Zabbix分布式监控

一、概述

zabbix的三种架构:

1、Server-agent

2、Server-node-agent

3、Server-proxy-agent

Server-proxy-agent：proxy，用于本区域数据收集，并将数据发送给server；

Server-node-agent：node，提供完整的zabbix-server用以建立分布式监控中的层级；

Proxy和Node的比较：

Node本身是一台Server,它有完整的web页面，完整的数据库，它将数据源源不断的传送给Master；

Proxy只有一个proxy的daemon进程，Proxy也有自己的数据库，但它的数据只会保存一定时间，它与Master通信是将一批信息打包后发送到Master，Master将这些数据汇总到Master数据库

Zabbix-Proxy相比Zabbix-Node的优点有以下：

Proxy压力小，数据库只存储一定时间数据；

Proxy压力小，数据不是源源不断获取，减小I/O压力；

架构清晰，易于维护。

Zabbix-Proxy工作特性：

Proxy不会向Server同步Configuration，只会接收数据；

Proxy的数据库定时会将数据传送给Server，Proxy本地数据库只会保存最近没有发送的数据；

二、实验环境

192.168.30.116 OS：Centos6.4 x86_64 zabbix_server.luojianlong.com

192.168.30.115 OS：Centos6.4 x86_64 zabbix_proxy.luojianlong.com

192.168.30.117 OS：Centos6.4 x86_64 node1.luojianlong.com

192.168.30.119 OS：Centos6.4 x86_64 node2.luojianlong.com

首先安装zabbix_server

[[email protected]_server ~]

# yum -y localinstall  zabbix-2.0.8-3.el6.x86_64.rpm zabbix-get-2.0.8-3.el6.x86_64.rpm zabbix-server-2.0.8-3.el6.x86_64.rpm zabbix-server-mysql-2.0.8-3.el6.x86_64.rpm zabbix-web-2.0.8-3.el6.noarch.rpm zabbix-web-mysql-2.0.8-3.el6.noarch.rpm

# 安装数据库，web界面就省略了，前面几篇博客有介绍

在zabbix_proxy 上面安装mysql

[[email protected]_proxy ~]# yum -y install mysql-server

[[email protected]_proxy ~]# service mysqld start
# 创建数据库

mysql> create database zabbix_proxy character set utf8;
Query OK, 1 row affected (0.00 sec)

mysql> grant all on zabbix_proxy.* to 'zbxuser'@'192.168.30.%' identified by '123456';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

安装zabbix_proxy

1	`[[email protected]_proxy ~]# yum -y localinstall zabbix-2.0.8-3.el6.x86_64.rpm zabbix-proxy-2.0.8-3.el6.x86_64.rpm zabbix-proxy-mysql-2.0.8-3.el6.x86_64.rpm`

导入数据库脚本

1	`[[email protected]_proxy ~]# mysql -u zbxuser -p123456 -h 192.168.30.115 zabbix_proxy < /usr/share/doc/zabbix-proxy-mysql-2.0.8/create/schema.sql`

修改zabbix_proxy配置文件

[[email protected]_proxy ~]# vi /etc/zabbix/zabbix_proxy.conf
Hostname=192.168.30.115
DBHost=192.168.30.115
DBName=zabbix_proxy
DBUser=zbxuser
DBPassword=123456
Server=192.168.30.116

[[email protected]_proxy ~]# service zabbix-proxy start
Starting Zabbix proxy:                                     [  OK  ]

[[email protected]_proxy ~]# ss -antpl  | grep zabbix

在node1,node2上分别安装zabbix_agent

[[email protected] ~]# yum -y localinstall zabbix-2.0.8-3.el6.x86_64.rpm zabbix-sender-2.0.8-3.el6.x86_64.rpm zabbix-agent-2.0.8-3.el6.x86_64.rpm
