XXX 用户 is not in the sudoers file. This incident will be reported 的问题解决方案

说的是，这种问题，是出现在ubuntu系统里。

root@SparkSingleNode:/usr/local/jdk# pwd

/usr/local/jdk

root@SparkSingleNode:/usr/local/jdk# su spark

spark@SparkSingleNode:/usr/local/jdk$ sudo cp /home/spark/Downloads/Spark_Cluster_Software/jdk-8u60-linux-x64.tar.gz  /usr/local/jdk

[sudo] password for spark:

spark is not in the sudoers file.  This incident will be reported.

spark@SparkSingleNode:/usr/local/jdk$ ls

解决办法：

1. 切换到root用户下

spark@SparkSingleNode:/usr/local/jdk$ pwd

/usr/local/jdk

spark@SparkSingleNode:/usr/local/jdk$ su root

Password:

root@SparkSingleNode:/usr/local/jdk#

2、/etc/sudoers文件默认是只读的，对root来说也是，因此需先添加sudoers文件的写权限，

命令是:

chmod u+w /etc/sudoers

root@SparkSingleNode:/usr/local/jdk# chmod u+w /etc/sudoers

root@SparkSingleNode:/usr/local/jdk#

3.编辑sudoers文件

vim /etc/sudoers

找到这行 root ALL=(ALL) ALL,在它下面添加xxx ALL=(ALL) ALL (这里的xxx是你的用户名)

ps:这里说下你可以sudoers添加下面四行中任意一条

youuser            ALL=(ALL)                ALL

%youuser           ALL=(ALL)                ALL

youuser            ALL=(ALL)                NOPASSWD: ALL

%youuser           ALL=(ALL)                NOPASSWD: ALL

第一行:允许用户youuser执行sudo命令(需要输入密码).

第二行:允许用户组youuser里面的用户执行sudo命令(需要输入密码).

第三行:允许用户youuser执行sudo命令,并且在执行的时候不输入密码.

第四行:允许用户组youuser里面的用户执行sudo命令,并且在执行的时候不输入密码.

在这里，我就为了方便，选择第四行。日后，生产中，再去修改。

我的用户组是spark，目前spark用户组里的用户只有spark。

Defaults        env_reset

Defaults        mail_badpass

Defaults        secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

root    ALL=(ALL:ALL) ALL

%spark  ALL=(ALL) NOPASSWD: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

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

#includedir /etc/sudoers.d

4.撤销sudoers文件写权限,命令:

chmod u-w /etc/sudoers

这样普通用户就可以使用sudo了.

成功!
