問題

There are OAuth errors and invalid timestamp warnings in the log, although the application links seem to be working correctly. In some cases, the JIRA issues macro will not display JIRA issues and the following will appear in the UI:

The following errors appear in the atlassian-confluence.log

原因

Servers do not have the correct system time, or are not updating with a network time server regularly. This can also happen after a server restart, if it has not synced to NTP yet. Validations between different servers (e.g. Confluence and JIRA) are also based on timestamps, and if the discrepancy is too big then they will not talk to each other.

回避策

  • Run the following commands on Linux:

    $ sudo apt-get install ntp (use 'yum install ntp' for CentOS or Redhat)
    $ sudo service ntp stop
    $ sudo ntpdate -s time.nist.gov (we can use any other server from here.
    $ sudo service ntp start

 

  • Run the following command on MacOS X:
    $ sudo ntpdate -u time.apple.com

     

  • Do the following on Windows:
    - Click on your date/time in the bottom right -> Change date and time settings... -> Update now
    - The default server is set to time.windows.com

ソリューション

For a more permanent fix, we want to make sure that our server is set up to sync with a network time server regularly. Here are a few different ways to do this in multiple Operating Systems.

Linux:
$ sudo service ntp stop

  • Edit your /etc/ntp.conf file to contain the servers you'd like to sync with (examples can be found here.
  • This is usually already configured. Sometimes when a server is restarted the system time might not sync. If that is the case then a manual one-time sync should resolve this.

$ sudo service ntp start
$ sudo ntpq -p

  • This will show you the delay, offset, and jitter for your ntp servers listed in the configuration file.


MacOS X:
$ sudo systemsetup -getnetworktimeserver
$ sudo ntpdate -u <time_server you want to use>


Windows:
Click on your date/time in the bottom right -> Change date and time settings...

  • Ensure 'Synchronize with Internet time server' is checked
  • Ensure you have a valid server selected 
  • Test your sync by clicking update now
