linux 下tomcat开机自启动
1、把下面的代码保存为tomcat文件，并让它成为可执行文件 chmod 755 tomcat.
#!/bin/bash
#
# kenny kenny.zhou@tom.com
# /etc/rc.d/init.d/tomcat
# init script for tomcat precesses
#
# processname: tomcat
# description: tomcat is a j2se server
# chkconfig: 2345 86 16
# description:  Start up the Tomcat servlet engine.

if [ -f /etc/init.d/functions ]; then
        . /etc/init.d/functions
elif [ -f /etc/rc.d/init.d/functions ]; then
        . /etc/rc.d/init.d/functions
else
        echo -e "\atomcat: unable to locate functions lib. Cannot continue."
        exit -1
fi

RETVAL=$?
CATALINA_HOME="/usr/local/tomcat"

case "$1" in
start)
        if [ -f $CATALINA_HOME/bin/startup.sh ];
          then
            echo $"Starting Tomcat"
            $CATALINA_HOME/bin/startup.sh
        fi
        ;;
stop)
        if [ -f $CATALINA_HOME/bin/shutdown.sh ];
          then
            echo $"Stopping Tomcat"
            $CATALINA_HOME/bin/shutdown.sh
        fi
        ;;
*)
        echo $"Usage: $0 {start|stop}"
        exit 1
        ;;
esac

exit $RETVAL

2、将tomcat文件拷贝到/etc/init.d/下，并运行：chkconfig --add tomcat

3、在tomcat/bin/catalina.sh文件中加入以下语句：
export JAVA_HOME=/YOURPATH/tomcat/jdk
export CATALINA_HOME=/YOURPATH/tomcat
export CATALINA_BASE=/YOURPATH/tomcat
export CATALINA_TMPDIR=/YOURPATH/tomcat/temp
（/YOURPATH/tomcat 是指tomcat的安装路径）
启动tomcat： service tomcat start
停止tomcat:  service tomcat stop
