CentOS下停止Tomcat运行脚本代码

代码验证通过，保留，以备后用

#!/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
