This page details step 3 of a 5-step procedure for deploying Single-Node Enterprise ColumnStore with Local storage.
This step starts and configures MariaDB Enterprise Server and MariaDB Enterprise ColumnStore 23.10.
Interactive commands are detailed. Alternatively, the described operations can be performed using automation.
Mandatory system variables and options for Single-Node Enterprise ColumnStore include:
Start and enable the MariaDB Enterprise Server service, so that it starts automatically upon reboot:
Start and enable the MariaDB Enterprise ColumnStore service, so that it starts automatically upon reboot:
Enterprise ColumnStore requires a mandatory utility user account. By default, it connects to the server using the root user with no password. MariaDB Enterprise Server 10.6 will reject this login attempt by default, so you will need to configure Enterprise ColumnStore to use a different user account and password and create this user account on Enterprise Server.
On the Enterprise ColumnStore node, create the user account with the statement:
On the Enterprise ColumnStore node, grant the user account SELECT privileges on all databases with the GRANT statement:
Configure Enterprise ColumnStore to use the utility user:
Set the password:
For details about how to encrypt the password, see "".
Passwords should meet your organization's password policies. If your MariaDB Enterprise Server instance has a password validation plugin installed, then the password should also meet the configured requirements.
The specific steps to configure the security module depend on the operating system.
Configure SELinux for Enterprise ColumnStore:
To configure SELinux, you have to install the packages required for audit2allow. On CentOS 7 and RHEL 7, install the following:
On RHEL 8, install the following:
Allow the system to run under load for a while to generate SELinux audit events.
After the system has taken some load, generate an SELinux policy from the audit events using audit2allow:
If no audit events were found, this will print the following:
If audit events were found, the new SELinux policy can be loaded using semodule:
Set SELinux to enforcing mode by setting SELINUX=enforcing in /etc/selinux/config.
For example, the file will usually look like this after the change:
Set SELinux to enforcing mode:
