CentOS6.x zabbix客户端 一键安装
简介
zabbix是一个基于WEB界面的提供分布式网络监视功能的企业级的开源解决方案。相对于cacti和nagios而言，zabbix最大的特点是分布式监控，自动发现，自定义监控项目。
一、监控系统所具备的四个要素
1、数据采集
zabbix采集数据的手段有SNMP、zabbix的Agent、IPMI agent、web monitoring、database monitoring，Internal check、calculated monitoring、custom command monitoring、ping或端口检查等。
2、数据存储
zabbix将数据存储在RDBMS中。
3、数据展示
zabbix使用php开发的程序进行绘图。
4、事件报警
zabbix通知机制有：E-mail、SMS、Jabber、Chat message、Command execution。
二、Zabbix组件概述
zabbix-server：负责接收agent发送的报告信息，所有配置、统计数据及操作数据都有此组件组织进行；
database：用于存储配置信息和zabbix收集的数据
web-interface：zabbix的GUI接口，通常与server运行在同一台主机上；
proxy：可选组件，常用于分布式监控环境中，代替server收集其他被监控端的监控数据，并统一发送到server端。
Agent：部署在被监控主机上，负责收集本地数据发往server或proxy端。
三、zabbix的术语
主机（host）：要监控的网络设备统称；
主机组（host group）：主机的逻辑容器，可以包含主机和模板；
监控项（item）：一个特定监控指标和对应的数据，每个item由key进行标示；
trigger（触发器）：一个表达式，用于评估某监控对象的某个特定的item所接收的数据是否在合理范围内，即阈值，状态分为“OK”和“problem”。
事件（event）：发生的一个值得关注的事情，如：触发器的状态转变，新的agent上线或自动发现等操作。
动作：对于指定的event发生以后所采定义的处理方法，如发送通知或报警；
报警升级（escalation）：发送警告信息的方案，如果在定义内的警告次数之内没有处理，将向上级发送报警短信；
媒介（media）：发送通知的手段，如Email、SMS、Jabber等。
通知（notification）：通过媒介向用户发送某事件的信息。
四、一键安装脚本
说明：此脚本只适用与RHEL6.x系列；Nginx版本为1.6最新稳定版；PHP为5.4最新版；Mysql为5.5最新稳定版；Zabbix暂时为2.4最新版。
#!/bin/bash
# install Nginx 1.6.2 + mysql5.5.x + PHP-FPM 5.4.x + Zabbix 2.4.4 automatically.
# Tested on CentOS 6.5
