wget  http://apache.fayea.com/hadoop/common/hadoop-2.7.2/hadoop-2.7.2.tar.gz

java安装

wget -c --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-i586.rpm

wget -c --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.rpm

挺有意思，这个wget地址用百度查了半个小时没解决，用Google1分钟不到，第一个链接，搞定。Stack Overflow真的很吊。

下载完成之后

执行：rpm -ivh jdk-8u131-linux-i586.rpm

然后在 etc的profile 文件的末未添加：

#set java environment

JAVA_HOME=/usr/java/default

JRE_HOME=/usr/java/default/jre

PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin

wq保存
