义

sudo vim /etc/issue

b             插入当前行的波特率。

d             插入当前日期。

s             插入系统名，操作系统的名称。

l             插入当前tty行名称。

m             插入机器的架构标识符，如i686。

n             插入机器的节点名，也就是主机名。

o             插入机器的域名。

r             插入内核的版本号，例如2.6.11.。

t             插入当前时间。

u             插入当前登录的用户数量。

U             插入字符串“ user”或“<n> users”，其中<n>为当前登录的用户数量。

v             插入操作系统的版本，例如，构建日期等。

我的配置文件内容

Welcome to login! \s (\l)

20.安装blfs脚本中的random脚本

make install-random

21.下载lsb_releas包并校验md5

# wget https://downloads.sourceforge.net/lsb/lsb-release-1.4.tar.gz

md5sum -c md5sums

解压并进入lsb_releas包

#tar -xvf lsb-release-1.4.tar.gz

cd lsb-release-1.4

参照书中说明编译安装

sed -i "s|n/a|unavailable|" lsb_release

./help2man -N --include ./lsb_release.examples \

              --alt_version_key=program_version ./lsb_release > lsb_release.

su

install -v -m  lsb_release. /usr/share/man/man1 &&

install -v -m  lsb_release   /usr/bin

返回blfs-sources目录并删除解压包目录

cd /sources/blfs-sources/

rm -rf lsb-release-1.4

22.创建用户并设置密码

useradd -m <newuser>

passwd <newuser>

23.全部配置完重启

reboot
