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.
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
Execute the script via CLI:
# ./c7-mariadb-10-5-upgrade.sh
Manual Method
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
Stop MariaDB:
# service mariadb stop
Remove additional
mariadb-bench
package if installed:# rpm -e --nodeps mariadb-bench
For security reasons, copy the database directory in a separate folder:
# cp -v -a /var/lib/mysql/ /var/lib/mysql_backup
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`
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/
.Reset all the cache:
# yum clean all
Start an upgrade of MariaDB:
# yum install MariaDB-client MariaDB-server MariaDB-compat MariaDB-shared
- 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
start MariaDB:
# systemctl restart mariadb
OR
# systemctl restart mysql
Upgrade MySQL databases:
# MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql_upgrade -uadmin
Restart mysql service:
# systemctl restart mariadb
OR
# systemctl restart mysql
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
