Centos下运行sudo Java 时提示“sudo: java: command not found”。应该是修改/etc/sudoers这个文件，　其他linux系统原理一样。

sudo vim /etc/sudoers

#
# 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/jdk8/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/jdk8/bin

再次运行 sudo java 就可以使用了。
