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
#6.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=$HOME/.bin export PATH #切换到只读账号使环境变量生效 su - readonly source /home/readonly/.bash_profile #7.将允许执行的命令链接到$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 /bin/less /home/readonly/.bin/less ln -s /bin/tar /home/readonly/.bin/tar
