sudoers不知怎么改错了，请教问题出在哪里。

代码:

#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
#
Defaults    env_reset
Defaults    mail_badpass
Defaults    secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

# Host alias specification

# User alias specification

# Cmnd alias specification

# User privilege specification
root    ALL=(ALL:ALL) ALL
yangdawei ALL=(ALL) ALL
# Allow members of group sudo to execute any command
%sudo ALL=(ALL:ALL) ALL
# See sudoers(5) for more information on "#include" directives:

#includedir /etc/sudoers.d

代码:

sudoers的完整内容是:

代码:

#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
#
Defaults env_reset
Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

# Host alias specification

# User alias specification

# Cmnd alias specification

# User privilege specification
root    ALL=(ALL:ALL) ALL
yangdawei ALL=(ALL:ALL) ALL

# Allow members of group sudo to execute any command
%sudo ALL=(ALL:ALL) ALL

然后更新：
source sudoers
报错信息：

代码:

bash: Defaults: command not found
bash: Defaults: command not found
bash: $'\r': command not found
bash: $'\r': command not found
bash: $'\r': command not found
bash: $'\r': command not found
bash: sudoers: line 19: syntax error near unexpected token `('
'ash: sudoers: line 19: `root   ALL=(ALL:ALL) ALL

检查语法：
visudo -c

代码:

>>> /etc/sudoers: syntax error near line 9 <<<
>>> /etc/sudoers: syntax error near line 9 <<<
>>> /etc/sudoers: syntax error near line 9 <<<
>>> /etc/sudoers: syntax error near line 10 <<<

开始尝试用visudo打开看看sudoers，但因来知道其操作方式，操作不当，退出后即出现了上述问题。

此后再尝试修改sudoers就使用vi了。

yangdawei 写道:

source sudoers 报错信息：

sudoers 不是 bash 脚本

引用:

$ help source
source: source filename [arguments] - Execute commands from a file in the current shell.

Ubuntu 出现这种问题是比较难办的。因为默认没有 root 密码，sudoers 损坏就意味着丢失 root 权限。可用 pkexec 提权修复
Debian 问题不大，直接用 su 即可

引用:

sudoers: syntax error near line 9 <<<

这个原因未知，需再研究

可能是文件之外的问题，因为工作需要，重做了系统。这个sudoers不搞清楚了轻易不能碰了。

1. 這是錯誤的操作指令
1-1. 正確指令是
sudo visudo
1-1-1. 不必指名 /etc/sudoers
因為它就專為修改 /etc/sudoers 而設
1-1-1-1. http://manpages.ubuntu.com/manpages/wil ... udo.8.html
visudo — edit the sudoers file

2. 在 Ubuntu 新手對於權限 / uid / gid 不熟悉前
不建議使用 root 登入也不建議切換成 root 身份
2-1. 使用非 root 登入需要 root 權限時加 sudo / gksudo 在指令前面參見
https://help.ubuntu.com/community/RootSudo#Usage
2-2. 如果要給登入的帳號能夠使用 sudo / gksudo 行使 root 的權利
只要把該非 root 使用者帳號使用 usermod 指令加入 sudo 群組即可
http://manpages.ubuntu.com/manpages/wil ... mod.8.html
usermod - modify a user account

3. 抱歉太晚回覆你

4. 以後有需要再參閱
4-1. https://help.ubuntu.com/community/Sudoers
Sudoers
4-2. https://www.digitalocean.com/community/ ... and-centos
How To Edit the Sudoers File on Ubuntu and CentOS
4-3. 再強調新手不熟悉 ubuntu 權限 / uid / gid 前
不建議使用 root 登入也不建議切換成 root 身份
4-4. 也不建議你任意改變 /etc/sudoers 檔案
4-5. 提供前面文章僅僅提供你參考不是鼓勵你現在就動手去改它
