安全殺死TOMCAT進程的Linux Shell指令碼,由於此指令碼裡面用到了很多不錯的指令碼編程技巧,在此分享給大家;

#
# 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<=100;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}
  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

特別值得一提的是:

TOMCAT_PROCESS_STR=`ps aux | grep 'java.*tomcat' | grep -v grep`

使用兩次grep來去除grep自身進程對於尋找結果的幹擾是非常有技巧的。
