zabbix简介：
zabbix（音同 zæbix）是一个基于WEB界面的提供分布式系统监视以及网络监视功能的企业级的开源解决方案。
zabbix能监视各种网络参数，保证服务器系统的安全运营；并提供灵活的通知机制以让系统管理员快速定位/解决存在的各种问题。
zabbix由2部分构成，zabbix server与可选组件zabbix agent。
zabbix server可以通过SNMP，zabbix agent，ping，端口监视等方法提供对远程服务器/网络状态的监视，数据收集等功能，它可以运行在Linux，Solaris，HP-UX，AIX，Free BSD，Open BSD，OS X等平台上。
Alexei Vladishev创建了Zabbix项目，当前处于活跃开发状态，Zabbix SIA提供支持.
Zabbix是一个企业级的、开源的、分布式的监控套件
Zabbix可以监控网络和服务的监控状况. Zabbix利用灵活的告警机制，允许用户对事件发送基于Email的告警. 这样可以保证快速的对问题作出相应. Zabbix可以利用存储数据提供杰出的报告及图形化方式. 这一特性将帮助用户完成容量规划.
Zabbix支持polling和trapping两种方式. 所有的Zabbix报告都可以通过配置参数在WEB前端进行访问. Web前端将帮助你在任何区域都能够迅速获得你的网络及服务状况. Zabbix可以通过尽可能的配置来扮演监控你的IT基础框架的角色，而不管你是来自于小型组织还是大规模的公司.
Zabbix是零成本的. 因为Zabbix编写和发布基于GPL V2协议. 意味着源代码是免费发布的.
Zabbix公司也提供商业化的技术支持.

环境说明：
check1为master，check2和check3为分布式slave
[root@check2 ~]# cat /etc/redhat-release CentOS release 6.9 (Final) [root@check2 ~]# uname -a Linux check2 2.6.32-696.16.1.el6.x86_64 #1 SMP Wed Nov 15 16:51:15 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
一、zabbix安装
Zabbix 3.0对PHP的要求最低为5.4，而CentOS6默认为5.3.3，完全不满足要求，故需要利用第三方源，将PHP升级到5.4以上，注意，不支持PHP7
[root@check2 ~]# rpm -ivh http://repo.webtatic.com/yum/el6/latest.rpm [root@check2 ~]# yum -y install php56w php56w-gd php56w-mysql php56w-bcmath php56w-mbstring php56w-xml php56w-ldap [root@check2 ~]# vim /etc/php.ini 889 date.timezone = Asia/Shanghai 663 post_max_size = 32M 375 max_execution_time = 300 385 max_input_time = 300 705 always_populate_raw_post_data = -1
