Oracle不允许直接从他们的服务器下载jdk，看这里[http://www.oracle.com/technetwork/java/javase/terms/license/index.html]
所以如果你尝试这样：
wget "http://download.oracle.com/otn-pub/java/jdk/7u4-b20/jdk-7u4-linux-x64.tar.gz"
你将得到一个许可条款的页面，幸运的是,你需要一个cookie可以绕过这个：
Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie
所以,如果你想下载64位的Linux(例如jdk7u4使用wget,Ubuntu),您可以使用:
wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u60-b27/jdk-8u60-linux-x64.tar.gz"
仅供参考,以下是JDK8的下载项目，其他的可以在oracle官网找到

以上脚本中下载JDK的方式根据自己需求修改即可。
