The Sakai CLE is OS neutral. It is typically run on any of the numerous Linux distributions such as CentOS, Debian GNU/Linux, Fedora, Gentoo Linux, Red Hat Enterprise Linux (RHEL), SuSe Linux, Ubuntu but is also run on Mac OS X server, Microsoft Windows and Sun Solaris. Operating systems other than Linux are not nearly as well tested, and all of the community QA servers are running Linux, so this is generally the recommendation.

Oracle's Sun Java J2SE 5.0 (a.k.a Java 1.5) has completed the EOL process and is no longer supported. If are still running Java 1.5 please note that security vulnerabilities exist in JDK/JRE 5.0 updates 1.5.0_17 and earlier.
For Sakai 2.9 OpenJDK and JDK 7 are supported along with JDK 6. Previous releases would not work with OpenJDK.
Application server choices
The Sakai Community is overwhelmingly an Apache 2.2http/Apache Tomcat 5.5 user community and the Sakai CLE is at home in such an environment. Some Several schools run their Tomcats on with Windows IIS and nginx proxies without issue. Since Sakai CLE 2.7.0 a Websphere module was included in the release in order to facilitate deployment to a Websphere/Db2 production environment; however, support has waned and the Websphere option is currently considered deprecated. A few schools such as Hong Kong University of Science and Technology and the Universidad de Guadalajara report deploying Sakai on JBoss.It should be noted that currently Sakai CLE 2x is not compatible with Tomcat 6 or 7, a servlet container that some schools run as a standalone web server instead of fronting it with the Apache HTTP web server. It is anticipated that the Sakai CLE 2.9 release (Q2/Q3 2012) will be compatible with Tomcat 7.

| Sakai 2.8.0 and previous releases require Tomcat 5.5 out of the box but can be configured in custom builds to run under Tomcat 7. Tomcat 7 is the requirement for running Sakai 2.9.0+. There are some changes to the Tomcat configuration required to get Sakai to startup in the source or binary form under Tomcat 7. Please see this page for more information! |
Database choices
Sakai CLE production installations typically run either Oracle 10g/11g or MySQL 5.0/5.1. Support for IBM Db2 was added for the Sakai CLE 2.7.0 release but for 2.8.0 DB2 conversion scripts were not updated or tested and are currently considered deprecated. A demo version of Sakai includes HSQLDB; it should never be deployed in production.
