在上篇文章演示了Zabbix监控Windows 主机,这篇文章将演示Zabbix监控Linux主机配置操作。

0x01 准备工作

  • 准备好需要被监控Linux主机需与Zabbix Server正常通信

    Zabbix Server

    OS:CentOS 7.4

    Hostname:Zabbix

    IP:172.16.252.100

    已安装部署好Zabbix 5.0.6

    Zabbix Client

    OS:CentOS 7.4

    Hostname:Lab-client

    IP:172.16.252.111

0x02 安装Zabbix Agent

  • 安装Zabbix 5.0 yum源

  • 修改zabbix-agent配置文件
  1. [root@lab-client ~]# vim /etc/zabbix/zabbix_agentd.conf
  2. #修改117行
  3. Server=172.16.252.100 #此处填写Zabbix Server的IP地址
  4. #修改158行
  5. ServerActive=172.16.252.100 #此处填写Zabbix Server的IP地址
  6. #修改169行
  7. Hostname=lab-client #此处填写被监控主机电脑名
  • 启动zabbix_agent服务
  1. #关闭防火墙此处演示，生产环境可放行10050端口即可
  2. [root@lab-client ~]# systemctl disable firewalld
  3. Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
  4. Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
  5. #启动Zabbix_agent服务并添加到自动启动
  6. [root@lab-client ~]# systemctl start zabbix-agent.service && systemctl enable zabbix-agent.service
  7. Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-agent.service to /usr/lib/systemd/system/zabbix-agent.service.
  8. #查看zabbix_agent是否启动

0x03 控制端新增被监控主机

  • 进入控制端后，首先新增主机群组Linux-CentOS

88dd1af8f58a08f_1_post.png

  • 创建CentOS模板群组，将上一步新建的Linux-CentOS主机群组加入，并链接到Template OS Linux by Zabbix agent基础模板 (此处演示用，使用自带基础模板)

88c7f7a8b853d4e_1_post.png

  • 新增主机，并将lab-client主机添加到Linux-CentOS主机群组中

8885f8edaa828b2_1_post.png

88f6a152d8285c0_1_post.png

  • 看到主机状态中ZBX变绿了，即证明安装成功，可以被正常监控

8899e84482adfd5_1_post.png

  • 验证查看主机运行状态图形显示

8857aa80e8d8cff_1_post.png

可以正常看到主机当前CPU运行状态，到此已完成通过Zabbix监控Linux主机配置动作，其他更深入的监控项以及触发器操作后续会依次实验。
