人家写的很详细了，我这里记录一下我自己的操作过程

1.  停止 mysql 服务 sudo service mysql status sudo service mysql stop
2.  查询 mysql 依赖 :~$ dpkg --list|grep mysql
    
        ii  dbconfig-mysql                        2.0.9                                      all          dbconfig-common MySQL/MariaDB support
         ii  mysql-client-5.7                      5.7.25-0ubuntu0.18.04.2                    amd64        MySQL database client binaries
         ii  mysql-client-core-5.7                 5.7.25-0ubuntu0.18.04.2                    amd64        MySQL database core client binaries
         ii  mysql-common                          5.8+1.0.4                                  all          MySQL database common files, e.g. /etc/mysql/my.cnf
         ii  mysql-server                          5.7.25-0ubuntu0.18.04.2                    all          MySQL database server (metapackage depending on the latest version)
         ii  mysql-server-5.7                      5.7.25-0ubuntu0.18.04.2                    amd64        MySQL database server binaries and system database setup
         ii  mysql-server-core-5.7                 5.7.25-0ubuntu0.18.04.2                    amd64        MySQL database server binaries
         ii  php-mysql                             1:7.2+60ubuntu1                            all          MySQL module for PHP [default]
         ii  php7.2-mysql                          7.2.15-0ubuntu0.18.04.2                    amd64        MySQL module for PHP
3.  逐个卸载 sudo apt-get remove mysql-common 出错了！
    
        The following packages have unmet dependencies:
          	dbconfig-mysql : Depends: default-mysql-client but it is not going to be installed or
                                    virtual-mysql-client
         E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
    
    sudo apt-get autoremove --purge mysql-server-5.7 sudo apt-get autoremove --purge mysql-server-core-5.7 sudo apt-get autoremove --purge mysql-client-5.7 sudo apt-get autoremove --purge mysql-client-core-5.7 再来 sudo apt-get remove mysql-common
4.  清除残留 dpkg -l |grep ^rc|awk '\{print $2\}' |sudo xargs dpkg -P
    
    sudo apt autoremove
    
    我这里没有什么数据，使用认为以下必要删除 sudo rm -rf /etc/mysql/ /var/lib/mysql 实际环境下还是小心为好！
