# 一、基础配置 #

sudo mysql_secure_installation

*  step1

Securing the MySQL server deployment.
    Connecting to MySQL using a blank password.
    VALIDATE PASSWORD PLUGIN can be used to test passwords
    and improve security. It checks the strength of password
    and allows the users to set only those passwords which are
    secure enough. Would you like to setup VALIDATE PASSWORD plugin?
    
    Press y|Y for Yes, any other key for No:N
    
    Please set the password for root here.
    New password: 
    Re-enter new password:

*  step2

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. This is intended only for
    testing, and to make the installation go a bit smoother.
    You should remove them before moving into a production
    environment.
    
    Remove anonymous users? (Press y|Y for Yes, any other key for No) : N

*  step3

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) : N

*  step4

By default, MySQL comes with a database named 'test' that
    anyone can access. This is also intended only for testing,
    and should be removed before moving into a production
    environment.
    
    
    Remove test database and access to it? (Press y|Y for Yes, any other key for No) : N

*  step5

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

# 二、其他配置 #

## 1、设置mysql远程访问权限 ##

*  设置mysql的bind-address配置项

vim /etc/mysql/mysql.conf.d/mysqld.cnf
    # 修改bind-address
    bind-address		= 0.0.0.0

*  修改root的远程访问权限

mysql> update user set host = '%' where user = 'root';

注意：远程连接操作不应该修改mysql中user表中用户为root的记录，而是创建一条root记录；

mysql> CREATE USER 'root'@'%';
