Linux:使用PPA在Elementary OS 'Luna'上安装Oracle Java 7

问题: 我该如何在 Elemetary OS Luna 上安装Oracle Java 7?

回答: 在 Elementary OS Luna 安装 Java 7 的步骤如下: 由于Elementary OS是基于Ubuntu,所以我们允许使用具有多种Java包的WEPUD8 PPA

  1. 打开终端。

  2. 运行以下指令添加Java的PPA到你的软件仓:

    $ sudo add-apt-repository ppa:webupd8team/java
    You are about to add the following PPA to your system:
    Oracle Java (JDK) Installer (automatically downloads and installs Oracle JDK6 / JDK7 / JDK8). There are no actual Java files in this PPA. More info:
    Debian installation instructions:
    More info:
    Press [ENTER] to continue or ctrl-c to cancel adding it
  3. 按回车继续

    gpg: keyring `/tmp/tmpB5WwDG/secring.gpg' created
    gpg: keyring `/tmp/tmpB5WwDG/pubring.gpg' created
    gpg: requesting key EEA14886 from hkp server
    gpg: /tmp/tmpB5WwDG/trustdb.gpg: trustdb created
    gpg: key EEA14886: public key "Launchpad VLC" imported
    gpg: Total number processed: 1
    gpg: imported: 1 (RSA: 1)
  4. 现在更新你的系统

    $ sudo apt-get update
  5. 运行以下命令安装Java 7:

    $ sudo apt-get install oracle-java7-installer
    [sudo] password for enock:
    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    The following packages were automatically installed and are no longer required:

    libmagickcore4-extra liblqr-1-0 imagemagick-common libpathplan4 libopenexr6
    rsync netpbm libgvc5 libnetpbm10 libgraph4
    Use 'apt-get autoremove' to remove them.
    The following extra packages will be installed:
    gsfonts-x11 java-common
    Suggested packages:

    Need to get 88.5 kB of archives.
    After this operation, 473 kB of additional disk space will be used.
    Do you want to continue [Y/n]?
  6. 输入代表Yes的Y以及回车键继续安装。

  7. 在安装过程中,你需要同意条款才能继续。选择OK

  8. 然后选择Yes继续。

  9. 现在请等待安装包的下载与自动安装:

  10. 安装完成。你可以在终端上查看Java版本:

    $ java -version
    java version "1.7.0_45"
    Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
    Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)
