Starting / Stopping DSpace (and related services)

The 'dspace' user can easily start/stop PostgreSQL and Tomcat using the corresponding service scripts:

Code Block
sudo service postgresql start
sudo service tomcat7 start

sudo service tomcat7 stop
sudo service postgresql stop

Important Cron Jobs

Obviously, you can get the latest information on the existing Cron jobs by logging into the server and running:

Code Block
crontab -l

However, here's a brief overview of a few of the more important Cron jobs.

Reset DSpace Content (based on AIPs) every Saturday

EVERY SATURDAY NIGHT (currently at 23:59 UTC), all existing DSpace content is automatically REMOVED and reset to the AIPs located at ~/AIP-restore/

This is controlled by the ~/bin/reset-dspace-content script (source code in GitHub)

This is a BASH script that essentially does the following:


Code Block
sudo apt-get install python-letsencrypt-apache
# register and request firtfirst certificate, but do not change Apache configuration (we'll do it manually)
sudo letsencrypt --apache certonly

Enter email address (used for urgent notices and lost key recovery)

Which names would you like to activate HTTPS for?

 - If you lose your account credentials, you can recover through
   e-mails sent to
 - Congratulations! Your certificate and chain have been saved at
   /etc/letsencrypt/live/ Your cert will
   expire on 2017-01-04. To obtain a new version of the certificate in
   the future, simply run Let's Encrypt again.
 - Your account credentials have been saved in your Let's Encrypt
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Let's
   Encrypt so making regular backups of this folder is ideal.
# replace self-signed certificates with Let's Encrypt certificates
sudo vim /etc/apache2/sites-enabled/
  ## SSL directives
  SSLEngine on
#  SSLCertificateFile      "/etc/ssl/certs/ssl-cert-snakeoil.pem"
#  SSLCertificateKeyFile   "/etc/ssl/private/ssl-cert-snakeoil.key"
#  SSLCACertificatePath    "/etc/ssl/certs"
  SSLCertificateFile    /etc/letsencrypt/live/
  SSLCertificateKeyFile /etc/letsencrypt/live/
  SSLCACertificateFile  /etc/letsencrypt/live/
# test renewal (dry run)
sudo letsencrypt renew --dry-run --agree-tos
# set up renewal from cron
sudo vim /etc/cron.d/certbot
# /etc/cron.d/certbot: crontab entries for the certbot package
# Upstream recommends attempting renewal twice a day
# Eventually, this will be an opportunity to validate certificates
# haven't been revoked, etc.  Renewal will only occur if expiration
# is within 30 days.
