====》至于为什么出现这个 '/var/run/mysql/mysqld.sock'，原因未知。
问题解决方法，


1. 先解决 你如下出现的安装包依赖项的问题
sudo apt-get autoclean
sudo apt-get update


sudo dpkg --configure -a
sudo apt-get -f install


sudo apt-get install libc6-dev-i386


2. 干净删除 现有的 mysql


sudo apt-get autoremove mysql-server
sudo apt-get remove mysql-common
dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P


3. 再重新安装


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


4. 重启 mysql  服务程序


sudo /etc/init.d/mysql restart


5. 现在可正常使用
mysql -uroot -p
