참조 : https://www.zabbix.com/download?zabbix=5.0&os_distribution=ubuntu&os_version=20.04&components=agent_2&db=&ws=

$ wget https://repo.zabbix.com/zabbix/5.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_5.0-1+focal_all.deb

$ sudo dpkg -i
zabbix-release_5.0-1+focal_all.deb

$ sudo apt update

$ sudo apt install zabbix-agent2

error 발생

The
following packages have unmet dependencies:

 zabbix-agent2 : Depends: libssl1.1 (>=
1.1.1) but it is not installable

E:
Unable to correct problems, you have held broken packages.

$ sudo echo “deb http://security.ubuntu.com/ubuntu focal-security main” | sudo tee
/etc/apt/sources.list.d/focal-security.list

$ sudo apt update

$ sudo apt install libssl1.1

$ sudo apt install zabbix-agent

 -> 정상설치

$ sudo systemctl restart zabbix-agent

$
sudo systemctl enable zabbix-agent

$ sudo systemctl status
zabbix-agent

$ sudo vi /etc/zabbix/zabbix_agentd.conf

Server=192.168.0.101

ServerActive=192.168.0.101

$ sudo systemctl restart zabbix-agent

6. Zabbix Server GUI 에서 추가

– configuration -> hosts -> create host -> add

-> 템플릿에서 “Linux
by zabbix agent” 추가 필요. “Linux by Zabbix
agent active”와 중복불가.

** agentd port 연결확인

zabbix 서버 -> zabbix 에이전트

root@test01:~#
nc -vz test02 10050

Connection
to test02 (192.168.0.148) 10050 port [tcp/zabbix-agent] succeeded!
