ZABBIX 설치하는 방법

◆ [설치환경]

■ 릴리즈 설치 테스트 : 2017년 4월 07일

□ CentOS 7 64bit [ 제가 포스팅한 설치이후 환경에서 작업 ]

□ Kernel 4.10.X ↑ [ 해당서버는 최신 커널을 이용합니다. 기존커널에서 작업하셔도 됩니다. ]

□ 일부 설정이나 경로가 다를 수 있습니다. 실서버가 아닌 VMware 환경에서 작업이 이루어 집니다.

□ Zabbix 3.2.X ↑ YUM설치 버전입니다.

ZABBIX란?

간단하게 말하면 네트워크나 서버(가상)등을 포함한 서비스들을 감시하고 실시간으로 자원을 체크하여 관리자에게 신속히 알리기위한 네트워크 관리 솔루션 소프트웨어 입니다. zabbix 에이전트를 Unix, Linux, Windows 등의 OS에 설치하여 CPU,MEM,파일시스템(용량),특정 TCP 등을 포함한 많은 정보를 포함하여 감시를 할수 있으며 장애대비 모니터링으로써도 탁월합니다.

해외 소프트웨어이긴하지만 무료 모니터링 오픈소스이며 무료라고 해서 기능이 제한적이거나 하지 않습니다. 거의 우리나라 상용 모니터링 솔루션과 비교해도 될만큼 그 기능이 다양하며 접근성이 용이합니다. 필요하다면 솔루션업체에 상담 및 일정 비용을 지불하여 원격지원을 받을수도 있습니다. ~~(회화 가능시..)~~

■ Zabbix 3.2 설치

1. Yum 설치를 위해 EPEL 저장소 추가

BASH

[root@localhost ~]# yum install epel-release -y

Installed: epel-release.noarch 0:7-9 Complete!

[root@localhost ~]# rpm -ivh http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm

Updating / installing... 1:zabbix-release-3.2-1.el7 ################################# [100%]############### webtest11.com End #################

[참고]

■ URL : http://repo.zabbix.com/zabbix

접속을 하면 버전별로 파일이 업로드가 되어있습니다. 설치할려는 버전에 맞게 RPM 정보를 가져오면 됩니다.

2. [ Zabbix / DB(MariaDB) / WEB(Apache) / PHP ] YUM 으로 한번에 설치

BASH

[root@localhost ~]# yum -y install zabbix-server-mysql zabbix-web-mysql mysql mariadb-server httpd php

Installed: httpd.x86_64 0:2.4.6-45.el7.centos mariadb.x86_64 1:5.5.52-1.el7 mariadb-server.x86_64 1:5.5.52-1.el7 php.x86_64 0:5.4.16-42.el7 zabbix-server-mysql.x86_64 0:3.2.4-2.el7 zabbix-web-mysql.noarch 0:3.2.4-2.el7 ( 각 설치 버전 참고 )

3. DB(MariaDB) 실행 및 설정

□ DB 실행 및 프로세스 확인

BASH

[root@localhost ~]# systemctl start mariadb
[root@localhost ~]# systemctl enable mariadb
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

[root@localhost ~]# ps -ef |grep mysql
mysql     12650      1  0 11:34 ?        00:00:00 /bin/sh /usr/bin/mysqld_safe --basedir=/usr
mysql     12809  12650  1 11:34 ?        00:00:00 /usr/libexec/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --log-error=/var/log/mariadb/mariadb.log --pid-file=/var/run/mariadb/mariadb.pid --socket=/var/lib/mysql/mysql.sock
root      12861  12260  0 11:34 pts/0    00:00:00 grep --color=auto mysql

□ 기본설정 (DB가 구동된 상태에서 진행가능)

BASH

[root@localhost ~]# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): 패스워드가 없기때문에 엔터

OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation. Set root password? [Y/n] Y (DB ROOT 패스워드 설정) New password: 패스워드입력 Re-enter new password: 재확인 패스워드입력 Password updated successfully! Reloading privilege tables.. ... Success!

By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] Y (익명의 접근을 막을것인지? 보안을 위해 Y 엔터) ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] Y (DB ROOT 원격을 막을것인지? 보안을 위해 Y 엔터)

... Success! By default, MariaDB comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] Y (Test 용으로 생성된 데이터베이스를 삭제할것인가? Y 엔터)

- Dropping test database... ... Success! - Removing privileges on test database... ... Success! Reloading the privilege tables will ensure that all changes made so far will take effect immediately.

Reload privilege tables now? [Y/n] Y (현재 설정한 값을 적용할것인지? 당연히 Y 엔터)

... Success! Cleaning up... All done! If you've completed all of the above steps, your MariaDB installation should now be secure. Thanks for using MariaDB! (끝)
