1.下载jdk-1.8.0 http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html 2.上传到/tmp下 3.在/usr/local/新建java目录 mkdir -p /usr/local/java/ 1. tar -xvf /tmp/jdk-1.8.0 -C /usr/local/java/ 2. 设置环境变量

vi /etc/profile # set environment JAVA_HOME=/usr/java/jdk1.7 #这里要根据自己创建的java路径做相应的修改，不可盲目粘贴复制 CLASSPATH=$JAVA_HOME/lib/ PATH=$PATH:$JAVA_HOME/bin export PATH JAVA_HOME CLASSPATH

3.刷新环境变量

source /etc/profile
