1刚操、登陸mysql數(shù)據(jù)庫
mysql -u root -p
查看user表
mysql> use mysql;
Database changed
mysql> select host,user,password from user;
+--------------+------+-------------------------------------------+
| host | user | password |
+--------------+------+-------------------------------------------+
| localhost | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
| 192.168.1.1 | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
+--------------+------+-------------------------------------------+
2 rows in set (0.00 sec)
可以看到在user表中已創(chuàng)建的root用戶。host字段表示登錄的主機(jī)烤芦，其值可以用IP，也可用主機(jī)名悼院，
(1)有時(shí)想用本地IP登錄凛虽，那么可以將以上的Host值改為自己的Ip即可庄新。
2、實(shí)現(xiàn)遠(yuǎn)程連接(授權(quán)法)
將host字段的值改為%就表示在任何客戶端機(jī)器上能以root用戶登錄到mysql服務(wù)器澄峰，建議在開發(fā)時(shí)設(shè)為%嫉沽。
update user set host = ’%’ where user = ’root’;
將權(quán)限改為ALL PRIVILEGES
mysql> use mysql;
Database changed
mysql> grant all privileges on . to root@'%' identified by "root";
Query OK, 0 rows affected (0.00 sec)
mysql>
+--------------+------+-------------------------------------------+
| host | user | password |
+--------------+------+-------------------------------------------+
| localhost | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
| 192.168.1.1 | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
| % | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
+--------------+------+-------------------------------------------+
3 rows in set (0.00 sec)
這樣機(jī)器就可以以用戶名root密碼root遠(yuǎn)程訪問該機(jī)器上的MySql.
3、實(shí)現(xiàn)遠(yuǎn)程連接（改表法）
use mysql;
update user set host = '%' where user = 'root';
這樣在遠(yuǎn)端就可以通過root用戶訪問Mysql.
