解决方法:

删除mysql前先删除一下 /var/lib/mysql 还有 /etc/mysql

sudo rm /var/lib/mysql/ -R

sudo rm /etc/mysql/ -R

sudo apt-get autoremove mysql* --purge

sudo apt-get remove apparmor

sudo apt-get install mysql-server mysql-common

UBUNTU 彻底删除MYSQL 然后重装MYSQL

删除mysql

sudo apt-get autoremove --purge mysql-server-5.0

sudo apt-get remove mysql-server

sudo apt-get autoremovemysql-server

sudo apt-get remove mysql-common //这个很重要

上面的其实有一些是多余的。

清理残留数据

dpkg -l |grep ^rc|awk '{print $2}' |sudoxargsdpkg -P

安装mysql

sudo apt-get install mysql-server

sudo apt-get install mysql-client

sudo apt-get install php5-mysql

// 安装php5-mysql 是将php和mysql连接起来

一旦安装完成，MySQL 服务器应该自动启动。您可以在终端提示符后运行以下命令来检查 MySQL 服务器是否正在运行：

sudonetstat -tap | grepmysql

当您运行该命令时，您可以看到类似下面的行：

tcp 0 0 localhost.localdomain:mysql *:* LISTEN -

如果服务器不能正常运行，您可以通过下列命令启动它：

sudo /etc/init.d/mysql restart

进入mysql

$mysql -uroot -p 管理员密码

配置MySQL 的管理员密码：

sudomysqladmin -u root password newpassword
