h2. Installing Sakai
* The following is the link to the official Sakai v2.1.0 installation guide:
** http://cvs.sakaiproject.org/release/2.1.0/InstallGuide.html
* Create a sakai user. Sakai user's home directory is at:
** /ucd/opt/sakai
* Make sure that you have the following packages installed: (Installed them in /ucd/pkg/ and create soft links to /ucd/opt/)
** ln -s /ucd/pkg/j2sdk1.4.2_10 /ucd/opt/java
** ln -s /ucd/pkg/jdk1.5.0_06 /ucd/opt/java5
** ln -s /ucd/pkg/maven-1.0.2 /ucd/opt/maven
** ln -a /ucd/pkg/apache-ant-1.6.5 /ucd/opt/ant
** Subversion client (You can also download the source code without having Subversion installed)
* Getting Tomcat (Installing tomcat in /ucd/pkg)
{noformat}
cd /ucd/pkg
wget http://apache.forbigweb.com/tomcat/tomcat-5/v5.5.12/bin/apache-tomcat-5.5.12.tar.gz
wget http://apache.forbigweb.com/tomcat/tomcat-5/v5.5.12/bin/apache-tomcat-5.5.12-compat.tar.gz
tar xvzf apache-tomcat-5.5.12.tar.gz
tar xvzf apache-tomcat-5.5.12-compat.tar.gz
ln -s /ucd/pkg/apache-tomcat-5.5.12 /ucd/opt/tomcat
{noformat}
* Setting environment variables
{noformat}
setenv ANT_HOME /ucd/opt/ant
setenv JAVA_HOME /ucd/opt/java
setenv MAVEN_HOME /ucd/opt/maven
setenv CATALINA_HOME /ucd/opt/tomcat
{noformat}
* Configure Tomcat
** Edit /ucd/opt/tomcat/conf/server.xml
{noformat}
Replace:
<Connector port="8080" maxHttpHeaderSize="8192"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" />
With:
<Connector port="8080" maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
debug="0" connectionTimeout="20000" disableUploadTimeout="true"
URIEncoding="UTF-8"/>
{noformat}
* Make sure that tomcat's ROOT webapp redirects to sakai
{noformat}
Create this file: /ucd/opt/tomcat/webapps/ROOT/index.html
With this content:
<html>
<head>
<meta http-equiv="refresh" content="0;url=/portal">
</head>
<body>
redirecting to /portal ...
</body>
</html>
{noformat}
* Setting up Maven
** Create repository directory:
{noformat}
install_repo.sh /ucd/opt/sakai/.maven/repository
Create /ucd/opt/sakai/build.properties file with the following content:
maven.repo.remote=http://www.ibiblio.org/maven/,http://cvs.sakaiproject.org/maven/,http://horde.planetmirror.com/pub/maven/
maven.tomcat.home=/ucd/opt/tomcat/
{noformat}
* Getting the latest source code (As per sakai-dev list, the recommendation is to run production code off the maintenance branch)
{noformat}
cd /ucd/opt/sakai
svn co https://source.sakaiproject.org/svn/branches/sakai_2-1-1 sakai-2-1-01-maint
{noformat}
* Building Sakai
{noformat}
cd /ucd/opt/sakai/sakai_2-1-01-maint
maven sakai
{noformat}
* Sakai configuration
{noformat}
Create a sakai folder
mkdir /ucd/opt/tocmat/sakai
Get a copy of the sakai.properties file and put it in the sakai folder
cp /ucd/opt/sakai/sakai_2-1-01-maint/docs/sakai.properties /ucd/opt/tomcat/sakai/
{noformat}
* Now configure the sakai.properties file
** e.g. Using Oracle and store content in file system

* Enable Kerberos Provider, for WebDav support
** Request a krb5.keytab file for the server you are running (service ticket), and also a krb5.conf file. You may do this by following these directions:
The page for requesting service principals:
https://computingaccounts.ucdavis.edu/cgi-bin/kerberos/index.cgi
Request {service/host}.ucdavis.edu with service as HTTP (in all caps).
For example, felix is set up as HTTP/felix.ucdavis.edu.
** Create a new file with the following contents. Name the file jaas.config.
{noformat}
KerberosAuthentication {
com.sun.security.auth.module.Krb5LoginModule required
debug=false
storekey=false
clearPass=false
useTicketCache=false
useKeyTab=true
keyTab="/etc/krb.keytab";
};
{noformat}
** Copy the above 3 files into your [jdk-src]/jre/lib/security/ directory. Note, in the jaas.config file you can identify where your keytab file resides if one wants to put it somewhere else. Also note the quotes around the file path.
** Enable the Kerberos Provider by first commenting out the SampleUserDirectoryProvider in the [sakai-src]/providers/src/component/src/webapp/WEB-INF/components.xml file. See below for the snippet to uncomment (REMEMBER TO COMMENT OUT THE SAMPLEUSERDIRECTORYPROVIDER!!!!):
{noformat}
<!-- below is orinally commented out, see KerberosDirectoryProvider documentation for further info -->

<property name="requireLocalAccount"><value>true</value></property>
<property name="knownUserMsg"><value>Integrity check on decrypted field failed</value></property>
</bean>
{noformat}
** Uncomment the KerberosProvider in the [sakai-src]/providers/component/project.xml file. See below:
{noformat}
<!-- Needed for the Kerberos Provider, is commented by default -->
<dependency>
<groupId>sakaiproject</groupId>
<artifactId>sakai-kerberos-provider</artifactId>
<version>${sakai.version}</version>
<properties>
<war.bundle>true</war.bundle>
</properties>
</dependency>
{noformat}
** Download current patch release of KerberosUserDirectoryProvider.java. Replace the "stock" kerberos provider with this one. The provider code is attached, and enables caching.
** Rebuild sakai for changes to take effect
* Enable logout functionality of Secureweb in Sakai
** Copy the contents of the following LoginTool.java code into the [saka-src/login/login/src/java/org/sakaiproject/tool/login directory. This file will replace the default code shipped with Sakai. Changes were made to the "complete" method to enable logout properly via DistAuth. Below is the entire code, or it may be found in SVN @
https://mware.ucdavis.edu/svn/sakai/distauth/trunk/LogoutSecureWebFunctionality/LoginTool.java
