The production mail server is a Debian 10 LXD container administered by [[SAC]], hosted on [[osgeo9]].
  
The host is reachable by ssh at osgeo6.osgeo.osuosl.org. Anyone in the https://www.osgeo.org/cgi-bin/auth/ldap_shell.py has ssh access, and anyone in this group can add new people via the link. Sudo access can be provided by existing sudoer's by adding folks to the sudoers group in /etc/group, though it is normal practice to try and only extend sudo access to one user per project.

This hardware hosts several '''critical resources''', projects web sites mail-transport and -lists, it is the successor of the [[ProjectsVM]] amd the [[MailVM]], put into service in 2015. It is a shared environment and it is important that folks making changes on the system be aware of the impact they might have on other hosted services. Apache changes should be made carefully and needfully. Think about '''security'''!

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
    • certbot-auto lives in /usr/local/sbin.
    • 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

Backup strategy

See SAC:Backups for general info about backup strategies for containers.

A dump of each mysql database is also stored as a separate file under /osgeo (created during the backup phase).
