ubuntu安装IDEA2016

首先安装jdk8

其次下载IDEA2016的linux版本，是个tar.gz包

创建目录

sudo mkdir /usr/local/jetbrains

复制下载好的tar.gz包到这个目录

sudo cp ideaIU-2016.2.5.tar.gz /usr/local/jetbrains/

切换目录并解压

cd /usr/local/jetbrains/sudo tar -zxvf ideaIU-2016.2.5.tar.gz

创建软链接

sudo ln -s /usr/local/jetbrains/idea-IU-162.2228.15 idea2016

查看安装指导文件

cd idea2016cat Install-Linux-tar.txt

如果安装指导比较长可以加more或者less命令查看

cat Install-Linux-tar.txt |morecat Install-Linux-tar.txt |less

这里直接把文件内容贴过来

IntelliJ IDEAINSTALLATION INSTRUCTIONS===============================================================================  Linux Installation Instructions  ------------------------------------------------------------------------------  1. Unpack the IntelliJ IDEA distribution archive that you downloaded to     where you wish to install the program. We will refer to this destination     location as your {installation home} below.  2. Open a console and cd into "{installation home}/bin" and type:       ./idea.sh     to start the application. As a side effect, this will initialize various     configuration files in the ~/.IntelliJIdea2016.2 directory.  3. [OPTIONAL] Add "{installation home}/bin" to your PATH environment     variable so that you may start IntelliJ IDEA from any directory.  4. [OPTIONAL] To adjust the value of the JVM heap size, create      ~/.IntelliJIdea2016.2/idea.vmoptions (or idea64.vmoptions      if using a 64-bit JDK), and set the -Xms and -Xmx parameters. To see how      to do this, you can reference the vmoptions file under      "{installation home}/bin" as a model.  [OPTIONAL] Changing the location of "config" and "system" directories  ------------------------------------------------------------------------------  By default, IntelliJ IDEA stores all your settings under the ~/.IntelliJIdea2016.2/config  directory and uses ~/.IntelliJIdea2016.2/system as a data cache.  If you want to change these settings,  1. Open a console and cd into ~/.IntelliJIdea2016.2/  2. Create the file "idea.properties" and open it in an editor. Set the     idea.system.path and/or idea.config.path variables as desired, for     example:     idea.system.path=~/custom/system     idea.config.path=~/custom/config  3. Note that we recommend to store data cache ("system" directory) on a disk     with at least 1GB of free space.Enjoy!-IntelliJ IDEA Development Team

大致内容是说切换到bin目录，然后执行./idea.sh就可以用了，配置文件默认放到了~/.IntelliJIdea2016.2/目录，升级版本到时候要注意这个文件夹，反正我是没正常升级过，这个等出来2016.3的正式版再研究

下面执行

cd bin/./idea.sh

到这里就算安装完成了

后记:

2016.3出正式版了,在ubuntu下解压，执行./idea.sh文件，选择不导入之前的配置，是一次干净的升级。ubuntu上没有卸载之前的安装这个过程，导入之前的配置可能会出各种问题。
