linux下清理日志的脚本

标签：linux服务器   清理日志文件   

需求：由于/var分区单独划分，给的分区大小才5G，日志写满了，需要写个脚本定时清理日志文件

#!/bin/bash

##delete log script ,write by xl

LOG_DIR1=/var/log

LOG_DIR2=/var/spool/mail

LOG_DIR3=/var/spool/mqueue

ROOT_UID=0

##Must be use root to run this script

if [ "$UID" -ne "$ROOT_UID" ]

then

  echo "Must be root to run this script."

  exit 1

 fi

cd $LOG_DIR1 || {

   echo "Can not change to necessary dircectory." >&2

   exit 1

  }

#把空设备重定向到文件里面

cat /dev/null > maillog && echo "Logs cleaned up."

cat /dev/null > maillog.1 && echo "Logs cleaned up."

cat /dev/null > maillog.2 && echo "Logs cleaned up."

cd $LOG_DIR2 || {

   echo "Can not change to necessary dircectory." >&2

   exit 1

  }

cat /dev/null > root && echo "Logs cleaned up."

cat /dev/null > stock && echo "Logs cleaned up."

###清除mqueue下的小文件

cd $LOG_DIR3

ls |xargs rm -rf
