#1

VALIDATE PASSWORD PLUGIN can be used to test passwords...

Press y|Y for Yes, any other key for No: N (我的選項)

#2

Please set the password for root here...

New password: (輸入密碼)

Re-enter new password: (重複輸入)

#3

By default, a MySQL installation has an anonymous user,allowing anyone to log into MySQL without having to havea user account created for them...

Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y (我的選項)   # 若對mysql 不熟悉,建議選N(這樣只要在命令行輸入MySQL,就可以進入MySQL了。)

#4

Normally, root should only be allowed to connect from'localhost'. This ensures that someone cannot guess atthe root password from the network...

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : N (我的選項)  #  我需要遠程使用root目錄,建議選Y(基於安全)。

 

#5

By default, MySQL comes with a database named 'test' thatanyone can access...

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : N (我的選項)

#6

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

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y (我的選項) 

  • 3.配置完成

       

  • 4.查看MySQL的狀態  命令  sudo service mysql status

        active(running)就是正常運行的

      

  • 5.登錄MySQL 命令:mysql -u root -p

    再輸入密碼就好了(輸入密碼屏幕是不會顯示輸入字符的)

    

  • 6.重置MySQL密碼 命令:(需進入MySQL)SET PASSWORD FOR root@'localhost' = PASSWORD('newpassword');
