Install JDK under ubuntu16.04

       I have recently installed the environment, and I often do this repeatedly. It is a pity that the DOCKER environment has not been fully deployed and promoted. If the DOCKER suit is done well in the future, there will be no need to engage in these mechanical labors!

decompress

#tar zxvf jdk-8u91-linux-x64.tar.gz

Move the package to /usr/local/java

#mv jdk1.8_91 /usr/local/java/jdk1.8_91

Edit the linux configuration file

#vi ~ / .bashrc

export JAVA_HOME=/usr/local/java/jdk1.8.0_91
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

 

If you encounter vi prompt  :set noreadonly to unset the readonly flag.

Just :set noreadonly

 

Make the configuration take effect

#source  ~/.bashrc

verify

#java -version

java version "1.8.0_91"

Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
