在linux mint 上安装 Oracle JDK 的方法

Dec 28, 2015 · 1 min read · jdk

  1. Open up the Terminal (Alt + F2 > Terminal).

  2. Remove OpenJDK installation.

    sudo apt-get update && apt-get remove openjdk*

  3. Download Oracle JDK from here. You are looking for a linux version with tar.gz extension. Also choose the right version from 32-bit (x86)  and 64bit (x64) one.

  4. Change directory into one with downloaded tarball. In my case $HOME/Downloads.

    cd ~/Downloads

  5. Extract tarball. Replace with a name of dowloaded file. (just press Tab and it will be autocompleted.)

    tar -zxvf jdk-

  6. As a root create a folder in /opt where jdk will be stored.

    sudo mkdir -p /opt/java

  7. Move extracted folder to /opt/java. In my case, version number was 1.7.0_25.

    sudo mv jdk1.7.0_25 /opt/java

  8. Make JDK system default.

    sudo update-alternatives --install "/usr/bin/java" "java" "/opt/java/jdk1.7.0_25/bin/java" 1

    sudo update-alternatives --set java /opt/java/jdk1.7.0_25/bin/java

  9. Test installed java version.

java version "1.7.0_25" Java(TM) SE Runtime Environment (build 1.7.0_25-b15) Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)

$ java -version
