Centos - LibreNMS 설치 하기 :: 모니터링 서비스

 

 

설치 환경

OS: Centos 7.9

TOOL : VMware

DB : MariaDB

---

모니터링이 가능한 프로그램 LibreNMS 설치 입니다.

설치 순서는 여러 경우로 해봤으나 해당 순서가 가장 최적화되었다고 생각해 정리했습니다.

 

---

1. MariaDB 설치

 

1-1. respo 작성

vi /etc/yum.repos.d/MariaDB.repo

↓ 아래 내용 작성 ↓ 

# MariaDB 10.2 CentOS repository list - created 2018-01-11 07:40 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.2/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

 

*LibreNMS는 Mariadb 10.2 이상 지원합니다.

그러므로 최소 10.2 설치를 위해 respo 작성 하였습니다.

 

2-2. 설치

yum install epel-release yum-utils  -y


yum install mariadb mariadb-server  -y

*오류 발생!
GPG key retrieval failed: [Errno 14] curl#60 - "Peer's Certificate has expired."
-> rpm --import http://yum.mariadb.org/RPM-GPG-KEY-MariaDB
