Debian系統升級MariaDB的流程如下：
mysqldump工具備份所有數據庫，避免數據丟失。mysqldump -u root -p --all-databases > full_backup.sql
mysql命令確認當前MariaDB版本。mysql -u root -p -e "SELECT VERSION();"
wget https://downloads.mariadb.org/MariaDB/mariadb_repo_setup
sudo dpkg -i mariadb_repo_setup.deb
sudo apt update
apt命令升級軟件包。sudo apt upgrade mariadb-server
sudo systemctl restart mariadb
mysql -u root -p -e "SELECT VERSION();"
mysql -u root -p < full_backup.sql
