已解决 NTP 没有找到适合同步的服务器 Centos

我正在尝试设置 ntp 服务器,但无法查询它。每次尝试时,我都会收到以下消息:

 6 Mar 18:57:01 ntpdate[27050]: no server suitable for synchronization found

这是我的 ntpd.conf 文件

# For more information about this file, see the man pages
# ntp.conf(5), ntp_acc(5), ntp_auth(5), ntp_clock(5), ntp_misc(5), ntp_mon(5).

# permit the source to query or modify the service on this system.

# Permit all access over the loopback interface.  This could
# be tightened as well, but to do so would effect some of
# the administrative functions.

检查 ntp 服务器的状态:systemctl status ntpd

如果已关闭:启动服务器:service ntpd start
