how to install sakai source on windows

First of all, all the versions I use in this tutorial can install sakai 2.9.1, sakai 2.7, sakai 2.8 so you won't need to worry about if they work or not with three versions of sakai I list above.
This is my experiment when I install sakai a lot of times (can not count how many times I install Sakai and how many times I reinstall Window 7)

1. Install JDK 1.6:
• Run the set up file jdk-6u24-windows-i586.exe for window 32bit or jdk-6u37-windows-x64 for window 64bit.
• Install JDK into folder C:\opt\Java\jdk. Install JRE into the default folder when it asks (no need to change the default directory of JRE). 
• Setup the enviroment variables JAVA_HOME to point to the base directory of your JDK installation and also set JDK's /bin directory into PATH enviroment variable:
• Go to Control panel > System > Advanced system settings > Enviroment variables. Choose New in System variables. Then add:
• Variable name: JAVA_HOME
• Variable value: C:\opt\Java\jdk (the jdk directory we've just installed)
• Then find the PATH variables in System variables, EDIT > insert this line:
• ; C:\opt\Java\jdk\bin (becareful with the semicolon)
• To check it success or not. Go to cmd (window + R then type cmd > enter), type java -version > enter.
• If it's successfully:
java version "1.6.0_37"
Java(TM) SE Runtime Environment (build 1.6.0_37-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01, mixed mode)
• Notes: 
• Do not let the space in the directory of jdk installation
2. Install Maven 2.2.1:
• Download apache-maven-2.2.1-bin and extract it into C:\opt then rename as maven
• Set up the enviroment variables MAVEN_HOME
• Go to Control panel > System > Advanced system settings > Enviroment variables. Choose New in System variables. Then add:
• Variable name: MAVEN_HOME
• Variable value: C:\opt\maven (the jdk directory we've just installed)
• Then find the PATH variables in System variables, EDIT > insert in the end of PATH variable this line:
• ; C:\opt\maven\bin (becareful with the semicolon)
• Notes:
• Do not let the space in the directory of maven installation
• For example:
• Should: C:\opt\maven
• Should not: C:\im checker\maven, C:\Program File\maven
• To check it success or not: Go to cmd (window + R then type cmd > enter), type java -version > enter
• If it's successfully:
  Apache Maven 2.2.1 (r801777; 2009-08-07 02:16:01+0700)
  Java version: 1.6.0_37
  Java home: C:\opt\Java\jdk1.6.0_37\jre
  Default locale: en_US, platform encoding: Cp1252
  OS name: "windows 7" version: "6.1" arch: "amd64" Family: "windows"
• Continue setup the MAVEN_OPTS:
• Go to Control panel > System > Advanced system settings > Enviroment variables. Choose New in System variables. Then add:
• Variable name: MAVEN_OPTS
• Variable value: -Xms512m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=512m
• This variable value is very important, if something wrong, it will make Permgen space error. I will talk about this later.
• Create a local Maven reposity.
• Go to cmd (window + R then type cmd > enter), type:
• mkdir %HOMEDRIVE%%HOMEPATH%\.m2\repository -> enter
• This command will create a folder with directory:
  C:\Users\Your username\.m2\repository
• Copy setting.xml file in the below content into .m2 folder we just create above:
  
  <settings xmlns="http://maven.apache.org/POM/4.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
  http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <profiles>
  <profile>
  <id>tomcat5x</id>
  <activation>
  <activeByDefault>true</activeByDefault>
  </activation>
  <properties>
  <appserver.id>tomcat5x</appserver.id>
  <appserver.home>c:\opt\tomcat</appserver.home>
  <maven.tomcat.home>c:\opt\tomcat</maven.tomcat.home>
  <sakai.appserver.home>c:\opt\tomcat</sakai.appserver.home>
  <surefire.reportFormat>plain</surefire.reportFormat>
  <surefire.useFile>false</surefire.useFile>
  </properties>
  </profile>
  </profiles>
  </settings>
• The directory C:\opt\tomcat is the directory that we will install Tomcat 5.5.33 later.
3. Install Tomcat 5.5.33:


• Download apache-tomcat-5.5.33 (bin), extract it, copy to folder C:\opt > rename "tomcat"
• Set up the enviroment variables CATALINA_HOME
• Go to Control panel > System > Advanced system settings > Enviroment variables. Choose New in System variables. Then add:
• Variable name: CATALINA_HOME
• Variable value: C:\opt\tomcat (the tomcat root folder we've just installed)
• Then find the PATH variables in System variables, EDIT > insert in the end of PATH variable this line:
• ; C:\opt\tomcat\bin (becareful with the semicolon)
• Notes: 
• Do not let the space in the directory of tomcat installation
• For example:
• Should: C:\opt\tomcat\, C:\sakai\opt\tomcat\
• Should not: C:\im checker\tomcat, C:\Program File\tomcat
• Copy file setenv.bat with the below content into tomcat directory \bin (C:\opt\tomcat\bin):
  set JAVA_OPTS=-server -Xms512m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=512m -XX:NewSize=192m -XX:MaxNewSize=384m -Djava.awt.headless=true -Dhttp.agent=Sakai -Dorg.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING=false -Dsun.lang.ClassLoader.allowArraySyntax=true
• Notes:
• The JAVA_OPTS and MAVEN_OPTS above must have the same value that I mark it as red color.
• Copy MYSQL Java Connector file (*.jar) into Tomcat folder \common\bin (C:\opt\tomcat\common\lib) for install mysql later.
• Copy index.html file with the below content into tomcat folder \webapps\ROOT (C:\opt\tomcat\webapps\ROOT)
  <html>
  <head>
  <title>Redirecting to /portal</title>
  <meta http-equiv="Refresh" content="0:URL=/portal">
  </head>
  <body bgcolor="#ffffff" onLoad="javascript:window.location='/portal';">
  <div style="margin:18px;width:288px;background-color:#cccc99;padding:18px;border:thin solid #666600;text-align:justify">
  <p style="margin-top:0px">
  You are being redirected to the Sakai portal. If you are not automatically redirected, use the link below to continue:<br/>
  <a href="/portal">Take me to the Sakai portal</a>
  </p>
  </body>
  </html>
• Create sakai folder in tomcat root directory:
  C:\opt\tomcat\sakai
• Copy default.sakai.properties file from the below directory:
  

  
  sakai-src/config/configuration/bundles/src/bundle/org/sakaiproject/config/bundle/default.sakai.properties
  

• Copy that file into sakai folder you have just created (C:\opt\tomcat\sakai)
• Rename it: default.sakai.properties > sakai.properties
• You have to becareful with this file because if you install sakai with a lot version, such as sakai 2.9.1, sakai 2.8.0, sakai 2.7.0, you can make a mistake that you copy the same sakai.properties file from sakai version 2.7.0 into sakai version 2.8.0 > This will make your sakai install wrong version > failure. 
• Run service.bat file. Go to cmd (window + R then type cmd > enter), type:
  cd C:\opt\tomcat\binC:\opt\tomcat\bin> service.bat install
  
  
  
  
  C:\opt\tomcat\bin> tomcat5 //US//Tomcat5 ++JvmOptions -Xms512m; -Xmx1024m; -XX:PermSize=128m;-XX:MaxPermSize=512m;-Dfile.encoding=UTF-8; -Dorg.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING=false"
  C:\opt\tomcat\bin> tomcat5w //ES//Tomcat5
• When it appears a new window. In General tab, choose Automatic in the start type: Then click Start
  
• Change to the Java tab, insert 2 lines below at the end of Java options:
  -Dsun.lang.ClassLoader.allowArraySyntax=true
  -Dhttp.agent=Sakai
• Then clear the Initial memory pool and Maximum memory pool values.
  
• After all, click Apply.
4. Install Sakai source 2.8:
• Download sakai-src-2.8.0. Copy to folder C:\opt. Rename to "sakai"
• Deploy Sakai: 
• Go to cmd (window + R then type cmd > enter), type:
  cd C:\opt\sakai\master
  C:\opt\sakai\master mvn clean install
• You have to wait about 3 minutes. Then type,
  cd C:\opt\sakai
  C:\opt\sakai mvn clean install sakai:deploy -Dmaven.tomcat.home=C:\opt\tomcat
• Waiting about 2 or 3 hours depend on your network to finish the installation. (This is my result)
  
• After all, you just go to cmd: type, startup.bat to run tomcat.
• Go to your browser: http://localhost:8080/ to enjoy the result.
• If you want to close the sakai: go to cmd > shutdown.bat
• This version will work on HSQLDB. If you want to custom database, you have to install Sakai with MYSQL.
5. Install Mysql:
• In this tutorial, I install Sakai with Mysql (XAMPP version 6.7)
• Open file sakai.properties in folder C:\opt\tomcat\sakai (we created in number 3).
• Find and comment the below line in the HSQLDB setting part
• ## HSQLDB settings – on by default
• #vendor@org.sakaiproject.service.framework.sql.SqlService=hsqldb
• #driverClassName@javax.sql.BaseDataSource=org.hsqldb.jdbcDriver
• #hibernate.dialect=org.hibernate.dialect.HSQLDialect
• #validationQuery@javax.sql.BaseDataSource=select 1 from SYSTEM_USERS
• # two hsqldb storage options: first for in-memory (no persistence between runs), second for disk based
• #url@javax.sql.BaseDataSource=jdbc:hsqldb:
• #url@javax.sql.BaseDataSource=jdbc:hsqldb:${sakai.home}/db/sakai.db
• Find and edit this below line:
• Set username@javax.sql.BaseDataSource=sakaiuser
• Set password@javax.sql.BaseDataSource=sakaipassword
• sakaiuser is the username, sakaipassword is the password to access the database I will introduce to you later.
• Find and uncomment the below lines:
  ## MySQL settings – make sure to alter as appropriate
  vendor@org.sakaiproject.db.api.SqlService=mysql
  driverClassName@javax.sql.BaseDataSource=com.mysql.jdbc.Driver
  hibernate.dialect=org.hibernate.dialect.MySQLDialect
  url@javax.sql.BaseDataSource=jdbc:mysql://127.0.0.1:3306/sakai?
  useUnicode=true&amp;characterEncoding=UTF-8
  validationQuery@javax.sql.BaseDataSource=select 1 from DUAL
  defaultTransactionIsolationString@javax.sql.BaseDataSource=TRANSACTION_READ_COMMITTED
• Set up the enviroment variables MYSQL_HOME
• Go to Control panel > System > Advanced system settings > Enviroment variables. Choose New in System variables. Then add:
• Variable name: MYSQL_HOME
• Variable value: C:\xampp\mysql (folder mysql in XAMPP)
• Then find the PATH variables in System variables, EDIT > insert in the end of PATH variable this line:
• ; C:\xampp\mysql\bin (becareful with the semicolon)
• Go to your phpmyadmin, in my case is http://localhost/phpmyadmin/
• Go to SQL tab in your phpmyadmin and paste the below lines:
  create database sakai default character set utf8;
  grant all on sakai.* to sakaiuser@'localhost' identified by 'sakaipassword';
  grant all on sakai.* to sakaiuser@'127.0.0.1' identified by 'sakaipassword';
  flush privileges;
  
• sakaiuser and sakaipassword is the two values that I concern when we change the sakai.properties file.
• Finally, you have to go to cmd. Enter the command shutdown.bat then startup.bat again. Turn your browser on and enter http://localhost:8080/portal
• Enjoy your Sakai.
6. Hope this tutorial will help you install Sakai more easier.
