ubuntu16.04 彻底卸载MySQL

 

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

 启动、关闭服务和查看运行状态

sudo service mysql start
sudo service mysql stop
sudo service mysql status
