1 修改默认源为阿里源(国内源速度快，内容完整，并且可以自动解决依赖):
编辑以下文件，并且修改文件内容：
sudo vim /etc/apt/source.list
deb cdrom:[Ubuntu 16.04.3 LTS _Xenial Xerus_ - Release amd64 (20170801)]/ xenial main restricted deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
修改文件执行如下命令，更新源
sudo apt-get update
2 安装mysql
2.1安装软件
sudo apt-get install mysql-server mysql-client
sudo apt-get libmysqlclient-dev
2.2查看是否成功安装，执行以下命令，查看mysql是否成功安装
2.3验证，登录mysql
2.4 编辑mysql配置文件允许远程登录：
sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf
注释掉bind-address = 127.0.0.1：
然后进入mysql服务，执行授权命令：
grant all on *.* to root@'%' identified by '你的密码' with grant option;
flush privileges;
然后执行quit命令退出mysql服务，执行如下命令重启mysql：
service mysql restart
2.6 远程登录验证
现在在Windows下可以使用navicat远程连接Ubuntu下的MySQL服务：
