MariaDB/MySQL : How to get version information



Tags : mariadbmysql version openssl

Putting this here for my own future reference. Recently I need to move some databases to a new MariaDB server and part of the migration process requires me to find out the MariaDB version and the OpenSSL version used by MariaDB.

Below are two ways to find out the MariaDB version from console(terminal).

The first method allows us to see the rest of the MariaDB components version.

$ mysql -u root -p

MariaDB [(none)]> SHOW VARIABLES LIKE '%version%';

 +---------------------------------+------------------------------------------+
 | Variable_name | Value |
 +---------------------------------+------------------------------------------+
 | innodb_version | 10.3.15 |
 | protocol_version | 10 |
 | slave_type_conversions | |
 | system_versioning_alter_history | ERROR |
 | system_versioning_asof | DEFAULT |
 | version | 10.3.15-MariaDB-1:10.3.15+maria~bionic |
 | version_comment | mariadb.org binary distribution |
 | version_compile_machine | x86_64 |
 | version_compile_os | debian-linux-gnu |
 | version_malloc_library | system |
 | version_source_revision | 07aef9f7eb936de2b277f8ae209a1fd72510c011 |
 | version_ssl_library | OpenSSL 1.1.1  11 Sep 2018 |
 | wsrep_patch_version | wsrep_25.24 |
 +---------------------------------+------------------------------------------+
 13 rows in set (0.001 sec)

If you only want to know the MariaDB version and not the rest of the, then use this method:

$mysql -V

mysql Ver 15.1 Distrib 10.3.15-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2
