1. yum install java-1.8.0-openjdk java-1.8.0-openjdk-devel (这样安装的jdk目录在/usr/lib/jvm)
2. 为了规范进入/usr/lib/jvm mv java /usr/local/jdk1.8
3. 配置环境变量vi /etc/profile 在文件最后加入如下行

#set java environment  
JAVA_HOME=/usr/local/jdk1.8
PATH=$PATH:$JAVA_HOME/bin  
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/jre/lib/rt.jar
export JAVA_HOME  CLASSPATH  PATH  

3. 执行如下命令使设置生效
