linux添加只讀用戶

useradd -s /bin/bash reader

這步不要指定rbash，否側cd等內建命令無法使用

#3.修改用戶密碼

passwd test

#4.創建用戶shell執行命令目錄

mkdir /home/test/.bin

#5.root修改用戶的shell配置文件

chown root. /home/reader/.bash_profile
chmod 755 /home/reader/.bash_profile

#6.修改bash配置文件，主要是指定PATH的讀取

復制代碼
vi /home/reader/.bash_profile

.bash_profile

#Get the aliases and functions

if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

#User specific environment and startup programs

#PATH=P A T H : PATH:PATH:HOME/bin
PATH=$HOME/.bin

export PATH

 

#切換到只讀賬號使環境變量生效
su - reader
source /home/reader/.bash_profile
復制代碼

#7.將允許執行的命令鏈接到$HOME/.bin目錄

復制代碼
ln -s /usr/bin/wc /home/reader/.bin/wc
ln -s /usr/bin/tail /home/reader/.bin/tail
ln -s /bin/more /home/reader/.bin/more
ln -s /bin/cat /home/reader/.bin/cat
ln -s /bin/grep /home/reader/.bin/grep
ln -s /bin/find /home/reader/.bin/find
ln -s /bin/pwd /home/reader/.bin/pwd
ln -s /bin/ls /home/reader/.bin/ls
ln -s /bin/less /home/reader/.bin/less
ln -s /bin/tar /home/reader/.bin/tar
