如何在今天的Linux上自动下载和安装Java JDK？
作者：互联网
关于如何在Linux上自动下载Java JDK,有一个很好的答案：
Downloading Java JDK on Linux via wget is shown license page instead
所描述的方法不再有效.看来Oracle再次更改了对其下载服务器的限制以阻止此方法.我想他们不希望Java在自动缩放服务器系统(例如AWS)中使用.他们在想什么？
我正在尝试的特定命令是将最新的7u51版本下载到AWS服务器,以便我可以安装Web应用程序：
wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2%2Fwww.oracle.com%2F" "http://download.oracle.com/otn-pub/java/jdk/7u51-b13/jdk-7u51-linux-i586.rpm"
如封闭答案中所述,这不再绕过OTN许可协议：
https://stackoverflow.com/a/21431491/2144836
从浏览器尝试此操作,我发现下载链接正在查询参数中添加其他身份验证：
http://download.oracle.com/otn-pub/java/jdk/7u51-b13/jdk-7u51-linux-i586.rpm?AuthParam=1392853518_cb83fe47e04500eecccdb66722756fb3
将带有AuthParam的链接复制并粘贴到wget调用中也不起作用.我最初的猜测是它与会话或IP地址相关.
尝试将其手动下载到服务器(或一天一百次到一百台服务器)是不合理的,因此我希望找到一种可以解决当前限制的解决方法.
因此,今天,有没有一种解决方法可以自动下载最新的JDK？还是我应该完全放弃Oracle？
解决方法:
您的命令对我来说很好.检查以下内容：
$ls jdk*
ls: cannot access jdk*: No such file or directory
$wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2%2Fwww.oracle.com%2F" "http://download.oracle.com/otn-pub/java/jdk/7u51-b13/jdk-7u51-linux-i586.rpm"

运行此命令时会出现什么错误？我在3个不同的地方尝试了您的命令,并且每次都有效.
