Question

How to upgrade MySQL 5.5 to 5.6/5.7 or MariaDB 5.5 to 10.X on Linux?

Answer

This article provides instructions for upgrading MySQL 5.5 to 5.6/5.7 and MariaDB 5.5 to 10.0/10.1/10.2/10.3/10.4/10.5 on Linux.

Note: Upgrade can be performed in a command-line interface with the instructions below at your own risk. This task is supposed to be performed by a system administrator.
If you are not familiar with Linux system administering and would like our professionals to handle this task on your behalf, contact Professional Services team at https://www.plesk.com/professional-services/.

To find out your Linux distribution, run:

# plesk version | grep "OS version"

Or:

# cat /etc/*-release

Warning: MariaDB 10.4 and 10.5 are supported starting from Plesk Obsidian 18.0.30. Previous versions (Onyx and older) do not support MariaDB starting from 10.3 and there are no plans to implement it currently.

Warnings:
Direct upgrade from MySQL 5.1 to MySQL 5.6/5.7 will break tables structure. The instructions for upgrading MySQL from 5.1 to 5.5 on Linux are available here: How to upgrade MySQL from 5.1 to 5.5 on Linux

It is strongly recommended to create a server snapshot (full backup) before upgrading. Perform MySQL upgrade at your own risk.

Before starting a MySQL upgrade, stop the WatchDog service if it is used on a server. Check its status with the service watchdog status command.

Note: MySQL will not be upgraded on CentOS/RHEL-based operating systems if it was installed from the Webtatic Yum repository:

# rpm -qa | grep -i mysql
mysql55w-server-5.5.57-1.w6.x86_64

To start an upgrade of MySQL/MariaDB, connect to a server via SSH as root/superuser and follow the instructions for your operating system:

Plesk on CentOS 8

By default, CentOS 8 is shipped with MariaDB 10.3.

  1. For security reasons, create a database dump of all databases with the following command:

    # MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysqldump -u admin --verbose --all-databases --routines --triggers > /tmp/all-databases.sql

  2. Stop MariaDB:

    # service mariadb stop

  3. Remove additional package conflicting with 10.4 version:

    # yum remove mariadb-gssapi-server

  4. For security reasons, copy the database directory in a separate folder:

    # cp -v -a /var/lib/mysql/ /var/lib/mysql_backup

  5. Configure MariaDB repository: open the Setting MariaDB repositories page, select your OS distro, release, and desired MariaDB version. Once done, the configuration that should be added to the /etc/yum.repos.d/MariaDB.repo file will appear.

    Warning: MariaDB 10.4 and 10.5 are supported since 18.0.30, make sure the latest Plesk version is installed.

    Here is an example for MariaDB 10.4:

    5.1. Open/create the MariaDB.repo file in any text editor. In this example, we are using the vi editor:

    # vi /etc/yum.repos.d/MariaDB.repo

    5.2. Add the content below to the file:

    [mariadb]
    name = MariaDB
    baseurl = http://yum.mariadb.org/10.4/centos8-amd64
    gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
    gpgcheck=1
    priority=1
    module_hotfixes=1

    The configuration item module_hotfixes=1 is a workaround for what MariaDB told is a dnf bug. See MDEV-20673 for more details

    5.3. Save the changes and close the file.

  6. Reset all the cache:

    # yum clean all

  7. Start an upgrade of MariaDB to 10.4:

    # yum install MariaDB-server galera-4 MariaDB-client MariaDB-shared MariaDB-backup MariaDB-common

  8. Once the upgrade is finished, start MariaDB:

    # systemctl restart mariadb

  9. Upgrade MySQL databases:

    # MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql_upgrade -uadmin

  10. Restart mariadb service:

    # systemctl restart mariadb

  11. Execute this command to update the package version inside Plesk:

    # plesk sbin packagemng -sdf

  12. Restore SeLinux context:

    # restorecon -v /var/lib/mysql/*

Plesk on CentOS 7 / RHEL 7

By default, CentOS 7 is shipped with MariaDB 5.5. MariaDB 10.x version is a drop-in replacement for MySQL 5.5-5.7.

Automatic method

Note: The script will upgrade the default MariaDB 5.5 to the latest MariaDB version 10.5. Make sure Obsidian 18.0.30 or later is installed on the server.

  1. Download the attached script and provide it with executable rights:

    # wget https://plesk.zendesk.com/hc/article_attachments/360022419980/mariadb-10.5-upgrade.sh && chmod +x mariadb-10.5-upgrade.sh

  2. Execute the script via CLI:

    # ./mariadb-10.5-upgrade.sh

Manual Method

  1. For security reasons, create a database dump of all databases with the following command:

    # MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysqldump -u admin --verbose --all-databases --routines --triggers > /tmp/all-databases.sql

  2. Stop MariaDB:

    # service mariadb stop

  3. Remove additional mariadb-bench package if installed:

    # rpm -e --nodeps mariadb-bench

  4. For security reasons, copy the database directory in a separate folder:

    # cp -v -a /var/lib/mysql/ /var/lib/mysql_backup

  5. Check if the mysql-server package is already installed:

    # rpm -q --whatprovides mysql-server

    If it is installed and the command above gives output, remove using the following command:

    # rpm -e --nodeps `rpm -q --whatprovides mysql-server`

  6. Configure MariaDB repository: open the Setting MariaDB repositories page, select your OS distro, release, and desired MariaDB version. Once done, the configuration that should be added to the /etc/yum.repos.d/MariaDB.repo file will appear.

    Warning: MariaDB 10.4 and 10.5 are supported since 18.0.30, make sure the latest Plesk version is installed.

    Here is an example for MariaDB 10.5:

    6.1. Open/create the MariaDB.repo file in any text editor. In this example, we are using the vi editor:

    # vi /etc/yum.repos.d/MariaDB.repo

    6.2. Add the content below to the file:

    [mariadb]
    name = MariaDB
    baseurl = http://yum.mariadb.org/10.5/centos7-amd64
    gpgkey = https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
    gpgcheck=1

    6.3. Save the changes and close the file.

  7. Start an upgrade of MariaDB:

    # yum install MariaDB-client MariaDB-server MariaDB-compat MariaDB-shared

  8. Once the upgrade is finished, start MariaDB:

    # systemctl restart mariadb

    OR

    # systemctl restart mysql

  9. Upgrade MySQL databases:

    # MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql_upgrade -uadmin

  10. Restart mysql service:

    # systemctl restart mariadb

    OR

    # systemctl restart mysql

  11. Execute this command to update the package version inside Plesk:

    # plesk sbin packagemng -sdf

Note: After an upgrade, there may appear 'mysql' init script. It should be removed to avoid conflicts with MariaDB service. The same commands can be used to fix already existing conflict:

# systemctl stop mysql; killall mysqld # to stop the incorrect service if it is started
# rm /etc/init.d/mysql && systemctl daemon-reload # to remove the incorrect service script and reload systemctl configuration
# systemctl start mariadb # to start MariaDB if not started
# systemctl enable mariadb # to make sure that MariaDB will start after the server reboot automatically

Plesk on CloudLinux

  1. Create a backup of all databases with the following command:

    # MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysqldump -u admin --verbose --all-databases --routines --triggers > /tmp/all-databases.sql

  2. Stop the MySQL service:

    # service mysqld stop

  3. Copy a databases directory in a separate folder like this (for backup purposes also):

    # cp -v -a /var/lib/mysql/ /var/lib/mysql_backup

  4. Start the MySQL service:

    # service mysqld start

  5. Ensure that [mysqlclient] repository is enabled in
    /etc/yum.repos.d/cl-mysql.repo and the below command displays similar output:

    # yum repolist enabled | grep mysqlclient
    Repository extras is listed more than once in the configuration
    mysqclient/7/x86_64 mysqlclient 7

  6. Select MySQL/MariaDB version to install:

    Note: The following command does not work if governor-mysql package is not installed. In such case, install it:
    # yum install governor-mysql

    # /usr/share/lve/dbgovernor/mysqlgovernor.py --mysql-version=XXXXX

    Note: Where 'XXXXX' has to be substituted with one of the following:
    mariadb100 for MariaDB v10.0
    mariadb101 for MariaDB v10.1
    mariadb102 for MariaDB v10.2
    mariadb103 for MariaDB v10.3
    mariadb104 for MariaDB v10.4
    mariadb105 for MariaDB v10.5
    mysql55 for MySQL v5.5
    mysql56 for MySQL v5.6
    mysql57 for MySQL v5.7

  7. Install selected previously MariaDB engine:

    # /usr/share/lve/dbgovernor/mysqlgovernor.py --install

    Warning: CloudLinux does not recommend to downgrade from MySQL v5.6, MariaDB 10.x

  8. Restart MySQL:

    # service mysql restart

  9. Upgrade MySQL databases:

    # MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql_upgrade -uadmin

  10. Restart MySQL:

    # service mysql restart

  11. Execute the following commands to update package version inside Plesk:

    # plesk bin service_node --update local
    # plesk sbin packagemng -sdf

Plesk on Debian 9

Debian 9 is basically shipped with MariaDB. MariaDB 10.x version is a drop-in replacement for MySQL 5.5/5.6/5.7

Backup all existing databases using the KB article How to backup/restore a Plesk database dump and follow instructions on MariaDB site to update it:

Example for MariaDB 10.2

Install MariaDB:

Stop the MariaDB service:

# service mariadb stop

# curl -sS https://downloads.mariadb.com/MariaDB/mariadb_repo_setup | sudo bash -s -- --mariadb-server-version=mariadb-10.2

# apt install mariadb-server-10.2

If the installation fails with unmet dependencies:

dpkg: mariadb-server-10.1: dependency problems, but removing anyway as you requested:
plesk-mysql-server depends on virtual-mysql-server | mysql-server; however:
Package virtual-mysql-server is not installed.
Package mariadb-server-10.1 which provides virtual-mysql-server is to be removed.
Package mariadb-server-10.2 which provides virtual-mysql-server is not installed.

    Hello Mark S.

    You may try the solution from here (you will need to adapt it to Deb 10 instead of Deb 8): https://unix.stackexchange.com/questions/339563/upgrade-mariadb-10-0-29maria-1jessie-failed

    In case this won't help, contact OS support.

    Thank you for your answer. Unfortunately the described method in your link (adapted to Debian Buster) does not work either.

    This command is missing to make it work.

    1°) Open the MariaDB configuration file

    DEBIAN vi /etc/mysql/mariadb.conf.d/50-server.cnf

    REDHAT vi /etc/my.cnf

    2°) Add the line below [mysqld] section:

    plugin-load-add = auth_socket.so

    Is there any reason why this is not done in the course of a normal plesk update? I have 18.0 Obsidian installed - which supports MariaDb 10.3 natively - but this has never been updated since the first installation of the server. 

    As this also seems really verbose - is this still the recommended way for all versions? I mean why isn't it possible to upgrade this via Plesk Updates like any other 3rd party package?

    Sorry - this becomes annoying.

    Plesk writes that Moodle is a supported application - but today even a fresh install on a fresh system (Ubutu 18.04) is impossible. Again the famous non zero exit.

    Again the mariaDB version is too old. That's why at the beginning of the week my former debian server became unusable for moodle. Since days I try and try THESE linux hacking rubbish that don't want to apply. Now I sit in front of my fresh Ubuntu system with the same missing Moodle in these remote corona days and waste day after day with this mariaDB shit! 

    Please: ONE BUTTON, ONE UPDATE as it should be for Plesk users! Six pages reading tricks with endless links to source of sources to sources - sorry, NO!

    If Plesk supports Moodle I expect a real Plesk update without this not working hacks. Otherwise remove Moodle from the compatibility list. At the moment it neither be used nor installed. And that's the last thing I (and I guess a lot of others either) can need in these distancing days. Sorry for being a little harsh, but working help is needed urgently. And no: this is nothing for an additional purchasing of any Service. If the DB update will do as it should we would be done.

    Thanks

    Hi @Vinod Vyas,

    You need to find the command for a package manager that depends on your server OS. You may search in the internet for the proper command applicable for your OS as it is not managed by Plesk. For example, there are yum and rpm package managers used on Centos, CloudLinux or Red Hat OS and one of available commands would be the following:

    # rpm -qa | grep mariadb

    Hello Philipp Lang

    Thank you for the feedback. By design, MariaDB/MySQL server is installed from OS repositories unless custom isn't specified. 10.3 Maybe be installed with new Plesk Obsidian in case correct repos are set up on the server.

    > is this still the recommended way for all versions? 

    Yes, indeed, this is the only way to have MariaDB/MySQL. As long as you follow the process for your OS step by step, the process should go smoothly. 

    Feel free to vote for this feature suggestion: https://plesk.uservoice.com/forums/184549-feature-suggestions/suggestions/6315581-multiple-mysql-versions-configureable-over-panel

    Hello Dr. Michael Gellner

    Sorry for the long response and thank you for the feedback.

    To be honest, on your side I would feel the same.

    However, the only way to satisfy the requirements is to do the steps from this article manually.

    Usually, the process goes smoothly.

    If now you're stuck with some particular error, let us know, maybe some Pleskian already has a solution.

    Hello SamParis

    Thank you for noticing.

    According to https://jira.mariadb.org/browse/MDEV-14367 this happens when updating from MariaDB 10.1.

    However, this still may be useful for other Pleskians.

    # /usr/share/lve/dbgovernor/mysqlgovernor.py --mysql-version=mariadb105

    install-mysql: error: argument --mysql-version: invalid choice: 'mariadb105' (choose from 'auto', 'mysql51', 'mysql55', 'mysql56', 'mysql57', 'mysql80', 'mariadb55', 'mariadb100', 'mariadb101', 'mariadb102', 'mariadb103', 'mariadb104', 'percona56')

    Looks like a CloudLinux issue.
    MariaDB v 10.5 is not there yet

    Richard Anthony Secor Hi Richard, you are right. MariaDB 10.5 is not yet added to mysql-governor by CloudLinux .

    Hello Plesk Support Team,

    could you change this line in your documentation:

    # MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysqldump -u admin --all-databases --routines --triggers > /tmp/all-databases.sql

    to

    # MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysqldump -u admin --verbose --all-databases --routines --triggers > /tmp/all-databases.sql

    it shows what is happening. Better output better for large Databases doesn't seems to be frozen.

    Hello,
    I am trying to upgrade to mariadb 10.4 from Plesk Obsidian 18.0.30 on debian 9 and after adding the command # curl -sS https://downloads.mariadb.com/MariaDB/mariadb_repo_setup | sudo bash -s -- --mariadb-server-version=mariadb-10.4 get the following error: curl: (23) Failed writing body (395 != 1369)
    What could this be due to?

    Thank you

    Andreu Hi! on my debian 9 server it works fine. Which curl version are you running? My test server is running:

    # curl -V
    curl 7.52.1

     

    Please open a support ticket with us so we can take a look.

    Hi, it's only a minor point, but can the guidance notes for Ubuntu 18.04, which appear to be out of date (image) be corrected / updated? MariaDB 10.3.* is supported from Plesk Obsidian (any release) and MariaDB 10.4.* / 10.5.* are both now supported from Obsidian 18.0.30 release onwards. In addition, Ubuntu 20.04 OS is completely missing, yet that is now supported from Obsidian 18.0.29 release onwards too.

    Hi amazing Plesk support,

    in the past all upgrades were successful. This time it seems also, but in the end of installation MariaDB 10.5.5 to 10.3.24 on Ubuntu 18.04.5 and Plesk Obsidian 18.0.30 #1 I got the info that the installation failed. I went on for the last three steps by restarting and updating package version in Plesk. Then I looked in Plesk and the old version 10.3.x was shown. I performed the usual step clicking on localhost and simply clicking on OK on the next side.

    Then the new 10.5.5 version of MariaDB was shown and all websites/databases are working.

    But the fatal error already makes me unsure. Is everything okay now, or not.

    Greets and thanks for the tutorial.

    Hello Markus

    MariaDB upgrade to 10.5 with Ubuntu 18 was not yet tested. Please note that MariaDB upgrade is system administrative task. You may want to contact MariaDB Community support or wait for the article to be updated with steps for Ubuntu 18 and upgrade to 10.5

    Hello Ivan Postnikov

    Thank you very much. That's already much clearer than it was previously. Additional comments are:

    The warning about which Obsidian releases are suitable for which MariaDB releases is included in the Ubuntu 20.04 guide, but is missing from the Ubuntu 18.04 guide (image). It's therefore, still possible for somebody... using Ubuntu 18.04 to make a wrong assumption, as a result of that missing warning.

    The Plesk Changelog implies, but does not actually state, that MariaDB 10.4.* / 10.5.* are both now supported for all OS, from the Obsidian 18.0.30 release onwards (image) although, this page, is then given as the link for more detailed guidance. Users should therefore, come here to check & verify their own setup / intentions in advance. That's very good, but users are users, so it's not guarenteed!

    However, the last post from Anton Maslov then states "MariaDB upgrade to 10.5 with Ubuntu 18 was not yet tested" That's the ONLY reference for Ubuntu 18.04 users of this current status, anywhere on this page...i.e. That's not shown in the guide. This may also be the case for a MariaDB upgrade to 10.4.*  for Ubuntu 18.04 users.? Nobody knows, because it's not (yet) clearly stated anywhere in any guidance notes & not all users will read this comments section first. Therefore, there is still an unstated risk at this stage.

    FWIW, We currently use Ubuntu 18.04 LTS and we have had no problems at all, with the last two MariaDB upgrades within Plesk, when using this page for guidance. Now though, we can't yet / won't upgrade from MariaDB 10.3.* to MariaDB 10.4.* and/or MariaDB 10.5.*, becasue there's no confirmation from Plesk in the guideance section, well not yet :o)) that either of these upgrades will be fully successful (which means previously, they have actually been tested & verified by Plesk themselves)

    There's no need to publish this comment, as it's aimed purely for yourself Ivan Postnikov but it is much better for all concerned, if these missing details are very quickly added, because as you know MariaDB downgrades don't work / are not reccomended even by MariaDB themselves.

    Some Plesk users, who don't read any comments & only read the guidance sections on this page, if, they haven't taken a server snapshot backup or similar, prior to their MariaDB upgrade process, might inadvertently, make their own server and Plesk installation, totally unusable and irrecoverable.

    Can you also add Debian (10) Buster above? MariaDB update to 10.4 worked without complications. Unfortunately it is not clear from the article of MariaDB (DEB-files) if an update to version 10.5 under Debian Buster is also possible.

    Greetings

    Thanks a lot for answering, Anton Maslov. It's too late. I already performed the upgrade, seems to be successful. I performed the steps from the tutorial above. Apart from the install notice "Fatal error..." everything is running fine on 10.5.5. I had the same problem by upgrading from 10.2 to 10.3. So, if nothing bad will happen I'll run it until I change my server next year after three/four years.

    Hello,

    Mark S. 10.5 should also work fine. The article author will double-check it and add corresponding instructions.

    Learning Curve Thank you for the feedback. These points will be also reviewed and we'll look at how to improve the article.

    We have Obsidian 18.0.30  on Centos 7.8  and mariadb 5.65 (which is running) and yum

    BUT the directory /etc/yum.repos.d/ does not exist NOR does the file MariaDB.repo in fact

    we can't find that file anywhere on our dedicated server!

    So the instructions for Centos 7 just don't work??

    Instructions for Debian 10 were added.

    Sid B

    Typically /etc/yum.repos.d/ exists on CentOS server. Try creating the directory and file MariaDB.repo

    Permissions for yum.repos.d:
    drwxr-xr-x 2 root root 

    For MariaDB.repo:

    -rw-r--r-- 1 root root ... MariaDB.repo

    Also, we have a team which does such tasks for server owners on a paid basis: https://www.plesk.com/professional-services/administrative-services/

    @Sebastian Ayala,

    From the provided logs it looks that the previous version of MySQL wasn't removed properly.
    Please make sure that all steps from the guide were completed successfully.

    If not, feel free to submit the ticket to our Support Team.

    There maybe some speciifc fine details in the above guide for Ubuntu 18.04, that have yet to be added (at the time of this note; 13/10) but after some external research and some advance consulation with Plesk, we ran the upgrade process from MariaDB 10.3.* to 10.4.* and that went very smoothly. No issues, faults, warnings or errors when testing afterwards.

    We then, ran the upgrade process from MariaDB 10.4.* to MariaDB 10.5.* . Yes we could have just run the upgrade process from MariaDB 10.3.* to MariaDB 10.5.* and just omitted MariaDB 10.4.*, but one major release at a time, gave a much better recovery position (recoverable cloud server snapshot) if one was needed.

    Compared to previous releases, there are a few subtle MariaDB changes in MariaDB 10.5.* though, e.g.

    "...From MariaDB 10.4.6, mariadb is available as a symlink to mysql.
    From MariaDB 10.5.2, mysql is the symlink, and mariadb the binary name..."

    Plus, depending on your own install process choices, others things, including say; /etc/mysql/mariadb.cnf and etc/logrotate.d/mysql-server may need attention afterwards, but, Plesk were helpful in advance, so after some 'fine tuning' following the final upgrade; the Ubuntu 18.04.5 LTS / Obsidian 18.0.30 / MariaDB 10.5.6 combination is running like clockwork, with no issues, faults, warnings or errors. It was worth the effort.
