MariaDB has been updated to 10.4, MariaDB Galera to 26.4.
|
||
Before you upgrade, it would be best to take a backup of your database.
|
||
For MariaDB Galera Cluster, see <link xlink:href="https://mariadb.com/kb/en/upgrading-from-mariadb-103-to-mariadb-104-with-galera-cluster/">Upgrading
|
||
from MariaDB 10.3 to MariaDB 10.4 with Galera Cluster</link> instead.
|
||
Before doing the upgrade read <link xlink:href="https://mariadb.com/kb/en/upgrading-from-mariadb-103-to-mariadb-104/#incompatible-changes-between-103-and-104">Incompatible
|
||
Changes Between 10.3 and 10.4</link>.
|
||
After the upgrade you will need to run <literal>mysql_upgrade</literal>.
|
||
MariaDB 10.4 introduces a number of changes to the authentication process, intended to make things easier and more
|
||
intuitive. See <link xlink:href="https://mariadb.com/kb/en/authentication-from-mariadb-104/">Authentication from MariaDB 10.4</link>.
|
||
unix_socket auth plugin does not use a password, and uses the connecting user's UID instead. When a new MariaDB data directory is initialized, two MariaDB users are
|
||
created and can be used with new unix_socket auth plugin, as well as traditional mysql_native_password plugin: root@localhost and mysql@localhost. To actually use
|
||
the traditional mysql_native_password plugin method, one must run the following:
|
||
<programlisting>
|
||
services.mysql.initialScript = pkgs.writeText "mariadb-init.sql" ''
|
||
ALTER USER root@localhost IDENTIFIED VIA mysql_native_password USING PASSWORD("verysecret");
|
||
'';
|
||
</programlisting>
|
||
When MariaDB data directory is just upgraded (not initialized), the users are not created or modified.

MySQL server is now started with additional systemd sandbox/hardening options for better security. The PrivateTmp, ProtectHome, and ProtectSystem options
|
||
may be problematic when MySQL is attempting to read from or write to your filesystem anywhere outside of its own state directory, for example when
|
||
calling <literal>LOAD DATA INFILE or SELECT * INTO OUTFILE</literal>. In this scenario a variant of the following may be required:
|
||
- allow MySQL to read from /home and /tmp directories when using <literal>LOAD DATA INFILE</literal>
|
||
<programlisting>
|
||
systemd.services.mysql.serviceConfig.ProtectHome = lib.mkForce "read-only";
|
||
</programlisting>
|
||
- allow MySQL to write to custom folder <literal>/var/data</literal> when using <literal>SELECT * INTO OUTFILE</literal>, assuming the mysql user has write
|
||
access to <literal>/var/data</literal>
|
||
<programlisting>

systemd.services.mysql.serviceConfig.ReadWritePaths = [ "/var/data" ];

<para>
|
||
The MySQL service no longer runs its <literal>systemd</literal> service startup script as <literal>root</literal> anymore. A dedicated non <literal>root</literal>
|
||
super user account is required for operation. This means users with an existing MySQL or MariaDB database server are required to run the following SQL statements
|
||
as a super admin user before upgrading:
|
||
<programlisting>
|
||
CREATE USER IF NOT EXISTS 'mysql'@'localhost' identified with unix_socket;
|
||
GRANT ALL PRIVILEGES ON *.* TO 'mysql'@'localhost' WITH GRANT OPTION;
|
||
</programlisting>
|
||
If you use MySQL instead of MariaDB please replace <literal>unix_socket</literal> with <literal>auth_socket</literal>. If you have changed the value of <xref linkend="opt-services.mysql.user"/>
|
||
from the default of <literal>mysql</literal> to a different user please change <literal>'mysql'@'localhost'</literal> to the corresponding user instead.

like <command>whatis</command> and <command>apropos</command>. The caches are generated during the build of
|

the NixOS configuration: since this can be expensive when a large number of packages are installed, the

feature is disabled by default.

Zabbix now defaults to 5.0, updated from 4.4. Please carefully read through
|
||
<link xlink:href="https://www.zabbix.com/documentation/current/manual/installation/upgrade/sources">the upgrade guide</link>
|
||
and apply any changes required. Be sure to take special note of the section on
|

<link xlink:href="https://www.zabbix.com/documentation/current/manual/installation/upgrade_notes_500#enabling_extended_range_of_numeric_float_values">enabling extended range of numeric (float) values</link>

If you are using Zabbix Server with a MySQL or MariaDB database you should note that using a character set of <literal>utf8</literal> and a collate of <literal>utf8_bin</literal> has become mandatory with
|
||
this release. See the upstream <link xlink:href="https://support.zabbix.com/browse/ZBX-17357">issue</link> for further discussion. Before upgrading you should check the character set and collation used by
|
||
your database and ensure they are correct:
|
||
<programlisting>
|
||
SELECT
|
||
default_character_set_name,
|
||
default_collation_name
|
||
FROM
|
||
information_schema.schemata
|
||
WHERE
|
||
schema_name = 'zabbix';
|
||
</programlisting>
|
||
If these values are not correct you should take a backup of your database and convert the character set and collation as required. Here is an
|
||
<link xlink:href="https://www.zabbix.com/forum/zabbix-help/396573-reinstall-after-upgrade?p=396891#post396891">example</link> of how to do so, taken from
|
||
the Zabbix forums:
|
||
<programlisting>
|
||
ALTER DATABASE `zabbix` DEFAULT CHARACTER SET utf8 COLLATE utf8_bin;
|
||
|
||
-- the following will produce a list of SQL commands you should subsequently execute
|
||
SELECT CONCAT("ALTER TABLE ", TABLE_NAME," CONVERT TO CHARACTER SET utf8 COLLATE utf8_bin;") AS ExecuteTheString
|
||
FROM information_schema.`COLUMNS`
|

WHERE table_schema = "zabbix" AND COLLATION_NAME = "utf8_general_ci";

Cert generation now implicitly uses the <literal>acme</literal>

user, and the <literal>security.acme.certs._name_.user</literal> option

managed through group permissions. The module no longer runs lego

twice under certain conditions, and will correctly renew certificates if
|

their configuration is changed. Services which reload nginx and httpd after
|
||
certificate renewal are now properly configured too so you no longer have
|
||
to do this manually if you are using HTTPS enabled virtual hosts. A mechanism
|
||
for regenerating certs on demand has also been added and documented.

In addition to the hostname, the fully qualified domain name (FQDN),

which consists of <literal>${networking.hostName}</literal> and

The GNOME desktop manager no longer default installs <package>gnome3.epiphany</package>.

It was chosen to do this as it has a usability breaking issue (see issue <link xlink:href="https://github.com/NixOS/nixpkgs/issues/98819">#98819</link>)

that makes it unsuitable to be a default app.

The scripted networking system now uses <literal>.link</literal> files in

<literal>/etc/systemd/network</literal> to configure mac address and link MTU,

instead of the sometimes buggy <literal>network-link-*</literal> units, which

Bringing the interface up has been moved to the beginning of the

<literal>network-addresses-*</literal> unit.
|

Note this doesn't require <command>systemd-networkd</command> - it's udev that

parses <literal>.link</literal> files.

Extra care needs to be taken in the presence of <link xlink:href="https://wiki.debian.org/NetworkInterfaceNames#THE_.22PERSISTENT_NAMES.22_SCHEME">legacy udev rules</link>
|
||
to rename interfaces, as MAC Address and MTU defined in these options can only match on the original link name.
|
||
In such cases, you most likely want to create a <literal>10-*.link</literal> file through <xref linkend="opt-systemd.network.links"/> and set both name and MAC Address / MTU there.

any use case where this is not working well.

In particular, the <literal>RootDirectory</literal> option newly set
|

forbids uploading or downloading a torrent outside of the default directory
|
||
configured at <link linkend="opt-services.transmission.settings">settings.download-dir</link>.

If you really need Transmission to access other directories,
|

you must include those directories into the <literal>BindPaths</literal> of the service:

<programlisting>

systemd.services.transmission.serviceConfig.BindPaths = [ "/path/to/alternative/download-dir" ];

Use:
|

<programlisting>
|
||
services.transmission.settings.rpc-bind-address = "0.0.0.0";
|

</programlisting>
|
||
to get the previous behavior of listening on all network interfaces.

With this release <literal>systemd-networkd</literal> (when enabled through <xref linkend="opt-networking.useNetworkd"/>)

has it's netlink socket created through a <literal>systemd.socket</literal> unit. This gives us control over
|
||
socket buffer sizes and other parameters. For larger setups where networkd has to create a lot of (virtual)
|

devices the default buffer size (currently 128MB) is not enough.

|

On a machine with >100 virtual interfaces (e.g., wireguard tunnels, VLANs, …), that all have to

be brought up during system startup, the receive buffer size will spike for a brief period.

Eventually some of the message will be dropped since there is not enough (permitted) buffer
|

space available.

<para>
|
||
By having <literal>systemd-networkd</literal> start with a netlink socket created by
|
||
<literal>systemd</literal> we can configure the <literal>ReceiveBufferSize=</literal> parameter
|
||
in the socket options (i.e. <literal>systemd.sockets.systemd-networkd.socketOptions.ReceiveBufferSize</literal>)
|

without recompiling <literal>systemd-networkd</literal>.

Since the actual memory requirements depend on hardware, timing, exact
|
||
configurations etc. it isn't currently possible to infer a good default
|
||
from within the NixOS module system. Administrators are advised to
|
||
monitor the logs of <literal>systemd-networkd</literal> for <literal>rtnl: kernel receive buffer
|
||
overrun</literal> spam and increase the memory limit as they see fit.
|
||
</para>
|
||
<para>
|
||
Note: Increasing the <literal>ReceiveBufferSize=</literal> doesn't allocate any memory. It just increases
|
||
the upper bound on the kernel side. The memory allocation depends on the amount of messages that are
|
||
queued on the kernel side of the netlink socket.
