shell指令碼實現多臺伺服器自動巡檢

阿新 • • 發佈：2020-11-17

運維服務一個專案二十多臺（或者多臺）伺服器，每天要做伺服器的效能巡檢工作是檢視伺服器的CPU、記憶體、磁碟空間是否在正常值範圍內。像這樣每天或者每個固定時間段都做相同的重複工作，為了簡化重複的工作，我寫了基於liunx伺服器的自動巡檢指令碼，在crontab中設定一個固定時間進行自動執行即可，以減少人工重複勞動的工作。

環境：

我的專案上主要伺服器是LINUX和AIX兩種伺服器，總數在30臺左右。現在的工作量是每週巡檢兩次，都是手動登入到每臺伺服器使用相應的命令檢視伺服器效能引數。

思路：

1、所有的伺服器之間的網路都是在同一個區域網內，所有網路兩兩相通。

2、在其中選擇一臺效能相對較好或者是伺服器執行壓力較小的伺服器，作為巡檢伺服器。

3、通過這一伺服器來實現對其他伺服器的巡檢，然後把巡檢結果記錄到巡檢伺服器上。

4、每臺伺服器巡檢結果都以時間和ip做命名用來區分，最後將所有巡檢結果壓縮打包。

5、每次維護人員只需要定時去取這個壓縮包檢視最後結果即可，免去了對每臺伺服器都需要登入和輸入相同的命令進行檢視。

檔案說明

該Shell指令碼旨在針對大量Linux伺服器的巡檢提供一種相對自動化的解決方案。指令碼組成有三部分：shellsh.sh、checksh.sh、file.txt；這三個檔案需放在一個資料夾下以root許可權執行，缺一不可。

指令碼用法：

將要巡檢的伺服器的IP地址和對應的密碼全部放入file.txt中儲存，每行一個IP對應一個密碼即可。然後用如下命令執行：

./ shellsh.sh file.txt192.168.182.143 123456

其中file.txt可以更換檔名，192.168.182.143為你想儲存巡檢日誌的到哪個伺服器的伺服器IP，123456為該伺服器的密碼。

執行結果：

執行完後會在192.168.182.143伺服器的/tmp目錄下升成一個目錄，即：GatherLogDirectory這個目錄下即存放的是被巡檢的伺服器的巡檢日誌，這些日誌以被巡檢的伺服器的IP命名，形如：192.168.182.146.log。在被巡檢的伺服器上會升成兩個目錄即：CheckScript、 LocalServerLogDirectory；其中CheckScript中是checksh.sh指令碼，LocalServerLogDirectory中存放的是checksh.sh在該伺服器上執行後升成的日誌。

測試結果：

我只在虛擬機器上的三臺Linux系統上測試過，分別是Ubuntu、RedHat、Kali。執行正常，平均巡檢一個伺服器花費3分鐘。
