How can I set to allow external access to MySQL and set to allow access to mysql?

Set the mysql service to allow Internet access and modify the mysql configuration file, including my. ini and my. cnf and linux ].

1: Set the mysql configuration file
/Etc/mysql/my. cnf
Find bind-address = 127.0.0.1 and comment it out; // This will no longer allow local access only;
 
Restart mysql:/etc/init. d/mysql restart;
 

2: log on to the mysql database: Mysql-u root-p
Mysql> use mysql;
 
Query host values:
Mysql> select user, host from user;
 
If the host value "%" does not exist, execute the following two sentences:
Mysql> update user set host = '%' where user = 'root ';
Mysql> flush privileges;
Or you can execute:
Mysql> grand all privileges on *. * to root @ '%' identifies by 'xxx ';
The first * indicates the database name, and the second * indicates the table name of the database. If it is like the preceding *. *, it indicates that access is allowed from all tables to the database;
'%': Indicates the ip address that is allowed to access mysql. Of course, you can also configure the specific ip address. % indicates that all ip addresses can be accessed;
Followed by 'xxxx' as the root user's password;
 

Example:

Any host is connected to the mysql server with the user root and password mypwd
Mysql> grant all privileges on *. * TO 'root' @ '%' identified by 'mypwd' with grant option;
Mysql> flush privileges;

The host whose IP address is 192.168.1.102 is connected to the mysql server with the user myuser and password mypwd.
Mysql> grant all privileges on *. * TO 'myuser' @ '192. 168.1.102 'identified BY 'mypwd' with grant option;
Mysql> flush privileges;

The root account of mysql. I usually use localhost or 127.0.0.1 during connection. The mysql on the testing server of the company is also localhost. Therefore, I want to access the root account and the test is paused.
Solution:
1. Modify the table, log on to the mysql database, switch to the mysql database, and use the SQL statement to view "select host, user from user ;"
Mysql-u root-pvmwaremysqluse mysql;
Mysqlupdate user set host = '%' where user = 'root ';
Mysqlselect host, user from user;
Mysqlflush privileges; Note: The last sentence is very important to make the modification take effect. If no write is made, remote connection is still unavailable.
2. Authorize the user. You want the root user to use the password to connect to the mysql server from any host.
Grant all privileges on *. * TO 'root' @ '%' identified by 'admin123' with grant option;
Flush privileges;
