本文主要介绍pentaho8.1的安装过程，重点介绍pentaho-server的安装。
针对pentaho在线上使用必须使用mysql作为数据源，我们本次就以mysql作为数据源。

好，下面上货。
1、下载后有这些文件(能够直接解压缩执行，其中pentaho-server需要配置)
pentaho-server
pdi --pentaho data intergration
prd -- pentaho report desiginer
2、把pentaho-解压到/usr/local/petaho中
3、安装mysql（略）
4、修改pentaho的数据源到mysql，默认不是mysql的，需要修改。参考下面的文章（需要注意的是在创建表的时候尽量使用utf8）
https://help.pentaho.com/Documentation/8.1/Setup/Installation/Archive/MySQL_Repository
脚本位置（程序是通过压缩包解压后得到的）：
/usr/local/pentaho/pentaho-server/data/mysql5
需要注意的是创建三张表的时候需要把表的默认字符类型修改为utf8
5、注意需要修改文件pentaho-solutions/system/systemListener.xml(否则启动报错)
systemListener.xml
<!--<bean id="pooledDataSourceSystemListener" class="org.pentaho.platform.engine.services.connection.datasource.dbcp.PooledDatasourceSystemListener" />-->
<!--<bean id="nonPooledDataSourceSystemListener"
class="org.pentaho.platform.engine.services.connection.datasource.dbcp.NonPooledDatasourceSystemListener"/>-->
<!--<bean id="dynamicallyPooledDataSourceSystemListener" class="org.pentaho.platform.engine.services.connection.datasource.dbcp.DynamicallyPooledDatasourceSystemListener" />-->
6、使用命令启动
./start-pentaho.sh
7、查看tomcat/logs/pentaho.log是否有异常输出
例如输出如下：
