Cornell University Library's CommonSpot installation is scaled to meet the needs of over 21 unit libraries that publish more than 70 web sites. This talk, given at a Commonspot Show and Tell, describes our system, based on Solaris and Oracle, that serves many virtual hosts while providing for separate test and production environments.

Commonspot installation at cornell university library

  1. 1. Commonspot Installation at Cornell University Library Paul Houle Library Systems Thanks: James Reidy, Surinder Ghangas, Ken Friedman, Chris Manly, David DeMello and Oya Reiger
  2. 2. Training Strategy Contributors Developers Designers Commonspot Oracle Apache Solaris HW The Big Picture CFMX
  3. 3. Context • Support 21 unit libraries and many projects • Current web server, copia, has • > 40 virtual hosts • > 170 toplevel directories • 500,000+ hits/day • Availability, Maintainability • Separate production and test • Isolate essential from inessential • Tight control
  4. 4. Hardware Sun Fire V440 Solaris 9 fibre channel StorEdge 6130 Array
  5. 5. Software • Solaris 9 • Oracle 9.2.0.6 • Cold Fusion MX 6.1 Enterprise Edition (Jrun 4) • 2x license for 4 CPU machine • install service pack 1 • upgrade Oracle drivers from Macromedia • Apache 2.0.54 • mod_cuwebauth • mod_jrun20 • CommonSpot 4.5sp1 • CornellCustomAuthZ
  6. 6. Two Instances SPOT SPOTTEST http port 80 http port X /spot/ apache /spottest/ apache spot jrun spottest jrun SPOT oracle SPOTTEST oracle
  7. 7. CFMX Installation • Multiple instances of Coldfusion: • Used J2EE installation mode w/ Jrun 4 (/opt/coldfusion/jrun4) • Install CFMX twice (/opt/coldfusion2/jrun4) • mv /opt/coldfusion2/jrun4/servers/cfusion -> /opt/coldfusion/jrun4/servers/spottest •JRUN Management console is nice, but.. • all servers must run as same UNIX user • no per-server jvm.config • /etc/init.d/{spot,spottest}-jrun • Use –config option to specify correct jvm.config
  8. 8. Namespace • Two to four letter code per site: • commonspot.library.cornell.edu -> cs • dlit.library.cornell.edu -> dl • insidecul.library.cornell.edu -> ins • Commonspot gets own root directory • can install other apps • good for migration: add redirects to new site • Avoids namespace collisions inside Cold Fusion • Short names can be used to compose Solaris usernames: • cs -> smb_cs
  9. 9. Apache Directory Layout /spot/ apache2/ bin/ conf/ httpd.conf vhosts.conf … commonspot/ commonspot-data/ sites/ commonspot.library.cornell.edu/ dlit.library.cornell.edu/
  10. 10. httpd.conf and vhost.conf httpd.conf: … Include conf/vhosts.conf vhosts.conf: … <VirtualHost commonspot.library.cornell.edu> Include/spot/sites/commonspot.library.cornell.edu/conf/host .conf </VirtualHost> …
  11. 11. Virtual host directory /spottest/sites/commonspot.library.cornell.edu/ conf/ host.conf designer/ … htdocs/ cs/ logs/ access_log error_log
  12. 12. host.conf ServerAdmin ph18@cornell.edu ServerName commonspot.library.cornell.edu DocumentRoot /spottest/sites/commonspot.library.cornell.edu/htdocs ErrorLog /spottest/sites/commonspot.library.cornell.edu/logs/error_l og CustomLog /spottest/sites/commonspot.library.cornell.edu/logs/access_ log combined RewriteEngine On RewriteRule ^/$ /cs/ [R]
  13. 13. Remote Access • Designers and programmers use SAMBA to access selected files in test instance. • Files belong to smb_{site name} • Symbolic links provide controlled view: • spot.library.cornell.edu{site_name} /spottest/sites/commonspot.library.cornell.edu/designer/ customcf -> ../htdocs/cs/customcf renderhandlers -> ../htdocs/cs/renderhandlers style -> ../htdocs/cs/style templates -> ../htdocs/cs/templates
  14. 14. Backups • System Backup • Weekly backup with mksysdb – keep 3 weeks back • Filesystem backup • ASDM incremental backup nightly – keep 3 version • Oracle Backup • incremental backup – every 8 hours • flush redo logs to archive • backup archive with ASDM • full backup – weekly, 5 am Saturday • shutdown oracle, take snapshot, restart oracle • mount snapshot, backup with ASDM -- Surinder Ghangas
  15. 15. CUWebAuth authentication • Developed by David Demello (ddd1@ cornell.edu) • Installation on server: • Install CornellCustomAuthZ in Commonspot Directory • Edit config.xml • (optional) put hooks in commonspot/newsite • Installation per site: • Hook files: login.cfm, after—login.cfm, custom-authentication.cfm, force-login.cfm • Edit config.xml • Key icon is glitchy, go to login.cfm instead - David DeMello
  16. 16. Creating a new site New Database, UNIX and SAMBA users Surinder Ghangas Create Directories and Virtual Host, configure CUWebAuth Paul Houle Create Site in Commonspot James Reidy
  17. 17. Copy Test to Production • User db must be synchronized • Export site db from Test Oracle • Create Production Site in Commonspot • Import site db into Production Oracle • Copy site directory • Check site ids in Application.cfm • Run migration tool
  18. 18. Gotchas • Oracle User Permissions (see sg14) • Be careful about installing at server root • WebDAV and ColdFusion don’t mix • Windows -> UNIX: Case sensitivity • Verity indexing of PDF files doesn’t work yet
  19. 19. Commonspot Software Configuration: James Reidy (jgr25@ cornell.edu) Apache, Jrun, CFMX, SAMBA: Paul Houle (ph18@ cornell.edu) Oracle, Backups, Unix admin: Surinder Ghangas (sg14@ cornell.edu) Authentication: David DeMello (ddd1@ cornell.edu) General Questions: Oya Rieger (oyr1@ cornell.edu) http://commonspot.library.cornell.edu/
