* General information

Red Hat Software Collections contains the server part of MariaDB 10.1 database.
|
|
|
f55c7d |
The core Red Hat Enterprise Linux 6 provides version 5.1 of MySQL databases
|
|
|
f55c7d |
(client library and server daemon) and the core Red Hat Enterprise Linux 7
|
|
|
f55c7d |
provides version 5.5 of MariaDB databases (client library and server daemon) .
|
|
|
f55c7d |
|
|
|
f55c7d |
A protocol which is used between the client library and the daemon (MySQL
|
|
|
f55c7d |
and MariaDB are compatible enough from this POV) is stable across database
|
|
|
f55c7d |
versions, so using, for example, the MySQL 5.1 client library with the
|
|
|
f55c7d |
MariaDB 10.1 daemon works as expected.

* Usage of database connectors for dynamic languages
|
|
|
f55c7d |
|
|
|
f55c7d |
Client libraries from MySQL 5.1 or MariaDB 5.5 are used in database connectors
|
|
|
f55c7d |
for dynamic languages (Python, Perl, PHP, Ruby) and libraries that are part
|
|
|
f55c7d |
of the core Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7.
|
|
|
f55c7d |
|
|
|
f55c7d |
The same client libraries from MySQL 5.1 or MariaDB 5.5 are used in database
|
|
|
f55c7d |
connectors for more recent version of dynamic languages that are part of
|
|
|
f55c7d |
the Red Hat Software Collections.

* How to build applications for MariaDB 10.1 from Red Hat Software Collection
|
|
|
f55c7d |
|
|
|
f55c7d |
MariaDB 10.1 from Red Hat Software Collection does not include database
|
|
|
f55c7d |
connectors; client libraries packaged in the MariaDB 10.1 Red Hat Software
|
|
|
f55c7d |
Collections database packages are not supposed to be used as they are included
|
|
|
f55c7d |
only for purposes of server utilities and the daemon. Users are instead
|
|
|
f55c7d |
expected to use the system libraries and database connectors provided by
|
|
|
f55c7d |
MySQL 5.1 or MariaDB 5.5 with the core system.
|
|
|
f55c7d |
|
|
|
f55c7d |
It means that users who would like to link their application against MariaDB
|
|
|
f55c7d |
client library should compile and link it against MySQL 5.1 or MariaDB 5.5
|
|
|
f55c7d |
in the core Red Hat Enterprise Linux environment, not in MariaDB 10.1 Red Hat
|
|
|
f55c7d |
Software Collections environment.
|
|
|
f55c7d |
|
|
|
f55c7d |
The only exception to this are server-side plugins, which are expected
|
|
|
f55c7d |
to be built under MariaDB 10.1 Red Hat Software Collections environment,
|
|
|
f55c7d |
which means the build process should be run inside "scl enable rh-mysql101 '...'"
|
|
|
f55c7d |
call.
