Answer 1

您的 mysql apparmor 配置文件中似乎有错误。在修复它时，您可以禁用 mysql 的 apparmor 配置文件，mysql 应该可以工作：

sudo ln -s /etc/apparmor.d/usr.sbin.mysqld /etc/apparmor.d/disable/usr.sbin.mysqld

并使用以下命令重新启动 apparmor： sudo /etc/init.d/apparmor restart

当您修复了 mysql apparmor 配置文件后，您可以删除符号链接并重新启动 apparmor。

更新2：

删除和重新安装mysql的新步骤：

sudo apt-get purge mysql-server mysql-client mysql-common mysql-client-5.5 mysql-server-5.5
sudo apt-get autoremove
sudo apt-get autoclean

sudo rm -rf /etc/mysql

sudo apt-get install mysql-server mysql-common mysql-client

（应该要求一个新的管理员密码）

检查它是否有效：

sudo service mysql status

如果它不起作用，请检查您是否有文件/etc/mysql/my.cnf。如果没有，从默认的复制它并重新启动mysql：

sudo cp /etc/mysql/my.cnf.dpkg-dist /etc/mysql/my.cnf
