以MySQL- 5.7.18爲例:
sudo apt-get autoremove --purge mysql-server-5.7
#sudo apt-get remove mysql-server # 沒用到,已經沒有mysql-server
#sudo apt-get autoremove mysql-server # 沒用到,已經沒有mysql-server
sudo apt-get remove mysql-common
sudo rm -rf /etc/mysql/ /var/lib/mysql #很重要
#清理殘留數據
dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P
sudo apt autoremove
sudo apt autoreclean
執行dpkg -l |grep ^rc|awk ‘{print $2}’ |sudo xargs dpkg -P ,效果圖:
