Installing and Configuring a Multi Server ColumnStore System - 1.1.X

Preparing to Install

After the MariaDB ColumnStore servers have been setup based on the Preparing for Installations document and the required MariaDB ColumnStore Packages have been Installed, use of the following option to configure and install MariaDB ColumnStore:

• MariaDB ColumnStore One Step Quick Installer Script - Release 1.1.6 and later
• MariaDB ColumnStore Post Install Script

NOTE: The install and setup had you install the packages on the node designed as Performance Module #1, 'pm1'. This is where the install script is run from, 'pm1'

If installing on a system where there is a need to multi servers initially planned in the future, you would be a multi server install instead of a single server install.

Going from one configuration to another will require a re-installation of the MariaDB ColumnStore software.

NOTE: You can install MariaDB ColumnStore as a root user or non-root user. This is based on how you setup the servers based on "Preparing for Installation Document". If installing as root, you need to be logged in as root user in a root login shell. If you are installing as non-root, you need to be logged in as a non-root user that was setup in the "Preparing for Installation Document".

MariaDB ColumnStore Post Install Script, postConfigure

The following is a transcript of a typical run of the MariaDB ColumnStore configuration script. Plain-text formatting indicates output from the script and bold text indicates responses to questions. After each question there is a short discussion of what the question is asking and what some typical answers might be. You will not see these discussions the running the actual configuration script.

Common Installation Examples

During postConfigure, there are 2 questions that are asked where the answer given determines the path that postConfigure takes in configuring the system. Those 2 questions are as follows:

Select the type of server install [1=single, 2=multi] (2) >

and

Select the Type of Module Install being performed:
1. Separate - User and Performance functionalities on separate servers
2. Combined - User and Performance functionalities on the same server
Enter Server Type ID [1-2] (1) >

The following examples illustrates some common configurations and helps to provide answers to the above questions:

• Single Node - User and Performance running on 1 server - single / combined
• Mutli-Node #1 - User and Performance running on some server - multi / combined
• Mutli-Node #2 - User and Performance running on separate servers - multi / separate

Post Configuration tool

Post Configuration tool, postConfigure, does the system configuration and setup. The servers and storages are configured during this process. It is executed from the designed 'pm1' node.

postConfigure script

To get additional information, user to run the following:

# /usr/local/mariadb/columnstore/bin/postConfigure -h

This is the MariaDB ColumnStore System Configuration and Installation tool.
It will Configure the MariaDB ColumnStore System based on Operator inputs and
will perform a Package Installation of all of the Modules within the
System that is being configured.

IMPORTANT: This tool should only be run on a Performance Module Server,
           preferably Module #1

Instructions:

	Press 'enter' to accept a value in (), if available or
	Enter one of the options within [], if available, or
	Enter a new value


Usage: postConfigure [-h][-c][-u][-p][-s][-port][-i][-n]
   -h  Help
   -c  Config File to use to extract configuration data, default is Columnstore.xml.rpmsave
   -u  Upgrade, Install using the Config File from -c, default to Columnstore.xml.rpmsave
	    If ssh-keys aren't setup, you should provide passwords as command line arguments
   -p  Unix Password, used with no-prompting option
   -s  Single Threaded Remote Install
   -port MariaDB ColumnStore Port Address
   -i Non-root Install directory, Only use for non-root installs
   -n Non-distributed install, meaning it will not install the remote nodes

postConfigure Install options

The postConfigure script supports 2 different types of installs:

• Distributed Install
• Non-Distributed Install

Distributed Install

Distributed Install by postConfigure will interact with all the nodes in the system during the configuration and setup process. It will push copied of the MariaDB ColumnStore packages from the 'pm1' node where postConfigure is running. During upgrades, it will also make sure the ColumnStore is stopped and will replace any packages that were previously install with the new package. Since it pushed the new packages to the other nodes, it is required that the packages be placed in the current home directory of the user doing the install, i.e. /root/ for root user install.

Distributed Install is the default setting, so no additional command line arguments need to be provide.

Non-Distributed Install

Non-Distributed Install by postConfigure will not have any interaction excluding a ping test during the configuration section to validate the IP address provided. With this option, it is up to the user to install the MariaDB ColumnStore packages on the non-pm1 nodes and startup the ColumnStore service before running postConfigure.

Non-Distributed Install does require an additional command line argument to be provided. The "-n" is the required argument as sown in this example:

/usr/local/mariadb/columnstore/bin/postConfigure -n

Running postConfigure

Running postConfigure is a bit different when launching as root user or a non-root user. As a non-root user, you will be required the setup 2 Environment variables and provide the base directory where MariaDB ColumnStore resides.

Running postConfigure as root user

/usr/local/mariadb/columnstore/bin/postConfigure

Running postConfigure as non-root user

export COLUMNSTORE_INSTALL_DIR=/home/guest/mariadb/columnstore
export LD_LIBRARY_PATH=/home/guest/mariadb/columnstore/lib:/home/guest/mariadb/columnstore/mysql/lib/mysql
/home/guest/mariadb/columnstore/bin/postConfigure -i /home/guest/mariadb/columnstore

postConfigure examples

Distributed Install example

This is an example of a Distributed Install of a 1UM/2PM system with internal storage. MariaDB ColumnStore 'rpm's packages was installed for this example. No password is provide on the command line, so the root user password is provided when prompted.

# /usr/local/mariadb/columnstore/bin/postConfigure

This is the MariaDB ColumnStore System Configuration and Installation tool.
It will Configure the MariaDB ColumnStore System and will perform a Package
Installation of all of the Servers within the System that is being configured.

IMPORTANT: This tool should only be run on the Parent OAM Module
           which is a Performance Module, preferred Module #1

              to stay single-server.

  'multi'   - Multi-Server install is used when you want to configure multiple servers now or
              in the future. With Multi-Server install, you can still configure just 1 server
              now and add on addition servers/modules in the future.

Data Replication Install example

This is an example of a Distributed Install of a 1UM/2PM system with Data Replication storage. Root user password is passed in as a command line argument.

As part of the Preparing for Install, the GlusterFS third party package would have already been installed on all of the PM servers within this system. During the running of postConfigure, the user will be required to enter some Data Replication options based on the type of system you want. Example is number of copies of the Database you would like to have maintained across the PM servers.

This example also enabled the Local Query Feature.

/usr/local/mariadb/columnstore/bin/postConfigure -p 'root-user-password'

This is the MariaDB ColumnStore System Configuration and Installation tool.
It will Configure the MariaDB ColumnStore System and will perform a Package
Installation of all of the Servers within the System that is being configured.

IMPORTANT: This tool should only be run on the Parent OAM Module
           which is a Performance Module, preferred Module #1

Prompting instructions:

	Press 'enter' to accept a value in (), if available or
	Enter one of the options within [], if available, or
	Enter a new value


===== Setup System Server Type Configuration =====

There are 2 options when configuring the System Server Type: single and multi

  'single'  - Single-Server install is used when there will only be 1 server configured
              on the system. It can also be used for production systems, if the plan is
              to stay single-server.

  'multi'   - Multi-Server install is used when you want to configure multiple servers now or
              in the future. With Multi-Server install, you can still configure just 1 server
              now and add on addition servers/modules in the future.

Select the type of System Server install [1=single, 2=multi] (2) > 


===== Setup System Module Type Configuration =====

There are 2 options when configuring the System Module Type: separate and combined

  'separate' - User and Performance functionality on separate servers.

  'combined' - User and Performance functionality on the same server

Select the type of System Module Install [1=separate, 2=combined] (2) > 1

Seperate Server Installation will be performed.

NOTE: Local Query Feature allows the ability to query data from a single Performance
      Module. Check MariaDB ColumnStore Admin Guide for additional information.

MariaDB Columnstore Memory Configuration

During the installation process, postConfigure will set the 2 main Memory configuration settings based on the size of memory detected on the local node.

The 2 settings are in the MariaDB Columnstore Configuration file, /usr/local/mariadb/columnstore/etc Columnstore.xml. These 2 settings are:

'NumBlocksPct'   - Performance Module Data cache memory setting

TotalUmMemory  - User Module memory setting, used as temporary memory for joins

On a system that has the Performance Module and User Module functionality combined on the same server, this is the default settings:

NumBlocksPct    - 50% of total memory

TotalUmMemory - 25% of total memory, default maximum the percentage equal to 16G

On a system that has the Performance Module and User Module functionality on different servers, this is the default settings:

NumBlocksPct    - This setting is NOT configured, and the default that the applications will then use is 70%

TotalUmMemory - 50% of total memory 

The user can choose to change these settings after the install is completed, if for instance they want to setup more memory for Joins to utilize. On a single server or combined UM/PM server, it is recommended to not have the combination of these 2 settings over 75% of total memory
