The CNM Next Server (previously known as CNM Lab Server; hereinafter, the Server) is a compute server that is used for learning and testing. While being a part of CNM Servers, the Server utilizes one DigitalOcean droplet, which is located at the 134.209.40.232 IP address, and shall support all the applications installed at the Fellow Server and, in addition, one Humhub and one Tiki Wiki CMS Groupware instances.
Contents
Platform
The Server is set up as a Digitalocean droplet with dedicated 1 vCPU and 2GB / 50GB Disk in its NYC3 datacenter (New York). The dedicated resources can be increased when the existing ones can no longer support all the services that the Server is expected to provide.
OS
- Ubuntu 18.04.2 x64
DNS records
- All the Server's hostnames shall be fully qualified domain names (FQDNs). The following records shall be associated with the Server:
Record Hostname Value TTL (seconds) A next.friendsofcnm.org directs to 134.209.40.232 3600 A video.next.friendsofcnm.org directs to 134.209.40.232 3600 A lab.next.friendsofcnm.org directs to 134.209.40.232 3600 A cert.next.friendsofcnm.org directs to 134.209.40.232 3600 A wiki.next.friendsofcnm.org directs to 134.209.40.232 3600 A mail.next.friendsofcnm.org directs to 134.209.40.232 3600 A net.next.friendsofcnm.org directs to 134.209.40.232 3600 A linkup.next.friendsofcnm.org directs to 134.209.40.232 3600 CNAME www.next.friendsofcnm.org is an alias of next.friendsofcnm.org. 43200 NS friendsofcnm.org directs to ns1.digitalocean.com. 1800 NS friendsofcnm.org directs to ns2.digitalocean.com. 1800 NS friendsofcnm.org directs to ns3.digitalocean.com. 1800
- This list is way far from completion and needs to be further developed.
Applications
Certware
- One testing instance of CNM Certware shall be run on the Server and to be located at https://cert.next.friendsofcnm.org in the World Wide Web. The instance shall be based on Moodle software and shall duplicate the production instance located at https://cert.friendsofcnm.org
Labware
- One testing instance of CNM Labware shall be run on the Server and to be located at https://lab.next.friendsofcnm.org in the World Wide Web. The instance shall be based on a combination of Redmine and SVN software, linked to Bitbucket's file storage, and shall duplicate the production instance located at https://lab.friendsofcnm.org
Linkupware
- One testing instance of CNM Linkupware shall be run on the Server and to be located at https://linkup.next.friendsofcnm.org in the World Wide Web. The instance shall be based on SuiteCRM software and shall duplicate the production instance located at https://linkup.friendsofcnm.org
Mailware
- One testing instance of CNM Mailware shall be run on the Server and to be located at https://mail.next.friendsofcnm.org in the World Wide Web. The instance shall be based on Roundcube software and shall duplicate the production instance located at https://mail.friendsofcnm.org
Pageware
- One testing instance of CNM Pageware shall be run on the Server and to be located at https://page.next.friendsofcnm.org in the World Wide Web. The instance shall be based on WordPress software and shall duplicate the production instance located at https://page.friendsofcnm.org
Videoware
- One testing instance of CNM Videoware shall be run on the Server and to be located at https://video.next.friendsofcnm.org in the World Wide Web. The instance shall be based on YouPHPTube software and shall duplicate the production instance located at https://video.friendsofcnm.org
Wikiware
- Two testing instances of CNM Wikiware, for two different languages, shall be run on the Server and to be located at https://wiki.next.friendsofcnm.org in the World Wide Web. The instance shall be based on MediaWiki software and shall duplicate the production instance located at https://wiki.friendsofcnm.org . In addition, one instance of Tiki Wiki CMS Groupware shall be installed for testing purposes.
Server provisioning
Mail servers
- Postfix is the mail transfer agent which is responsible software for delivering and receiving emails.
Web servers
- Two web servers are designed to satisfy requests of World Wide Web clients. Nginx shall be placed in front of Apache HTTP Server. Nginx shall be used as a reverse proxy, load balancer, mail proxy and HTTP cache.
FTP servers
- A Very Secure File Transfer Protocol Daemon (vsFTPd) shall be used for secure file transfers.
Databases
- No standalone database server is planned. Separate database management systems, which are based on MariaDB instances, shall serve separate applications as follows:
Databases used in the Server CNM app DBMS Size (tables) Certware MariaDB Labware Linkupware Mailware Pageware Videoware Wikiware
- PostgreSQL and MongoDB may also be considered for further applications.
