TODO: review/cleanup

  • backed up via bacula in BackupOg6 job (see /osgeo/backup)
  • admin user credentials found in ~root/.my.cnf

SSL certificates

  • LetsEncrypt is configured using certbot-auto
    • careful: check the conf files in /etc/apache2/sites-enabled/ to make sure that the VirtualHost settings do not include something like <VirtualHost _default_:443> and instead should point to the IP such as <VirtualHost 140.211.15.14:443> or else the certificate loaded will always default to mapserver.org

    • to add more sites, run the command:

      certbot-auto --apache -d mapserver.org -d www.mapserver.org

    • a cronjob (certbot-auto renew) was created to check for renewal twice a day
    • also enabled for geos.osgeo.org on by Jeff McKenna on 2018-10-01
