Overview
These instructions detail the upgrade from MariaDB Community Server to MariaDB Enterprise Server 10.5 on a range of supported Operating Systems.
When MariaDB Enterprise Server is upgraded, the old version needs to be uninstalled, and the new version needs to be installed.
Data Backup
Occasionally, issues can be encountered during upgrades. These issues can even potentially corrupt the database's data files, preventing you from easily reverting to the old installation. Therefore, it is generally best to perform a backup prior to upgrading. If an issue is encountered during the upgrade, you can use the backup to restore your MariaDB Server database to the old version. If the upgrade finishes without issue, then the backup can be deleted.
The instructions below show how to perform a backup using MariaDB Backup. For more information about backing up and restoring the database, please see the Recovery Guide.
Take a full backup.
On MariaDB Community Server 10.4 and later:
$ sudo mariadb-backup --backup \ --user=mariabackup_user \ --password=mariabackup_passwd \ --target-dir=/data/backup/preupgrade_backup
On MariaDB Community Server 10.3 and earlier:
$ sudo mariabackup --backup \ --user=mariabackup_user \ --password=mariabackup_passwd \ --target-dir=/data/backup/preupgrade_backup
Confirm successful completion of the backup operation.
The backup must be prepared.
On MariaDB Community Server 10.4 and later:
$ sudo mariadb-backup --prepare \ --target-dir=/data/backup/preupgrade_backup
On MariaDB Community Server 10.3 and earlier:
$ sudo mariabackup --prepare \ --target-dir=/data/backup/preupgrade_backup
Confirm successful completion of the prepare operation.
Backups should be tested before they are trusted.
Audit Plugin Considerations
If you have the MariaDB Audit Plugin installed and if you are upgrading to MariaDB Enterprise Server 10.4 or later, then the audit plugin should be removed prior to the upgrade to prevent conflict with the MariaDB Enterprise Audit Plugin that is present in MariaDB Enterprise Server 10.4 or later.
It can be removed by using the UNINSTALL SONAME statement:
UNINSTALL SONAME 'server_audit';
And if you load the plugin in a configuration file using the plugin_load_add
option, then the option should also be removed.
The MariaDB Enterprise Audit Plugin will automatically be installed after installing MariaDB Enterprise Server 10.4 or later.
Uninstall the Old Version
When upgrading to MariaDB Enterprise Server, it is necessary to remove the existing installation of MariaDB Community Server, before installing MariaDB Enterprise Server. Otherwise, the package manager will refuse to install MariaDB Enterprise Server.
Stop the MariaDB Server Process
Before the old version can be uninstalled, we first need to stop the current MariaDB Server process.
Set the innodb_
fast_ system variable toshutdown 1
:SET GLOBAL innodb_fast_shutdown = 1;
Use XA RECOVER to confirm that there are no external XA transactions in a prepared state:
XA RECOVER;
Commit or rollback any open XA transactions before stopping the node for upgrade.
Stop the server process:
For distributions that use systemd (most supported OSes), you can manage the Server process using the
systemctl
command:$ sudo systemctl stop mariadb
Uninstall via YUM (RHEL, CentOS, Rocky Linux)
Uninstall all of the MariaDB Community Server packages. Note that a wildcard character is used to ensure that all MariaDB Community Server packages are uninstalled:
$ sudo yum remove "MariaDB-*"
Be sure to check that this wildcard does not unintentionally refer to any of your custom applications:
Uninstall the Galera package as well.

Configuration
For platforms that use YUM or ZYpp as a package manager:
MariaDB Community Server's packages bundle several configuration files:
/etc/my.cnf
/etc/my.cnf.d/client.cnf
/etc/my.cnf.d/mysql-clients.cnf
/etc/my.cnf.d/server.cnf
If your version of any of these configuration files contained any custom edits, then the package manager may save your edited version with the .rpmsave
extension during the upgrade process. If you want to continue using your version with the custom edits, then you may need to move it back. For example, to move server.cnf
back in place:
$ sudo mv /etc/my.cnf.d/server.cnf /etc/my.cnf.d/server.cnf.original
$ sudo mv /etc/my.cnf.d/server.cnf.rpmsave /etc/my.cnf.d/server.cnf
Starting the Server
MariaDB Enterprise Server includes configuration to start, stop, restart, enable/disable on boot, and check the status of the Server using the operating system default process management system.
For distributions that use systemd, you can manage the Server process using the systemctl
command:
Operation | Command |
Start |
|
Stop |
|
Restart |
|
Enable during startup |
|
Disable during startup |
|
Status |
|
Upgrading the Data Directory
MariaDB Enterprise Server ships with a utility that can be used to identify and correct compatibility issues in the new version. After you upgrade your Server and start the server process, run this utility to upgrade the data directory.
The utility is called mariadb-upgrade in MariaDB Enterprise Server 10.4 and later:
$ sudo mariadb-upgrade
And the utility is called mysql_
$ sudo mysql_upgrade
Testing
When MariaDB Enterprise Server is up and running on your system, you should test that it is working and there weren't any issues during startup.
Connect to the server using MariaDB Client using the
root@localhost
user account.MariaDB Client is called mariadb (ES10.4 and later) or mysql (ES10.3 and earlier):
$ sudo mariadb
Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 9 Server version: 10.5.26-MariaDB MariaDB Server Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. MariaDB [(none)]>
You can also verify the server version by checking the value of the version system variable with the SHOW GLOBAL STATUS statement:
SHOW GLOBAL VARIABLES LIKE 'version';
+---------------+-----------------+ | Variable_name | Value | +---------------+-----------------+ | version | 10.5.26-MariaDB | +---------------+-----------------+
You can also verify the server version by calling the VERSION() function:
SELECT VERSION();
+-----------------+ | VERSION() | +-----------------+ | 10.5.26-MariaDB | +-----------------+
