Zabbix를 설치 하기전에 사전 설치 한다.
[Linux - UTIL] zabbix - 사전 작업
zabbix를 설치하기에 전에 사전에 설정한다. 환경 OS : Centos 7.6 (3.10.0-957.el7.x86_64) KVM내 VM machine에서 작업 CPU 2core RAM 16GB (일단 많이 설정하였다) DISK 30GB 설치 방법 Step.1 Web server 설정..
louky0714.tistory.com
Zabbix 설치를 위한 repository를 설정 한다.
[root@zabbix-svr ~]# yum --enablerepo=remi-safe -y install php72-php php72-php-mysqlnd php72-php-gd php72-php-xml php72-php-bcmath php72-php-ldap

[root@zabbix-svr ~]# systemctl restart httpd
Zabbix PKG를 설치 한다.
[root@zabbix-svr ~]# yum -y install zabbix-get zabbix-server-mysql zabbix-web-mysql zabbix-agentZabbix DB를 설정한다.
