检测jdk安装包
[hadoop@master ~]$ rpm -qa | grep java``python-javapackages-3.4.1-11.el7.noarch``javapackages-tools-3.4.1-11.el7.noarch``tzdata-java-2019b-1.el7.noarch``java-1.8.0-openjdk-headless-1.8.0.222.b03-1.el7.x86_64``java-1.8.0-openjdk-1.8.0.222.b03-1.el7.x86_64``[hadoop@master ~]$

上传安装介质并解压
[hadoop@master ~]$ ``sudo` `tar` `-xzf jdk-8u191-linux-x64.``tar``.gz -C ``/usr/lib/jvm
设置环境变量,在/etc/profile最前面加上
export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_191``export JRE_HOME=${JAVA_HOME}/jre``export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib``export PATH=${JAVA_HOME}/bin:$PATH
最后生效一下source /etc/profile
