CentOS下停止Tomcat运行脚本代码

#!/bin/sh
#
# Firstly find the process of the tomcat....
TOMCAT_PROCESS_STR=`ps aux | grep 'java.*tomcat' | grep -v grep`
PROCESS_ARRAY=(${TOMCAT_PROCESS_STR// / })
TOMCAT_PROCESS_ID=${PROCESS_ARRAY[1]}
echo $TOMCAT_PROCESS_ID
#
# Secondly send stop tomcat to see if we can kill it
stoptomcat
sleep 12
#
# Last we'll use kill tomcat process in a looking up loop
for ((a=1;a<=10;a++))
do
 CHECK_STR_LENGTH=0
 TOMCAT_PROCESS_CHECK_STR=`ps aux | grep 'java.*tomcat' | grep -v grep`
 CHECK_STR_LENGTH=${#TOMCAT_PROCESS_CHECK_STR}
# 传递到脚本的参数个数；
 if [ $CHECK_STR_LENGTH != 0 ]
 then
  kill $TOMCAT_PROCESS_ID
  sleep 5
  echo Try to kill tomcat once more...
 else
  echo Tomcat is already killed
  break
 fi
done
#使用两次grep来去除grep自身进程对于查找结果的干扰是非常有技巧的
