Build a Python development environment in Ubuntu 13.10

Build a Python development environment in Ubuntu 13.10:

Step 1 install JDK (to install eclipse ide)

Decompress the installation package and set JDK.

The update-alternatives -- install option feature adds a new set of system command links.

Tar-zxvf jdk-7u45-linux-x64.tar.gz
Sudo mkdir-p/usr/lib/jvm
Sudo mv./jdk1.7.0 _ 45/usr/lib/jvm/jdk1.7.0
Sudo update-alternatives -- install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.7.0/bin/java" 1
Sudo update-alternatives -- install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.7.0/bin/javac" 1
Sudo update-alternatives -- install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk1.7.0/bin/javaws" 1

Use the update-alternatives-config command to select one of the existing command links as the system default.

Sudo update-alternatives -- config java
Sudo update-alternatives -- config javac

For example, if multiple JDK is installed, you can select one as the default one:

$ Sudo update-alternatives -- config java
There are 3 choices for the alternative java (providing/usr/bin/java ).

Selection Path Priority Status

* 0/usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 auto mode
1/usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 manual mode
2/usr/lib/jvm/java-6-sun/jre/bin/java 63 manual mode
3/usr/lib/jvm/jdk1.7.0/jre/bin/java 3 manual mode

Press enter to keep the current choice [*], or type selection number: <SPAN style = "COLOR: # ff0000"> 3 </SPAN>
Update-alternatives: using/usr/lib/jvm/jdk1.7.0/jre/bin/java to provide/usr/bin/java (java) in manual mode.

Set the execution permission:

Sudo chmod a + x/usr/bin/java
Sudo chmod a + x/usr/bin/javac
Sudo chmod a + x/usr/bin/javaws
Sudo chown-R root: root/usr/lib/jvm/jdk1.7.0

If you want to install Firefox plugin

Mkdir ~ /. Mozilla/plugins
Ln-s/usr/lib/jvm/jdk1.7.0/jre/lib/amd64/libnpjp2.so ~ /. Mozilla/plugins/
Sudo/etc/init. d/apparmor restart

Check whether java installation is successful

Java-version
