# Upgrading MariaDB MaxScale from 2.1 to 2.2
|
|
|
|
This document describes possible issues upgrading MariaDB MaxScale from version
|
|
2.1 to 2.2.
|
|
|
|
For more information about MariaDB MaxScale 2.2, please refer to the
|
|
[ChangeLog](../Changelog.md).
|
|
|
|
For a complete list of changes in MaxScale 2.2, refer to the
|
|
[MaxScale 2.2.1 Release Notes](../Release-Notes/MaxScale-2.2.1-Release-Notes.md).
|
|
[MaxScale 2.2.0 Release Notes](../Release-Notes/MaxScale-2.2.0-Release-Notes.md).
|
|
|
|
Before starting the upgrade, we recommend you back up your current configuration
|
|
file.
|
|
|
|
### Administrative Users
|
|
|
|
The file format for the administrative users used by MaxScale has been
|
|
changed. Old style files are automatically upgraded and a backup of the old file is
|
|
stored in `/var/lib/maxscale/passwd.backup`.
|
|
|
|
### Regular Expression Parameters
|
|
|
|
Modules may now use a built-in regular expression string parameter type instead
|
|
of a normal string when accepting patterns. The modules that use the new regex
|
|
parameter type are *qlafilter* and *tee*. When inputting pattern, enclose the
|
|
string in slashes, e.g. `match=/^select/` defines the pattern `^select`.
