解决方法:
删除mysql前 先删除一下 /var/lib/mysql 还有 /etc/mysql
sudo rm /var/lib/mysql/ -R sudo rm /etc/mysql/ -R
sudo apt-get autoremove mysql* --purge sudo apt-get remove apparmor
sudo apt-get install mysql-server mysql-common
UBUNTU 彻底删除 MYSQL 然后重装 MYSQL
删除mysql
sudo apt-get autoremove --purge mysql-server-core-5.5
sudo apt-get remove mysql-server
sudo apt-get autoremove mysql-server
sudo apt-get remove mysql-common //这个很重要 上面的其实有一些是多余的。
清理残留数据
sudo dpkg -l |grep ^rc|awk ‘{print $2}‘ |sudo xargs dpkg -P
