Get MariaDB SQL Up and Running

If you read the previous article you will see that we installed the LAMP stack as is. We are going to be removing the MySQL component today and replacing it with MariaDB.

Remove MySQL

  1. Start the server in headless mode
    • right click the context menu
    • choose start headless
  2. SSH into it
  3. See what is installed
    dpkg --get-selections | grep -v deinstall >
  4. Open the file
    mysql-client-5.7 install
    mysql-client-core-5.7 install
    mysql-common install
    mysql-server install
    mysql-server-5.7 install
    mysql-server-core-5.7 install
    mysql-client-5.7 install
    mysql-client-core-5.7 install
    mysql-common install
  5. Remove these with apt-get remove
    • For the lazy and uncaring
         sudo apt-get remove  mysql* 
      sudo apt-get autoremove
  6. remove /etc/mysql
    • For the trusting and lazy (seriously be careful with any rm commands)
          sudo rm -Rf /etc/mysql
      sudo rm -Rf /var/lib/mysql
    • You might find more like:
      • /var/lib/mysql-5.7
      • /var/lib/mysql-files
      • /var/lib/mysql-keyrings

When that doesn’t work

sudo service mysql stop  #or mysqld
sudo killall -9 mysql
sudo killall -9 mysqld
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get autoremove
sudo apt-get autoclean
sudo deluser mysql
sudo rm -rf /var/lib/mysql
sudo apt-get purge mysql-server-core-5.5
sudo apt-get purge mysql-client-core-5.5
sudo rm -rf /var/log/mysql
sudo rm -rf /etc/mysql

Install MariaDB

sudo apt-get install --force-reinstall true mariadb-server
sudo mysql_secure_installation

Grant localhost

Fix the bind address
