Installing MariaDB 10 on CentOS 7

I have always used the stock install of MariaDB that came with CentOS 7, but I noticed recently that it is still only on 5.5 (at the time of writing, 5.5.60).

I never had any issues with it, until I tried to upgrade my Liferay CMS system. Apparently there are definite changes that are not incorporated into the 5.5.

I wished to moved to 10.3, which is the latest stable branch, and I can apparently do that (as indicated on the mariadb website¹) by creating a MariaDB repository for DNF and then installing as usual.

Of course, first uninstall the 5.5 version.

Backup & Restore of Payara Server

How do I backup and restore my domain in Payara (or glassfish for that matter.)

$ ./asadmin backup-domain --backupDir ~/mmud_backups/payara_backups domain1

It ends up in ~/mmud_backups/payara_backups/domain1/domain1_2019_01_27_v00001.zip

$ ./asadmin restore-domain --filename ~/mmud_backups/payara_backups/domain1/domain1_2019_01_27_v00001.zip --backupdir ~/mmud_backups/payara_backups domain1
Restored the domain (domain1) to ~/payara5/glassfish/domains/domain1
Command restore-domain executed successfully.
