Cannot access MySQL database outside

There are two scenarios: 1, MySQL does not assign access to the format:grant  permissions  on  database name. Table name   user @ Login host  identified by  user password; Grant select,update,insert,delete on *.* to [email protected] '% '  identified  by  ' 123456 '; or all rights grant all privileges on *.* to [email  Protected] '% '  IDENTIFIED BY  ' 123456 ';   then execute  flush privileges;  make authorization effective   Finally we need to modify the MySQL configuration file sudo vim /etc/mysql/my. cnf 2, the My.ini configuration does not turn on the network access feature   found in the previous version  skip-networking, just comment it out.   #skip-networking in the new version:# instead of skip-networking  The default is now to listen only on# localhost which is  more compatible and is not less secure. Find  :bind-address            = 127.0.0.1  this line to comment out #bind-address            = 127.0.0.1
