如何设置mysql远程访问MySQL远程访问权限,允许远程连接的开启 ? 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 "root"; Query OK, 0 rows affected (0.00 sec) ?www.2cto.com ? 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.
