通过SQLyog来连接MySQL
(1) 执行File→New connection菜单命令。将打开连接提示对话框。单击New按钮,将创建一个新的连接,给新连接定义一个名字"zyj"
(2) 单击OK按钮,在MySQL的设置窗体输入相关的数据。注意Port是安装MySQL时默认的访问端口,如果安装时未修改,则默认值为3306。
(3) 当单击Test Connection按钮时,将弹出Connection Info对话框。如果提示连接失败,请确定输入的用户名、密码或端口号是否正确。
(4) 当单击"确定"按钮后,就完成了SQLyog与MySQL的连接。接下来就可以通过SQLyog来进行MySQL的相关操作了
1,sqlyog客户端,用root用户远程链接mysql时,提示“访问被拒绝”,在网上搜索了一下原因。 原来是mysql没有授权其远程链接,所以你只能在客户端里面链接。 怎么解决呢? 原表数据 mysql> use mysql mysql> select Host,User,Password from user ; +---------------+---------+-------------------------------------------+ | Host | User | Password | +---------------+---------+-------------------------------------------+ | localhost | root | *DEA65ABECC50A1FEBD9C0D0D9045E0DDB312F38F | | www | root | *DEA65ABECC50A1FEBD9C0D0D9045E0DDB312F38F | | 127.0.0.1 | root | *DEA65ABECC50A1FEBD9C0D0D9045E0DDB312F38F | | ::1 | root | *DEA65ABECC50A1FEBD9C0D0D9045E0DDB312F38F | 创建一个新用户 格式:grant 权限 on 数据库名.表名 to 用户@登录主机 identified by "用户密码"; grant select,update,insert,delete on *.* to komiles@123.4.56.89 identified by "komiles1234"; 执行完上面语句后,再执行 mysql> select Host,User,Password from user ; +---------------+---------+-------------------------------------------+ | Host | User | Password | +---------------+---------+-------------------------------------------+ | localhost | root | *DEA65ABECC50A1FEBD9C0D0D9045E0DDB312F38F | | www | root | *DEA65ABECC50A1FEBD9C0D0D9045E0DDB312F38F | | 127.0.0.1 | root | *DEA65ABECC50A1FEBD9C0D0D9045E0DDB312F38F | | ::1 | root | *DEA65ABECC50A1FEBD9C0D0D9045E0DDB312F38F | | 123.4.56.89 | komiles | *50663F1ECEAB844897BC272EC1AE7E83F442F649 | +---------------+---------+-------------------------------------------+ 此时,就可以用你刚才创建的用户进行远程访问了。 以下是转载http://www.cnblogs.com/smallstone/archive/2010/04/29/1723838.html 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) mysql> select host,user,password from user; +--------------+------+-------------------------------------------+ | host | user | password | +--------------+------+-------------------------------------------+ | localhost | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B | | 192.168.1.12 | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B | | % | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B | +--------------+------+-------------------------------------------+ 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.
