增加:
JAVA_HOME=/usr/local/jdk1.6
JRE_HOME=/usr/local/jdk1.6/jre
PATH=$PATH:/usr/local/jdk1.6/bin:/usr/local/jdk1.6/jre/bin
CLASSPATH=.:/usr/local/jdk1.6/lib/dt.jar:/usr/local/jdk1.6/lib/tools.jar:/usr/local/jdk1.6/jre/lib:
export JAVA_HOME JRE_HOME PATH CLASSPATH
保存后退出

使环境变量生效
source /home/$USER/.bashrc

启动eclipse

如果有以下提示，则说明环境变量配置有问题

A Java Runtime Environment(JRE)OR Java Development Kit(JDK) must be available in order to run eclipse.No java virtual machine was found after searching the following locations: d:\eclipse\eclipse\jre\bin\javaw.exe javaw.exe in your current PATH
