簡介
zabbix是一個基于WEB界面的提供分布式網絡監視功能的企業級的開源解決方案。相對于cacti和nagios而言，zabbix最大的特點是分布式監控，自動發現，自定義監控項目。
一、監控系統所具備的四個要素
1、數據采集
zabbix采集數據的手段有SNMP、zabbix的Agent、IPMI agent、web monitoring、database monitoring，Internal check、calculated monitoring、custom command monitoring、ping或端口檢查等。
2、數據存儲
zabbix將數據存儲在RDBMS中。
3、數據展示
zabbix使用php開發的程序進行繪圖。
4、事件報警
zabbix通知機制有：E-mail、SMS、Jabber、Chat message、Command execution。
二、Zabbix組件概述
zabbix-serve：負責接收agent發送的報告信息，所有配置、統計數據及操作數據都有此組件組織進行；
database：用于存儲配置信息和zabbix收集的數據
web-interface：zabbix的GUI接口，通常與server運行在同一臺主機上；
proxy：可選組件，常用于分布式監控環境中，代替server收集其他被監控端的監控數據，并統一發送到server端。
Agent：部署在被監控主機上，負責收集本地數據發往server或proxy端。
三、zabbix的術語
主機（host）：要監控的網絡設備統稱；
主機組（host group）：主機的邏輯容器，可以包含主機和模板；
監控項（item）：一個特定監控指標和對應的數據，每個item由key進行標示；
trigger（觸發器）：一個表達式，用于評估某監控對象的某個特定的item所接收的數據是否在合理范圍內，即閾值，狀態分為“OK”和“problem”。
事件（event）：發生的一個值得關注的事情，如：觸發器的狀態轉變，新的agent上線或自動發現等操作。
動作：對于指定的event發生以后所采定義的處理方法，如發送通知或報警；
報警升級（escalation）：發送警告信息的方案，如果在定義內的警告次數之內沒有處理，將向上級發送報警短信；
媒介（media）：發送通知的手段，如Email、SMS、Jabber等。
通知（notification）：通過媒介向用戶發送某事件的信息。
四、一鍵安裝腳本
說明：此腳本只適用與RHEL6.x系列；Nginx版本為1.6最新穩定版；PHP為5.4最新版；Mysql為5.5最新穩定版；Zabbix暫時為2.4最新版。
只要你能連上網絡，只要你會運行腳本。那你就會完成zabbix的部署安裝了,內嵌yum源及LNMP及zabbix的下載安裝??！真正的實現一步到位?。?/p>
#!/bin/bash
# install Nginx 1.6.2 + mysql5.5.x + PHP-FPM 5.4.x + Zabbix 2.4.4 automatically.

五、配置WEB頁面
地址：IP地址
至此zabbix一鍵部署安裝就完成了，請多提意見！謝謝

最后chkconfig mysql on少個d 最小化安裝需要安裝下wget 其他ok 速度很快。
@xuyilin：這個平臺非管理員，文章一旦提交就暫時無法修改了，謝謝你的提示！
