公司业务服务器还没迁移到阿里云上的时候，创建的一个用户明明是所有的，但是本机登陆就是不行，一直也搞不懂原因
今天才知道 原来 %不包括 localhost
mysql> grant all on salt.* to salt@'%' identified by 'salt';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
[root@saltstack_s yum.repos.d]# mysql -u salt -psaltpasswd@123 -h localhost #登陆不了的原因。是因为上面授权的*不包括localhost
ERROR 1045 (28000): Access denied for user 'salt'@'localhost' (using password: YES)
[root@saltstack_s ~]# mysql -usalt -p -h 192.168.92.128
