After the MariaDB ColumnStore server 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:
This Article shows how to install on a single server system.
If installing a single combined functionality server with no plans to add additional servers, Single Node should be chosen.
Going from one configuration to another will require a re-installation of the MariaDB ColumnStore software.
The following is a transcript of a typical runs of the MariaDB ColumnStore configuration/install scripts. 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.
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 One Step Quick Installer Script, quick_installer_single_server.sh, is used to perform a simple 1 command run to perform the configuration and startup of MariaDB ColumnStore package on a Single Server setup. This will work with both root and non-root installs. Available in Release 1.1.6 and later.
It will perform an install with these defaults:
/usr/local/mariadb/columnstore/bin/quick_installer_single_server.sh --help Usage ./quick_installer_multi_server.sh Quick Installer for a Single Server MariaDB ColumnStore Install
# /usr/local/mariadb/columnstore/bin/quick_installer_single_server.sh
Run post-install script
The next step is:
If installing on a pm1 node:
/usr/local/mariadb/columnstore/bin/postConfigure
If installing on a non-pm1 using the non-distributed option:
/usr/local/mariadb/columnstore/bin/columnstore start
Run postConfigure script
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 requires to run on the Performance Module #1
With the no-Prompting Option being specified, you will be required to have the following:
1. Root user ssh keys setup between all nodes in the system or
use the password command line option.
2. A Configure File to use to retrieve configure data, default to Columnstore.xml.rpmsave
or use the '-c' option to point to a configuration file.
===== Quick Install Single-Server Configuration =====
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.

Run the script 'postConfigure' to complete the configuration and installation.
During postConfigure, this first question will be asked. Select 1 for a Single Server Install
Select the type of server install [1=single, 2=multi] (1) > 1

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
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) > 1
Performing a Single Server Install.
Enter System Name (columnstore-1) > mymcs1
Notes: You should give this system a name that will appear in various Admin utilities, SNMP messages, etc. The name can be composed of any number of printable characters and spaces.
There are 2 options when configuring the storage: internal and external
'internal' - This is specified when a local disk is used for the DBRoot storage.
High Availability Server Failover is not Supported in this mode
'external' - This is specified when the DBRoot directories are mounted.
High Availability Server Failover is Supported in this mode.
<<code>>
Select the type of Data Storage [1=internal, 2=external] (1) > **<Enter>**
Notes: Choosing internal and using softlinks to point to an externally mounted storage will allow you to use any format (i.e., ext2, ext3, etc.).
Enter the list (Nx,Ny,Nz) or range (Nx-Nz) of dbroot IDs assigned to module 'pm1' (1) > 1
Notes: The installer will set up the number of dbroot directories based on this answer.
NOTE: Setting 'NumBlocksPct' to 50%
Setting 'TotalUmMemory' to 25% of total memory (Combined Server Install maximum value is 16G).
Value set to 4G
Notes: The default maximum for a single server is 16Gb.

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 Single Server Install, this is the default settings:
NumBlocksPct - 50% of total memory TotalUmMemory - 25% of total memory, default maximum the percentage equal to 16G
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.
