1.利用SSH工具上传下载好的JDK

cd D:\Program Files\SSH Communications Security\SSH Secure Shell

scp2.exe C:\Users\Administrator\Desktop\jdk-7u75-linux-x64.rpm root@121.41.82.62:/root

Are you sure you want to continue connecting (yes/no)? yes

root@121.41.82.62's password:

2.在Linux端安装jdk

cd /root

chmod +x jdk-7u75-linux-x64.rpm

rpm -ivh jdk-7u75-linux-x64.rpm

3.配置环境变量，并验证是否安装成功

vi /etc/profile

JAVA_HOME=/usr/java/jdk1.7.0_75

CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar

PATH=$JAVA_HOME/bin:$PATH

export JAVA_HOME CLASSPATH PATH

java -version

javac -version
