大数据技术之Zabbix

 

第1章 Zabbix入门

1.1 Zabbix概述

Zabbix是一款能够监控各种网络参数以及服务器健康性和完整性的软件。Zabbix使用灵活的通知机制,允许用户为几乎任何事件配置基于邮件的告警。这样可以快速反馈服务器的问题。基于已存储的数据,Zabbix提供了出色的报告和数据可视化功能。

1.2 Zabbix 基础架构

 

第2章 Zabbix部署

2.1 集群规划

节点

服务

hadoop102

zabbix-server、zabbix-agent、MySQL、zabbix-web

hadoop103

zabbix-agent

hadoop104

zabbix-agent

2.2 准备工作

2.2.1 关闭防火墙(3台节点,已关闭)

sudo service iptables stop

sudo chkconfig iptables off

2.2.2 关闭SELinux(hadoop102)

1) 修改配置文件/etc/selinux/config

sudo vim /etc/selinux/config

 

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

#     enforcing - SELinux security policy is enforced.

#     permissive - SELinux prints warnings instead of enforcing.

#     disabled - No SELinux policy is loaded.

SELINUX=disabled

# SELINUXTYPE= can take one of these two values:

#     targeted - Targeted processes are protected,

#     mls - Multi Level Security protection.

SELINUXTYPE=targeted

2)重启服务器

sudo reboot

2.3 配置Zabbix yum源(3台节点)

2.3.1 安装yum源

执行以下命令安装yum源

sudo rpm -ivh https://mirrors.aliyun.com/zabbix/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm

2.3.2 修改为阿里云镜像

1)查看原始zabbix.repo文件

sudo cat /etc/yum.repos.d/zabbix.repo

内容如下

[zabbix]

name=Zabbix Official Repository - $basearch

baseurl=http://repo.zabbix.com/zabbix/4.4/rhel/7/$basearch/

enabled=1

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591

 

[zabbix-debuginfo]

name=Zabbix Official Repository debuginfo - $basearch

baseurl=http://repo.zabbix.com/zabbix/4.4/rhel/7/$basearch/debuginfo/

baseurl=http://repo.zabbix.com/non-supported/rhel/7/$basearch/

enabled=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX

gpgcheck=1

2)执行以下命令完成全局替换

sudo sed -i 's/http://repo.zabbix.com/https://mirrors.aliyun.com/zabbix/g' /etc/yum.repos.d/zabbix.repo

3)查看修改之后的zabbix.repo文件

sudo cat /etc/yum.repos.d/zabbix.repo

内容如下

[zabbix]

name=Zabbix Official Repository - $basearch

baseurl=https://mirrors.aliyun.com/zabbix/zabbix/4.4/rhel/7/$basearch/

enabled=1

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591

 

[zabbix-debuginfo]

name=Zabbix Official Repository debuginfo - $basearch

baseurl=https://mirrors.aliyun.com/zabbix/zabbix/4.4/rhel/7/$basearch/debuginfo/

enabled=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591

gpgcheck=1

 

[zabbix-non-supported]

name=Zabbix Official Repository non-supported - $basearch

baseurl=https://mirrors.aliyun.com/zabbix/non-supported/rhel/7/$basearch/

enabled=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX

gpgcheck=1

2.4 安装Zabbix

一个被用于定义问题阈值和“评估”监控项接收到的数据的逻辑表达式。

3.2.3 Action(动作)

一个对事件做出反应的预定义的操作,比如邮件通知。
