#### 下载安装 ####

sudo apt install mysql-server
    mysql --version

#### 运行安全脚本 mysql\_secure\_installation ####

安全脚本主要做如下事项，根据自己情况设置即可：

*  为root用户设置密码
 *  删除匿名账号
 *  取消root用户远程登录
 *  删除test库和对test库的访问权限
 *  刷新授权表使修改生效

lazycece@cc-ubuntu:~$ sudo mysql_secure_installation 
    
    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: 
    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
    
     ... skipping.
    
    
    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
    
     ... skipping.
    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
    
     ... skipping.
    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) : 
    
     ... skipping.
    All done!
