如果有人可以帮助您。我已经尝试删除mysql服务器，它告诉了我。

将英语翻译添加到日志文件：

看来您的apparmor配置文件中存在mysql错误。修复它时，可以为mysql禁用apparmor配置文件，并且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

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

UPDATE2：

删除并重新安装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

（应要求一个新的管理员密码）

检查是否有效：

sudo service mysql status

如果不起作用，请检查是否有文件/etc/mysql/my.cnf。如果不是，请从默认目录复制它，然后重新启动mysql：

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

我相信这与以下问题有关：https : //bugs.launchpad.net/ubuntu/+source/mysql-dfsg-5.1/+bug/375371 https://bugs.launchpad.net/ubuntu/+source/mysql -dfsg-5.0 / + bug / 227615

我必须更改mysql使用的tmp目录的位置：

编辑/etc/mysql/my.cnf

更改：

tmpdir      = /tmp

至：

tmpdir      = /var/tmp/mysql

并确保您创建该目录并适当设置权限：

sudo mkdir -m 0770 /var/tmp/mysql
sudo chown mysql:mysql /var/tmp/mysql

然后，您可以尝试重新安装，它应该可以工作（对我来说很好）：

sudo apt-get install -f
