服务器巡检脚本

定位

服务器安全巡检脚本，挺不错的，不熟悉linux的，可以直接使用，方便，脚本如下：

#!/bin/bash

#参数定义

date=`date +"%Y-%m-%d-%H:%M:%S"`

centosVersion=$(awk '{print $(NF-1)}' /etc/redhat-release)

VERSION=`date +%F`

#日志相关

LOGPATH="/tmp/awr"

[ -e $LOGPATH ] || mkdir -p $LOGPATH

RESULTFILE="$LOGPATH/HostCheck-`hostname`-`date +%Y%m%d`.txt"



#调用函数库

[ -f /etc/init.d/functions ] && source /etc/init.d/functions

export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

source /etc/profile





#root用户执行脚本

[ $(id -u) -gt 0 ] && echo "请用root用户执行此脚本！" && exit 1
