当在终端执行sudo命令时，系统提示“cuser is not in the sudoers file”：

具体报错信息为：

-bash-4.1$ sudo vim /etc/profileWe trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:#1) Respect the privacy of others.#2) Think before you type.#3) With great power comes great responsibility.[sudo] password for hadoop:
hadoop is not in the sudoers file.  This incident will be reported.

其实就是没有权限进行sudo，解决方法如下（这里假设用户名是hadoop）：

1.切换到root用户：$ su

2.打开/etc/sudoers文件：$vim /etc/sudoers

3.修改文件内容：

找到“root ALL=(ALL) ALL”一行，在下面插入新的一行，内容是“hadoop ALL=(ALL) ALL”，

然后在vim键入命令“wq!”保存并退出。

注：这个文件是只读的，不加“!”保存会失败。

4.退出root用户：$ exit
