Linux巡检脚本-Toy模板网

这篇具有很好参考价值的文章主要介绍了Linux巡检脚本。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

做运维的朋友都知道，大家经常要对一些系统做月度维护或者自查，在这个过程中，如果只是小工作量的查询，进入系统直接输入命令即可。但是如果说要查询的系统很多，每个系统中要查询的项目也很多，那么每次都要一次一次地输入命令就很麻烦。所以建议大家在获得管理员的许可的前提下，可以使用脚本。

下面是我写的linux中常见的检查项的脚本，大家可以测试使用，如果有其他的检查项，按照上面的格式添加进去就好。

#!/bin/bash

echo "" > /tmp/shell/xunjian.txt
echo "1  cpu mem " >> /tmp/shell/xunjian.txt
echo "" >> /tmp/shell/xunjian.txt
top -bn 1 | head -n 15  >> /tmp/shell/xunjian.txt

echo "" >> /tmp/shell/xunjian.txt
echo "2  df -h " >> /tmp/shell/xunjian.txt
echo "" >> /tmp/shell/xunjian.txt
df -h >> /tmp/shell/xunjian.txt

echo "" >> /tmp/shell/xunjian.txt
echo "3  hostname  " >> /tmp/shell/xunjian.txt
echo "" >> /tmp/shell/xunjian.txt
hostname  >> /tmp/shell/xunjian.txt

echo "" >> /tmp/shell/xunjian.txt
echo "4  ps aux|more  " >> /tmp/shell/xunjian.txt
echo "" >> /tmp/shell/xunjian.txt
ps aux| more |head -n 10  >> /tmp/shell/xunjian.txt

echo "" >> /tmp/shell/xunjian.txt
echo "5  ifconfig  " >> /tmp/shell/xunjian.txt
echo "" >> /tmp/shell/xunjian.txt
ifconfig  >> /tmp/shell/xunjian.txt

echo "" >> /tmp/shell/xunjian.txt
echo "6  vmstat 1  1  " >> /tmp/shell/xunjian.txt
echo "" >> /tmp/shell/xunjian.txt
vmstat 1  1 >> /tmp/shell/xunjian.txt

echo "" >> /tmp/shell/xunjian.txt
echo "7  date  " >> /tmp/shell/xunjian.txt
echo "" >> /tmp/shell/xunjian.txt
date >> /tmp/shell/xunjian.txt

查询结果如下所示：
