Index of Development Pages and Resources

Servers

  • soylent-www - Primary Apache and slash server for main site.
  • soylent-db -- mysql server, holds the slash database
  • slashcott - Holds the slashcott site, development machine
  • soylent-services - mail, wiki, other services as needed

Known Problems

  • Need cron job to backup server
  • No init script for Apache.
  • Broken https configuration
    • Mostly fixed, Slash is the problem child now
  • Gluster is occassionally misfiring, manifests as Apache or slashd crashing depending on the node, can be fixed with the following command cocktail
sudo umount -l /srv/soylentnews.org # tells linux to lazy unmount, required when glusterd took a dive
sudo service glusterfs-server restart
sudo mount -a # will remount gluster without an issue

Then restart Apache/Slashd as required

Work Notes

DNS is completely run and managed by Linode's DNS Manager service. This was an expedient decision when trying to get off bluehost. We may want to investigate putting the master zone file on helium or boron and having external services handle serving out our dns.
