1、登陆mysql数据库
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表中已创建的root用户。host字段表示登录的主机,其值可以用IP,也可用主机名,
(1)有时想用本地IP登录,那么可以将以上的Host值改为自己的Ip即可。
2、实现远程连接(授权法)
将host字段的值改为%就表示在任何客户端机器上能以root用户登录到mysql服务器,建议在开发时设为%。
update user set host = '%' where user = 'root';
将权限改为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)
这样机器就可以以用户名root密码root远程访问该机器上的MySql.
3、实现远程连接(改表法)
use mysql; update user set host = '%' where user = 'root';
这样在远端就可以通过root用户访问MySQL,如果大家有任何补充可以联系奥多码小编。
