Installation of IntelliJ idea 14 under Linux

First, install the configuration JDK

While many Linux distributions now come with OPENJDK, they are slightly different from ORACLE-JDK (SUN-JDK) during development. Typically, Java developers are developing with ORACLE-JDK as a standard. Here's a look at the JDK installation and configuration under Linux, and the Linux distribution used here is Ubuntu 12.04.

1. Download the JDK

The latest version is: Jdk8u25 (as of November 12, 2014), where we use version jdk7u71/72

: http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

Check Latest: http://www.oracle.com/technetwork/java/javase/downloads/index.html

2. Unzip the installation

We install the JDK to this path:/USR/LIB/JVM. If you do not have this directory, create a new directory

cd/usr/libsudomkdir JVM

After the establishment, enter the directory of the compressed package that you just downloaded, unzip to the newly created folder, and modify the name to facilitate management

sudo tar zxvf./jdk-7-linux-i586. tar. GZ  -c/usr/lib//usr/lib/jvmsudomv jdk1.  7. 0_71/jdk7

3. Configure Environment Variables

VI  /etc/profile

Add at the end of the open file

Export java_home=/usr/lib/jvm/jdk7export jre_home=${java_home}/jreexport CLASSPATH=.:${java _home}/lib/tools.jar:${jre_home}/lib/dt.jarexport PATH

Save the exit and enter the following command to make it effective

Source/etc/profile

4. Configure the default JDK

Some Linux distributions already have default JDK, such as OPENJDK. So in order to make the JDK version we just installed can be the default JDK version, we will also make the following configuration.
Execute the following command:

sudo update-alternatives--installsudo update-alternatives--Install   -

Note: If the above two commands do not find a path problem, just restart the computer and repeat the above two lines of code is OK.

Execute the following code to see the current various JDK versions and configurations:

sudo update-alternatives--config javasudo update-alternatives--config javac

5. Testing

Open a terminal and enter the following command:

Java-version

Show Results:

" 1.7.0_71 "  1.7. 0_71-23.1-b03, Mixed mode)

Second, installation configuration IntelliJ idea 14

1. Download IntelliJ IDEA14

: http://www.jetbrains.com/idea/download/

2. Unzip the downloaded ideaiu-14.tar.gz to/usr/intellijidea

tar -zxvf ideaiu-14. tar. Gz-c/usr/intellijidea

3, it seems to configure the environment variables

Export IDEA_JDK=/USR/LIB/JVMJ/JDK1. 7. 0_71

4. Enter the bin directory under the installation directory to perform

./idea. SH

5 , enter the registration code after running.

Key:idea

Value:61156-yrn2m-5mncn-nz8d2-7b4ew-u12l4
