Pentaho BI Suite Installation on Linux

Download pentaho-bi-suite-4.1.0-GA-i386.bin
create pentaho user and add it to sudo
sudo useradd -s /bin/bash -m pentaho 

login as pentaho user

chmod u+x  pentaho-bi-suite-4.1.0-GA-i386.bin

./pentaho-bi-suite-4.1.0-GA-i386.bin

In the wizard select custom option and select a path where you want pentaho to be installed and it will install all pre-reqs. I installed JDK, Tomcat and MySQL already. But it appears everything comes with the install and could be used unless you are on production.

sample users created are:
admin/welcome1(for http://localhost:8088)
joe/password (administrator)
suzy/password (system user)

mysql startup issues

In this note, I will document all startup issues that i had with mysql. Downloaded mysql community edition rpm 5.5.23 server and client packages and installed the using rpm -ivh <package names>

i tried to start using commands with mysqld but there were issues.

login as root and start mysql as below:

service mysql start

it worked.

Some other commands;
1. create user 'pbiuser'@'localhost' identified by 'welcome1';
2. create database 'bankdb';
3. create database bankdb;
4. grant usage on *.* to pbiuser identified by 'welcome1';
5. grant all privileges on bankdb.* to pbiuser@localhost;

Install 10.3.5 weblogic server as 11.1.1.6 requires this
Install base version 11.1.1.2 (install software - do not configure option)
