Linux只读账号配置【转】

整个配置的命令如下(主要使用了:Linux bash受限的shell(RESTRICTED SHELL)

步骤
#1.创建只读shell(这步可以省略)

ln -s /bin/bash  /bin/rbash


#2.创建用户并指定用户启动执行的shell

useradd -s /bin/bash readonly

这步不要指定rbash,否侧cd等內建命令无法使用


#3.修改用户密码

passwd readonly


#4.创建用户shell执行命令目录

mkdir /home/readonly/.bin


#5.root修改用户的shell配置文件

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

并设置文件不可删除权限
chattr -i /home/readonly/.bash_profile

 

#6.将允许执行的命令链接到$HOME/.bin目录

ln -s /usr/bin/wc  /home/readonly/.bin/wc
ln -s /usr/bin/tail  /home/readonly/.bin/tail
ln -s /bin/more  /home/readonly/.bin/more
ln -s /bin/cat  /home/readonly/.bin/cat
ln -s /bin/grep  /home/readonly/.bin/grep
ln -s /bin/find  /home/readonly/.bin/find
ln -s /bin/pwd  /home/readonly/.bin/pwd
ln -s /bin/ls  /home/readonly/.bin/ls
ln -s /usr/bin/less /home/readonly/.bin/less
ln -s /bin/tar  /home/readonly/.bin/tar


#7.修改bash配置文件,主要是指定PATH的读取

vi /home/readonly/.bash_profile 
# .bash_profile
 
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi
 
# User specific environment and startup programs
#PATH=$PATH:$HOME/bin
PATH=$HOME/.bin
export PATH

 

#切换到只读账号使环境变量生效
su - readonly
source /home/readonly/.bash_profile
