mysql开启skip-name-resolve 导致root@127.0.0.1…

新老客户大回馈,云服务器低至5折

为什么配置skip-name-resolve?

由于mysql -h${ip} 远程访问速度过慢,

mysql -h172.16.66.171 -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> use mysql;

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

 由于开启skip-name-resolve引发的ERROR 1045 (28000)网上资料不详,解决这个问题花了大半天,所以发布这篇文章。
