Synchronizing cluster server clocks to Network Time Protocol

It is important to ensure that the clocks of all cluster servers are synchronized.

When you initially install RP the install script asks you for permissions to configure a scheduled Cron job, which ensures that the server clock is always synchronized.

If you did not confirm configuring this job during the installation process, use the Network Time Protocol (NTP) regularly to ensure that all server clocks are synchronized.

To synchronize the server clock, run the command relevant to your specific operating system. For example, in Ubuntu, the following command can be used to synchronize a server’s clock to an NTP server:
/etc/network/if-up.d/ntpdate

It is advisable to configure a scheduled Cron job that executes this command daily on all servers, if you did not confirm the automatic execution when prompted to do so by the install script.
