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: http://www.webupd8.org/2012/01/install-oracle-java-jdk-7-in-ubuntu-via.html
|
||
Debian installation instructions: http://www.webupd8.org/2012/06/how-to-install-oracle-java-7-in-debian.html
|
||
More info: https://launchpad.net/~webupd8team/+archive/java
|
||
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 keyserver.ubuntu.com
|
||
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)
|
||
OK
|
||
|
||
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:
