mysql-community_5.7.9-1ubuntu14.04_amd64.changes  

mysql-testsuite_5.7.9-1ubuntu14.04_amd64.deb


更新设置到最新系统：
sudo apt-get update
sudo apt-get upgrade
apt-get install libaio1

然后分别安装以下的包：
sudo dpkg -i mysql-common_5.7.9-1ubuntu14.04_amd64.deb
sudo dpkg-preconfigure mysql-community-server_5.7.9-1ubuntu14.04_amd64.deb
此步需要输入数据的root密码

sudo dpkg -i libmysqlclient20_5.7.9-1ubuntu14.04_amd64.deb
sudo dpkg -i libmysqlclient-dev_5.7.9-1ubuntu14.04_amd64.deb
sudo dpkg -i libmysqld-dev_5.7.9-1ubuntu14.04_amd64.deb
sudo dpkg -i mysql-client_5.7.9-1ubuntu14.04_amd64.deb
sudo dpkg -i mysql-community-client_5.7.9-1ubuntu14.04_amd64.deb
sudo dpkg -i mysql-common_5.7.9-1ubuntu14.04_amd64.deb

sudo apt-get -f install
此步为了安装依赖包 libmecab2

sudo dpkg -i mysql-community-server_5.7.9-1ubuntu14.04_amd64.deb
sudo dpkg -i mysql-server_5.7.9-1ubuntu14.04_amd64.deb

这时数据安装完成，并自动启动


查看mysql安装的路径和依赖：

whereis mysql

mysql: /usr/bin/mysql /etc/mysql /usr/lib/mysql /usr/include/mysql /usr/share/mysql /usr/share/man/man1/mysql.1.gz

这时你会发现 mysql以服务形式自启动
