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 below is applicable only for upgrading default MariaDB 5.5 to the latest MariaDB version, for other cases apply the steps from the Manual Method section. 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://support.plesk.com/hc/en-us/article_attachments/4584125667858/c7-mariadb-10.5-upgrade.sh && chmod +x c7-mariadb-10.5-upgrade.sh

  2. Execute the script via CLI:

    # ./c7-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:

    CONFIG_TEXT: [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. Reset all the cache:

    # yum clean all

  8. Start an upgrade of MariaDB:

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

  9. Once the upgrade is finished, start MariaDB:

    # systemctl restart mariadb

    OR

    # systemctl restart mysql

  10. Upgrade MySQL databases:

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

  11. Restart mysql service:

    # systemctl restart mariadb

    OR

    # systemctl restart mysql

  12. 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

  1. 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

  1. Install MariaDB:

    1.1. 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:

    CONFIG_TEXT: 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.
    Package mysql-server is not installed.

    Depends: mariadb-server-core-10.2 (>= 10.2.19+maria~stretch) but it is not going to be installed

    Run the command below to correct them:

    # apt --fix-broken install

  2. Check MySQL version:

    # mysql -V
    mysql Ver 15.1 Distrib 10.2.19-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

  3. Start the MariaDB service:

    # service mariadb start

    Note: It may be already started

  4. Upgrade MySQL databases:

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

  5. Restart mysql service:

    # service mariadb restart

    Dear Ivan,

    thanks for pointing out the easy way to disable the repo.

    When login into the server back-end this morning. Plesk wants to update the MySQL server! When I go to the Plesk page: "available updates", it shows me the following updates:

    MariaDB-client 10.2.27-1.el7.centos (mariadb) MariaDB: to 10.2.28-1.el7.centos aktualisieren (mariadb)
    MariaDB-common 10.1.42-1.el7.centos (mariadb) MariaDB: to 10.2.28-1.el7.centos aktualisieren (mariadb)
    MariaDB-server 10.2.27-1.el7.centos (mariadb) MariaDB: to 10.2.28-1.el7.centos aktualisieren (mariadb)
    MariaDB-shared 10.1.42-1.el7.centos (mariadb) MariaDB: to 10.2.28-1.el7.centos aktualisieren (mariadb)

    How do I get rid of this? Because when running der yum update on cli, it shows that there are no updates.

    The version installed is:
    [root@example ~]# rpm -q --whatprovides mysql-server
    MariaDB-server-10.2.27-1.el7.centos.x86_64
    MariaDB-server-10.2.27-1.el7.centos.x86_64

    thx Alexander

    Mark S.

    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/

    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??

    Hi,

    After upgrading mariadb from version 10.1 to 10.3 on debian 9.12 plesk does not seem to recognize the mysql service anymore under server components and says "The component was not installed". Everything seems to be working fine though and under "Database Servers" the new version seems in place. I followed the procedure for debian 8/9 in this article and executed the commands to update the package version inside plesk. Below you can find more details regarding my configuration:

    mysql Ver 15.1 Distrib 10.3.23-MariaDB, for debian-linux-gnu (x86_64)

    Plesk Obsidian Web Host Edition
    Version 18.0.27 Update #1

    Thank you in advance for your reply! Cheers

    i've read the changelog nothing spezial there ... ok it was risky but its my development and test-server where i did it... mariabdb 10.4 works very well.

    Some advantages are:

    DoS Protection
    Bruteforce Detection

    Plesk should support the newest version officially.

    @Jonathan instead of 'service mariadb stop' you can try to run 'systemctl stop mariadb.service'. As for 'yum repolist', as it is described in "For CentOS 7" section of this article, make sure you create `/etc/yum.repos.d/MariaDB10.1.repo` file with the corresponding content.

    Hello @Alejandro Stendelis,

    Try to clean up the list of the mirrors.

    1. Install yum utils:
    # yum install yum-utils

    2. Run the following command:
    # yum clean all

    If the issue still persists, please submit the ticket and we investigate the issue:
    How to submit a request to Plesk support?

    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

    For Information (may be useful to some other users). At the time of making this specific post, we're now running: Ubuntu 18.04.3 LTS / Plesk onyx 17.8.11 / MariaDB 10.3.17 with no issues or problems (Plesk or MariaDB)

    We needed to upgrade from MariaDB 10.2.* to MariaDB 10.3.* for some of the domains that we host, due to the software they run. Not wanted... Needed! Yes MariaDB 10.2.* is still a stable MariaDB release, but is too old now for some applications, plus MariaDB 10.3.* & MariaDB 10.4.* specifically, offer lots more improved functionality.

    Waiting for Plesk Obsidian to finally be released at 'early adopter' status was/is still not an option for us. FWIW If Obsidian is NOT released c/w full Plesk support for MariaDB 10.4.* then serious questions need to be asked!! Plesk avoiding 'officially supporting' latest, stable releases, mainly, due to lack of advance testing time? Hmmm

    Back to the MariaDB 10.2.* to MariaDB 10.3.* upgrade. We posted a Plesk support ticket to try and treble check everything that we could in advance and the support team were extremely helpful. We ran the upgrade, tested everything, then restored a snapshot to take the server back to the Pre-MariaDB upgrade status. We then asked more specific questions (all of which, again, were very helpfully answered by the support team) but then we waited for the next Plesk 17.8.11 update before proceeding any further. Why? That's becasue we wanted to upgrade MariaDB, but, also, wanted to then test that setup by running a Plesk update too, before taking anything / everything live. That we did & there were no issues. The Plesk 17.8.11 update on our Ubuntu 18.04.3 LTS / MariaDB 10.3.17 setup ran perfectly, with no problems, which was nice & this completed our pre-live testing.

    MariaDB 10.3.* on Plesk 17.8.11 is still not 'offcially supported' (and most likely, never will be now) but on our current server / domains / software setup it's all good & fingers crossed, we're satisfied with everything so far!

    Hello @Artur Beqiraj

    We recommend upgrading to MariaDB 10.1 at least. There is no significant difference, however, it will be easier to install MariaDB 10.1 or 10.2

    Hi Great guys,

    I install Mysql in the  AWS linux server, it is version mysql Ver 15.1 Distrib 5.5.68-MariaDB, for Linux (x86_64) using readline 5.1  (exported by Mysql -V).

    But I want upgrade 5.5.68-MariaDB to 10.3+ MarinaDB . In my server has no /etc/psa/.psa.shadow  folder and file. I tried to run the commands but there are many error. Could you tell me what I should to do please ? Thank you so much !

    You could try using --skip-broken to work around the problem
    You could try running: rpm -Va --nofiles --nodigest

    It didn't work for me in 100%.

    I was upgrading MySQL 5.1 to 5.7 om my CentOS 6 and I couldn't start mysql.

    # service mysqld start - gave me nothing, even no single line in /var/log/mysqld.log.

     

    What I did:

    1. I started mysql service from a file /usr/sbin/msqld to check what a problem was

    2. The problem was in config file /etc/my.cnf

    [ERROR] unknown variable 'innodb_additional_mem_pool_size=500K'

    I had to comment this line.

    3. After that I had a problem with access to the user table. 

    [ERROR] Fatal error: mysql.user table is damaged. Please run mysql_upgrade.

    mysqld --skip-grant-tables - it starts without reading the user table

    mysql_upgrade - then I could upgrade my tables

    killall mysqld - killing all the mysql instances

    4. Finally 

    # service mysqld start

    Hello giuseppe amodio,

    Thank you for your comment. I've re-tested the script on a test server. It is possible to execute it as Superuser using the 'sudo ./c7-mariadb-10.5-upgrade.sh' command. 
    So the following statement from the article is correct:

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

    There is an error in the attached script.
    This doesn't do anything, the files and directories are copied to /dev/null

    echo "creating backup of mysql directory"
    cp -v -a /var/lib/mysql/ /var/lib/mysql_backup 2&> /dev/null

    It should be something like this, copying the errors to /dev/null

    echo "creating backup of mysql directory"
    cp -v -a /var/lib/mysql/ /var/lib/mysql_backup 2> /dev/null

    If I remember correctly, the "exclude=MariaDB" resulted from a situation where an automatic update updated MariaDB to a version that failed with certain database attributes and was shortly revoked after publication. At that time the advice was to exclude MariaDB from automatic updates (from Yum respectively). So indeed, this is an "extra" user-driven configuration that is not the MariaDB or Yum default.

    Hello Carlos Lopez,

    To update to MariaDB 10.6 on Centos 7 you will need to apply the Manual Solution for Centos 7. In step 6 it will be required to open the Setting MariaDB repositories page, select your OS distro, release, and desired MariaDB version, and place the provided output to the `/etc/yum.repos.d/MariaDB.repo` file as per steps 6.1 and 6.2.

    What exactly did not work, e.g. what error messages have been displayed? Was "yum clean all" your solution?

    Hi Julian,

    Are you on CentOS 7?  Maybe something changed recently then.  The last few times I've installed updates they go in and create the file.  A few months later, maybe, we install a kernel update and restart the server.  Even after that the "mysql" service is running and is MariaDB like I said, so I don't immediately notice anything wrong.  But we have a nightly script that runs "/bin/systemctl stop mariadb.service" and "/bin/systemctl start mariadb.service" to copy the raw MySQL files (in addition to an export), and the start fails because "mysql" is already running.  It caught me a couple times in the past year, so I thought I'd post about it for others.

    I am unable to upgrade from MariaDB 10.1 to 10.2. I get this error:

    This is a brief description of the upgrade process. Important details

    Hi on Ubuntu 18.04 bionic... I followed your procedure and had 2 issues :
    1) mirror.truenetwork.ru is not responding, I used sfo1.mirrors.digitalocean.com instead (found on mariadb.com)
    2) apt-get install gave me : "mariadb-server : Depends: mariadb-server-10.5" "Unable to correct problems, you have held broken packages". I googled and solved this by :

    curl -sS https://downloads.mariadb.com/MariaDB/mariadb_repo_setup | sudo bash
apt update
apt upgrade
apt remove mysql-common
apt install mariadb-server

    found on stackoverflow.com.

    Then after first start of mariadb service I had 2 errors messages, but this was only for the first start before the end of the procedure... finger cross ;-)
