目录
一、脚本要求
二、检查本地系统环境
1.检查系统版本
2.检查系统内核版本
三、编写disk.sh脚本
1.创建脚本目录
2.编写disk.sh脚本
3.执行测试脚本
四、查看脚本执行日志文件
五、本次实践总结
1.脚本定时执行
2.实践总结
一、脚本要求
1.监控磁盘所有分区下的磁盘使用率。
2.磁盘使用率超过60%的提醒。
3.磁盘使用率超过80%的进行警告。
4.将执行结果写入到日志文件中。
5.显示每个分区的挂载目录下具体到二级目录的空间使用大小。
6.每天的凌晨左右定时执行该脚本。
二、检查本地系统环境
1.检查系统版本
[root@jeven ~]# cat /etc/centos-release CentOS Linux release 7.6.1810 (Core)
2.检查系统内核版本
[root@jeven ~]# cat /etc/centos-release CentOS Linux release 7.6.1810 (Core)
三、编写disk.sh脚本
1.创建脚本目录
[root@jeven ~]# mkdir -p /data/scripts [root@jeven ~]# cd /data/scripts/ [root@jeven scripts]# ls
2.编写disk.sh脚本
[root@jeven scripts]# cat disk.sh #!/bin/bash ########################################################## #File Name:disk.sh #Version:V1.0 #Aurhor:jqzheng #Emali:[email protected] #Created Time:2023-02-14 14:36:26 #Description: ########################################################## #监控系统磁盘空间余量不足的情况 ############### 一、定义变量 ########## DATE=$(date '+%m%d%y') #Date for report file ############### 二、将脚本执行脚本导入日志文件 ############ exec > disk_space_$DATE.rpt #Make report file STDOUT ############ 三、检查磁盘空间使用率 ########### echo "检查磁盘空间使用率" while true do # 检查磁盘空间使用率 df -h | grep -vE '^Filesystem|tmpfs|cdrom' | awk '{ print $5 " " $1 " " $6}' | while read output; do # 获取磁盘使用率 usep=$(echo $output | awk '{ print $1}' | cut -d'%' -f1 ) # 获取磁盘名称 partition=$(echo $output | awk '{ print $2 }' ) # 如果磁盘使用率大于80，发出警告 if [ $usep -ge 60 ]; then echo "磁盘 $partition 使用率 $usep, 空间余量不足,请注意" elif [ $usep -ge 80 ];then echo "磁盘 $partition 使用率 $usep , 空间余量严重不足，警告，请重点关注处理" else echo " 磁盘 $partition $usep, 空间余量正常" fi done # 休眠5秒 sleep 5 echo "####################Top Ten Disk Space Usage###############" #Report header CHECK_DIRECTORIES=" $(df -h | grep -vE '^Filesystem|tmpfs|cdrom' | awk '{ print $6 }')" #CHECK_DIRECTORIES=" /home " for DIR_CHECK in $CHECK_DIRECTORIES #Loop to du directories do echo "" echo "The $DIR_CHECK Directory:" #Directory header # # Create a listing of top ten disk space users in this dir du -Sh $DIR_CHECK 2>/dev/null | sort -rn | sed '{11,$D; =}' | sed 'N; s/ / /' | gawk '{printf $1 ":" " " $2 " " $3 " "}' # done #End of loop # exit done
3.执行测试脚本
sh disk.sh
四、查看脚本执行日志文件

五、本次实践总结
1.脚本定时执行
[root@jeven scripts]# crontab -l 01 0 * * * sh /data/scripts/disk.sh
2.实践总结
1.可根据自身实际状况修改脚本内容。 2.可不断优化脚本内容，达到更加理想的效果。 3.运行脚本前，需提前多次测试脚本是否正常，满足功能需求。
