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 changedmysql> 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 PRIVILEGESmysql> use mysql;Database changedmysql> grant all privileges on *.* to root@'%' identified by "root";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. 作者 XL.Liang bitsCN.com
