step

• Created in the time synchronization master node ntp.conffile
• Create a synchronization time from the node ntp.conffile
• Modify all nodes in the time zone
• Restart the primary node ntpdservice
• All the time synchronization slave nodes and the master node time
• Detecting whether time synchronization
• Restart from the node ntpdservice

Ntp.conf file is created in the time synchronization master node

Select a piece of equipment when time synchronization master node, run the following command, preparation of documents ntp.conf

sudo vim /etc/ntp.conf

Write the following:

driftfile /var/lib/ntp/drift

restrict default nomodify notrap nopeer noquery

restrict 127.0.0.1 
restrict ::1

# restrict 网段 mask 子网掩码
restrict 192.168.1.0 mask 255.255.255.0    # 修改这行     

server 127.127.1.0

includefile /etc/ntp/crypto/pw

keys /etc/ntp/keys

disable monitor

Creating ntp.conf file synchronization from the node at a time

All devices except the master node, run the following command ,, preparation of documents ntp.conf

sudo vim /etc/ntp.conf

Write the following:

driftfile /var/lib/ntp/drift

restrict default nomodify notrap nopeer noquery

restrict 127.0.0.1 
restrict ::1
# server 从节点 IP 地址
server 192.168.1.152       # 根据从节点实际 IP 地址修改

includefile /etc/ntp/crypto/pw

keys /etc/ntp/keys

disable monitor

Modify all nodes in the time zone

In 每一个the node running the following command to time zone changes to all nodesAsia/Shanghai

timedatectl set-timezone Asia/Shanghai

Restart the primary node ntpd service

In the primary node, run the following command:

systemctl restart ntpd

All the time synchronization slave nodes and the master node time

Run the following commands from the node on each machine:

Wherein: 192.168.1.151 represents the IP address of the master node

ntpdate 192.168.1.151

Detecting whether time synchronization

Each device has detected the same time, run the following command:

$ date

Thu Apr 18 16:50:07 CST 2019

From the restart the ntpd service node

Each node in a run from the command:

systemctl restart ntpd

Ambari cluster time synchronization is successful
