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 10.0/10.1/10.2/10.3/10.4/10.5/10.6 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 later versions 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.

Warning:
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

Warning:
Direct upgrade from MariaDB 5.5 or 5.7 to MariaDB 10.6 or later versions is not possible.
You should first upgrade MariaDB 5.5. or 5.7 to any MariaDB from 10.3 to 10.5, and then perform an update to MariaDB 10.6 or later


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 later versions 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. In case upgrading to MariaDB 10.6 or newer it is needed to adjust the my.cnf configuration file to match the new requirements:

    # sed -i 's/bind-address = ::ffff:127.0.0.1/bind-address = 127.0.0.1/g' /etc/my.cnf

  9. Once the upgrade is finished, start MariaDB:

    # systemctl restart mariadb

  10. Upgrade MySQL databases:

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

  11. Restart mariadb service:

    # systemctl restart mariadb

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

    # plesk sbin packagemng -sdf

  13. 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 MariaDB 10.5 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://raw.githubusercontent.com/plesk/kb-scripts/master/c7-mariadb-10-5-upgrade/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 > /root/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 mariadb-server package is already installed:

    # rpm -q --whatprovides mariadb-server

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

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

  6. Configure MariaDB repository:

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

    Here is an example for MariaDB 10.5:

    6.1. The following command adds the MariaDB 10.5 repository:

    # curl -LsS https://r.mariadb.com/downloads/mariadb_repo_setup | sudo bash -s -- --mariadb-server-version=10.5

    Note: Make sure that other MariaDB repositories are not enabled in /etc/yum.repos.d/.

  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. In case upgrading to MariaDB 10.6 or newer it is needed to adjust the my.cnf configuration file to match the new requirements:

    # sed -i 's/bind-address = ::ffff:127.0.0.1/bind-address = 127.0.0.1/g' /etc/my.cnf

  10. start MariaDB:

    # systemctl restart mariadb

    OR

    # systemctl restart mysql

  11. Upgrade MySQL databases:

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

  12. Restart mysql service:

    # systemctl restart mariadb

    OR

    # systemctl restart mysql

  13. 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 -f /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 > /root/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. In case bind-address directive is present in /etc/my.cnf make sure that it is as follows :

    # bind-address = 127.0.0.1

  5. Start the MySQL service:

    # service mysqld start

  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
    mariadb106 for MariaDB v10.6
    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.

    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

    HI,

    I have installed Obsidian and now some client has problem to import Database (utf8_unicode_520_ci). Your raccomended instruction ist to upgrade MariaDB.Questions:

    - can I use with Obsidian and install from Red Hat Softwer Collection the MariaDB10.3?

    - can I migrate  MariaDB 5.5.64 direct to MariaDB 10.3? On RedHat Manual they raccomand to migrate to Version 10 at first and than to 10.3    https://access.redhat.com/documentation/en-us/red_hat_software_collections/3/html/3.3_release_notes/chap-migration

    - can I use your instrution for Cento OS to migrate to MariaDB 10.3

    Thanks in advice

    Hi Gilberto,


    For RedHat please follow their guide. Direct upgrade from 5.5 to 10.3 not recommended.

    Hello, just upgraded my MariaDB from 5.5 to 10.3 on Plesk Obsidia 18.0.21 and it worked just great..Took me 5 minutes and all websites are working just fine and i believe faster. I upgraded because i believe that 5.5 was causing some freezes on some queries that included SELECT DISTINCT..That happened a lot of times lately, so i hope this gets fixed..i believe it was about Copying tmp tables, or Waiting for table lock isues

    I guess some of the steps are related to the change from mysql to mariadb, right?

    If we consider that we are changing from mariadb 5.5 to mariadb 10.3, in Centos 7.7, could the summary of the steps be like I show below?

    ----------------------

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

    service mariadb stop

    rpm -qa | grep mariadb

     ==> rpm -e --nodeps <other-mariadb-package>

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

    rpm -q --whatprovides mariadb-server

    rpm -e --nodeps `rpm -q --whatprovides mariadb-server`

     

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

    [mariadb]

    name = MariaDB

    baseurl = http://yum.mariadb.org/10.3/centos7-amd64

    gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB

    gpgcheck=1

     

    yum install MariaDB-server MariaDB-client

    systemctl restart mariadb

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

    systemctl restart mariadb

    plesk sbin packagemng -sdf

    --------------------------------------

     

    My maridb related packages are:

    plesk-libmariadbclient-3.0-3.0.9-1centos.7.190417.1743.x86_64
    mariadb-libs-5.5.64-1.el7.x86_64
    sw-mariadb-client-1.0.0-centos7.17031417.x86_64
    mariadb-server-5.5.64-1.el7.x86_64
    plesk-libmariadbclient-1.0-1.0.0-1centos.7.190329.1026.x86_64
    mariadb-5.5.64-1.el7.x86_64

     

    So I guess I don't need to uninstall any of them individually, right? I guess with the command "rpm -e --nodeps `rpm -q --whatprovides mariadb-server`" they will be uninstalled

     

    If we follow all these steps, what should we do if something fails and we need to restore the previous version?

    Hi Nerque that is correct, you may skip this part:

    rpm -q --whatprovides mariadb-server

    rpm -e --nodeps `rpm -q --whatprovides mariadb-server`

    Since you are already running mariadb you do not need to remove mysql.

    First of all, thanks for the answer.

    If it is not necessary to uninstall the current version of MariaDB (5.5), could I update MariaDB, instead of uninstalling the old version and installing the new one(10.3)?

    I understood from some site that it was not recommended, and that it was better to uninstall version 5.5 and then install version 10.3. I don't know if that's true.

    If an upgrade were possible, I suppose the steps would be:

    -------------------------------------------------

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

    service mariadb stop

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

     

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

    [mariadb]

    name = MariaDB

    baseurl = http://yum.mariadb.org/10.3/centos7-amd64

    gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB

    gpgcheck=1

     

    yum -y upgrade maria*

    systemctl restart mariadb

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

    systemctl restart mariadb

    plesk sbin packagemng -sdf

    -----------------------------------------

    Is this all right?

     

    And, although a copy of the databases is made, with the dump and copy of the mysql folder, I am not very clear about the process to recover it in case of disaster. Uninstall MariaDB 10.3, remove the repo file, reinstall the default version of centos, restore mysql folder and then recover the dump? Would this be the right order? Is it necessary to restore the mysql folder or is it enough to recover the dump?

     

    Thank you in advance

    Since message approval takes a long time, I tried to perform the actions I listed above, and some recommended from other sites, by uninstalling mariadb 5.5, just in case.

    ------------------------------------------------------

    mysqldump -u admin -p`cat /etc/psa/.psa.shadow` --all-databases --routines --triggers > ~/backup/all-databases.sql

    for DB in $(mysql -uadmin -p`cat /etc/psa/.psa.shadow` -B -e "show databases" -s --skip-column-names); do
        mysqldump -u admin -p`cat /etc/psa/.psa.shadow` $DB > ~/backup/$DB.sql
    done

     

    mysql -uadmin -p`cat /etc/psa/.psa.shadow` -B -e "SET GLOBAL innodb_fast_shutdown=0;"

    systemctl stop monit.service

    systemctl disable mariadb

    systemctl stop mariadb

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

    cp /etc/my.cnf ~/backup/

    cp -v -a /etc/my.cnf.d/ ~/backup/

    rpm -e --nodeps `rpm -q --whatprovides mariadb-server`

     

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

    [mariadb]

    name = MariaDB

    baseurl = http://yum.mariadb.org/10.3/centos7-amd64

    gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB

    gpgcheck=1

     

    yum install MariaDB-server MariaDB-client MariaDB-shared MariaDB-backup MariaDB-common

    systemctl enable mariadb

    systemctl restart mariadb

    mysql_upgrade -uadmin -p`cat /etc/psa/.psa.shadow`

    systemctl restart mariadb

    plesk sbin packagemng -sdf

    mysql -uadmin -p`cat /etc/psa/.psa.shadow` -B -e "SELECT VERSION();"

    systemctl restart monit.service

    ------------------------------------------------------

     

    And... apparently, everything's fine. All the websites are working as before... Good.

    Hello Kingsley Felix

    Thank you for the feedback.

    In that case, feel free to do it on your side, following steps from this article, as confirmed by other Pleskians, steps for 10.3 are identical.

    Warning: MariaDB 10.3 is supported starting from Plesk Obsidian. Previous versions (Onyx and older) do not support MariaDB 10.3. For details, visit this link.

    I have followed this Article. 

    Everything went fine but the Mysql version still shows to be 5.5?

     

    What did I do wrong?

    Hello Rashid Qureshi,

    Most probably, you haven't executed this command at the end:

    # plesk sbin packagemng -sdf

    Hi there!

    Thanks for providing this, i used to update MariaDB 5.5.65 on CentOS 7 to MariaDB 10.3, latest stable supported by Plesk.

    Everything went smoothly and no errors so far, however i didn't understand what you mean on the last step:

    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.

    What is " 'mysql' init script", is it an error message that appears on the SSH window, on Plesk, on an error log?

    Should i run those final steps anyway?

    # 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

    Thanks!

    Hello Necro

    > What is " 'mysql' init script"

    This is a leftover from previously installed MySQL server. Init script is a script for a service to start on boot.

    > Should i run those final steps anyway?

    The last step is required to make sure the processes of old MySQL version are stopped, to start MariaDB if not started, and to make sure that MariaDB will start after the server reboot. I would recommend not avoiding it.

    Ok thanks Ivan!!

    It already seems that Plesk is running much faster on MariaDB 10.3 than on previous 5.5 👍

    Do we need to secure MariaDB? I was reading a tutorial (https://linuxize.com/post/install-mariadb-on-centos-7/) that recommended to run the mysql_secure_installation script which will perform several security related tasks like set up the root user password, remove the anonymous user, restrict root user access to the local machine, and remove the test database.

    Or does Plesk takes care of this already?

    Thanks again!

    Hello Necro

    It's recommended to stay with the configuration, predefined by Plesk.

    Also, here're general recommendations for securing Plesk installation: https://support.plesk.com/hc/en-us/articles/115000626925

    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

    Hello, I just wanted to update MariaDB to version 10.3.23 under Debian 10. So far all good, after the installation there were errors on an apt --fix-broken install but results in:

    dpkg: regarding .../mariadb-client-core-10.3_1%3a10.3.23+maria~buster_amd64.deb containing mariadb-client-core-10.3:
    mariadb-client-10.3 conflicts with mysql-client-core-5.5
    mariadb-client-core-10.3 provides mysql-client-core-5.5 and is to be installed.

    E: Sub-process /usr/bin/dpkg returned an error code (1)

    Any ideas? If I look at https://packages.debian.org/search?lang=de&searchon=names&keywords=mysql-server-core, the package "mysql-server-core-5.5" for buster does not exist.

    Hi Ivan

     

    I think you mean Tools & Settings > Server Components? I tried that already but that doesn't resolve the issue unfortunately. I'll submit a support request instead. Cheers
