解决方案是：
把gpgcheck=0改为gpgcheck=1
如下：
# cat /etc/yum.repos.d/zabbix.repo [zabbix] name=Zabbix Official Repository - $basearch baseurl=http://repo.zabbix.com/zabbix/2.4/rhel/6/$basearch/ enabled=1 #gpgcheck=1 gpgcheck=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX [zabbix-non-supported] name=Zabbix Official Repository non-supported - $basearch baseurl=http://repo.zabbix.com/non-supported/rhel/6/$basearch/ enabled=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX gpgcheck=1
