Upgrade MariaDB Upgrade path for MariaDB 10.1 to 10.3?

centmin.sh menu will only allow you to upgrade 1 major version at a time so to go from MariaDB 10.1 to 10.3, you need to do it in 2 steps

• step 1, 10.1 to 10.2
• step 2, 10.2 to 10.3

If you have a spare test VPS/server, you can manually enable the 10.1 to 10.2 upgrade routine in 123.09beta01 but any issues short term or long term wise you find would need to be reported to me but only resolution for that test VPS is to reinstall CentOS as I currently wouldn't have enough spare time to look into any issues with upgrade process (same with MariaDB 10.2 to 10.3 routine). So be prepared to backup data files and databases and wipe the server if MariaDB 10.2 test upgrade doesn't work.

On test VPS, you can enable Centmin Mod 123.09beta01's centmin.sh menu option 11 submenu option 6 to upgrade MariaDB 10.1.x branch to MariaDB 10.2.x branch by first setting in persistent config file at /etc/centminmod/custom_config.inc the variable BEFORE running centmin.sh

Code (Text):

ENABLE_MARIADBTENTWOUPGRADE='y'

There's also a variable ENABLE_MARIADBTENTHREEUPGRADE='y' to enable MariaDB 10.2.x to 10.3.x upgrades which is only supported on CentOS 7.x for now due to reported issues with CentOS 6. Again do on test VPS/server only and not live production server as MariaDB 10.2 to 10.3 has had even less long term testing than MariaDB 10.1 to 10.2 process. If you run into problems, my only solution for you is to setup a new VPS/server and reinstall Centmin Mod and migrate your site data and MySQL data if intact (if not that restore from MySQL backups).

 This script's MariaDB 10.2.x upgrade process is still in beta testing stages.
 So please test on a test server and not a live production server. But if you use
 on live server or if MySQL databases already exist, please back them up before
 running this upgrade script via mysqldump - instructions at:
 http://dev.mysql.com/doc/refman/5.6/en/mysqldump.html.

 ###          IMPORTANT MYSQLDUMP BACKUP BEFORE UPGRADE          ###
 ###        OR RISK DATA LOSS DUE TO MARIADB 10.2 Changes        ###
 ###################################################################

 For each DATABASENAME backup via mysqldump i.e.

  mysqldump --opt --routines DATABASENAME > /path/to/DATABASENAME_backup.sql

Have you backed up your databases ? [y/n] y

MariaDB 10.2.x https://mariadb.com/kb/en/mariadb/what-is-mariadb-102/

!!  Note  !!
upgrade process can take more >5 minutes.. you may want to shutdown
nginx server to not show mysql errors to visitors on your site or
put site(s) into maintenance mode before proceeding with mysql upgrade

Do you want to continue with upgrade to MariaDB 10.2.x ? [y/n] y

MariaDB 10.2.x Upgrade completed

Then future MariaDB 10.2.x branch updates are done via yum

Code (Text):

yum upgrade MariaDB-client MariaDB-common MariaDB-compat MariaDB-devel MariaDB-server MariaDB-shared

Upgrade MariaDB 10.1 To 10.2 & 10.2 To 10.3 Differences

MariaDB 10.1 to 10.2 has changes you need to be aware of which may affect your script/mysql using app specifically and Centmin Mod may not have tested for it so read Upgrading from MariaDB 10.1 to MariaDB 10.2 (centmin.sh menu option 11 takes care of step 1 to 8 with exception of step 4, you need to do MySQL backups yourself) and inspect /etc/my.cnf before and after MariaDB 10.2 upgrades. Centmin Mod upgrade routines try to as best adjust /etc/my.cnf for MariaDB 10.2 compatibility with previous MariaDB 10.1 but if your web app/scripts have issues, you'll need to figure those out yourself.

Same goes for MariaDB 10.2 to 10.3 upgrades Upgrading from MariaDB 10.2 to MariaDB 10.3 (centmin.sh menu option 11 takes care of step 1 to 8 with exception of step 4, you need to do MySQL backups yourself)

One of the big changes is from MariaDB 10.2.2 and newer, innodb_strict_mode is enabled by default while previously it was disabled by default and default options for sql_mode have changed.

• XtraDB/InnoDB Strict Mode
• MySQL :: MySQL 5.6 Reference Manual :: 14.14 InnoDB Startup Options and System Variables

Install MariaDB 10.3 By Default

Centmin Mod 123.09beta01 and newer now default to MariaDB 10.3 out of the box since enabling variable outlined at Beta Branch - allow MariaDB 10.3 MySQL to be default optionally

 

Private testing phase right now.

 

added official outline of options at MariaDB - MariaDB 10.1 upgrades to MariaDB 10.2, 10.3 and 10.4.
