             （又转载了一位外国GG）
             
             
I’ve been a user of the excellent 
             
             IntelliJ Java IDE for 4 years on Windows. Even though the official Linux support by JetBrains is only for RedHat, you can also install IntelliJ fairly easily on 
             
             Ubuntu. I’ve tested this with 
             
             Xubunto 7.10 (Gutsy), 
             
             Java 6, and IntelliJ 7. Here’s how to do it in four basic steps:
             
             
1) Get Java
             
             
Install the Java 6 JDK, which IDEA itself needs to run. (You can have other JDKs for your projects, but you’ll need this one to run IntelliJ itself.) For example, type this in a terminal:
             
             
sudo apt-get install sun-java6-jdk

             
             
Follow the prompts for root password, download confirmation, and eventually the Sun EULA to install Java itself. If it installed successfully, you should be able to type this at a prompt:

             
             
java -version

             
             
… to get several lines telling you the version of Java you have installed. If this doesn’t work, refer to Sun’s documentation on troubleshooting installations.

             
             
2) Get IntelliJ IDEA

             
             
Download the latest version of IntelliJ IDEA for Linux:

             
             
http://www.jetbrains.com/idea/download/index.html#linux

             
             
Once the download is finished, extract the archive using the correct filename according to your download. For example, to install IntelliJ in /usr/lib, do the following:

             
             
tar xfz idea-7.0.1.tar.gz ./usr/lib/

             
             
The IntelliJ installation will now be in a subdirectory indicating the build number, in the format “idea-xxxx”. In the case of IDEA 7.0.1, the app directory is “idea-7364“. (Once the extraction is done, you can delete the downloaded archive to conserve disk space if needed.)

             
             
3) Get Environmental

             
             
There are a couple of environment variables to be taken care of. First, you need to set a new environment variable that tells IntelliJ where your install of Java is. For example:

             
             
export JDK_HOME="/usr/lib/jvm/java-6-sun/"

             
             
Use the “env” command, or just “echo $JDK_HOME“, to verify the variable is set.

             
             
Next, you’ll need to edit /etc/environment with superuser rights in the editor of your choice, adding the idea-xxxx/bindirectory to your PATH variable. For example, you can edit the environment with the GUI mousepad editor like so:

             
             
sudo mousepad /etc/environment

             
             
The various directories in the environment PATH variable are delineated by colons (:). Append the current value (inside the quotes) with a new colon and then add the idea-xxxx/bin location. It should look something like this:

             
             
PATH="/usr/local/sbin:/usr/local/bin:/usr/lib/idea-7364/bin"

             
             
Save and close the environment file. You’ll need to “source” it for your system to pick up the new directory in the PATH. You can verify your changes by echoing the variable as well:

             
             
source /etc/environment

             
             
echo $PATH

             
             
If you see the path to IntelliJ returned in the output, you’re all set.

             
             
Lastly, you may want to change the VM settings of IntelliJ. This depends entirely on your project size and other factors, so you’ll need to base these settings on your own need. The settings are in idea-xxx/bin/idea.vmoptions.

             
             
4) Get Started!

             
             
That’s it. Now you can run “idea.sh” from a terminal in any directory, and IntelliJ should launch…

             
             
sh idea.sh

             
             
If you run into problems, be sure to double-check the readme files in the installation directory.
