Linux实战4——安装IntelliJ IDEA

阅读更多

1. 下载IDEA
   官网地中：http://www.jetbrains.com/idea/download/index.html
   选择对应操作系统的版本。下载后，我的文件名称为： ideaIU-11.1.1.tar.gz

2. 安装
   2.0 拷贝到安装位置（安装其实就是解压过程）
   2.1 解压
       /opt/idea-IU-117.117/bin $ sudo tar -xvf ideaIU-11.1.1.tar.gz
   2.2 运行，提示错误
       /opt/idea-IU-117.117/bin $ sh idea.sh
错误日志：

OpenJDK Runtime Environment (IcedTea6 1.11.3) (6b24-1.11.3-1ubuntu0.12.04.1)
OpenJDK Client VM (build 20.0-b12, mixed mode, sharing)
WARNING: You are launching the IDE using OpenJDK Java runtime.

         THIS IS STRICTLY UNSUPPORTED DUE TO KNOWN PERFORMANCE AND GRAPHICS PROBLEMS!

NOTE:    If you have both Oracle (Sun) JDK and OpenJDK installed
         please validate either IDEA_JDK, JDK_HOME, or JAVA_HOME environment variable points to valid Oracle (Sun) JDK installation.
         See http://ow.ly/6TuKQ for more info on switching default JDK.

Press Enter to continue.

貌似用默认的Open jdk不行，切换回Sun的jdk，就重新配置一下。

3. 安装Sun jdk
