Solve the problem of non-synchronization of Debian time installed on the VM-Debian information of the Linux release technology. The following is a detailed description. Because the VM time is often not synchronized with the physical machine, it is best to use ntp in the VM to synchronize the time.
The Virtual Machine is installed with the Debian system, so apt is used for download and installation.
To the root user:
# Apt-cache search ntpdate
Because we do not need to set up an ntp server, we only need a client to synchronize the time. You can see that the software is ntpdate.
# Apt-get install ntpdate
Download and install it automatically.
After installation, use crontab to automatically update the time:
# Crontab-e
Add the following lines:
*/30 */usr/sbin/ntpdate time.cuit.edu.cn
This line means to automatically synchronize with the time server time.cuit.edu.cn every 30 minutes.
Save and exit.
