Software Requirements

• Python (Already set up in /software)
• Ruby + Rubygems (Already set up in /software)
• Sandstorm Requirements
  • Swap to CLANG as the primary compiler
    • Clang compiler version 3.4 or better
  • Upgraded Kernel
    • Linux x86_64, with kernel version 3.13 or later
• Swap to Nginx?

Service Requirements

In decreasing order of priority:

1. Wordpress
2. GIT (and GitLab)
3. ShareLatex

Webserver

Apache is probably good enough, but many web-apps seem to only support Nginx. Would it be possible to install both so that we can start with Apache and then possibly transition over to Nginx at some point in the future?

Postgres

• Data Directory: /data/pgdata
• Start/Stop: init.d
• Test: psql should return DATABASE MISSING or ACCESS DENIED

GitLab relies on Postgres, as do several less critical services.

MySql

• Data Directory: system default
• Start/Stop: init.d
• Test: mysql should return ACCESS DENIED

Wordpress (the lab website) relies on Mysql. It would be nice if the data directory got moved to /data so that it got backed up properly.

MongoDB

• Data Directory: /data/mongodb
• Start/Stop: init.d
• Test: mongo should connect you to 'test'

MongoDB will be getting phased out in favor of using Sandstorm-based services, but it would be nice to have it available as a backup or during the transition phase to ensure that services that rely on it can be safely moved over.

Redis

• Data Directory: n/a (redis is not a persistent data store)
• Start/Stop: init.d
• Test: redis-cli should open up a shell.

Redis will be getting phased out in favor of using Sandstorm-based services, but it would be nice to have it available as a backup or during the transition phase to ensure that services rely on it can be safely moved over.

Wordpress

• Data Directory: [MySql] and /var/www/html/
• Start/Stop: Automatically served by Apache
• Test: http://odin.cse.buffalo.edu/
• Depends On: Apache, Mysql

Wordpress is mission critical.

ShareLaTeX

• Data Directory: /data/sharelatex
• User: sharelatex
• Start/Stop: Manual management using ~sharelatex/start_all.sh (super finicky setup...)
• Test: http://latex.odin.cse.buffalo.edu/
• Depends On: MongoDB, Redis

ShareLatex is not mission critical, and will be moving over to Sandstorm. However, it would be useful to have a useable install of ShareLaTeX during the transition period.

GitLab

• Data Directory: /data/git
• User: git
• Start/Stop: init.d
• Test: http://odin.cse.buffalo.edu/gitlab
• Depends On: MongoDB, Redis

GitLab is mission critical. It will be moving over to Sandstorm, but it is essential that GitLab be available in the interim.

GIT

• Data Directory: /data/git
• User: git
• Start/Stop: [Runs over SSHD]
• Test: git clone git@mjolnir.cse.buffalo.edu:odin-lab/documentation.git should say "Warning, cloned an empty repository"
• Depends On: GitLab

GIT runs over SSHD ~/.ssh/authorized_keys as an improvised ACL. This file is managed by GitLab, and uses a program called gitlab-shell to actually implement access control.
