kettle的安装很简单,到官网下载解压即可。只是启动时可能碰到一些问题,需要注意一下:
#需要编辑Spoon.bat,在其中找到该行,根据自己机器配置进行内存大小的调整 if "%PENTAHO_DI_JAVA_OPTIONS%"=="" set PENTAHO_DI_JAVA_OPTIONS="-Xms1024m" "-Xmx2048m" "-XX:MaxPermSize=256m"
创建数据库连接时,以mysql为例,如果连接测试时提示下面信息,说明缺少数据库连接的jar包,需要安装mysql的驱动jar包,下载地址:https://dev.mysql.com/downloads/connector/j/
错误连接数据库 [loan] : org.pentaho.di.core.exception.KettleDatabaseException:
Error occurred 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
下载后安装到\kettle8.3\data-integration\libswt\win64下面(64位机器),重启Spoon。

-- 允许root使用密码从任何主机连接到MySQL服务器 mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘123‘ WITH GRENT OPTION; -- 允许root使用密码从IP为172.16.16.120的主机远程连接到MySQL服务器的loan库 mysql> GRANT ALL PRIVILEGES ON loan.* TO ‘root‘@‘172.16.16.120‘ IDENTIFIED BY ‘123‘ WITH GRENT OPTION;
之后刷新权限使其生效
mysql> FLUSH PRIVILEGES;

如果错误信息中含有如上的提示,可以判断是MySQL时区的问题,可进行查看及配置。
show variables like ‘%time_zone%‘; set global time_zone=‘+8:00‘;
