我遇到了错误无法在 Ubuntu 12.04.5 LTS 中通过套接字“/var/run/mysqld/mysqld.sock”连接到本地 MySQL 服务器。 所以我卸载mysql5.5来自 Ubuntu 12.04.5 LTS。但是当我尝试安装 mysql，我无法安装 mysql。
我使用以下命令来卸载 mysql：
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get remove --purge mysql-server-5.5 mysql-client-5.5 mysql-servercore-5.5 mysql-client-core-5.5
sudo apt-get autoremove
sudo apt-get autoclean
sudo rm -rf /var/lib/mysql
sudo rm -rf /etc/mysql
sudo deluser mysql
我使用以下命令来安装mysql 5.5：
sudo apt-get install mysql-server-5.5
sudo apt-get install mysql-server
但我遇到了以下错误：
AppArmor parser error for /etc/apparmor.d/usr.sbin.mysqld in /etc/apparmor.d/usr.sbin.mysqld at line 9: Could not open 'abstractions/mysql'
start: Job failed to start
invoke-rc.d: initscript mysql, action "start" failed.

dpkg: error processing mysql-server (--configure):

No apport report written because the error message indicates its a followup error from a previous failure.

mysql-server
E: Sub-process /usr/bin/dpkg returned an error code (1)
当我从终端输入“mysql”时，它返回错误：
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
我试过远程登录 127.0.0.1 3306谷歌搜索后，它返回连接被拒绝。
有人可以建议一个解决方案吗？
我运行sudo apt-get 安装 mysql 服务器并得到输出为：
