Final configuration and startup

Filesystem permissions

Set all the files to be owned by the gmn account, and to be writable by www-data:

$ sudo chown -R gmn:apache /var/local/dataone
$ sudo chmod -R g+w /var/local/dataone/

Initialize the database

sudo -Hu gmn bash -c '
  cd /var/local/dataone
  source gmn_venv_py3/bin/activate
  python /var/local/dataone/gmn_venv_py3/lib/python3.6/site-packages/d1_gmn/manage.py migrate --run-syncdb
'

Set server to UTC timezone (recommended)

GMN translates incoming date-times to UTC and provides outgoing date-times in UTC. Because of this, it is convenient to run the server in UTC, so that server related timestamps, such as the ones in logs, match up with timestamps stored in the GMN database and provided in DataONE REST API responses.

To check your time format:

$ date

The output should specify that that time given is in UTC, for example:

[mySudoerUser@centos7 dataone]$ date
  Thu Mar 23 20:27:52 UTC 2017

If not in UTC time, try:

$ rm -f /etc/localtime; ln -s /usr/share/zoneinfo/UTC /etc/localtime
$ echo 'ZONE="UTC"' > /etc/sysconfig/clock

Starting GMN

GMN should now be ready to start. Simply restart Apache:

$ sudo service httpd restart

Check the Apache logs for error messages. In case of any issues, refer to Troubleshooting
