The root user is prompted with: Operation not permitted
情景还原
笔者今天在使用root用户删除服务器上的一个文件时,被系统告知:Operation not permitted。甚至不能使用chmod给777权限。
一开始我是很懵逼的状态,还有root用户操作不了的东西(原谅作者对Linux不是很深入了解)?
具体如下图所示:
解决方法
上面我们执行的chmod命令,其底层实现是chattr命令,用此命的功能更为强大,甚至可以锁定文件,即使root用户也操作不了此文件。
chattr是用来更改文件属性,lsattr可用来查看文件的属性,执行命令lsattr /webapps/.usr.ini便可以看到当前文件的属性;
可以发现当前文件有个i属性,查阅命令帮助文档可以看到有i属性的文件是不能修改的,更不可被删除,即使是root用户也不可。
既然知道了文件不能删除的原因是加了i属性,所以相应的解决方案就是把文件的i属性去除,然后再删除。

chattr -i webapps //去除i属性
rm -rf webapps //删除文件夹
