mysql user Method implement database solve Remotely

方法一:

  尝试用MySQL Adminstrator GUI Tool登入MySQL Server,Server却回复错误讯息:Host '60-248-32-13.HINET-IP.hinet.net' is not allowed to connect to this

  MySQL server

  这个是因为权限的问题,处理方式如下:

  shell>mysql --user=root -p

  输入密码

  mysql>use mysql

  mysql>GRANT SELECT,INSERT,UPDATE,DELETE ON [db_name].* TO [username]@[ipadd] identified by '[password]';

  [username]:远程登入的使用者代码

  [db_name]:表示欲开放给使用者的数据库称

  [password]:远程登入的使用者密码

  [ipadd]:IP地址或者IP反查后的DNS Name,此例的内容需填入'60-248-32-13.HINET-IP.hinet.net' ,包函上引号(')

  (其实就是在远端服务器上执行,地址填写本地主机的ip地址。)

  如果希望开放所有权限的话请执行:

  mysql>update user set select_priv='Y' , Insert_priv='Y', Update_priv='Y', delete_priv='Y', Create_priv='Y', Drop_priv='Y',Reload_priv='Y', shutdown_priv='Y', Process_priv='Y', File_priv='Y', Grant_priv='Y', references_priv='Y',Index_priv='Y', Alter_priv='Y', Show_db_priv='Y', Super_priv='Y',Create_tmp_table_priv='Y',Lock_tables_priv='Y', Execute_priv='Y',Repl_slave_priv='Y',Repl_client_priv='Y' where user='[username]';

  方法二:

  如何解决客户端与服务器端的连接(mysql) :xxx.xxx.xxx.xxx is not allowed to connect to this mysql serv

  1、进入mysql,创建一个新用户xuys:

  格式:grant 权限 on 数据库名.表名 用户@登录主机 identified by "用户密码";

  grant select,update,insert,delete on *.* to xuys@192.168.88.234 identified by "xuys1234";

  查看结果,执行:

  use mysql;

  select host,user,password from user;

  可以看到在user表中已有刚才创建的xuys用户。host字段表示登录的主机,其值可以用IP,也可用主机名,

  将host字段的值改为%就表示在任何客户端机器上能以xuys用户登录到mysql服务器,建议在开发时设为%。

  3、./mysqld_safe --user-root &


  记住:对授权表的任何修改都需要重新reload,即执行第3步。

  如果经过以上3个步骤还是无法从客户端连接,请执行以下操作,在mysql数据库的db表中插入一条记录:

  use mysql;

  insert into db values('192.168.88.234','%','xuys','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y');

  update db set host = '%' where user = 'xuys';

  重复执行上面的第2、3步。

  方法三:

  附加fbysss解决phpMyAdmin连接远程用户的方法:

  1.用root账户登录远程Mysql服务器,

  grant select,update,insert,delete on *.* to sss@192.168.0.114 identified by "sss";

  update user set host = '%' where user = 'sss';

  退出mysql,在shell下执行

  #mysqladmin -u root -p [password] reload

  #mysqladmin -u root -p [password] shutdown

  #/etc/rc.d/init.d/mysqld start

  2.修改phpMyAdmin目录下的config.inc.php文件,找到

  $cfg['Servers'][$i]['host'] 修改为远程服务器地址

  $cfg['Servers'][$i]['user'] 修改为sss

  $cfg['Servers'][$i]['password']修改为sss的密码

  要注意的是:grant all privilege并不能把“grant” 的权限赋给用户,如果要加,可以直接在mysql中使用use mysql;update user set Grant_priv ='Y'来达到要求。
