前言:

而今朋友们对“iptables gui”都比较着重,你们都需要了解一些“iptables gui”的相关文章。那么小编也在网摘上汇集了一些关于“iptables gui””的相关内容,希望小伙伴们能喜欢,同学们一起来学习一下吧!

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

进程

hadoop102节点

hadoop103节点

hadoop104节点

zabbix-agent

zabbix-server

MySQL

zabbix-web

(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 [atguigu@hadoop103 ~]$ sudo rpm -ivh [atguigu@hadoop104 ~]$ sudo rpm -ivh 

(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 - $basearchbaseurl=[zabbix-debuginfo]name=Zabbix Official Repository debuginfo - $basearchbaseurl=[zabbix-non-supported]name=Zabbix Official Repository non-supported - $basearchbaseurl=

(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 - $basearchbaseurl=[zabbix-debuginfo]name=Zabbix Official Repository debuginfo - $basearchbaseurl=[zabbix-non-supported]name=Zabbix Official Repository non-supported - $basearchbaseurl=

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[atguigu@hadoop103 ~]$ sudo yum install zabbix-agent[atguigu@hadoop104 ~]$ sudo yum install zabbix-agent

(2)创建Zabbix

[atguigu@hadoop102 ~]$ mysql -uroot -p000000 -e"create database zabbix character set utf8 collate utf8_bin"

(3)导入Zabbix建表语句

[atguigu@hadoop102 ~]$ zcat /usr/share/doc/zabbix-server-mysql-4.4.10/create.sql.gz | mysql -uroot -p000000 zabbix

(4)配置Zabbix_Server(hadoop102)

[atguigu@hadoop102 ~]$ sudo vim /etc/zabbix/zabbix_server.confDBHost=hadoop102DBName=zabbixDBUser=rootDBPassword=000000

(5)配置Zabbix_Agent(三台节点)

[atguigu@hadoop102 ~]$ sudo vim /etc/zabbix/zabbix_agentd.confServer=hadoop102#ServerActive=127.0.0.1#Hostname=Zabbix server

(6)配置Zabbix_Web时区

[atguigu@hadoop102 ~]$ sudo vim /etc/httpd/conf.d/zabbix.conf## Zabbix monitoring system php web frontend#Alias /zabbix /usr/share/zabbix<Directory "/usr/share/zabbix">    Options FollowSymLinks    AllowOverride None    Require all granted    <IfModule mod_php5.c>        php_value max_execution_time 300        php_value memory_limit 128M        php_value post_max_size 16M        php_value upload_max_filesize 2M        php_value max_input_time 300        php_value max_input_vars 10000        php_value always_populate_raw_post_data -1        php_value date.timezone Asia/Shanghai    </IfModule></Directory>

(7)启动zabbix

[atguigu@hadoop102 ~]$ sudo systemctl start zabbix-server zabbix-agent httpd[atguigu@hadoop102 ~]$ sudo systemctl enable zabbix-server zabbix-agent httpd[atguigu@hadoop103 ~]$ sudo systemctl start zabbix-agent[atguigu@hadoop103 ~]$ sudo systemctl enable zabbix-agent[atguigu@hadoop104 ~]$ sudo systemctl start zabbix-agent[atguigu@hadoop104 ~]$ sudo systemctl enable zabbix-agent

(8)停止zabbix

[atguigu@hadoop102 ~]$ sudo systemctl stop zabbix-server zabbix-agent httpd[atguigu@hadoop102 ~]$ sudo systemctl disable zabbix-server zabbix-agent httpd[atguigu@hadoop103 ~]$ sudo systemctl stop zabbix-agent[atguigu@hadoop103 ~]$ sudo systemctl disable zabbix-agent[atguigu@hadoop104 ~]$ sudo systemctl stop zabbix-agent[atguigu@hadoop104 ~]$ sudo systemctl disable zabbix-agent

(9)连接zabbix_web数据库。访问

(10)检查配置

(11)配置数据库

(12)配置zabbix-server

(13)登录zabbix,用户名admin,密码zabbix

Zabbix使用

(1)创建主机

(2)配置Host

(3)查看新增Host。重复以上步骤添加103,104

(4)创建监控项

(5)配置监控项

(6)查看配置的监控项

(7)查看监控最新数据

(8)创建触发器

(9)创建动作

申请邮箱

(1)点击管理/报警媒介类型/Email

(2)编辑邮箱

(3)测试email

(4)email绑定邮件收件人

测试

(1)关闭集群中的HDFS,会有如下效果

[atguigu@hadoop102 hadoop-3.1.3]$ sbin/stop-dfs.sh

(2)查看邮件,接收故障信息

(3)查看仪表盘故障信息
