In the case of Ubuntu, there is a useful utility called `update-java-alternatives` that [displays and configures which java environment][3] to use at any point in time. - -Those of you using a different Linux distro can, in general, take a similar approach. Several other distros (such as Debian and Mint) also use `apt`, though the available packages may differ. Other distros use different package managers. For example, [the Fedora documentation page for Installing Java][4] shows how to use the Fedora `dnf` package manager to handle the installation. First, to show the available version, type: - - -``` -`dnf search openjdk` -``` - -Next, to install the full development x86_64 architecture version, type: - - -``` -`sudo dnf install java-11-openjdk-devel.x86_64` -``` - -Similarly, Fedora provides the `alternatives` utility to [display and configure the Java environment][5]. - -For another example, the [wonderful Arch Linux wiki][6] shows the corresponding package is `jdk11-openjdk`**.** The wiki also explains many other important details related to using Java in Arch, such as using the `archlinux-java` utility to show what Java environments are installed or select a different default environment. Arch uses a package manager called `pacman`, which is also documented [here on the Arch Linux wiki][7]. - -Regardless of which distribution and package manager you prefer, it is easy to get Java on your Linux system. Consider version and function, of course, before installing. Also keep in mind that there are options for managing two or more Java versions on the same computer. Most of my examples used `apt`, but keep in mind the `dnf` options, too. - --------------------------------------------------------------------------------- - -via: https://opensource.com/article/21/9/install-java-linux-repositories - -作者：[Chris Hermansen][a] -选题：[lujun9972][b] -译者：[译者ID](https://github.com/译者ID) -校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 - -[a]: https://opensource.com/users/clhermansen -[b]: https://github.com/lujun9972 -[1]: https://opensource.com/sites/default/files/styles/image-full-size/public/lead-images/java-coffee-mug.jpg?itok=Bj6rQo8r (Coffee beans and a cup of coffee) -[2]: https://openjdk.java.net/ -[3]: http://manpages.ubuntu.com/manpages/hirsute/man8/update-java-alternatives.8.html -[4]: https://docs.fedoraproject.org/en-US/quick-docs/installing-java/ -[5]: https://tecadmin.net/install-java-on-fedora/ -[6]: https://wiki.archlinux.org/title/java#OpenJDK -[7]: https://wiki.archlinux.org/title/pacman#Querying_package_databases diff --git a/translated/tech/20210927 Install Java from your Linux distribution-s repositories.md b/translated/tech/20210927 Install Java from your Linux distribution-s repositories.md new file mode 100644 index 0000000000..c04dd813fd --- /dev/null +++ b/translated/tech/20210927 Install Java from your Linux distribution-s repositories.md @@ -0,0 +1,122 @@ +[#]: subject: "Install Java from your Linux distribution's repositories" +[#]: via: "https://opensource.com/article/21/9/install-java-linux-repositories" +[#]: author: "Chris Hermansen https://opensource.com/users/clhermansen" +[#]: collector: "lujun9972" +[#]: translator: "geekpi" +[#]: reviewer: " " +[#]: publisher: " " +[#]: url: " " + +从你的 Linux 发行版的仓库中安装 Java +====== +无论你喜欢哪个发行版和包管理器，都可以都很容易在您的 Linux 系统上安装 Java。 +![Coffee beans and a cup of coffee][1] + +有许多不同的方法可以把 Java 安装到你的 Linux 桌面上。一个明显的途径是使用你的 Linux 发行版中提供的软件包。请注意，这并不适合所有人。例如，有些用户可能需要一个非常具体的 Java 版本。 + +在你开始之前，你必须确定你需要“哪种 Java”。你是否只需要运行一些 `.class` 文件或 `.jar` 文件？还是你正在编写一些需要编译的代码？ + +就我而言，我运行的大部分 Java 都是我自己（至少部分）编写的 Java，所以安装完整的 Java 开发工具包（或称 JDK）总是有意义的，它包含了 Java 编译器、库和一些非常有用的工具。当然，在这里，我们更倾向于使用开源的 JDK，称为 [OpenJDK][2]。 + +由于我主要在 Ubuntu Linux 发行版上工作，我的软件包管理器是 `apt`。我可以用 `apt` 来查找哪些 OpenJDK 包是可用的： + + +``` +`apt list OpenJDK\*` +``` + +这个命令的输出看起来像这样： + + +``` +Listing...
