nagios監(jiān)控http（借助腳本）

站在用戶的角度思考問題，與客戶深入溝通，找到武邑網(wǎng)站設(shè)計與武邑網(wǎng)站推廣的解決方案，憑借多年的經(jīng)驗，讓設(shè)計與互聯(lián)網(wǎng)技術(shù)結(jié)合，創(chuàng)造個性化、用戶體驗好的作品，建站類型包括：網(wǎng)站設(shè)計制作、成都網(wǎng)站建設(shè)、企業(yè)官網(wǎng)、英文網(wǎng)站、手機(jī)端網(wǎng)站、網(wǎng)站推廣、國際域名空間、雅安服務(wù)器托管、企業(yè)郵箱。業(yè)務(wù)覆蓋武邑地區(qū)。

修改后的腳本如下（需添加指示燈的狀態(tài)）

# vi httpd.sh

#!/bin/bash

Port=`netstat -ntpl | grep httpd | awk -F[:" "]+ '{print $4}'`
if [ $Port == "80" ];then
echo "OK - http is running"
exit 0
else
echo "CRITICAL - http is down"
/sbin/service httpd restart
exit 2
fi
   
:wq

注：0 指的是狀態(tài)燈綠燈，2指的是紅燈，黃燈不用     并且宕了之后再次check時就能自動重啟
