一、说明

1、在 Zabbix 7 中创建 Linux 主机的过程主要包括以下几个步骤，从 Zabbix Web 界面添加主机、配置主机参数、关联模板，到最终验证数据采集是否成功。
2、Zabbix Server 能访问 Agent 主机端口，默认 10050；如果使用主动模式或加密通信，确保对应配置一致；
3、本实例我们以 RockyLinux9 为例安装 Agent并添加主机操作。

二、安装 Zabbix Agent2

1、查验Zabbix Server版本：zabbix_server -V

# zabbix_server -V
zabbix_server (Zabbix) 7.0.15

2、安装 zabbix-agent2 包：dnf install -y https://mirrors.aliyun.com/zabbix/zabbix/7.0/rocky/9/x86_64/zabbix-agent2-7.0.13-release1.el9.x86_64.rpm

# dnf install -y https://mirrors.aliyun.com/zabbix/zabbix/7.0/rocky/9/x86_64/zabbix-agent2-7.0.15-release1.el9.x86_64.rpm

Installed:
  zabbix-agent2-7.0.15-release1.el9.x86_64

Complete!

Zabbix Agent 版本建议等于小于服务端版本

3、配置zabbix Agent配置（/etc/zabbix/zabbix_agent2.conf）文件，把Server参数和ServerActive参数都配置Zabbix Server服务器地址，把Hostname参数配置本地主机名。
    Server=172.16.2.11
    ServerActive=172.16.2.11
    Hostname=Agent端的Hostname
4、启动Zabbix Agent并加入自启动：systemctl enable –now zabbix-agent2.service

# systemctl enable --now zabbix-agent2.service
Created symlink /etc/systemd/system/multi-user.target.wants/zabbix-agent2.service → /usr/lib/systemd/system/zabbix-agent2.service.

三、Zabbix Web中添加主机

1、创建主机：数据采集>>主机>>创建主机

2、配置Agent主机基础信息：
    主机名称：Agent主机的IP
    可见的名称：用于前台显示便于辨识的名称
    模版：输入关键词下拉菜单选择（或从右侧“选择”按钮选择）选择“Linux by Zabbix agent”
    主机群组：输入关键词下拉菜单选择（或从右侧“选择”按钮选择）”Linux server”
    接口：点击“添加”选 Agent

3、输入Agent主机的IP后点击“添加”按钮创建主机

4、验证主机生效：看到刚添加的主机的可用性的“ZBX”变成绿色时表示生效并采集到数据
