安装JDK

下载JDK:

– 官网 http://www.oracle.com/technetwork/java/javase/downloads/
– 目前最新版为 Java SE Development Kit 8u91

解压，移动到/usr中

[root@localhost ~]# wget http://download.oracle.com/otn-pub/java/jdk/8u91-b14/jdk-8u91-linux-x64.tar.gz
[root@localhost ~]# tar -zxvf jdk-8u91-linux-x64.tar.gz
[root@localhost ~]# mv jdk1.8.0_91 /usr/local/jdk/

添加环境变量 【在文件最后加上如下几行：若已存在PATH，则合并】

[root@localhost ~]# gedit /etc/profile

export JAVA_HOME=/usr/local/jdk/
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export CLASSPATH=$CLASSPATH:.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

更改默认配置选项 ,依次执行如下命令

update-alternatives --install /usr/bin/java java /usr/local/jdk/bin/java 300 update-alternatives --install /usr/bin/javac javac /usr/local/jdk/bin/javac 300 update-alternatives --install /usr/bin/jar jar /usr/local/jdk/bin/jar 300 update-alternatives --install /usr/bin/javah javah /usr/local/jdk/bin/javah 300 update-alternatives --install /usr/bin/javap javap /usr/local/jdk/bin/javap 300
