通过在本页上翻找，找到如下的连接 [ http://dev.mysql.com/doc/mysql-apt-repo-quick-guide/en/ ]
这个页面与指导用户如何去安装mysql对应得不同版本的信息

wget   http://dev.mysql.com/get/mysql-apt-config_0.3.6-1debian8_all.deb dpkg -i  mysql-apt-config_0.3.6-1debian8_all.deb
在弹出的页面选择使用apply模式，这会将一些资源的网址写入到source-list文件中去
之后进行
sudo apt-get update
对制定版本的安装
sudo apt-get install mysql-server-5.6

1.先去修改my.cnf的配置文件
2.关闭mysql
3.启动mysqld_safe &
4.使用mysql_install_db
5.对于初始化的数据库要进行密码修正，主要是mysqladmin
6.然后重启服务
若其中出现问题，请即刻去查看一下 /var/log/mysql/error.log
sudo /usr/bin/mysqladmin -u root password 'root'
sudo /usr/bin/mysql_install_db --user=mysql --basedir=/usr/ --datadir=/mnt/mysql
然后启动mysqld_safe &
在启动mysql就可以了

sudo service mysql restart
sudo service mysql stop
sudo service mysql start
sudo /etc/init.d/mysql start | stop | restart
