ubuntu14.04 sudoers syntax error?

Question

为什么添加某个用户sudo 不要密码

#
# 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

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

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

#cqe     ALL=ALL  NOPASSWD:ALL

# See sudoers(5) for more information on "#include" directives


#includedir /etc/sudoers.d

结果这个样子还是报错：

>>> /etc/sudoers: syntax error near line 9 <<<
>>> /etc/sudoers: syntax error near line 9 <<<
>>> /etc/sudoers: syntax error near line 11 <<<
>>> /etc/sudoers: syntax error near line 12 <<<

>>> /etc/sudoers: syntax error near line 22 <<<
>>> /etc/sudoers: syntax error near line 22 <<<

这倒底是什么问题呀？
我应该怎么改呀？

你想要的不是允许 sudo 组的用户能够 sudo 任何命令，而是允许 user1 用户如此。

而且根据 /etc/sudoers 文件的提示，我们必须执行 sudo visudo 命令来修改它。

在 %admin 后增加一行，内容如下：

user1    ALL=(ALL)    NOPASSWD:ALL

然后执行 sudo usermod -aG admin user1 将其加入 admin 组。

其实我们可以通过 echo <password> | sudo -S <command> 来让我们的某个命令无需交互密码。
