Linux实战4——安装IntelliJ IDEA
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
