[ Zabbix 4.0설치 및 설정 ]

 

 

 

 

 

 

 

 

 

우선 Zabbix Package들을 설치하자.

 

 

rpm -ivh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm

CentOS7 시스템에 Zabbix Repo를 추가한다.

 

yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-get zabbix-agent

Zabbix와 DB, WEB 연동을 위한 설치와 agent, get 설치

 

 

[root@localhost ~]# rpm -ivh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm

[root@localhost ~]# yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-get zabbix-agent

 

 

 

 

 

 

[ Zabbix 테이블 값 데이터베이스에 적용 ]

 

 

- cd /usr/share/doc/zabbix-server-mysql-3.4.6/
- gunzip create.sql.gz

- mysql -u root -p zabbix < create.sql

[root@localhost ~]# cd /usr/share/doc/zabbix-server-mysql-3.4.15/
AUTHORS        ChangeLog      COPYING        create.sql.gz  NEWS           README

[root@localhost ~]# cd /usr/share/doc/zabbix-server-mysql-3.4.15/

[root@localhost zabbix-server-mysql-3.4.15]# gunzip create.sql.gz

[root@localhost zabbix-server-mysql-3.4.15]# mysql -u root -p zabbix < create.sql
Enter password:

 

 

 

 

 

[ Zabbix 서버 설정 ]

 

 

 

 

- vim /etc/zabbix/zabbix_server.conf

[root@localhost zabbix-server-mysql-3.4.15]# vim /etc/zabbix/zabbix_server.conf

 

빨간색 내용을 맨 아래에 추가할 것

 

DBHost=localhost

DBName=zabbix

DBUser=zabbix               

DBPassword=testpw123

 

DBName과 DBUser은 이미 존재하므로 / 기능을 이용하여 찾은 이후에 바꿔주고

DBHost와 DBPassword는 추가한다.

 

 

 

 

 

 

 

zabbix-server의 서비스를 시작하고 매 부팅마다 실행될 수 있도록 설정한다.

 

- systemctl restart zabbix-server

- systemctl enable zabbix-server

- systemctl status zabbix-server

 [ Web client로 Zabbix 접속 ] 

 

이제 Web Client에서 Zabbix로 접속해보자.

 

주소창에 192.168.5.3/zabbix

 

Next step을 누른다.

 

 

OK떴는지 확인 후 Next step을 누른다.

 

 

 

 

DBName, DBUser, Password 등을 기입한다.

Next step을 누른다.

 

 

 

 

 Name은 Zabbix_Monitoring 으로 설정해주었다.

 

 

 

 

최종확인하기

설치 완료

 

 

 

 

 

ID : Admin

PW: zabbix

 

초기 설정값임

 

 

 

 

사람 모양 클릭 -> Language : Korean 으로 변경 ( 우린 한쿡인 )

 

 

 

 

다시 들어와서 Change Password 클릭 후 Password 변경하기

 

 

 

 

 

안바꾼다면 default password인 zabbix로 설정되므로 변경해주어야 타인이 침입하기 힘듬
