客户这里，有很多linux主机，都是centos7的，我们需要定期每天对linux主机进行巡检，然后把巡检结果集中保存，方便对主机状态检查。
为了巡检工作需要，需要在linux主机上编写巡检脚本，配置rsync客户端。、

linux巡检脚本

我收集了一个巡检脚本，如下所示：

#!bin/bash
#主机信息每日巡检

IPADDR=$(ifconfig eth0 | grep ‘&;inet&;‘ | awk ‘{print $2}‘)
#环境变量PATH没设好，在cron里执行时有很多命令会找不到
export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
source /etc/profile

[ $(id -u) -gt 0 ] && echo "请用root用户执行此脚本！" && exit 1
centosVersion=$(awk ‘{print $(NF-1)}‘ /etc/redhat-release)
VERSION="2018.08.28"

#日志相关
LOGPATH="$PROGPATH/var/log/HostDailyCheck"
[ -e $LOGPATH ] || mkdir $LOGPATH
RESULTFILE="$LOGPATH/HostDailyCheck-$IPADDR-`date +%Y%m%d`.txt"
