Shell 腳本實現自動化循環刪除進程

問題：

服務器中了木馬，每隔幾十秒就會自動啓動一個腳本進程，佔用CPU

 

解決方式：

寫一個 shell 腳本，定時清理木馬進程

# kill_macron.sh 
#!/bin/bash

sleep_time=10
int=1
while(($int<1000))
do
  echo "===== `date` ====="
  pid=`ps -aux |grep "Macron"|grep -v "grep" |awk '{print $2}'`
  wc=`ps -aux |grep "Macron"|grep -v "grep" |awk '{print $2}'|wc -l`
  #echo "wc = " $wc
  if [ $wc -ne "0" ];then
    echo "kill -9 $pid"
    kill -9 $pid
  fi
  sleep $sleep_time
done

再寫啓動進程腳本以及停止進程腳本：

# start.sh
# /bin/bash

nohup sh ./kill_macron.sh > kill_log.log  &
tail -f ./kill_log.log

# stop.sh
# /bin/bash

pid=`ps -aux |grep "kill_macron"|grep -v "grep" |awk '{print $2}'`
wc=`ps -aux |grep "kill_macron"|grep -v "grep" |awk '{print $2}'|wc -l`

if [ $wc -ne "0" ];then
  echo "kill -9 $pid"
  kill -9 $pid
fi

ps -ef|grep "kill_macron"
