root用户进入linux系统：
查看jdk安装路径：#echo $JAVA_HOME [root@sj ~]# echo $JAVA_HOME/usr/java/jdk1.6.0_45 .修改脚本文件rc.local，添加启动路径和jdk路径：# vim /etc/rc.d/rc.local
这个脚本是使用者自定的开机启动程序，可以土豪的月光添加想在系统启动之后执行的脚本或者脚本执行命令
touch /var/lock/subsys/localexport JAVA_HOME=/usr/java/jdk1.6.0_45/woyi/tomcat/apache-tomcat-7.0.93/axdxtz/startup.sh start 将rc.local修改为可执行，执行命令 # chmod 777 /etc/rc.d/rc.local 注意：echo $JAVA_HOME能定位JDK的安装路径的前提是配置了环境变量$JAVA_HOME，否则如下所示，根本定位不到JDK的安装路径 [root@localhost /]# echo $JAVA_HOME[root@localhost /]#

还可以通过tomcat启动日志可以看到`
