上傳安裝介質并解壓
[hadoop@master ~]$ sudo tar -xzf jdk-8u191-linux-x64.tar.gz -C /usr/lib/jvm
設置環境變量,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
