Centos system server setting time is automatically synchronized!

Automatically synchronizing time on the CentOS system server is one of the key steps to ensure the normal operation of the system. The following are brief steps to set the automatic synchronization time of the CentOS system server:

1. Installing and configuring NTP service
   
   In CentOS systems, NTP (Network Time Protocol) is a common protocol used for time synchronization. Execute the following commands to install and configure the NTP service:

   sudo yum install ntp

2. Enable NTP service
   
   Execute the following command to enable and start the NTP service:

   sudo systemctl enable ntpd
   sudo systemctl start ntpd

3. Configure NTP server
   
   Open the NTP configuration file
   /etc/ntp.conf, and use a text editor to edit:

   sudo vi /etc/ntp.conf

   Find available NTP server addresses in the file and configure them according to your location and preferences. You can find it at

   The website finds an available NTP server address.

   For example, add the following line to the configuration file to use a globally available NTP server:

   server 0.pool.ntp.orgserver 1.pool.ntp.orgserver 2.pool.ntp.org

4. Restart the NTP service
   
   Execute the following command to restart the NTP service so that the configuration changes take effect:

   sudo systemctl restart ntpd

5. Verify time synchronization
   
   Use the following command to verify that time synchronization is working properly:

   ntpq -p

   You will see the NTP servers listed and their status. Make sure a number is displayed in the "Reach" column to indicate that the NTP server is reachable.

Through the above steps, you can set up automatic time synchronization on the CentOS system server. The NTP service will periodically communicate with the configured NTP server to ensure system time accuracy and synchronization.
