CentOS7 不接受 visudo 更改

CentOS7 不接受 visudo 更改

這是我的 sudoers 文件。我正在使用 sudo visudo 訪問它。我已經添加了這個新用戶'使用者' 然後登出/登入回系統,但該使用者仍需要密碼才能執行 sudo 命令。

## Next comes the main part: which users can run what software on
## which machines (the sudoers file can be shared between multiple
## systems).
## Syntax:
##
##      user    MACHINE=COMMANDS
##
## The COMMANDS section may have other options added to it.
##
## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL
user    ALL=(ALL)       NOPASSWD: ALL

## Allows members of the 'sys' group to run networking, software,
## service management apps and more.
# %sys ALL = NETWORKING, SOFTWARE, SERVICES, STORAGE, DELEGATING, PROCESSES, LOCATE, DRIVERS

## Allows people in group wheel to run all commands
%wheel  ALL=(ALL)       ALL

## Same thing without a password
# %wheel        ALL=(ALL)       NOPASSWD: ALL

## Allows members of the users group to mount and unmount the
## cdrom as root
# %users  ALL=/sbin/mount /mnt/cdrom, /sbin/umount /mnt/cdrom

## Allows members of the users group to shutdown this system
# %users  localhost=/sbin/shutdown -h now

## Read drop-in files from /etc/sudoers.d (the # here does not mean a comment)
#includedir /etc/sudoers.d

由於 visudo 檔案的建構和順序,並且當您確認使用者是「wheel」群組的成員時 - visudo 檔案應用最後的適用權限。

所以你設定用戶沒有密碼。

但是,wheel 群組(使用者是其中的成員)需要密碼。此設定獲勝,因為這是在您告訴用戶不使用密碼之後設定的。

如果您希望用戶沒有密碼來運行 sudo:

  • 放在user ALL=(ALL) NOPASSWD: ALL這條線下方%wheel ALL=(ALL) ALL
  • 從「wheel」群組中刪除使用者。
