1.安装mysql

#更新apt-get库
sudo apt-get update

2.配置mysql

2.1 初始化mysql

VALIDATE PASSWORD PLUGIN can be used to test passwords...
Press y|Y for Yes, any other key for No: N 

#2
Please set the password for root here...
New password: 
Re-enter new password:

By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them...
Remove anonymous users? (Press y|Y for Yes, any other key for No) : N 

#4
Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network...
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y 

#5
By default, MySQL comes with a database named 'test' that
anyone can access...
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : N 

#6
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y 

3.配置远程连接

3.1修改user表

使用root用户进入mysql

sudo mysql -uroot -p

进入mysql表

use mysql;

查询user表中的user、host、plugin

select host,user,plugin from user;

结果如下：

将root用户的host、plugin改为%和mysql_native_password

update user set host='%' , plugin='mysql_native_password' where user='root';

flush privileges;

3.2 修改配置文件

找到/etc/mysql/mysql.conf.d/mysqld.cnf

vim /etc/mysql/mysql.conf.d/mysqld.cnf

注释掉#bind-address =127.0.01，或者将其修改为0.0.0.0

重启mysql服务
