Changes and improvements to WebTech Linux web services

Following is an overview of upcoming changes and improvements to WebTech Linux web services, and a review of completed projects and service retirements. These include the cluster of services commonly referred to as "Webserve" (www.iu.edu, all campus gateway sites, and many departmental and organizational websites), and pages.iu.edu (individual) web pages.

This information will be updated regularly; dates are subject to change.

Changes to current services

PHP 5.6 retirement

PHP 5.6 will be retired in December 2018. This is a hard deadline due to the end of support for this version. Site owners should be aware of the following milestones:

  • January 18, 2018: The default version of PHP on test systems (webtest.iu.edu and webserve using iutestupgrade) was changed to 7.1.
  • March 22, 2018: PHP 7.1 will become the default version on production web servers. PHP 5.6 will still be available by specifying the PHP version in your .htaccess file.
  • December 17, 2018: PHP 5.6 will be retired on all Webserve and Webtest servers. All PHP applications will be directed to PHP 7.1.

CAS HTTPS requirement

Spring 2018: Applications which use CAS must use HTTPS. This change will only apply to CAS usage in application code (CAS logins using .htaccess on Webserve already require HTTPS).

File system migration (Webserve and Pages)

Summer 2018: The shared file system for webserve and pages.iu.edu will be retired in the fall of 2018, so user files must be migrated to a new file system. This will require no action on the part of site owners, and the way you access your files will not change. However, there may be a freeze on file changes during the migration. More details will be available at a later date.

Webserve/Transform/Siteshare retirement

Spring-Summer 2019: The current Webserve environment will be retired, along with Transform and Siteshare. See the description of the new server environment below.

New services

New web server and service management environment

Summer-Fall 2018: A new web server environment to replace the existing Webserve environment will be available. The two environments will exist side-by-side for several months to allow for a smooth transition. Details about migration procedures will be available at a later date.

Improvements and changes in the new environment will include:

  • Better performance and stability
  • PHP 7.1 only (or a later stable version), no PHP 5.6
  • HTTPS only: Any HTTP requests will be redirected to HTTPS
  • Full IPv6 support
  • No more ~username URLs; all sites will use virtual host names
  • Full duplication of resources between IUB and IUPUI data centers will provide robust disaster recovery
  • Self-service account and virtual host management
  • Automated server management will provide quicker, more flexible, and less disruptive system and software updates
