zabbix自动发现和自动注册

配置zabbix自动发现和自动注册。

一、自动发现

1. 配置网络发现规则

配置动作

配置操作

2. 配置agent

修改三个参数
[[email protected] ~]# vim /etc/zabbix/zabbix_agent2.conf
### Option: Server
Server=192.168.43.116

##### Active checks related
ServerActive=192.168.43.116

### Option: Hostname
Hostname=node2

3. 验证自动发现

注意：解决zabbix自动发现主机后主机名称是IP地址的问题
解决方法：dns支持，或者配置hosts解析，否则默认是IP地址。

配置host解析

[[email protected] ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.43.112 node2
192.168.43.116 zabbix

[[email protected] ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.43.112 node2
192.168.43.116 zabbix

删除发现出的主机;服务端，客户端重启

[[email protected] ~]# systemctl restart zabbix-server.service 
[[email protected] ~]# systemctl restart zabbix-agent2.service 

二、自动检测

先将自动发现暂停，防止干扰（在同一网段）
配置agent

[[email protected] ~]# yum install https://mirrors.aliyun.com/zabbix/zabbix/5.4/rhel/7/x86_64/zabbix-agent2-5.4.0-8.el7.x86_64.rpm

[[email protected] ~]# vim /etc/zabbix/zabbix_agent2.conf
### Option: Server
Server=192.168.43.116

##### Active checks related
ServerActive=192.168.43.116

### Option: Hostname
Hostname=node3

[[email protected] ~]# systemctl enable --now zabbix-agent2.service 
Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-agent2.service to
/usr/lib/systemd/system/zabbix-agent2.service.

1. 配置自动注册
