zabbixインストール
zabbixユーザーとグループの作成
[root@CoVb ~]# groupadd --system zabbix
[root@covb ~]# useradd --system -g zabbix -d /usr/lib/zabbix -s /sbin/nologin -c "Zabbix Monitoring System" zabbix
[root@covb ~]# cat /etc/group | grep zabbix
zabbix:x:995:
[root@covb ~]# cat /etc/passwd | grep zabbix
zabbix:x:997:995:Zabbix Monitoring System:/usr/lib/zabbix:/sbin/nologin
