.171 -uroot -p123456

 根据网友经验（https://www.cnblogs.com/yjf512/p/3803762.html），

vi /etc/my.cnf

[mysqld]
skip-name-resolve

重启mysql,发现远程访问msyql速度上来了，解决问题。

 然而引发了新的问题：

但是却发现msyql（mysql -h127.0.0.1 -uroot -p123456）无法本地访问：

[root@localhost ~]#  mysql -h127.0.0.1 -uroot -p123456
Warning: Using a password on the command line interface can be insecure.
ERROR 1045 (28000): Access denied for user ‘root‘@‘127.0.0.1‘ (using password: YES)

而不输入密码（mysql -h127.0.0.1 -uroot）却可以访问。

[root@localhost ~]#   mysql -h127.0.0.1 -uroot 
Welcome to the MySQL monitor.  Commands end with ; or \g.

解决方法：

参考（http://blog.sina.com.cn/s/blog_759a5a7c01017dj0.html），重置root密码：

[root@localhost ~]#   mysql -h127.0.0.1 -uroot

mysql> update user set password=password("123456") where user="root";

mysql> flush privileges;
Query OK, 0 rows affected (0.13 sec)

mysql> quit
Bye
[root@localhost ~]# 

 用 mysql -h127.0.0.1 -uroot -p123456 访问，问题解决。

[root@localhost ~]# mysql -h127.0.0.1 -uroot -p123456
