是否可以在没有Gnome和X11一半的情况下安装JDK？和声音主题？这是一个无头(无扬声器)服务器.

解决方法:

更新

我个人试图避免使用Java,因为在我看来它非常笨拙.
这些说明是从各种来源拼凑而成的,
我最近必须安装Java,这应该适合你.

如果您的许可要求允许,请安装Oracle Java.
从here下载java,你需要根据你安装的内容选择你需要的那个.

JDK x64

wget --no-check-certificate --no-cookies - --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/7u51-b13/jdk-7u51-linux-x64.tar.gz

JDK x32

wget --no-check-certificate --no-cookies - --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/7u51-b13/jdk-7u51-linux-i586.tar.gz

JRE x64

wget --no-check-certificate --no-cookies - --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/7u51-b13/jre-7u51-linux-x64.tar.gz

JRE x32

wget --no-check-certificate --no-cookies - --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/7u51-b13/jre-7u51-linux-i586.tar.gz

请注意,您需要一个wget和oracle一起使用的解决方法.

创建Java所在的目录：

sudo mkdir -p /usr/lib/jvm

移动下载的Java：

sudo mv jdk-7u51-linux-x64.tar.gz /usr/lib/jvm

提取Java：

sudo tar zxvf jdk-7u51-linux-x64.tar.gz

告诉Ubuntu Java存在：

sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.7.0_51/bin/javac 1
sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.7.0_51/bin/java 1
sudo update-alternatives --set javac /usr/lib/jvm/jdk1.7.0_51/bin/javac
sudo update-alternatives --set java /usr/lib/jvm/jdk1.7.0_51/bin/java

将java路径添加到系统配置文件中,以便机器知道Java二进制文件的位置：

sudo nano /etc/profile

在文件的末尾添加：

JAVA_HOME=/usr/lib/jvm/jdk1.7.0_51
PATH=$PATH:$JAVA_HOME/bin
export JAVA_HOME
export PATH

保存并重启.

测试您的Java安装：

java -version
