在适用于Linux的Windows子系统上安装Oracle JDK [英] Installing Oracle JDK on Windows subsystem for Linux

问题描述

当尝试在支持bash的最新Windows 10版本上使用Linux版本的Oracle JDK时，每当尝试调用 java 二元。

When trying to use the Linux version of Oracle's JDK on the latest Windows 10 build having support for bash, I am running into a problem with the prompt hanging whenever attempting to invoke the java binary.

键入甚至像 java -version 这样简单的东西挂起，我必须终止进程恢复控制。

Typing even something as simple as java -version hangs and I have to terminate the process to resume control.

任何人都可以使用它吗？

Anyone got this working yet?

推荐答案

我想澄清一下，截至2016年12月9日，您肯定可以在Ubuntu Bash for Windows 10上安装Java 8，并且@Karl Horton是正确的。

I wanted to clarify that as of 9 December 2016, you most certainly can install Java 8 on Ubuntu Bash for Windows 10 and that @Karl Horton is correct.

您需要安装解压缩 sudo apt-get install unzip

将此脚本复制到您的某个位置bash for windows session并使其可执行（chmod + x filename）。如果你不使用基于命令行的编辑器（如vim），那么你将有windows行结尾来处理。您可以使用dos2unix或您首选的处理方式。我只是使用vim将其粘贴到一个文件中。

Copy this script somewhere in your bash for windows session and make it executable (chmod +x filename). If you do not use a command line based editor such as vim then you will have windows line endings to deal with. you can use dos2unix or your preferred way of dealing with that. I just paste it into a file using vim.

 #!/bin/bash

set -ex

# UPDATE THESE URLs
export JDK_URL=http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz
export UNLIMITED_STRENGTH_URL=http://download.oracle.com/otn-pub/java/jce/8/jce_policy-8.zip

# Download Oracle Java 8 accepting the license
wget --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" \
${JDK_URL}
# Extract the archive
tar -xzvf jdk-*.tar.gz
# clean up the tar
rm -fr jdk-*.tar.gz
# mk the jvm dir
sudo mkdir -p /usr/lib/jvm
# move the server jre
sudo mv jdk1.8* /usr/lib/jvm/oracle_jdk8

# install unlimited strength policy
wget --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" \
${UNLIMITED_STRENGTH_URL}
unzip jce_policy-8.zip
mv UnlimitedJCEPolicyJDK8/local_policy.jar /usr/lib/jvm/oracle_jdk8/jre/lib/security/
mv UnlimitedJCEPolicyJDK8/US_export_policy.jar /usr/lib/jvm/oracle_jdk8/jre/lib/security/

sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/oracle_jdk8/jre/bin/java 2000
sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/oracle_jdk8/bin/javac 2000

sudo echo "export J2SDKDIR=/usr/lib/jvm/oracle_jdk8
export J2REDIR=/usr/lib/jvm/oracle_jdk8/jre
export PATH=$PATH:/usr/lib/jvm/oracle_jdk8/bin:/usr/lib/jvm/oracle_jdk8/db/bin:/usr/lib/jvm/oracle_jdk8/jre/bin
export JAVA_HOME=/usr/lib/jvm/oracle_jdk8
export DERBY_HOME=/usr/lib/jvm/oracle_jdk8/db" | sudo tee -a /etc/profile.d/oraclejdk.sh

现在我可以做以下事情

fieldju@DESKTOP-LTL6MIC:~$ java -version
java version "1.8.0_112"
Java(TM) SE Runtime Environment (build 1.8.0_112-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.112-b15, mixed mode)                                                

上述脚本中的链接和版本可能在您阅读本文时已过期，因此请转到 http://www.oracle.com/technetwork/java/javase/downloads/index.html 接受许可证，以便他们的js允许您复制新的URL，你应该很高兴。

The links and versions in the above script are likely to be out of date by the time you read this, so just head over to http://www.oracle.com/technetwork/java/javase/downloads/index.html accept the license so that their js lets you copy the new URLs and you should be good to go.
