如何给Alpine Linux安装Oracle JDK

Docker cp jdk1.8.0_231.tar.gz alpine:/usr/local/share/javaAlpine容器里解压查看jdk版本/usr/local/share/java # lsjdk1.8.0_231.tar.gz## 解压tar -zxvf jdk1.8.0_231.tar.gz## 重新命个名mv jdk1.8.0_231 jdk## 查看版本  not found问题/usr/local/share/java # /usr/local/share/java/jdk/bin/java -version/bin/sh: /usr/local/share/java/jdk/bin/java: not found

This is more of a musl libc issue. The Oracle Java binaries only run on glibc at the moment. We are looking at possibly rebuilding https://aur.archlinux.org/packages/jd/jdk/PKGBUILD and making it avAIlable as a standalone package. I'll keep this issue open for now as we have had requests for Java 8 multiple times already.

Then why are you trying to use that glibc package on Alpine? This is unofficial hack that is not supported by Alpine community. The only officially supported JRE/JDK are the mentioned openjdk packages built against musl libc.## 你为啥要在alpine使用glibc库呢，这是不受Alpine社区支持的非官方的库，官方唯一支持的就只有针对musl libc构建的openjdk包。## 有人提问Our project is very complex and getting it running on OpenJDK would likely be very costly...## 我们的项目非常复杂，如果改成运行在OpenJDK可能代价非常大。## 回答Then you’re probably doing it wrong… Oracle JDK is just branded distribution of OpenJDK, the code base is nearly identical. That said, exceptions may exist, mainly in case of graphic Applications.## 那你可能错了，Oracle JDK只是OpenJDK的一个发行版，代码库基本是一样的，例外可能存在，主要是在图形应用程序的情况下（意思是应该可以无缝迁移）If you really need OracleJDK, then use some glibc-based distribution, not Alpine. Adding glibc to Alpine is not a stable production-quality solution.## 如果你真的选择OracleJDK，那使用一些基于glibc的发行版而不是使用Alpine，在Alpine中添加glibc库并不是生产上完美的解决方案# 继续看别人提问I hope alpine considers officially supporting oracle java in the future.## 我希望alpine考虑在未来正式支持oracle java。Once again. Oracle JDK is a proprietary product, they don’t provide source-code of all their modifications to OpenJDK and build system, just binaries. These binaries are build against glibc (GNU C Library). Alpine Linux doesn’t use glibc, it’s based on (much better) musl libc.## 再解释一遍，oracle jdk它是一个专属产品，它在OpenJDK之上写的源代码不提供啊，就仅仅提供了一个二进制文件还是基于glibc编译的，Alpine不使用glibc，它是基于更小的musl libcGlibc and musl libc are (partially) incompatible (mainly because glibc doesn’t comply with POSIX standards). Therefore software built against glibc may not work on musl libc without recompiling. This is the case of Oracle JDK. Because it’s a proprietary product, we can’t recompile it and there’s nothing we can do about it!## Glibc和musl libc(部分)不兼容，主要是因为Glibc不符合POSIX标准，所以基于glibc构建的软件如果不重新编译就可能无法在musl libc上运行（因为那部分的不兼容），这就是目前不支持OracleJDk的情况，OracleJDk它又是一个私有产品，我们拿不到源码不能重新编译，我们也无能为力呀。libc is a very base system library, it’s not yet another library you can simply install along with others. Adding support for glibc would basically mean supporting another platform. The cost of this is too high. Also it doesn’t make much sense; Alpine with glibc would not be Alpine anymore! Alpine’s “motto” is: small, simply and secure. You can’t get this with glibc.
