由于名称或服务未知，RedHat 7 snmpd服务失败

Question

安装了RedHat 7服务器，但由于以下原因，无法启动snmpd服务：

server11# systemctl status snmpd
 snmpd.service - Simple Network Management Protocol (SNMP) Daemon.
 Loaded: loaded (/usr/lib/systemd/system/snmpd.service; enabled; vendor preset: disabled)
 Active: failed (Result: exit-code) since Tue 2017-12-12 11:51:13 CET; 25min ago
 Process: 20736 ExecStart=/usr/sbin/snmpd $OPTIONS -f (code=exited, status=1/FAILURE)
 Main PID: 20736 (code=exited, status=1/FAILURE)

Dec 12 11:51:13 oitwi11 systemd[1]: Starting Simple Network Management Protocol (SNMP) Daemon....
Dec 12 11:51:13 oitwi11 snmpd[20736]: getaddrinfo: serverz1-oam Name or service not known
Dec 12 11:51:13 oitwi11 snmpd[20736]: getaddrinfo("serverz1-oam", NULL, ...): Name or service not known
Dec 12 11:51:13 oitwi11 snmpd[20736]: Error opening specified endpoint "serverz1-oam:161"
Dec 12 11:51:13 oitwi11 snmpd[20736]: Server Exiting with code 1

错误是清楚的，snmpd服务找不到serverz1-oam主机名。因此，解决方案可以将其添加到主机文件中。但这是不正确的，因为真正的主机名是"server11“。我检查了/etc/snmp/snmpd.conf，但是没有需要更改的配置。那么，我如何指示snmp将地址获取到server11主机名呢？

非常感谢卢卡斯

妈的！明白了，它位于以下配置文件上：

/etc/sysconfig/snmpd
/etc/sysconfig/snmptrapd

抱歉浪费论坛空间！
