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。

Zabbix部署

（1）准备工作,关闭集群

如果集群开启，先关闭集群。因为安装完毕Zabbix后，需要重启虚拟机。

[atguigu@hadoop102 ~]$ cluster.sh stop

关闭防火墙（3台节点，已关闭）

[atguigu@hadoop102 ~]$ sudo service iptables stop
[atguigu@hadoop102 ~]$ sudo chkconfig iptables off


[atguigu@hadoop103 ~]$ sudo service iptables stop
[atguigu@hadoop103 ~]$ sudo chkconfig iptables off


[atguigu@hadoop104 ~]$ sudo service iptables stop
[atguigu@hadoop104 ~]$ sudo chkconfig iptables off

（2）关闭防火墙

[atguigu@hadoop102 ~]$ sudo service iptables stop
[atguigu@hadoop102 ~]$ sudo chkconfig iptables off


[atguigu@hadoop103 ~]$ sudo service iptables stop
[atguigu@hadoop103 ~]$ sudo chkconfig iptables off


[atguigu@hadoop104 ~]$ sudo service iptables stop
[atguigu@hadoop104 ~]$ sudo chkconfig iptables of

（3）关闭SELinux

[atguigu@hadoop102 ~]$ 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

（4）重启服务器

[atguigu@hadoop102 ~]$  sudo reboot

配置yum源

（1）从阿里云镜像中下载zabbix安装包，并执行安装命令。

[atguigu@hadoop102 ~]$ sudo rpm -ivh https://mirrors.aliyun.com/zabbix/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm


[atguigu@hadoop103 ~]$ sudo rpm -ivh https://mirrors.aliyun.com/zabbix/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm


[atguigu@hadoop104 ~]$ sudo rpm -ivh https://mirrors.aliyun.com/zabbix/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm

（2）修改阿里云镜像101,102,103三台节点，依次执行以下步骤

[atguigu@hadoop102 ~]$ sudo cat /etc/yum.repos.d/zabbix.repo

查看内容如下

[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/
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591
gpgcheck=1


[zabbix-non-supported]
name=Zabbix Official Repository non-supported - $basearch
baseurl=http://repo.zabbix.com/non-supported/rhel/7/$basearch/
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
gpgcheck=1

（3）执行以下命令完成全局替换

[atguigu@hadoop102 ~]$ sudo sed -i 's/http://repo.zabbix.com/https://mirrors.aliyun.com/zabbix/g' /etc/yum.repos.d/zabbix.repo

（4）查看修改后的zabbix.repo文件

[atguigu@hadoop102 ~]$ sudo cat /etc/yum.repos.d/zabbix.repo


[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

安装Zabbix

（1）在hadoop102、hadoop103、hadoop104三台节点分别执行以下安装命令

[atguigu@hadoop102 ~]$ sudo yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent
