添加环境变量:

 

export JAVA_HOME=/evir/jdk8/jdk1.8.0_144
export classpath=.$JAVA_HOME/lib
export PATH=$PATH:$JAVA_HOME/bin

 

 jdk包:

 

 

 

 

 

安装目录:

# /etc/profile

# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc

# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.
