Linux系統下誤刪除文件怎么辦

  服務器誤刪了/usr/bin和/usr/sbin目錄,然后,從別的地方拷貝這兩個目錄過來,發現可能很多是鏈接等非普通文件,可拷貝的時候對鏈接的處理不知道應加什么參數,所以,一百多兆的東西拷貝了近一個G;最后,先給tar了一下,在拷貝。

  這樣,服務器基本弄好,建議:

  1.不要直接用root登入,特別是不熟悉的人。

  2.建議需要執行root權限命令的使用sudo,少用su;

  3.可用visudo來配置需要執行的root權限命令

  eg: xxx ALL=/sbin/mount,/sbin/unmount,/sbin/ifconfig NOPASSWD: ALL

  rm命令不行;但是,還有“后遺癥”:

  1.登入時,'linux': unknown terminal type;

  2.使用top, clear (知道的)時, 因為 terminal type問題;

  3.vim也是類似問題,不可操作;已解決,但只能用基本模式;

  4.tftp、telnet服務,已解決。
