NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we'll need the current
password for the root user.  If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

Set root password? [Y/n] Y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!


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? [Y/n] Y
 ... Success!

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? [Y/n] Y
 ... Success!

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? [Y/n] Y
 - Dropping test database...
ERROR 1008 (HY000) at line 1: Can't drop database 'test'; database doesn't exist
 ... Failed!  Not critical, keep moving...
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] Y
 ... Success!




All done!  If you've completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL!

几个需要设置的地方如图所示:

阿里云 centos7 安装mysql

具体说明如下:

  • Set root password? [Y/n] 
    是否设置root用户的密码

  • Remove anonymous users? [Y/n] 
    是否删除匿名用户

  • Disallow root login remotely? [Y/n] 
    是否禁止root远程登录

  • Remove test database and access to it? [Y/n] 
    是否删除database数据库

  • Reload privilege tables now? [Y/n] 
    是否重新加载授权信息

MySQL安装完成后,此时的MySQL外网是无法访问的:

阿里云 centos7 安装mysql


可以看到 user 为 root,host 为 localhost 的话,说明 MySQL 只允许本机连接,那么外网,本地软件客户端就无法连接了。

解决方案


执行如下命令:

update user set host='%' where user ='root';
flush privileges;

查看是否修改正常:

阿里云 centos7 安装mysql

对于设置其他用户远程连接的方法:

GRANT ALL PRIVILEGES ON 数据库名.* TO 账户@"%" IDENTIFIED BY "密码";
flush privileges;

可以测试外网连接 MySQL 服务器。
