Tomcat集群环境下，重启Tomcat的shell脚本

Shell如下：

#!/bin/bash  
#defined   
export JAVA_HOME=/root/.jenkins/tools/hudson.model.JDK/jdk8  
NUM="$1"  
TOMCAT_HOME="/opt/soft/tomcat_cluster/tomcat_$NUM"  

if [ $NUM = 1 ]  
    then  
        TOMCAT_PORT=8090  
fi  

if [ $NUM = 2 ]  
    then  
        TOMCAT_PORT=8100  
fi  

if [ $NUM = 3 ]  
    then  
        TOMCAT_PORT=8110  
fi  

if [ $NUM = 0 ]  
    then  
        TOMCAT_PORT=8060  
fi  
#shutdown tomcat  
#"$TOMCAT_HOME"/bin/shutdown.sh  
#echo "tomcat shutdown"  
#check tomcat process  
tomcat_pid=`/usr/sbin/lsof -n -P -t -i :$TOMCAT_PORT`  
echo "current :" $tomcat_pid  
while [ -n "$tomcat_pid" ]  
do  
 sleep 5  
 tomcat_pid=`/usr/sbin/lsof -n -P -t -i :$TOMCAT_PORT`  
 echo "scan tomcat pid :" $tomcat_pid  
 if [ -n "$tomcat_pid" ]; then  
   echo "kill tomcat :" $tomcat_pid  
   kill -9 $tomcat_pid  
 fi  
done  
#start tomcat  
cd "$TOMCAT_HOME"  
./bin/startup.sh
