从Oracle下载sun jdk提示：In order to download products from Oracle Technology Network you must agree to the OTN license terms.
这是可通过如下命令解决：
wget --no-cookies --no-check-certificate --header "Cookie: oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/7u15-b03/jdk-7u15-linux-x64.tar.gz" -O ~/Linux-sunjdk-7u15.tar.gz
其中可将url换成其他想要下载的链接。（右键复制想要下载却下载不了的链接）
