* [[soylent-www]] - Primary Apache and slash server for main site.
List of servers on linode: [http://wiki.soylentnews.org/wiki/Category:SystemAdministration/Servers  Category:SystemAdministration/Servers]
* soylent-db -- mysql server, holds the slash database
* [[soylent-www]] - Primary Apache, mysqld, and varnish servers for main site. Fluorine hosts slashd and ipnd as well.
* slashcott - Holds the slashcott site, development machine
:: [[Hydrogen]], [[Fluorine]]
* [[soylent-services]] - mail, wiki, other services as needed
* soylent-db -- ndb-cluster servers for mysql, hold the rehash database.
 
:: [[Helium]], [[Neon]]
==Known Problems==
* dev -- Development server.
 
:: [[Lithium]]
* '''Need cron job to backup server'''
* staff-slash -- Staff server, ssh entry point, staff-only rehash.
* No init script for Apache.
:: [[Boron]]
* Broken https configuration
* irc -- IRC server and related services.
** Mostly fixed, Slash is the problem child now
:: [[Beryllium]]
* Gluster is occassionally misfiring, manifests as Apache or slashd crashing depending on the node, can be fixed with the following command cocktail
* [[SystemAdministration/Backups|backups]] -- Backup services. (NOT on linode)
<pre>
:: [[Oxygen]]
sudo umount -l /srv/soylentnews.org # tells linux to lazy unmount, required when glusterd took a dive
* directory services  -- Hesoid and Kerberos.
sudo service glusterfs-server restart
:: [[Helium]], [[Boron]]
sudo mount -a # will remount gluster without an issue
* [[soylent-services]] - mail, wiki, other services as needed.
 
:: [[Beryllium]]
Then restart Apache/Slashd as required
* [[load-balancer]]
</pre>
:: [[Sodium]], [[Magnesium]]
 
==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.
