1峻汉、登陸mysql數(shù)據(jù)庫(kù)????
?? 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)爆安，其值可以用IP姆钉，也可用主機(jī)名匙睹，
?? (1)有時(shí)想用本地IP登錄埠啃，那么可以將以上的Host值改為自己的Ip即可送讲。
2奸笤、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)器惋啃，建議在開發(fā)時(shí)設(shè)為%。
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 "password";
Query OK, 0 rows affected (0.00 sec)
mysql>?flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql>?select host,user,password from user;
+--------------+------+-------------------------------------------+
| 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(wèn)該機(jī)器上的MySql.
3监右、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(guò)root用戶訪問(wèn)Mysql.
