모니터링 - Zabbix

서버는 CentOS 6.5 에서 RPM 패키지를 이용하여 설치하는 것을 기준으로 설명합니다.

설치에 대한 정보는 기본적으로 Zabbix 공식문서를 참조로 합니다.

https://www.zabbix.com/documentation/2.2/manual/installation/install_from_packages

본격적으로 도입하기에 앞서, 모든 기록은 Zabbix server의 서버시간을 기준으로 기록되므로, 서버는 표준시에 동기화 되어있는것을 권장합니다.

서버 설치

패키지 설치

설치를 위한 공식 레파지토리 등록

rpm -Uvh http://repo.zabbix.com/zabbix/2.2/rhel/6/x86_64/zabbix-release-2.2-1.el6.noarch.rpm

설치 (2014/1/28 기준으로 2.2.1-1)

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

패키지 설치 완료후 레파치토리 비활성화

enabled=1 을 enabled=0 으로 변경

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

DB 설치

MySQL를 설치하고 Zabbix용 DB와 사용자를 작성

MySQL 설치 (CentOS 기본 버전인 5.1.x 설치하여 사용하기로 한다.)

yum install mysql-server
/etc/init.d/mysqld start
/usr/bin/mysql_secure_installation
mysql -u root -p

-(아래 실행)------------------------------------

Zabbix용 DB의 작성

create database zabbix character set utf8;

Zabbix용 사용자 작성

grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix-password';

설정의 반영

FLUSH PRIVILEGES;

exit

------------------------------

Zabbix용 DB스키마와 데이터를 임포트

mysql -uroot -p zabbix < /usr/share/doc/zabbix-server-mysql-2.2.1/create/schema.sql
mysql -uroot -p zabbix < /usr/share/doc/zabbix-server-mysql-2.2.1/create/images.sql
mysql -uroot -p zabbix < /usr/share/doc/zabbix-server-mysql-2.2.1/create/data.sql

zabbix서버의 설정

vi /etc/zabbix/zabbix_server.conf

---(아래를 변경)------------------------------------

DBPassword=

↓

DBPassword=zabbix-password

------------------------------

WEB 설정

서버 부팅시 Zabbix서버의 자동 시작을 설정

chkconfig zabbix-server on

PHP 설정에서 Timezone 설정

vi /etc/php.ini

;date.timezone =

date.timezone = Asia/Seoul

Zabbix WEB UI를 사용하기 위해 Apache를 다시 실행

service httpd restart
