Linux记录- Linux下限制rm -rf /
操作说明:
为了防止在linux下执行操作的时候误操作rm -rf /,或者rm -rf 一些比较重要的目录,我们做以下操作来限制rm的删除
1、下载源码安装包
https://raw.githubusercontent.com/bazingafraser/cv/master/article/rm/safe-rm-0.12.tar.gz
2、具体操作如下
[root@i-ekowjial ~] tar -xvzf safe-rm-0.12.tar.gz
[root@i-ekowjial ~] cd safe-rm-0.12
[root@i-ekowjial safe-rm-0.12]# mv safe-rm /usr/local/bin/rm
[root@i-ekowjial safe-rm-0.12]# chown root:root /usr/local/bin/rm
[root@i-ekowjial safe-rm-0.12]# vi /etc/profile
最后一行添加:
PATH=/usr/local/bin:/bin:/usr/bin:$PATH
[root@i-ekowjial safe-rm-0.12]# source /etc/profile 环境变量生效
[root@i-ekowjial safe-rm-0.12]# vim /etc/safe-rm.conf
将禁止删除的目录写入该文件,每个目录一行
/
/boot
/sbin
/data/ccc
保存退出即可
[root@i-ekowjial safe-rm-0.12]#
3、测试
在/data创建一个ccc的目录并写入/etc/safe-rm.conf
保存退出之后删除ccc出现以下返回,证明操作成功
[root@i-ekowjial data]# rm -rf ccc/
safe-rm: skipping ccc/
[root@i-ekowjial data]#
