Ubuntu 提示sudo: XXX: command not found解决办法（以java为例）

ubuntu下运行sudo Java 时提示“sudo: java: command not found”。在网上找了，其中很多方法都提示要修改/etc/profile的配置，或是修改/etc/environment的配置。配置完sudo java就可以运行了，但是改完之后依然无效。

根据一个大神的指引，应该是修改/etc/sudoers这个文件，

sudo vim /etc/sudoers

显示内容如下：

#
# 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:/snap/bin:/usr/java/jdk1.8.0_131/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
 
# See sudoers(5) for more information on "#include" directives:
 
#includedir /etc/sudoers.d

在Defaults secure_path 中添加Java的路径,:/usr/java/jdk1.8.0_131/bin,不同软件路径以“:”为间隔

再次运行 sudo java 就可以使用了。
