解决Linux下启动Tomcat遇到Neither the JAVA_HOME ...报错

Neither the JAVA_HOME nor the JRE_HOME environment variable is defined

At least one of these environment variable is needed to run this program

找不到JAVA_HOME路径，需要做以下变更：

找到启动路径所在的目录：

cd bin/

vi catalina.sh

加入以下信息：

export  JAVA_HOME=/home/gongzi/http/jdk1.6.0_26

export  JRE_HOME=/home/gongzi/http/jdk1.6.0_26/jre
