如何安装JAVA 8 Debian 8

Question

我一直在debian中安装java 8，如下所示：

echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main" > /etc/apt/sources.list.d/webupd8team-java.list

echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main" >> /etc/apt/sources.list.d/webupd8team-java.list

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EEA14886
apt-get update && apt-get install oracle-java8-installer -y

但别忘了，这已经行不通了。

E: Unable to find the oracle8-java-installer package

我尝试了下面的另一步，但是我得到了同样的错误：

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

Answer 1

下载(所需甲骨文帐户)

https://www.oracle.com/technetwork/java/javaee/downloads/jdk8-downloads-2133151.html

jdk-8u211-linux-x64.tar.gz

作为根

cp jdk-8u211-linux-x64.tar.gz /usr/lib/jvm/

cd /usr/lib/jvm/

tar zxvf jdk-8u211-linux-x64.tar.gz

要设置为默认运行，请执行以下操作：

update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.8.0_211/bin/java 4

update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.8.0_211/bin/javac 4

update-alternatives --config java

​

​

然后选择选项4 (因为以前运行了update--install /usr/bin/java /usr/lib/jvm 1.8.0_211/bin/ java 4)
