MySQL database cannot be remotely logged in to solve the case

Method 1:

Log on to the MySQL Server using the MySQL Adminstrator GUI Tool, but the Server returns the error message Host '60-248-32-13.hinet-ip.hinet.net 'is not allowed to connect to this

MySQL server

This is because of permission issues. The solution is as follows:

Shell> mysql -- user = root-p

Enter Password

Mysql> use mysql

Mysql> grant select, INSERT, UPDATE, delete on [db_name]. * TO [username] @ [ipadd] identified by '[password]';

[Username]: User code for remote login

[Db_name]: indicates the name of the database to be opened to the user.

[Password]: User password for remote login

[Ipadd]: The DNS Name after IP address or IP address reverse lookup. In this example, enter '60-248-32-13.hinet-ip.hinet.net '. Enclose the quotation marks (')

(In fact, it is executed on the remote server. Fill in the IP address of the local host .)

If you want to open all permissions, execute:

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]';

Method 2:

How to solve the connection between the client and the server (mysql): xxx. xxx is not allowed to connect to this mysql serv

1. Go to mysql and create a new user, xuys:

Format: grant permission on database name. Table name user @ login host identified by "User Password ";

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

View the result and execute:

Use mysql;

Select host, user, password from user;

You can see that the created xuys user already exists in the user table. The host field indicates the host to log on to. The value can be an IP address or a host name,

Changing the value of the host field to % indicates that you can log on to the mysql server as an xuys user on any client machine. We recommend that you set the value to % during development.

3../mysqld_safe -- user-root &


Remember: Any modification to the authorization table must be reload again, that is, step 1.

If you still cannot connect from the client after the above three steps, perform the following operations to insert a record in the db table of the mysql database:

Use mysql;

Insert into db values ('2017. 168.88.234 ',' % ', 'xuys', 'y ', 'y', 'y ');

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

Repeat steps 2nd and 3 above.

Method 3:

Add fbysss to connect phpMyAdmin to a remote user:

1. log on to the remote Mysql server with the root account,

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

Update user set host = '%' where user = 'ss ';

Exit mysql and run the command in shell.

# Mysqladmin-u root-p [password] reload

# Mysqladmin-u root-p [password] shutdown

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

2. Modify the config. inc. php file in the phpMyAdmin directory and find

$ Cfg ['servers'] [$ I] ['host'] to the remote server address

$ Cfg ['servers'] [$ I] ['user'] To sss

$ Cfg ['servers'] [$ I] ['Password'] change to sss password

Note that grant all privilege cannot grant the "grant" permission to the user. To add the permission, you can directly use mysql in mysql; update user set Grant_priv = 'y' to meet the requirements.
