ERROR 1045 (28000) ERROR solution caused by root@127.0.0.1 (localhost) access when mysql enables skip-name-resolve,
Why do I configure skip-name-resolve?

Because mysql-h $ {ip} remote access is too slow,

mysql -h172.16.66.171 -uroot -p123456

According to user experience (https://www.cnblogs.com/yjf512/p/3803762.html ),

vi /etc/my.cnf

[mysqld]skip-name-resolve

Restart mysql and find that the remote access to msyql is faster.
