报错信息：
[root@localhost ~]# wget https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/5.0/rhel/6/x86_64/zabbix-agent-5.0.0-1.el6.x86_64.rpm [root@localhost ~]# rpm -ivh zabbix-agent-5.0.0-1.el6.x86_64.rpm 警告：zabbix-agent-5.0.0-1.el6.x86_64.rpm: 头V4 RSA/SHA512 Signature, 密钥 ID a14fe591: NOKEY 错误：依赖检测失败： libpcre.so.0()(64bit) 被 zabbix-agent-5.0.0-1.el6.x86_64 需要
解决方法：
使用Zabbix 5.0 Yum源文件安装zabbix-agent 5.0软件，并且将gpgcheck=1修改为gpgcheck=0，防止出现“获取GPG密钥失败”报错。
安装Zabbix Yum源仓库
[root@localhost ~]# rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm [root@localhost ~]# yum clean all
修改Zabbix 5.0 Yum源配置文件：
