悔过书一下系统中的jdk版本

上传安设介质并解压

[hadoop@master ~]$ sudo tar -xzf jdk-8u191-linux-x64.tar.gz -C /usr/lib/jvm

设立环境日定量,在/etc/profile最之前加上

export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_191export JRE_HOME=${JAVA_HOME}/jreexport CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/libexport PATH=${JAVA_HOME}/bin:$PATH

结尾奏效一下source /etc/profile
