配置jdk

下载地址http://www.oracle.com/technetwork/java/javase/downloads下载x86 64位的二进制包如：jdk-8u111-linux-x64.tar.gz

解压到到/usr/java下

[root@localhost src]# tar -zxvf jdk-8u111-linux-x64.tar.gz -C /usr/java/[root@localhost java]# lsjdk1.8.0_111

修改/etc/profile文件，修改环境变量

vim /etc/profile

#javaexport JAVA_HOME=/usr/java/jdk1.8.0_111export JRE_HOME=/usr/java/jdk1.8.0_111/jreexport CLASSPATH=/usr/java/jdk1.8.0_111/lib:/usr/java/jdk1.8.0_111/jre/libexport PATH=/usr/java/jdk1.8.0_111/bin:$PATH

重新加载配置文件，并验证

[root@localhost java]# source /etc/profile[root@localhost java]# java -versionjava version "1.8.0_111"Java(TM) SE Runtime Environment (build 1.8.0_111-b14)Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)
