  1. Web Server Migration April 30th, 2004 Presented by Geoff Strom Information Technology Services

  2. Topics • Reasons for Migration • User and Web Site Changes • Impact on Services • Hosting Structure • Directory Layout • System Administration • Schedule

  3. Reasons for Migration

  4. Concerns • WXA is unsupported at both the hardware and software level • Administration is minimal and done manually • Reliability and security are concerns

  5. Solutions • Future growth in web service offerings depends on an upgraded, secure, and manageable platform • Supported hardware is available (FXWEB1)

  6. User Changes

  7. Accounts • Will be named • Username same as SLU email • Initial quota will be 50MB • Will be verified nightly with system information • Accounts no longer in the system will be disabled immediately, pending removal

  8. Access • SFTP • SSH on request • No more insecure Telnet or FTP • Software upgrades will be necessary • Web based "control panel" containing account information and tools

  9. Web Site Changes

  10. Owner • Single defined owner • Will be able to assign group members • Web based "control panel" containing site information and tools • MySQL database server on request • PHP on request

  11. Groups • Named after the web site • Members have full read/write permissions • Only members will have access • Initial quota will be 100MB

  12. Impact on Services

  13. Services that will be migrated • All current web sites • phpMyAdmin (slumyadmin) • phpEasySurvey (EasySurvey) • Homefree (pages.slu.edu)

  14. Services that will not be migrated • ServletExec • TestPilot • UltimateBB

  15. By The Numbers • Approximately 300 user accounts will be migrated • Approximately 400 web sites will be migrated

  16. Hosting Structure Changes

  17. Current Hosting Structure • Three kinds of web sites • Domains • http://www.slucare.edu/ • Virtual Hosts • http://medschool.slu.edu/ • Everybody else • http://www.slu.edu/colleges/AS/ • http://www.slu.edu/centers/heartland/

  18. New Hosting Structure • Two kinds of web sites • Domains • http://www.slucare.edu/ • Virtual Hosts • http://medschool.slu.edu/ • All existing sites that are not already Domains or Virtual Hosts will be converted to Virtual Hosts

  19. Domains • Available via traditional addresses: • http://www.slucare.edu/

  20. Virtual Hosts • Available via traditional addresses: • http://medschool.slu.edu/ • Two alternative addresses will also be available: • http://www.medschool.slu.edu/ • http://www.slu.edu/medschool/

  21. Aliases • Redirects from the original address • http://www.slu.edu/colleges/medschool/ would redirect to http://medschool.slu.edu/ • Make transition easier but should expire • All converted web sites will be granted a temporary Alias to ease the transition

  22. Directory Layout

  23. Current Directory Layout

  24. New Directory Layout

  25. New Directory Layout • Home directories will have two sub directories: • files • public_html • Unable to modify home directory content • Access to web sites via symbolic links

  26. System Administration

  27. Current System Administration • Done manually • Small number of people with the skill and access to make changes

  28. New System Administration • Stored in a database • Easy to use front end • Increased number of administrators • Configuration files rebuilt automatically
