  1. zabbix configuration (환경설정 - zabbix-server 환경설정에 맞추어서 작업 진행 해야합니다. )

  • 환경 설정 작업 전에는 항상 conf 파일 백업 해두는 것이 좋습니다.

 

$ vi /etc/zabbix/zabbix_agentd.conf

 

## 수정 start ##

95 Server=127.0.0.1

→  95 Server=192.168.137.43

 

136 ServerActive=127.0.0.1

→  136 ServerActive=192.168.137.43

 

147 Hostname=Zabbix server

→ 147 Hostname=zabbix.masangsoft.kr

 

## 수정 End ##

 

247 # AllowRoot=0

248 AllowRoot=1   ## 추가 




  1. 기타 (서버 설정마다 다름)

방화벽 설정이 되어있다면 해당 방화벽 설정에 맞게 추가 해줘야합니다.

10050 port 추가 

서버 설정에 맞게 자동 재시작 등록 해줘야 합니다.





  1. 확인

minimal 로 설치 했기 때문에 ifconfig 명령어가 없어 net-tools 설치 해야 합니다.

 

 

ifconfig not found

 

net-tools install



작업 전에 firewalld 를 iptables 변경해 줍니다. 추후 geoip 모듈을 올릴 수도 있고, iptables가 자세한 룰셋 설정시 더 익숙한 이유 입니다.

selinux disabled 도 해주세요.
