以MySQL- 5.7.18为例:
sudo apt-get autoremove --purge mysql-server-5.7 #sudo apt-get remove mysql-server # 没用到,已经没有mysql-server #sudo apt-get autoremove mysql-server # 没用到,已经没有mysql-server sudo apt-get remove mysql-common sudo rm -rf /etc/mysql/ /var/lib/mysql #很重要 #清理残留数据 dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P sudo apt autoremove sudo apt autoreclean
执行dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P ,效果图:
安装MySQL:
sudo apt-get install mysql-server sudo apt-get install mysql-client sudo apt-get install libmysqlclient-dev
