Question

当我尝试在笔记本电脑上使用sudo时，它说

sudo: /etc/sudoers is owned by uid 502, should be 0
sudo: no valid sudoers sources found, quitting

由于我最近手动编辑了文件，我想将其重置为默认值。 root用户和admin作为sudoer，没有其他人的情况怎么样？请提供整个文件！

编辑：好的，我重置了文件。我仍然得到错误。我该如何解决这个问题？

Answer 1

我正在运行OS X 10.10.2（14C109）。这是我sudoers文件的全部内容，我从未编辑过该文件：

# sudoers file.
#
# This file MUST be edited with the 'visudo' command as root.
# Failure to use 'visudo' may result in syntax or file permission errors
# that prevent sudo from running.
#
# See the sudoers man page for the details on how to write a sudoers file.
#

# Host alias specification

# User alias specification

# Cmnd alias specification

# Defaults specification
Defaults    env_reset
Defaults    env_keep += "BLOCKSIZE"
Defaults    env_keep += "COLORFGBG COLORTERM"
Defaults    env_keep += "__CF_USER_TEXT_ENCODING"
Defaults    env_keep += "CHARSET LANG LANGUAGE LC_ALL LC_COLLATE LC_CTYPE"
Defaults    env_keep += "LC_MESSAGES LC_MONETARY LC_NUMERIC LC_TIME"
Defaults    env_keep += "LINES COLUMNS"
Defaults    env_keep += "LSCOLORS"
Defaults    env_keep += "SSH_AUTH_SOCK"
Defaults    env_keep += "TZ"
Defaults    env_keep += "DISPLAY XAUTHORIZATION XAUTHORITY"
Defaults    env_keep += "EDITOR VISUAL"
Defaults    env_keep += "HOME MAIL"

# Runas alias specification

# User privilege specification
root    ALL=(ALL) ALL
%admin  ALL=(ALL) ALL

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

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

# Samples
# %users  ALL=/sbin/mount /cdrom,/sbin/umount /cdrom
# %users  localhost=/sbin/shutdown -h now

ETA：听起来您可能在不使用visudo的情况下编辑了此文件，并且权限搞砸了。 UID 502意味着您拥有该文件，而不是root，因此sudo感到困惑和纾困。

编辑完文件后，您应该以root身份运行chown root /etc/sudoers或chmod 440 /etc/sudoers以恢复文件的正确权限。

这是默认的

要修复sudoers文件的权限，您可以运行以下命令：

sudo chown root:wheel /etc/sudoers
sudo chmod 440 /etc/sudoers

此外，您还可以运行＆＃34;修复磁盘权限＆＃34;在“磁盘工具”中，选择左侧栏上的磁盘驱动器，然后转到“急救”选项卡。

OS X Yosemite上的sudoers文件的默认值是多少？
