Ubuntu 安装常用工具

1.   Installjdk1.7/1.8

Firstly, you need to add PPA:

sudoadd-apt-repository ppa:webupd8team/java

sudo apt-getupdate

 

Secondly, installoracle-jave-installer

Jdk7

sudo apt-get install oracle-java7-installer

jdk8

sudo apt-get install oracle-java8-installer

 

Installer willnotice you to agree some terms of services, SELECT ok, and the SELECT yes.

(Chooseable)

/**

But if you aretoo lazy to lift you fingers, you can add some cmds like this:

Jdk7

echo oracle-java7-installer shared/accepted-oracle-license-v1-1select true | sudo /usr/bin/debconf-set-selections

Jdk8

echo oracle-java8-installer shared/accepted-oracle-license-v1-1select true | sudo /usr/bin/debconf-set-selections

**/

Now ,you just need to wait it download from the internet.If your net’s speed is very slow, you can download the compressed file, such asxxxx.tar.gz, and copy the xxx.tar.gz to:

       /var/cache/oracle-jdk7-installer                (jdk7) 

       /var/cache/oracle-jdk8-installer                 (jdk8) 

Then, reinstall the installer.

Thirdly, set jdk environment

JDk7

sudo update-java-alternatives -s java-7-oracle

JDK8

If you have installed both jdk7 and jdk8, and you need to switchform 1.7 to 1.8 or 1.8 to 1.7, you can do like this:

Download eclipse-java-neon-2-linux-gtk-x86_64.tar.gzfrom eclipse’s official website

Then uncompress it toyour workhome

Secondly, Create fast launch menu:

Note：we can move eclipse.desktopto /home/dezhou/SoftWares/eclipse (Your eclipseroot path)，and create a soft linkto/usr/share/applications，in thiscase we don’t need to recreate eclipse.desktop file when we reinstall oursystem。

cd /usr/share/applications
