篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了zabbix部署（server端）相关的知识，希望对你有一定的参考价值。
Linux下常用的系统监控软件有Nagios、Cacti、Zabbix、Monit等，这些开源的软件，可以帮助我们更好的管理机器，在第一时间内发现，并警告系统维护人员。
今天开始研究下Zabbix，使用Zabbix的目的，是为了能够更好的监控mysql数据库服务器，并且能够生成图形报表，虽然Nagios也能够生成图形报表，但没有Zabbix这么强大。
首先，我们先来介绍下Zabblx：一.Zabbix简介
zabbix是一个基于WEB界面的提供分布式系统监视以及网络监视功能的企业级的开源解决方案。
zabbix由zabbix server与可选组件zabbix agent两部门组成。
zabbix server可以通过SNMP，zabbix agent，ping，端口监视等方法提供对远程服务器/网络状态的监视。
zabbix agent需要安装在被监视的目标服务器上，它主要完成对硬件信息或与操作系统有关的内存，CPU等信息的收集。zabbix的主要特点：
- 安装与配置简单，学习成本低
- 支持多语言（包括中文）
- 免费开源
- 自动发现服务器与网络设备
- 分布式监视以及WEB集中管理功能
- 可以无agent监视
- 用户安全认证和柔软的授权方式
- 通过WEB界面设置或查看监视结果
- email等通知功能
等等
Zabbix主要功能：
- CPU负荷
- 内存使用
- 磁盘使用
- 网络状况
- 端口监视
- 日志监视
zabbix部署
1.环境说明
| 环境 | IP | 需要的应用 |
|---|---|---|
| 服务端 | 192.168.24.168 | LAMP zabbix-serverzabbix-agent |
因为zabbix是由php语言开发的，所以要先部署LAMP架构 来支持php网页
2.zabbix安装
安装依赖包
[[email protected] ~]# yum -y install net-snmp-devel libevent-devel 下载zabbix
[[email protected] ~]# cd /usr/src/
[[email protected] src]# wget https://nchc.dl.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/3.4.12/zabbix-3.4.12.tar.gz 解压
[[email protected] src]# tar xf zabbix-3.4.12.tar.gz
[[email protected] src]# ls
apr-1.6.3 apr-util-1.6.1.tar.bz2 mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz zabbix-3.4.12
apr-1.6.3.tar.bz2 debug php-7.2.8 zabbix-3.4.12.tar.gz
apr-util-1.6.1 kernels php-7.2.8.tar.xz
创建zabbix用户和组
[[email protected] ~]# groupadd -r zabbix
[[email protected] ~]# useradd -r -g zabbix -M -s /sbin/nologin zabbix配置zabbix数据库
[email protected] ~]# mysql -uroot -p
