我安装了 RedHat 7 服务器，但是无法启动 snmpd 服务，原因如下：
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
好吧，错误很明显，snmpd 服务找不到serverz1-oam主机名。因此，解决方案可能是将其添加到 hosts 文件中。但这并不正确，因为真正的主机名是“服务器11“。我检查了 /etc/snmp/snmpd.conf，但没有这样的配置可以更改。那么，我该如何指示 snmp 获取 server11 主机名的地址？
非常感谢卢卡斯

该死！明白了，它在这些配置文件上：
/etc/sysconfig/snmpd
/etc/sysconfig/snmptrapd
抱歉浪费了论坛空间！
