MariaDB ColumnStore software upgrade 1.1.6 GA to 1.2.2 GA

MariaDB ColumnStore software upgrade 1.1.6 GA to 1.2.2 GA

This upgrade also applies to 1.2.0 Alpha to 1.2.2 GA upgrades

Changes in 1.2.1 and later

Non-distributed is the default distribution mode in postConfigure

The default distribution mode has changed from 'distributed' to 'non-distributed'. During an upgrade, however, the default is to use the distribution mode used in the original installation. The options '-d' and '-n' can always be used to override the default.

Non-root user sudo setup

Root-level permissions are no longer required to install or upgrade ColumnStore for some types of installations. Installations requiring some level of sudo access, and the instructions, are listed here: https://mariadb.com/kb/en/library/preparing-for-columnstore-installation-121/#update-sudo-configuration-if-needed-by-root-user

Running the mysql_upgrade script

As part of the upgrade process to 1.2.2, the user is required to run the mysql_upgrade script on all of the following nodes.

• All User Modules on a system configured with separate User and Performance Modules
• All Performance Modules on a system configured with separate User and Performance Modules and Local Query Feature is enabled
• All Performance Modules on a system configured with combined User and Performance Modules

mysql_upgrade should be run once the upgrade has been completed.

This is an example of how it run on a root user install:

/usr/local/mariadb/columnstore/mysql/bin/mysql_upgrade --defaults-file=/usr/local/mariadb/columnstore/mysql/my.cnf --force

This is an example of how it run on a non-root user install, assuming ColumnStore is installed under the user's home directory:

$HOME/mariadb/columnstore/mysql/bin/mysql_upgrade --defaults-file=$HOME/mariadb/columnstore/mysql/my.cnf --force

Setup

In this section, we will refer to the directory ColumnStore is installed in as <CSROOT>. If you installed the RPM or DEB package, then your <CSROOT> will be /usr/local. If you installed it from the tarball, <CSROOT> will be where you unpacked it.

Columnstore.xml / my.cnf

Configuration changes made manually are not automatically carried forward during the upgrade. These modifications will need to be made again manually after the upgrade is complete.

After the upgrade process the configuration files will be saved at:

• <CSROOT>/mariadb/columnstore/etc/Columnstore.xml.rpmsave
• <CSROOT>/mariadb/columnstore/mysql/my.cnf.rpmsave

MariaDB root user database password

If you have specified a root user database password (which is good practice), then you must configure a .my.cnf file with user credentials for the upgrade process to use. Create a .my.cnf file in the user home directory with 600 file permissions with the following content (updating PASSWORD as appropriate):

[mysqladmin]
user = root
password = PASSWORD

Choosing the type of upgrade

Note, softlinks may cause a problem during the upgrade if you use the RPM or DEB packages. If you have linked a directory above /usr/local/mariadb/columnstore, the softlinks will be deleted and the upgrade will fail. In that case you will need to upgrade using the binary tarball instead. If you have only linked the data directories (ie /usr/local/MariaDB/columnstore/data*), the RPM/DEB package upgrade will work.

Non-Root User Installs

Upgrade MariaDB ColumnStore from the binary tarball without sudo access (non-distributed mode)

This upgrade method applies when root/sudo access is not an option.

The uninstall script for 1.1.6 requires root access to perform some operations. These operations are the following:

• removing /etc/profile.d/columnstore{Alias,Env}.sh to remove aliases and environment variables from all users.
• running '<CSROOT>/mysql/columnstore/bin/syslogSetup.sh uninstall' to remove ColumnStore from the logging system
• removing the columnstore startup script
• remove /etc/ld.so.conf.d/columnstore.conf to ColumnStore directories from the ld library search path

Because you are upgrading ColumnStore and not uninstalling it, they are not necessary. If at some point you wish to uninstall it, you (or your sysadmin) will have to perform those operations by hand.

The upgrade instructions:

• Download the binary tarball to the current installation location on all nodes. See https://downloads.mariadb.com/ColumnStore/

• Shutdown the MariaDB ColumnStore system:

$ mcsadmin shutdownsystem y

• Copy Columnstore.xml to Columnstore.xml.rpmsave, and my.cnf to my.cnf.rpmsave

$ cp <CSROOT>/mariadb/columnstore/etc/Columnstore{.xml,.xml.rpmsave} 
$ cp <CSROOT>/mariadb/columnstore/mysql/my{.cnf,.cnf.rpmsave}

• On all nodes, untar the new files in the same location as the old ones

$ tar zxf columnstore-1.2.2-1.x86_64.bin.tar.gz

• On all nodes, run post-install, specifying where ColumnStore is installed

$ <CSROOT>/mariadb/columnstore/bin/post-install --installdir=<CSROOT>/mariadb/columnstore

• On all nodes except for PM1, start the columnstore service

$ <CSROOT>/mariadb/columnstore/bin/columnstore start

• On PM1 only, run postConfigure, specifying the upgrade, non-distributed installation mode, and the location of the installation

$ <CSROOT>/mariadb/columnstore/bin/postConfigure -u -n -i <CSROOT>/mariadb/columnstore

• Run the mysql_upgrade script on the nodes documented above for a non-root user install
