Troubleshooting Linux Server Ntpdate sync time error The NTP socket is in use, exiting

Source: Internet

error message:

Error reason analysis:

Because the XNTPD is already bound to the Socket. When you run Ntpdate, it broadcasts first, and then listens on port 123.

If XNTPD is running and a process is already listening on that port, it will cause ntpdate to fail to run on it. Run the following command to find the PID of the XNTPD

Solution:

Appears: pts/0 00:00:00 grep xntpd indicates that no PID was found.
Using lsof–i:123

Output:

-bash:lsof:command not found

Description not installed Lsof

Execute command:

The following message appears to indicate that the installation was successful

Execute command:

Lsof-i:123

Kill-9 1324
Clear (Kill) the process, and then try to synchronize with the NTP server again
Ntpdate ntp1.aliyun.com

The following screen shows that synchronization time is successful!
