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
