Zabbix----LNMP架构基础上zabbix监控平台部署

LNMP架构基础上zabbix监控平台部署！

前言

一：zabbix部署

• 主机分配

主机	IP地址	部署服务
server	192.168.233.136	LNMP、zabbix
client	192.168.233.137	zabbix代理

1.1：开局优化

• 关闭防火墙、网络管理、主机名修改（server、client），仅展示server操作

  [root@192 ~]# hostnamectl set-hostname server
  [root@192 ~]# su
  [root@server ~]# 
  [root@server ~]# systemctl stop firewalld && systemctl disable firewalld
  Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
  Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
  [root@server ~]# setenforce 0 && sed -i "s/SELINUX=*/SELINUX=disabled/g" /etc/selinux/config
  [root@server ~]# systemctl stop NetworkManager && systemctl disable NetworkManager
  Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service.
  Removed symlink /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service.
  Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.
  Removed symlink /etc/systemd/system/network-online.target.wants/NetworkManager-wait-online.service.
  

1.2：LNMP安装环境（使用yum安装的方式）

• nagios是一款比较老的监控工具，但是因为插件太多，不是主流

  cacti是一款图形化的监控分析工具

  zabbix是基于web界面的提供分布式功能的监控工具，监控上线是300-500台

  zabbix可以监控网络设备（例如思科、华为等）、服务器（例如IBM、联想、戴尔等）、应用监控（Apache、MQ、中间件、Tomcat等）和服务（HTTP、https、nginx、ssl等）等监控

  zabbix使用的最稳定的版本是4.0，LTS是指测试，5.0版本在官网下载的时候比4.0版本多了一个nginx服务器的选择

• 1、安装nginx

  [root@server ~]# wget 
   http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm	'//下载nginx软件包'
  [root@server ~]# vim /etc/yum.repos.d/nginx.repo	'//编辑yum源'
  [nginx-stable]
  name=nginx stable repo
  baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
  gpgcheck=0
  enabled=1
  [root@server ~]# yum clean all
  已加载插件：fastestmirror, langpacks
  正在清理软件源： base extras nginx-stable updates
  Cleaning up list of fastest mirrors
  [root@server ~]# yum makecache	'//建立yum缓存'
  [root@server ~]# systemctl start nginx
  [root@server ~]# systemctl enable nginx
  Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
  

• 网页测试：发现nginx搭建成功

  

• 2、安装mysql（mariadb）

  [root@server ~]# yum -y install mariadb-server mariadb
  [root@server ~]# systemctl start mariadb.service 
  [root@server ~]# systemctl enable mariadb.service 
  Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
  [root@server ~]# netstat -ntap |grep 3306
  tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN      95170/mysqld  
  '//接下来执行mysql安全配置向导'
  [root@server ~]# mysql_secure_installation
  
  NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
        SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!
  
  In order to log into MariaDB to secure it, we'll need the current
  password for the root user.  If you've just installed MariaDB, and
  you haven't set the root password yet, the password will be blank,
  so you should just press enter here.
  
  Enter current password for root (enter for none): 	'//初次运行直接回车'
  OK, successfully used password, moving on...
  
  Setting the root password ensures that nobody can log into the MariaDB
