1.安装JDK
下载安装jdk1.6以上版本,配置java环境变量
2.安装KETTLE:
官方下载地址:http://community.pentaho.com/projects/data-integration/
下载完后,解压到:E:\project\Kettle\data-integration即可
3.运行spoon
在不同的平台上运行spoon所支持的脚本:
Spoon.bat:在Windows平台上运行spoon;
Spoon.sh:在Linux、AppleOSX、Solaris平台上运行Spoon。
4. 配置JVM及内存配置问题
如果java_home设置了,仍提示: could not find the main class. Program will exit!
可以设置环境变量:
PENTAHO_JAVA_HOME,变量值为:jdk的安装目录,1.6以上即可,本机为: C:\Program Files (x86)\Java\jdk1.8.0_131;
KETTLE_HOME,变量值:E:\project\Kettle\data-integration
5. 如果启动还报错 ERROR:could not create the java virtual machine! 不是Java虚拟出了问题,修改一下spoon.bat里内存配置:
if "%PENTAHO_DI_JAVA_OPTIONS%"=="" set PENTAHO_DI_JAVA_OPTIONS="-Xms1024m" "-Xmx2048m" "-XX:MaxPermSize=256m"
改为:
if "%PENTAHO_DI_JAVA_OPTIONS%"=="" set PENTAHO_DI_JAVA_OPTIONS="-Xms512m" "-Xmx1024m" "-XX:MaxPermSize=256m"
6. 连接数据库找不到驱动问题(MySql为例)
提示错误[mysql] : org.pentaho.di.core.exception.KettleDatabaseException:
Error occured while trying to connect to the database
Driver class ‘org.gjt.mm.mysql.Driver‘ could not be found, make sure the ‘MySQL‘ driver (jar file) is installed.
org.gjt.mm.mysql.Driver
解决办法:把mysql-connector-java-5.1.42-bin.jar拷贝到E:\project\Kettle\data-integration\lib下面,然后重新启动spoon即可。
