Shell-批量巡检服务器脚本

3212312

文件说明

该Shell脚本旨在针对大量Linux服务器的巡检提供一种相对自动化的解决方案。脚本组成有三部分：shellsh.sh、checksh.sh、file.txt；这三个文件需放在一个文件夹下以root权限执行，缺一不可。

脚本用法

将要巡检的服务器的IP地址和对应的密码全部放入file.txt中保存，每行一个IP对应一个密码即可。然后用如下命令运行：

#./ shellsh.sh file.txt192.168.182.143 123456

其中file.txt可以更换文件名，192.168.182.143为你想保存巡检日志的到哪个服务器的服务器IP，123456为该服务器的密码。

运行结果

运行完后会在192.168.182.143服务器的/tmp目录下升成一个目录，即：GatherLogDirectory这个目录下即存放的是被巡检的服务器的巡检日志，这些日志以被巡检的服务器的IP命名，形如：192.168.182.146.log。在被巡检的服务器上会升成两个目录即：CheckScript、 LocalServerLogDirectory；其中CheckScript中是checksh.sh脚本，LocalServerLogDirectory中存放的是checksh.sh在该服务器上运行后升成的日志。

测试结果

我只在虚拟机上的三台Linux系统上测试过，分别是Ubuntu、RedHat、Kali。运行正常，平均巡检一个服务器花费3分钟。

注：192.168.182.143是被巡检的服务器ip，123456是被巡检的服务器密码。

声明：此脚本将巡检结果用awk和sed以及grep进行了过滤，以便格式化显示和excel进行处理。由于水平有限，如果有大神认为还有更好的解决方案或者这个脚本还有改进的地方，请指出。我们大家共同学习，共同进步。
