CDH报错： 主机的 NTP 服务未同步至任何远程服务器

主机的 NTP 服务未同步至任何远程服务器。

可以采取以下方式解决

选择ntp时间服务器 : 10.0.61.4

Step1 : 进入linux ntpd 配置目录,并修改配置文件如下:

vim /etc/ntp.conf

# 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).

 

driftfile /var/lib/ntp/drift

 

# Permit time synchronization with our time source, but do not

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

restrict default kod nomodify notrap nopeer noquery

restrict -6 default kod nomodify notrap nopeer noquery

 

# Permit all access over the loopback interface.  This could

# be tightened as well, but to do so would effect some of

# the administrative functions.

restrict 127.0.0.1

restrict -6 ::1

 

# Hosts on local network are less restricted.

#restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap

 

# Use public servers from the pool.ntp.org project.

# Please consider joining the pool (http://www.pool.ntp.org/join.html).

#server 0.centos.pool.ntp.org iburst

#server 1.centos.pool.ntp.org iburst

#server 2.centos.pool.ntp.org iburst

#server 3.centos.pool.ntp.org iburst

 

server 10.0.61.4 prefer

server 127.127.1.0

fudge 127.127.1.0 stratum 10

 

#fudge 127.127.1.0 stratum 2

#restrict 10.0.61.4 mask 255.255.255.255

 

 

#broadcast 192.168.1.255 autokey         # broadcast server

#broadcastclient                       # broadcast client

#broadcast 224.0.1.1 autokey                  # multicast server

# Enable public key cryptography.

# with symmetric key cryptography.

# Specify the key identifiers which are trusted.

# Specify the key identifier to use with the ntpdc utility.

#requestkey 8

 

# Specify the key identifier to use with the ntpq utility.

vim /etc/ntp/step-tickers

10.0.61.4

 

Step2:重启ntpd服务

service ntpd restart

step3:检查ntpd服务

ntpdc -np

打印如下信息,说明配置成功

配置的时候注意：权限问题

另一种方法吗：如果可以的话。整个集群重启也是可以的
