按照开发同学提供的文档，以下列方式执行： echo "rocommunity public" >> /etc/snmp/snmpd.conf systemctl restart snmpd.service 即在配置文件中添加"rocommunity public"后，并重启服务，snmpwalk -v1 -c public localhost执行正确，会返回一组snmp的数据，该命令执行没问题； 但是查询服务状态存在的报错"Can't find directory of RPM packages"仍然存在，这个是否有问题？ 执行结果如下： [root@iZbp1f0r7cq40w7pws3kfpZ ~]# echo "rocommunity public" >> /etc/snmp/snmpd.conf [root@iZbp1f0r7cq40w7pws3kfpZ ~]# vim /etc/snmp/snmpd.conf [root@iZbp1f0r7cq40w7pws3kfpZ ~]# systemctl restart snmpd.service [root@iZbp1f0r7cq40w7pws3kfpZ ~]# systemctl status snmpd.service ● snmpd.service - Simple Network Management Protocol (SNMP) Daemon.
